Abstract
BACKGROUND Dandelion has a great potential to be used as feed additive. Using microbial fermentation technology to degrade cell walls is conducive to enable better release of bioactive compounds of dandelion. This study intended to explore the effect of fermented dandelion (FD) on production performance, meat quality, immune function, and intestinal microbiota of broiler chickens. One-hundred and twenty 1-day-old male Arbor Acres broiler chickens were randomly allotted into three treatments: CON (basal diet, control), LFD and HFD (basal diet with 500 and 1000 mg/kg FD, respectively), with five replicates of eight birds each. The experiment lasted for 42 days. RESULTS The results showed that birds in HFD group had increased ADG during 1-21 days (P < 0.05). On day 21, the bursa of Fabricius index of birds in LFD group was higher (P < 0.05), while the serum contents of IFN-γ and TNF-ɑ were lower in HFD group (P < 0.05). FD supplementation decreased the observed_species, shannon, chao1 and ace indexes (P < 0.05) as well as the abundance of Bacteroidota, Bacteroides, and Alistipes (P < 0.05). Birds in HFD group had higher abundance of Firmicutes and lower abundance of Verrucomicrobiota (P < 0.05). LFD group had lower abundance of unidentified_bacteria (P < 0.05). On day 42, the abdominal fat yield of HFD group was decreased (P < 0.05). Birds in LFD group had lower L* and b* values of breast muscle (P < 0.05), while higher spleen index. The CAT activities of breast muscle of FD groups were higher (P < 0.05). CONCLUSION In summary, dietary FD supplementation at 1000 mg/kg improved production performance and immune function and modulated microbiota composition in ileum of broiler chickens. FD can be supplemented in the diet to enhance performance and health of broiler chickens, of which 1000 mg/kg FD is more effective.

Effects of Traditional Chinese Herbal Feed Additive on Production Performance, Egg Quality, Antioxidant Capacity, Immunity and Intestinal Health of Laying Hens. Animals (Basel) 2023; 13:2510. [PMID: 37570319 PMCID: PMC10417022 DOI: 10.3390/ani13152510] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Revised: 07/25/2023] [Accepted: 08/01/2023] [Indexed: 08/13/2023] Open
Abstract
Chinese herbs have been used as feed additives in animal production. This study investigated the effects of a Chinese herbal feed-additive (TCM, which contained Elsholtzia ciliate, Atractylodes macrocephala, Punica granatum pericarpium, and Cyperus rotundus) on the production performance, egg quality, antioxidant capacity, immunity, and intestinal health of Roman laying hens. A total of 720 28-week-old hens were randomly allotted to three groups with six replicates of forty hens each. The groups were fed a basal diet (CON group), a basal diet with 50 mg/kg zinc bacitracin (ABX group), or a basal diet with 400 mg/kg TCM (TCM group) for 56 days. The results showed that the TCM group increased egg production, egg mass, albumen height, and Haugh unit compared with the CON group (p < 0.05). There were no significant differences in egg weight, feed intake, feed conversion rate, and eggshell strength among all three groups (p > 0.05). Compared with the CON group, the TCM group enhanced the activities of glutathione peroxidase, total antioxidant capacity, and superoxide dismutase in serum and liver, and reduced malondialdehyde content (p < 0.05). The TCM also increased the levels of interleukin-2, interferon-γ, immunoglobulin A, immunoglobulin M, and immunoglobulin G, and decreased the levels of interleukin-6 and interleukin-8 compared with the CON group (p < 0.05). Furthermore, the TCM group increased jejunal goblet cell density and decreased ileal crypt depth and lymphocyte density compared with the CON group (p < 0.05). The results of 16S rRNA demonstrated that the TCM can change the diversity and composition of intestinal microbiota. At the phylum level, the abundance of Bacteroides increased while that of Firmicutes decreased in the TCM group (p > 0.05). At the genus level, the abundance of Lactobacillus, Rikenellaceae_RC9_gut_group, and Phascolarctobacterium increased while that of Bacteroides and unclassified_o__Bacteroidales decreased in the TCM group (p > 0.05). The effects of ABX were weaker than those of the TCM. In conclusion, the TCM has positive effects on production performance and the intestinal health of hens.

Abstract
The purpose of this study was to evaluate the effects of dietary Glycyrrhiza polysaccharide (GCP) on growth performance, blood parameters and immunity in weaned piglets. A total of 240 (10.33 ± 0.62 kg body weight) 35-day-old (Duroc × Landrace × White) weaned piglets were randomly assigned to four dietary treatments, with six replicate pens per treatment and 10 piglets per pen (five males and five females). The dietary treatments continued for 21 days and comprised a basal diet supplemented with 0 (control group), 500, 1000 and 2000 mg/kg GCP. The results showed that the inclusion of 1000 and 2000 mg/kg GCP increased the average daily gain and decreased the feed conversion rate compared with the control group (p < 0.05). The piglets treated with 500 and 1000 mg/kg GCP had a lower diarrhoeal incidence than the control group (p < 0.05). Moreover, supplementation with 1000 mg/kg GCP increased the counts of white blood cells, neutrophils, red blood cells, and platelets, and elevated alkaline phosphatase, total protein, globulin, glucose, triglyceride, immunoglobulin A, immunoglobulin G, and total antioxidant capacity levels (p < 0.05), and decreased malondialdehyde content compare with the control group (p < 0.05). In addition, relative to the control group, piglets fed 500 and 1000 mg/kg GCP had significantly lower expression of interleukin-6 mRNA in spleen (p < 0.05). Our results indicate that dietary supplementation with GCP can improve growth performance, blood parameters and immunity in weaned piglets. Our study suggests that adding 1000 mg/kg GCP to the diet had the most beneficial effect.

Abstract
In animal husbandry, traditional Chinese medicine (TCM) as a reasonable alternative to antibiotics has attracted more and more concerns to reduce microbial resistance. This study was aimed to investigate the effects of dietary supplementation with TCM prescriptions on serum parameters and thymus inflammation responses in finishing pigs. Thirty finishing pigs were randomly divided into three groups, which included the Con group (basal diet), the TCM1 group (basal diet supplemented with Xiao Jian Zhong prescriptions), and the TCM2 group (basal diet supplemented with Jingsananli-sepsis). The results showed that the contents of C3 and C4 in the serum were significantly increased in both the TCM1 and TCM2 groups compared to the Con group on day 30. Similarly, the levels of IgA, IgG, and IgM were increased in the TCM2 group, and only the level of IgM in TCM1 was increased on day 30. Meanwhile, the levels of classical swine fever virus (CSFV) and respiratory syndrome virus (PRRSV) antibodies had a notable increase in the TCM1 and TCM2 groups. Both TCM1 and TCM2 inhibited the levels of TLR4/MyD88/NF-κB signaling pathway-related mRNA (TLR4, MyD88, NF-κB, IL6, IL8, and TNF-α) and protein (p-IκBα and p-P65) expression levels in the thymus. In conclusion, dietary supplementation with TCM could reduce thymic inflammation levels and improve humoral immunity of finishing pigs.

Abstract
This study was conducted to evaluate the effects of dietary supplementation with Glycyrrhiza polysaccharide (GCP) on growth performance, serum biochemistry, immunity, and egg laying in female quail. 300 1-day-old female quail were sorted into four dietary treatments with five replicate cages of 15 birds each. The basic diet in the four treatment groups was supplemented with 0, 500, 1000 and 1500 mg/kg GCP, and the experiment continued for 80 days. Results showed that dietary supplementation with GCP significantly (p < 0.05) increased average daily gain in a dose-dependent fashion, and decreased (p < 0.05) the feed-to-gain ratio and mortality. The relative weights of the thymus and bursa of Fabricius increased (p < 0.05) linearly with increasing dose of GCP from 0 to 1500 mg/kg on day 20. GCP birds showed higher serum levels of protein, glucose, immunoglobulin A and immunoglobulin M, but lower serum triglycerides (p < 0.05) on day 50. GCP increased (p < 0.05) average laying rate and average egg weight linearly from days 60 to 80, whereas feed to egg ratio was decreased (p < 0.05). Taken together, these results revealed that GCP could improve growth performance, serum biochemistry, immunity, and egg laying in female quail. Therefore, GCP may be a potential replacement for antibiotic growth promoters in poultry.

Abstract
The specific concentrations of tetracycline, chlortetracycline, oxytetracycline and doxycycline in non-target feed for food-producing animals, below which there would not be an effect on the emergence of, and/or selection for, resistance in bacteria relevant for human and animal health, as well as the specific antimicrobial concentrations in feed which have an effect in terms of growth promotion/increased yield were assessed by EFSA in collaboration with EMA. Details of the methodology used for this assessment, associated data gaps and uncertainties are presented in a separate document. To address antimicrobial resistance, the Feed Antimicrobial Resistance Selection Concentration (FARSC) model developed specifically for the assessment was applied. The FARSC for these four tetracyclines was estimated. To address growth promotion, data from scientific publications obtained from an extensive literature review were used. Levels in feed that showed to have an effect on growth promotion/increased yield were reported for tetracycline, chlortetracycline, oxytetracycline, whilst for doxycycline no suitable data for the assessment were available. Uncertainties and data gaps associated with the levels reported were addressed. It was recommended to perform further studies to supply more diverse and complete data related to the requirements for calculation of the FARSC for these antimicrobials.

Abstract
Fatty liver hemorrhage syndrome (FLHS) is the most common noninfectious cause of death in backyard chickens worldwide, which can cause a sudden drop in egg production in the affected flocks and cause huge losses to the laying hens breeding industry. In this study, we prepared polysaccharide from Atractylodes macrocephala Koidz (PAMK) by one-step alcohol precipitation. The structural analysis found that PAMK with a molecular weight of 2.816 × 103 Da was composed of glucose and mannose, in a molar ratio of 0.582 to 0.418. Furthermore, we investigated the hepatoprotective effects of PAMK on high-energy and low-protein (HELP) diet-induced FLHS in laying hens. The results showed that the hens' livers of the HELP diet showed yellowish-brown, greasy, and soft, whereas the supplement of PAMK (200 mg/kg or 400 mg/kg) could alleviate such pathological changes. The liver index, the abdominal fat percentage, and liver injury induced by the HELP diet were reduced in PAMK (200 mg/kg or 400 mg/kg). Supplementing 200 mg/kg or 400 mg/kg PAMK showed improvements of the antioxidant capacity in laying hens. Furthermore, we found that the HELP diet increased the expression of hepatic lipogenesis genes and decreased the expression of fatty acid β-oxidation genes, which could be reversed by 200 mg/kg or 400 mg/kg PAMK supplementation. Nevertheless, there is no difference between the addition of 40 mg/kg PAMK and the HELP group. Collectively, these results showed that PAMK supplements could ameliorate HELP diet-induced liver injury through regulating activities of antioxidant enzymes and hepatic lipid metabolism. Therefore, PAMK could be a potential feedstuff additive to alleviate FLHS in laying hens.

Research Note: Effects of polysaccharide-enriched Acanthopanax senticosus extract on growth performance, immune function, antioxidation, and ileal microbial populations in broiler chickens. Poult Sci 2021; 100:101028. [PMID: 33647719 PMCID: PMC7921867 DOI: 10.1016/j.psj.2021.101028] [Citation(s) in RCA: 33] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2020] [Revised: 12/16/2020] [Accepted: 01/01/2021] [Indexed: 11/22/2022] Open
Abstract
Acanthopanax senticosus (AS) is a well-known, highly effective traditional Chinese herbal medicine. Polysaccharides extracted from AS (ASPS) have multiple pharmacologic and biological activities with potential use as additives in broiler chicken feed. This trial evaluated the effects of dietary ASPS on growth performance, immune function, antioxidation, and ileal microbial populations in broiler chickens. A total of 240 1-day-old Arbor Acres male broiler chicks were randomly divided into 4 groups, with 10 replicates of 6 chicks and fed a corn- and soybean-based diet supplemented with 0, 1, 2, or 4 g/kg ASPS. Compared with the control group, supplementation with 1 g/kg ASPS increased ADG and ADFI in the finisher and overall periods and decreased the feed conversion ratio in the finisher period (both P < 0.05). Serum IgA and IgM were significantly increased by supplementation with 1 and 2 g/kg of ASPS (P < 0.05). Superoxide dismutase and glutathione peroxidase activities were increased and malondialdehyde concentration was decreased in birds fed ASPS-supplemented diets compared with those in the control group (P < 0.05). Polysaccharides extracted from AS supplementation increased Lactobacillus and decreased Escherichia coli and Salmonella counts in the ileal contents compared with the control diet (both P < 0.05). The results show that dietary ASPS improved growth performance, immune status, and antioxidant capacity and stimulated the growth of beneficial gut bacteria in broiler chickens. In conclusion, ASPS was effective as a natural additive in broiler chicken feed; 1 g/kg can be considered as the optimum dosage.

Dietary combined supplementation of iron and Bacillus subtilis enhances reproductive performance, eggshell quality, nutrient digestibility, antioxidant capacity, and hematopoietic function in breeder geese. Poult Sci 2020; 99:6119-6127. [PMID: 33142530 PMCID: PMC7647764 DOI: 10.1016/j.psj.2020.06.077] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2020] [Revised: 06/13/2020] [Accepted: 06/16/2020] [Indexed: 02/04/2023] Open
Abstract
A 3 × 2 factorial arrangement of treatments was conducted to investigate the effects of iron (Fe, 40, 60, and 80 mg/kg) and Bacillus subtilis (2.5 × 109 and 5.0 × 109 CFU/kg) supplementation on reproductive performance, egg quality, nutrient digestibility, hormone levels, antioxidant indices, and hematological parameters in breeder geese. A total of one hundredtwenty 46-week-old Wulong breeder geese were randomly assigned to 1 of 6 dietary treatments with 4 replicates per treatment and 5 geese per replicate for 10 wk following 1 wk of adaption. Dietary Fe supplementation increased egg weight (P = 0.036), fertility (P = 0.022), serum total antioxidant capacity (P = 0.022), red blood cell (P = 0.001), hematocrit (HCT, P < 0.001), hemoglobin (HGB, P = 0.005), and mean corpuscular volume (MCV, P < 0.001). Dietary B. subtilis supplementation increased egg production (P = 0.025), eggshell thickness (P = 0.020), apparent phosphorus digestibility (P < 0.001), serum follicle stimulating hormone (P = 0.043), total antioxidant capacity (P < 0.001), HCT (P < 0.001), HGB (P < 0.001), and MCV (P = 0.025), and reduced malondialdehyde level (P = 0.008). The birds fed diets supplemented with 60 mg/kg Fe and 5 × 109 CFU/kg B. subtilis showed the highest percentage of hatched eggs (P = 0.004) and mean corpuscular hemoglobin (P < 0.001) among the 6 groups. Supplementation of 40 and 60 mg/kg Fe significantly increased the apparent digestibility of calcium compared with that of 80 mg/kg Fe in the birds fed 5.0 × 109 CFU/kg B. subtilis (P = 0.004). Supplementation with 60 and 80 mg/kg Fe in the birds fed 5 × 109 CFU/kg B. subtilis significantly decreased serum urea nitrogen level compared with other 4 groups (P = 0.022). In conclusion, the combination of Fe and B. subtilis effectively improves reproductive performance, eggshell quality, nutrient digestibility, antioxidant status, and hematopoietic function of breeder geese. Dietary addition of 60 mg/kg Fe and 5.0 × 109 CFU/kg B. subtilis was an optimum supplementation dose.

Effects of Achyranthes bidentata polysaccharides on performance, immunity, antioxidant capacity, and meat quality in Pekin ducks. Poult Sci 2020; 99:4884-4891. [PMID: 32988525 PMCID: PMC7598114 DOI: 10.1016/j.psj.2020.06.026] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2019] [Revised: 05/07/2020] [Accepted: 06/13/2020] [Indexed: 11/23/2022] Open
Abstract
This study was conducted to evaluate the effects of Achyranthes bidentata polysaccharide (ABP) on growth performance, antioxidant capacity, immune function, relative organ weight, ileal microflora, and meat quality in Pekin ducks. A total of 1,200 female 1-day-old Pekin ducklings (51.2 ± 0.2 g) were blocked based on body weight (BW) and randomly allocated into 3 treatments with 10 replicates of 40 birds each. The experiment lasted for 6 wk, and dietary treatments included corn–soybean meal–based diet supplemented with 0, 0.02, and 0.04% ABP. The supplementation of ABP increased (P < 0.05) body weight gain (BWG) and final BW linearly during day 22 to 42 and day 1 to 42, respectively, but decreased (P < 0.05) feed-to-gain ratio (F/G) linearly during day 22 to 42 and day 1 to 42. The inclusion of ABP increased (P < 0.05) serum superoxide dismutase, glutathione peroxidase, total antioxidative capacity, catalase, complement3, complement4, immunoglobin A, immunoglobin G, interleukin-2, interferon-γ, and tumor necrosis factor-α linearly. The relative weight of breast meat was increased (P < 0.05) linearly, but the relative weight of abdominal fat was decreased (P < 0.05) linearly with the increasing dietary ABP supplementation. The supplementation of ABP increased (P < 0.05) ileal Lactobacilli counts linearly, whereas decreased (P < 0.05) Escherichia coli counts linearly. Taken together, the inclusion of ABP promoted BWG and final BW during day 22 to 42 and the entire experiment, decreased F/G during day 22 to 42 and day 1 to 42, and partially improved antioxidant activities, immunity, and gut microflora in Pekin ducks.

Abstract
Hippophae rhamnoides L. polysaccharide (HRP) has antioxidant and immunomodulatory actions. It has been reported that HRP can reduce the release of reactive oxygen species (ROS). The objective of this study was to investigate the effects of HRP on immunomodulatory and antioxidant activity in intestinal porcine jejunum epithelial (IPEC-J2) cells. Effective conditions of HRP (0, 200, 400, 600, and 800 μg mL−1) were evaluated by pretreatment of IPEC-J2 cells for 24 h. The results showed that pretreatment with 0–600 μg mL−1 of HRP enhanced cell survival rate, while more than 600 μg mL−1 posed a threat to IPEC-J2 cell viability and lowered cell survival rate (p < 0.05). In addition, results revealed that, compared with the control group, the treatment of IPEC-J2 cells with 200–600 μg mL−1 of HRP for 24 h decreased ROS, malondialdehyde, protein carbonyl levels, and cell apoptosis. Meanwhile, the levels of superoxide dismutase, glutathione peroxidase, interleukin-1 beta, interleukin-2, interleukin-6, interleukin-8, tumour necrosis factor-alpha were elevated, and enhanced relative mRNA levels were also shown in the IPEC-J2 cells. Both the contents of immunoglobulin M, immunoglobulin A, and immunoglobulin G elevated with the increases of HRP concentration (200, 400, and 600 μg mL−1), and an increase of catalase relative mRNA levels were also observed in IPEC-J2 cells. Data indicated that 600 μg mL−1 of HRP had a potent protective effect on IPEC-J2 cells. Taken together, these results suggested that HRP was effective in regulating intestinal epithelial cells in piglets.

Abstract
Context
Grapeseed procyanidins (GSP) are widely recognised to have potential biological properties, and dietary supplementation with GSP could reduce diarrhoea incidence in weaned piglets.
Aims
This trial was conducted to investigate the effect of GSP on small intestinal mucosa morphology and small intestinal development in weaned piglets.
Methods
Seventy-two weaned piglets were randomly allocated into four dietary groups with three replicate pens per group and six piglets per pen. Each group received one of the following diets: a basal maize–soybean meal diet; or basal diet supplemented with 50, 100 or 150 mg GSP/kg. Small intestinal mucosa morphology and the expression of genes involved in improving small intestinal development were determined.
Key results
Morphological observations obtained by optical microscopy showed that the villus height of the duodenum and ileum increased in all groups receiving GSP, significantly (P < 0.05) so in the group receiving 100 mg GSP/kg compared with the control group. Crypt depth of the duodenum and ileum in the groups receiving 100 and 150 mg GSP/kg decreased compared with the control group. Similarly, the crypt depth of the jejunum in the group receiving 100 mg GSP/kg was significantly (P < 0.05) lowered. Moreover, the villus height/crypt depth ratio of each small intestinal segment in the group receiving 100 mg GSP/kg increased significantly (P < 0.01). Morphological observations obtained by scanning electron microscopy indicated that dietary supplementation with GSP was favourable for growth of small intestinal villi. Specifically, the villi of the small intestine in the group receiving 100 mg GSP/kg were most closely aligned, most uniform in size and clearest in structure. Furthermore, dietary supplementation with GSP increased the expression of genes encoding epidermal growth factor receptor, insulin-like growth factor 1 (IGF-1) and IGF-1 receptor in the duodenum, the group receiving 100 mg GSP/kg showing a significant (P < 0.05) increase.
Conclusions
Dietary supplementation with GSP could improve small intestinal mucosa morphology and promote small intestinal development. Dietary supplementation of 100 mg GSP/kg could be recommended for weaned piglets.
Implications
Dietary supplementation with GSP generated a beneficial role in small intestinal health in weaned piglets.

Animals (Basel) 2019; 10:ani10010035. [PMID: 31878017 PMCID: PMC7022547 DOI: 10.3390/ani10010035] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2019] [Revised: 12/17/2019] [Accepted: 12/17/2019] [Indexed: 02/05/2023] Open
Abstract
In this study, the effect of dietary supplementation of mulberry leaf polysaccharides (MLPs) on the immune parameters-i.e., the immune organ weight, serum immunoglobulins, cytokines, nitric oxide (NO) production, and insulin-Like growth factor-1 (IGF1) mRNA expression-of weanling pigs as a model animal was investigated. A total of 120 healthy weanling pigs (aged 28 ± 2 d) with the same body weights were randomly divided into four groups: (1) Control treatment (CT), basal diet (BD), (2) MLP low-dose treatment (MLT), 0.6 g/kg MLP + BD, (3) MLP high-dose treatment (MHT), 1.2 g/kg MLP + BD, and (4) antibiotic treatment (AT), 0.15 g/kg chlortetracycline + BD. The results revealed that the thymus and spleen indices were significantly increased (P < 0.05) in both MLT and MHT groups in comparison with the CT group, while the serum levels of immunoglobulin G (IgG), interleukin (IL)-1β, IL-2, IL-8, and interferon (IFN-γ) in the MLT group and IL-2, IL-6, and IFN-γ in the MHT group were also considerably greater (P < 0.05) than the corresponding levels in the CT group. The serum contents of IgG, IL-1β, IL-2, and IL-8 in the MLT group and IL-2 and IL-6 in the MHT group were significantly increased in comparison with the corresponding contents in the AT group (P < 0.05). The transformation rate of lymphocytes in the MLT and MHT groups was higher compared to the CT and AT groups. However, a notable difference was found between the MLT group and the two control groups. The peripheral lymphocyte NO production in the MLT, MHT, and AT groups was significant relative to the CT group. The expression levels of IGF1 mRNA in the liver and muscle longissimus tissues of both the MLT and MHT groups showed significant improvement (P < 0.05) over those in the CT group. Moreover, the IGF1 mRNA expression in the muscle longissimus from the MLT group was significantly higher than in the AT group. In conclusion, the results suggest that incorporating MLPs into the diets of weanling pigs improves the animals' metabolisms and immune functions, and the effects of the MLT group were superior to those of both the MHT and AT groups.

Abstract
Lycium barbarum polysaccharides (LBP) are considered to be the major bioactive components of L. barbarum and have been widely used as a well-known traditional Chinese medicine and functional food because of their various biological activities. However, no published research has investigated the use of LBP as a feed additive in broilers. The objective of this study was to evaluate the effects of dietary LBP supplementation on the growth performance, digestive enzyme activities, antioxidant status, and immunity of broiler chickens. A total of 256 one-day-old Arbor Acres male broiler chicks were randomly allotted into 4 groups, with 8 replicates of 8 birds each, and were fed a corn-soybean meal-type basal diet supplemented without (control group) or with 1,000, 2,000, or 4,000 mg/kg LBP for 6 wk. The results showed that compared with the control diet, a significant increase in ADG (P < 0.05) during the grower and overall periods was observed in chickens fed the basal diet supplemented with 2,000 mg/kg LBP, whereas supplementation with 1,000 or 2,000 mg/kg LBP decreased feed-to-gain ratio (P < 0.05) during the starter period. The inclusion of LBP in the broiler diets increased overall amylase, lipase, and protease activities (P < 0.05). Supplementation with increasing levels of dietary LBP increased the activities of superoxide dismutase and glutathione peroxidase but decreased malondialdehyde content in the serum and liver (P < 0.05). Broilers fed with LBP-containing diets exhibited higher serum IgG and IgA concentrations (P < 0.05) than the broilers fed with the control diet. Serum tumor necrosis factor α and IL-4 concentrations were significantly elevated in the group fed 2,000 mg/kg LBP compared with the control group (P < 0.05). Broilers fed diets supplemented with LBP showed linear (P < 0.05) and quadratic (P < 0.05) increases in serum IL-6 and interferon gamma concentrations. The results indicated that dietary LBP supplementation can improve growth performance, digestive enzyme activities, antioxidant capacity, and immune function of broilers. In conclusion, LBP may be used as a promising feed additive for broilers, and a supplementation level of 2,000 mg/kg LBP in the broiler diet is recommended.

Abstract
Lycium barbarum polysaccharides (LBPs) are a complex mixture of highly branched and partially characterised polysaccharides and proteoglycans extracted from the goji berry. This mixture has great potential as a novel feed supplement for pigs. Two trials were conducted to evaluate the effects of supplementation with LBPs on the growth performance, immune status, antioxidant capacity and selected intestinal microbial populations in weaned piglets. In trial 1, a total of 400 weaned piglets [(Yorkshire × Landrace) × Duroc] with an average body weight (BW) of 6.34 ± 0.16 kg (21 days of age) were divided into five groups and fed a basal diet (control group) or a basal diet containing 1,000, 2,000, 4,000 or 6,000 mg/kg LBPs (supplemented at the expense of corn). Supplementation with 4,000 or 6,000 mg/kg LBPs for 2 weeks significantly increased the average daily gain (ADG) and average daily feed intake (ADFI) of the pigs compared with the control group (p < .05). In trial 2, thirty-two 21-days-old weaned piglets (BW: 6.33 ± 0.11 kg) were allotted to a control group (fed with a basal diet) or an experimental group (basal diet containing 4,000 mg/kg LBPs). The experiment lasted for 14 days. Pigs fed LBP diets exhibited an increased ADG and ADFI, and a decreased diarrhoeal incidence compared with those fed the basal diets (p < .05). Supplementation with LBPs increased the serum IgG and IgM levels (p < .05). Dietary LBPs effectively promoted antioxidant defence properties through enhancing the activities of serum, liver superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px), in addition to decreasing the malondialdehyde (MDA) content (p < .05). The addition of LBPs increased the amounts of Bacteroidetes in the ileum and caecum and the caecal contents of Lactobacillus spp. and Bifidobacterium spp. (p < .05), while decreased the populations of Escherichia coli and Firmicutes in the ileum and caecum (p < .05) compared with the control group. Our results suggest that dietary supplementation with LBPs can enhance growth performance, immune status and antioxidant capacity, and improve the intestinal microbial populations of weaned piglets.

Abstract
Antibiotics are commonly provided to weaned piglets; however, this practice has become controversial due to the increased occurrences of microbial resistance, and alternatives are needed. This study aimed to investigate the effects of dietary supplementation with yeast glycoprotein (YG) on growth performance, intestinal mucosal morphology, immune response and colonic microbiota in weaned piglets. A total of 240 weaned piglets (d 23 ± 2) from 16 pens (15 piglets per pen) were randomly allocated to an antibiotics group (25% quinocetone 200 mg kg-1 and 4% enduracidin 800 mg kg-1 of the basal diet) or a YG group (800 mg kg-1 YG of the basal diet), respectively. The trial lasted 14 days, and at the end of the trial, one piglet per pen was chosen to collect plasma, intestinal tissue and colonic digesta samples. The results indicate that piglets fed diets containing YG tended to show increased final body weight (0.05 < P < 0.1), increased average daily gain (P < 0.05) and decreased F/G (P < 0.05) when compared with the antibiotics group. Moreover, intestinal permeability showed that YG led to an improvement in the intestinal development via decreasing serum content of DAO (P < 0.01). Histological evaluations showed that YG contributed to the improvement of the intestinal development via increasing villous height (P < 0.05) and the villous height to crypt depth ratio (P < 0.01), and decreasing crypt depth (P < 0.01) and villous width (P < 0.05) in the ileum. Intestinal integrity also showed that YG was conducive to improvement of the intestinal development via upregulating the m-RNA expression of occludin (P < 0.05) in the duodenal and jejunal mucosa. Interestingly, YG supplementation downregulated the m-RNA expression of IL-12 (P < 0.05), upregulated the m-RNA expression of Hsp-70 (P < 0.05) in the duodenal mucosa, downregulated the m-RNA expression of Hsp-70 (P < 0.05) and IFN-γ (P < 0.05), upregulated the m-RNA expression of Hsp-90 (P < 0.05) in the jejunal mucosa, and upregulated the m-RNA expression of Hsp-70 (P < 0.05) in the ileal mucosa. On the other hand, colonic microbiota results showed that YG supplementation increased the relative abundance of Lactobacillus (P < 0.05) in the genus level. Colonic metabolite results showed that YG supplementation decreased the content of acetate (P < 0.05). Taken together, it is speculated that YG would be a potent alternative to prophylactic antibiotics in improving the gut health in weaned piglets.

Abstract
Grape seed procyanidins (GSPs), widely known for their beneficial health properties, fail to bring about the expected improvement in piglets' growth performance. The effects of dietary supplementation with GSPs on nutrient utilisation may be a critical influencing factor. Hence, the purpose of this study was to investigate the effects of dietary supplementation with GSPs on nutrient utilisation and gut function in weaned piglets. One hundred and twenty crossbred piglets were allocated randomly to four treatment groups, with three replicate pens per treatment and 10 piglets per pen. Each group was given one of the four dietary treatments: the basal diet (control group) or the basal diet with the addition of 50-, 100- or 150-mg/kg GSPs. The trial lasted 28 days. Faeces were collected from d 12 to 14 and from d 26 to 28 for measuring the coefficient of total tract apparent digestibility (CTTAD) of the nutrients. Blood samples were collected on d 14 and 28 for detecting the blood biochemical parameters. Two piglets per pen were slaughtered to collect the pancreas and intestinal digesta for evaluating the digestive enzyme activity and the coefficient of ileal apparent digestibility (CIAD) of the nutrients. On d 14 and 28, supplementation with 150-mg/kg GSPs significantly decreased the CTTAD of DM and CP in piglets. On d 14, GSPs supplementation at a concentration of 150 mg/kg led to a remarkable decrease in the CIAD of CP and gross energy (GE). On d 28, GSPs supplementation at a dose of 150 mg/kg generated a marked decline in the CIAD of DM, GE, CP and ether extract. Grape seed procyanidins supplementation at concentrations of 100 or 150 mg/kg inhibited the activities of lipase and amylase. In contrast, the jejunum mucosa maltase and sucrase activities increased due to the inclusion of GSPs at a concentration of 100 mg/kg in the piglet diet. Compared with the levels of the control group, the serum glucose and total protein levels were enhanced significantly by supplementation with GSPs at 100 mg/kg and reduced dramatically at 150 mg/kg. The serum diamine oxidase activity and endotoxin levels were decreased by GSPs supplementation in piglet diets. In conclusion, higher concentrations of GSPs in weaned piglet diets attenuated nutrient digestion and inhibited digestive enzyme activity; however, suitable concentrations of GSPs could promote brush-border enzyme activity, enhance serum glucose and total protein concentrations and decrease epithelial permeability.

Abstract
BACKGROUND Pleurotus ostreatus mushroom (POM) is an edible mushroom with rich nutritional components and vital pharmacological properties. The present study comprised 100 cross-bred piglets, weaned at 28 days old, who were randomly assigned to four POM diets with five replicates per diet and five piglets per pen. RESULTS POM supplementation (P < 0.05) decreased the incidence of diarrhea, and also increased the average daily feed intake and average daily gain of pigs. Fecal acetate, butyrate and propionate increased with the addition of POM. Interleukin-2, immunoglobulin G, immunoglobulin M, tumor necrosis factor-α and immunoglobulin A increased (P < 0.05) with the addition of POM. The 16S rDNA sequencing results showed that the Bacteroidetes and Firmicutes were the dominant microbial strains in the fecal samples, irrespective of POM supplementation. Shannon diversity, whole tree phylogenetic diversity, observed species and Chao1 analysis exhibited significant variation in species richness across the treatments. Principal coordinates analysis showed a significant (P < 0.1) increase in the microbial communities amongst all of the treatment groups. CONCLUSION The results of the present study suggest that the supplementation of POM in the diet of piglets might increase feed consumption, gut microbial composition and diversity, as well as short-chain fatty acids synthesis, consequently preventing the occurrence of diarrhea and increasing the growth of piglets. © 2019 The Authors.

Abstract
Astragalus membranaceus is an herbaceous perennial plant, growing to about 2 feet tall, with sprawling stems and alternate leaves about 12-24 leaflets. In total, 24 cross bred (Duroc × Landrace × Yorkshire) piglets weaned at 4 weeks with an average body weight of 10.84 ± 1.86 kg, were divided into four groups and randomly assigned to dietary treatments containing different AMSLF levels (0.00%, 2.50%, 5.00%, and 7.50%). The piglets in the control group (0.00% AMSLF) were fed basal diet and other treatment groups were fed basal diet in addition to 2.50%, 5.00%, and 7.50% pulverized AMSLF. The results indicated that supplementation with AMSLF significantly (p < 0.05) decreased diarrheal incidence in piglets. There was significant difference between treatment in terms of ADFI, ADG and FCR. Both 5.00% and 7.50% treatments significantly increased growth performance. The digestibility of gross energy and dry matter increased (p > 0.05) with increasing AMSLF level. The level of blood IL-2 and TNF-α were significantly affected by AMSLF supplementation with 7.50% AMSLF group having higher (p < 0.05) IL-2 and TNF-α levels than the other treatment groups. The 16SrDNA sequencing results from the four treatments showed that the potentially active bacterial microbial population and diversity in pig cecum were dominated by the phyla Bacteriodetes and Firmicutes regardless of the AMSLF supplementation. The Shannon diversity, PD whole tree diversity indices and Chao analyses exhibited significant variability in species richness across the treatments. The principal coordinates analysis (PCoA) showed significant (p < 0.1) differences between bacterial communities in all treatment groups. Results from the current study suggested that AMSLF supplementation increased composition of bacterial microbiota in pig gut. In conclusion, dietary supplements with AMSLF could potentially be used to prevent diarrheal incidence and improved pig production.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Atractylodes macrocephala Koidz. (called Baizhu in China) is a medicinal plant that has long been used as a tonic agent in various ethno-medical systems in East Asia, especially in China, for the treatment of gastrointestinal dysfunction, cancer, osteoporosis, obesity, and fetal irritability. AIM OF THE REVIEW This review aims to provide a systematic summary on the botany, traditional uses, phytochemistry, pharmacology, pharmacokinetics, and toxicology of A. macrocephala to explore the future therapeutic potential and scientific potential of this plant. MATERIALS AND METHODS A literature search was performed on A. macrocephala using scientific databases including Web of Science, Google Scholar, Baidu Scholar, Springer, PubMed, SciFinder, and ScienceDirect. Information was also collected from classic books of Chinese herbal medicine, Ph.D. and M.Sc. dissertations, unpublished materials, and local conference papers on toxicology. Plant taxonomy was confirmed to the database "The Plant List" (www.theplantlist.org). RESULTS More than 79 chemical compounds have been isolated from A. macrocephala, including sesquiterpenoids, triterpenoids, polyacetylenes, coumarins, phenylpropanoids, flavonoids and flavonoid glycosides, steroids, benzoquinones, and polysaccharides. Crude extracts and pure compounds of A. macrocephala are used to treat gastrointestinal hypofunction, cancer, arthritis, osteoporosis, splenic asthenia, abnormal fetal movement, Alzheimer disease, and obesity. These extracts have various pharmacological effects, including anti-tumor activity, anti-inflammatory activity, anti-aging activity, anti-oxidative activity, anti-osteoporotic activity, neuroprotective activity, and immunomodulatory activity, as well as improving gastrointestinal function and gonadal hormone regulation. CONCLUSIONS A. macrocephala is a valuable traditional Chinese medicinal herb with multiple pharmacological activities. Pharmacological investigations support the traditional use of A. macrocephala, and may validate the folk medicinal use of A. macrocephala to treat many chronic diseases. The available literature shows that much of the activity of A. macrocephala can be attributed to sesquiterpenoids, polysaccharides and polyacetylenes. However, there is a need to further understand the molecular mechanisms and the structure-function relationship of these constituents, as well as their potential synergistic and antagonistic effects. Further research on the comprehensive evaluation of medicinal quality, the understanding of multi-target network pharmacology of A. macrocephala, as well as its long-term in vivo toxicity and clinical efficacy is recommended.

The protective effects of polysaccharide of Atractylodes macrocephala Koidz (PAMK) on the chicken spleen under heat stress via antagonizing apoptosis and restoring the immune function. Oncotarget 2017; 8:70394-70405. [PMID: 29050288 PMCID: PMC5642563 DOI: 10.18632/oncotarget.19709] [Citation(s) in RCA: 36] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2017] [Accepted: 06/28/2017] [Indexed: 01/03/2023] Open
Abstract
Heat stress can cause immune organ dysfunction and apoptosis. Polysaccharide of Atractylodes macrocephala Koidz may have protective effects on immune organs. In this study, we established chicken models of Polysaccharide of Atractylodes macrocephala Koidz-heat stress interaction and detected the oxidative index, activities of mitochondrial complexes and ATPases as well as the ultrastructure in chicken spleens. Expression levels of cytokines, mitochondrial dynamics- and apoptosis-related genes were also measured. In the result, heat stress increased the expression of interleukin 1 and tumour necrosis factor-alpha and decreased that of interleukin 2 and interferon gamma. The activities of mitochondrial complexes and ATPases were decreased and oxidative stress was induced by heat stress. Besides, expressions of the mitochondrial dynamics- and anti-apoptosis-related genes were decreased and those of pro-apoptosis-related genes were increased by heat stress. HS induced pathological changes of mitochondria and triggered apoptosis in chicken spleens. However, these adverse effects triggered by HS were remarkably alleviated in Polysaccharide of Atractylodes macrocephala Koidz + heat stress group. This study confirmed the protective effects of Polysaccharide of Atractylodes macrocephala Koidz on the chicken spleen against the heat stress and revealed its mechanism, which is that Polysaccharide of Atractylodes macrocephala Koidz could relieve the heat stress-induced immune dysfunction of chicken spleens via reducing oxidative stress, enhancing the mitochondria function and inhibiting apoptosis.

Abstract
There are many reports that dietary supplementation with plant polysaccharides in pigs might promote their growth, but little is known about the maternal effect of ginseng polysaccharides (GPS) on piglets' growth by dietary supplementation to pregnant and lactating sows. In the current study, the effects of dietary supplementation with GPS on the immunity of sows and growth of their piglets were investigated. Results showed no significant difference among the four groups in the total number of piglets, live piglets, weak piglets and birth weight of piglets, indicating the GPS-treatment has no adverse effect on reproduction. Furthermore, the weaning weight of the GPS-treated groups was higher than that of control group (P < 0.05); among them, the addition of 200 mg/kg dose has the best effect. Interestingly, GPS increased the total immunoglobulin G concentration in milk and serum of sows (P < 0.05). The concentrations of interleukin (IL)-2, IL-6, tumor necrosis factor (TNF)-α, and interferon-γ in milk and serum of sows were also increased in the experimental groups relative to the control (P < 0.05). Meanwhile, maternal supplementation of GPS significantly increased IL-2 and TNF-α concentration in the piglets' serum of the experimental groups relative to control (P < 0.05). GPS (200 mg/kg) significantly increased the glutathione peroxidase activity in milk and serum (P < 0.05), while the concentrations of malondialdehyde were significantly reduced (P < 0.05). The present results indicated that GPS supplementation during late pregnancy and lactation improved immunity-related bio-molecular levels in sow serum and milk, which may be further beneficial to piglet health and growth through biological transmission effects.

The Effects of Agave fourcroydes Powder as a Dietary Supplement on Growth Performance, Gut Morphology, Concentration of IgG, and Hematology Parameters in Broiler Rabbits. BIOMED RESEARCH INTERNATIONAL 2016; 2016:3414319.

Abstract
This study was conducted to determine the effects of Agave fourcroydes powder as a dietary supplement on the growth performance, gut morphology, serum concentration of IgG, and the hematology parameters of broiler rabbits. A total of 32 rabbits [New Zealand × Californian] were weaned at 35 days. They were randomly selected for two dietary treatments (eight repetitions per treatment), which consisted of a basal diet and a basal diet supplemented with 1.5% dried-stem powder of A. fourcroydes. On day 60 from the initiation of treatment, gut histomorphology (duodenum and cecum), serum concentration of IgG, and hematology parameters were all measured. The results showed that A. fourcroydes powder supplementation improved (P < 0.05) the ADFI, ADG, and final BW. Correspondingly, this treatment increased (P < 0.05) the muscle and mucosa thickness and height and width of villi. However, duodenum crypts depth was lower (P < 0.05) when rabbits were fed with this natural product, compared with the basal diet treatment. Results also indicated that the A. fourcroydes powder increased (P < 0.05) the serum concentration of IgG but did not change the hematology parameters. This data indicates that A. fourcroydes powder, as a supplement, had beneficial effects on increasing the growth performance and serum concentration of IgG, as well as improving the gut morphology without affecting the hematology parameters in broiler rabbits.

Abstract
The aim of the present study was to investigate the effect of acute heat stress (HS) on the chicken immune response and to examine the role of selenium (Se) and the polysaccharides of Atractylodes macrocephala Koidz (PAMK) in immune regulation in the chicken immune system. Two hundred chickens were randomly divided into two groups: the HS group and the control (Con) group. These chickens were treated with Se (0.3 mg/kg), PAMK (200 mg/kg) alone, and a combination of Se (0.3 mg/kg) and PAMK (200 mg/kg). The cytokines; antioxidative enzymes; and HSP60, HSP70, and HSP90 levels were examined in chicken immune organs. The results indicated that HS-induced immune dysfunction included increased levels of TNF-α, IFN-γ, IL-2, IL-4, HSP60, HSP70, HSP90, and malondialdehyde (MDA) as well as decreased levels of glutathione peroxidase (GPx) and superoxide dismutase (SOD) in immune organs (P < 0.05). Among the affected organs, the bursa of Fabricius was one primary target of HS. The immune dysfunction induced by HS was alleviated (P < 0.05 or not) by treatment with Se and PAMK in different immune organs. However, Se only regulated the expression of TNF-α and IFN-γ, and PAMK influenced more cytokines in immune organs. The results showed that Se specifically regulated the TNF-α and IFN-γ pathways. Therefore, Se and PAMK played different roles in improving the immune response in HS chicken.

Abstract
The aim of the present study was to investigate the effect of selenium (Se), polysaccharide of Atractylodes macrocephala Koidz. (PAMK), and the combination of Se and PAMK on the immune response, heat shock protein (HSP) levels under heat stress (HS) condition in chicken spleen. Two hundred chickens were randomly divided into two groups, the HS group and the control (Con) group. Then these chickens were treated with Se (0.3 mg/kg), PAMK (200 mg/kg) alone, and the combination of Se (0.3 mg/kg) and PAMK (200 mg/kg). The antioxidative enzymes, cytokines contents, and expression levels of HSP27 and HSP70 were examined in chicken spleen. The results indicated that HS induced higher levels of TNF-α, IL-4, HSP27, HSP70, and MDA levels but lower level of IFN-γ, IL-2, Gpx, and SOD in spleen (P < 0.05). These responses were ameliorated by the treatment of Se, PAMK alone, and the combination of Se and PAMK (P < 0.05 or not) The results showed that under common condition, Se and PAMK could improve the immune response by enhancing the levels of some cytokines to proper levels; however, under HS condition, Se and PAMK could change the abnormal levels of cytokines and oxidative damages to ameliorate the injury induced by HS. In addition, there existed synergistic effect on the modulation of these biomarkers in chicken spleen between Se and PAMK. So both Se and PAMK play important roles in regulating the immune function in chicken. Considering the synergistic effect on immune regulation of PAMK, this herb deserves further investigation to evaluate its role in improving the effect of traditional immune regulators.

Abstract
Gong, J., Yin, F., Hou, Y. and Yin, Y. 2014. Chinese herbs as alternatives to antibiotics in feed for swine and poultry production: Potential and challenges in application. Can. J. Anim. Sci. 94: 223–241. Traditional Chinese medicine (TCM) has a long history of clinical practice, and its own theoretical framework focused on functions at the whole-body level. However, due to cultural differences, TCM has not been fully recognized in Western countries. With the recent development of the theory of whole-body systems biology and “-omics”, there is a new opportunity to study TCM and to close the gap between TCM and Western medicine, because of the similarity in the theoretical foundations between TCM and whole-body systems biology. The uniqueness of TCM theory and practice is the approach to maintain and restore the body balance as a whole with no or little unfavourable side effects. Recent studies have also shown that Chinese herbs used as feed additives can modulate nutritional metabolism, immune responses, and intestinal health of food-producing animals, demonstrating good potential as substitutes for dietary antibiotics. Nonetheless, some issues need to be addressed before Chinese herbs can reach their full application. This article has critically reviewed recent progresses in scientific research of Chinese herbs as feed additives and their potential to replace dietary antibiotics. Possible challenges in future application for swine and poultry production are also discussed.
