Yin X, Wang P, Yan Z, Yang Q, Huang X, Gun S. Effects of Whole-Plant Corn Silage on Growth Performance, Serum Biochemical Indices, and Fecal Microorganisms in Hezuo Pigs. Animals (Basel) 2024; 14:662. [PMID: 38473045 DOI: 10.3390/ani14050662] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2024] [Revised: 02/05/2024] [Accepted: 02/16/2024] [Indexed: 03/14/2024] Open
Abstract
In this study, we investigated the effects of the dietary inclusion of different proportions of whole-plant corn silage on growth performance, serum biochemical indexes, and intestinal microorganisms in Hezuo pigs. Thirty-two two-month-old Hezuo pigs (body weight: 7.88 ± 0.81 kg) were randomly divided into four groups of eight pigs (half male, half female) each. The control (CON) group received a basal diet, while the three experimental groups were fed the basal diet, part of which had been replaced with 5%, 10%, and 15% whole-plant corn silage, respectively. The experiment lasted for 127 days, including 7 days of pre-testing and 120 days of formal testing. At the end of the experiment, blood and fecal samples were collected. Compared with the CON group, the feed-to-gain ratio was significantly lower in the 10% test group (p < 0.05), whereas the total protein, albumin, triglyceride, and glucose contents were significantly higher (p < 0.05). No significant differences in total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, creatinine, urea, aspartate aminotransferase, and alanine aminotransferase were observed among the groups (p > 0.05). The addition of whole-plant corn silage to the diet significantly increased alpha diversity in the pig gut based on 16S rRNA gene sequencing. The principal coordinate analysis results showed significant clustering of the different groups (p < 0.05). At the phylum level, the addition of whole-plant corn silage to the diet significantly decreased (p < 0.05) the relative abundance of Firmicutes and significantly increased (p < 0.05) that of Bacteroidetes. At the genus level, the relative abundance of Streptococcus significantly decreased (p < 0.05) with increasing silage supplementation levels, whereas species diversity significantly increased (p < 0.05). In conclusion, 10% is the recommended inclusion ratio for whole-plant corn silage in the diets of pigs.

Trop Anim Health Prod 2023; 55:396. [PMID: 37930486 DOI: 10.1007/s11250-023-03802-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Accepted: 10/17/2023] [Indexed: 11/07/2023]
Abstract
The study aimed to evaluate the effects of Moringa oleifera leaf meal (MOLM) supplementation on nutrient utilization, milk yield, and reproductive performance of early lactating Sahiwal cows. Control cows (GC) received a basal diet, while the treatment cows (GM) were supplemented with concentrate comprising 12% MOLM. Ovarian activity and uterine involution were monitored by trans-rectal ultrasonography on the 21st, 28th, 35th, and 42nd days postpartum. The result indicated that MOLM-supplemented cows required fewer days (P ≤ 0.05) to complete uterine involution. As lactation progresses, there was a significant reduction (P ≤ 0.05) in the diameter of the cervix and uterine horns in GM than GC. There was a significant increase in the number of follicles on the 21st day and average milk yield in GM than GC. The incidence of endometritis and cystic ovarian disease was less in MOLM supplemented group. The use of MOLM in the diet reduced the total cost per cow per successful service. It is concluded that MOLM can be safely included at 12% in the diet of early lactating cows to modulate the reproductive performances of dairy cows. Dairy farmers can use moringa leaf meal to feed their dairy cows, which is cheaper and improves production and reproduction performance.

Abstract
The purpose of this research was to evaluate effects of grape seed extract (Gse) supplementation on the growth performance; ruminal fermentation; nutrient digestibility; and serum biochemical, antioxidative, and immune parameters of weaned beef calves. A total of 30 Simmental crossbred male calves with similar age and body weight were randomly allocated to two groups: a control group with no Gse (CON) and a Gse supplementation group (GSE) (4 g/d Gse per animal). The results show that, compared with the CON group, the average daily gain significantly increased (p = 0.043) in the GSE group. The ruminal contents of microbial protein and butyrate in GSE group were higher (p < 0.05) than those in the CON group. Additionally, calves fed Gse displayed increased (p < 0.05) dry matter and neutral detergent fiber digestibility. Moreover, the serum concentrations of triglyceride, catalase, superoxide dismutase, immunoglobulin G and immunoglobulin M were higher (p < 0.05) in the GSE group than those in the CON group. However, opposite tendencies of non-esterified fatty acid, malondialdehyde, tumor necrosis factor-α and interleukin-6 were found between the two groups. Overall, the supplementation of Gse can improve ruminal fermentation, nutrient digestibility, antioxidant ability, and immunity, as well as promoting the healthy growth of weaned cross-breed beef calves.

Abstract
The development of different innovative feed resources for livestock is important to provide the essential nutrients and diminish the emission of greenhouse gases. The purpose of the present experiment was to study the response of replacing concentrate with Moringa oleifera leaves in terms of the nutrient intake, digestibility, enteric methane emissions, and performance of goat kids with a berseem-fodder-based diet under different roughage (R)-to-concentrate (C) ratios. Twenty-four goat kids (3 months of age) were distributed into four groups of six animals each, using a randomized block design (RBD). Kids of Group I (control) were fed a basal diet with 70R:30C without any tree leaf supplementation. Group II kids were fed with 60R:40C, where 10% of the concentrate mix was replaced with Moringa leaf (ML powder). In Group III, kids were fed with 70R:30C with 20% ML replacement. In Group IV, kids were fed with 80R:20C with 20% ML replacement. A metabolic trial was conducted after 180 days of feeding to assess the impact of ML on blood metabolites, antioxidant status, immunity parameters, and enteric methane emissions. The results revealed that dry matter digestibility, organic matter, and NDF were better (p < 0.05) in ML-treated kids (GII and GIII) compared to GI. Feed conversion and average daily gain were also enhanced (p < 0.05) in the treated groups as compared to controls. Total blood protein and albumin were increased in GII and GIII kids compared to GI. Plasma cholesterol levels were decreased (p < 0.001) in GII, GIII, and GIV as compared to GI. Glutathione peroxidase, catalase, and superoxide dismutase enzyme activities were also enhanced in GII, GIII, and GIV compared to controls. ML supplementation improved cell-mediated immunity and humoral immunity responses in goat kids. Enteric methane emissions decreased in the treated groups as compared to the controls. Moringa oleifera leaf may be used up to the level of 10−20% in concentrate mixes to improve digestibility, blood biochemical parameters, immunity status, and antioxidant activity in goat kids. Supplementation of ML not only enhanced the digestion and health of goat kids, but also decreased their methane emissions.

Cultivation and Uses of Moringa oleifera as Non-Conventional Feed Stuff in Livestock Production: A Review. LIFE (BASEL, SWITZERLAND) 2022; 13:life13010063. [PMID: 36676012 PMCID: PMC9865686 DOI: 10.3390/life13010063] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Revised: 12/18/2022] [Accepted: 12/21/2022] [Indexed: 12/28/2022]
Abstract
M. oleifera is the best known and the most utilized of the 14 known species of the genus Moringa. Moringa is used as animal fodder and a medicinal plant as well as in the purification of water. Studies have shown that the day/night temperature of 30/20 °C is the most favorable for M. oleifera germination, plant growth and development. M. oleifera plants prefer sandy, well-drained loam soils due to their susceptibility to waterlogged soil conditions. It is recommended to use fertilizers to improve plant growth and the amount of forage production in areas with low rainfall and extreme temperatures. For forage production, an area of 20 × 20 cm is adapted to 16,000 plants per hectare. Chemical analyses confirmed the presence of different groups of pharmacologically active chemical compounds, as well as functional compounds of nutritional value such as carbohydrates, proteins, fats and vitamins, in M. oleifera. The reviewed literature particularly encourages the use of M. oleifera whole plants as nonconventional forage in ruminants' nutrition, as well as using M. oleifera leaves or leaves extract as a protein source for broilers and laying hens. M. oleifera in livestock feed with the ultimate goal of producing functional food (meat, eggs and milk) with appropriate contents of human health-promoting substances such as omega-3 and organic selenium remains to be elucidated. Furthermore, M. oleifera inclusion in livestock feed has the potential to increase the shelf-life of animal products during storage and processing. Further research is needed to determine the appropriate supplementation level of different plant parts or their extracts, as well as the appropriate processing methods or treatments of M. oleifera, in order to improve its palatability and consequently enhance the production performance of livestock without compromising animal health.

Abstract
Although chemical additives are able to improve the efficiency of ruminal fermentation, they can leave residues in the meat. However, a blend of secondary metabolites can improve ruminal fermentation without harming the population welfare. Five levels (0.0, 1.5, 3.0, 4.5, and 6.0 g/day) of a blend of secondary metabolites from mesquite extract in sheep feed to promote increases in the nutritional value, ruminal parameters, nitrogen (N) use efficiency, microbial protein (MP) synthesis, and blood metabolites. Ten intact male Santa Inês sheep with average body weight of 55 ± 9.81 kg were used in a 5 × 5 Latin square design, replicated twice. There was a quadratic response of the digestibility of dry matter (DM), organic matter (OM), crude protein (CP), and total digestible nutrients (TDN). Microbial protein concentrations, MP synthesis efficiency, propionic acid levels, and acetic/propionic acid ratio also showed a quadratic response. The blend promoted a quadratic effect on plasma glucose and lactate levels. On the other hand, it decreased the concentrations of ammoniacal nitrogen, plasma urea, and plasma cholesterol. It is recommended to supply a blend of secondary metabolites at 3.43 g/day.

Abstract
The structure and types of rumen microbes are closely related to host health. This study aimed to evaluate the effect of Broussonetia papyrifera silage (BPS) gradually replacing the whole crop maize silage (WCMS) on total tract digestibility, rumen fermentation parameters, serum biochemical indicators, and rumen microbes of Holstein heifers. The diet treatment consisted of four proportions of BPS (0%, 25%, 50% and 75%) as substitute for WCMS (designated as T0, T25, T50 and T75, respectively). Twenty heifers (body weight = 245 ± 24 kg) were randomly divided into four groups of five heifers, and randomly received one diet. The feeding adaption period was 7 days, and the experiment period was 30 days. Our findings suggested that the digestibility of neutral detergent fiber and crude protein increased linearly with the increased in BPS (P < 0.05). The concentrations of total protein and albumin increased quadratically with the increased in BPS (P < 0.05). The 16s high-throughput sequencing showed that feeding BPS did not change the diversity and structure of the rumen microbes of heifers. However, the relative abundances of Tenericutes and SR1-Absconditabacteria increased linearly with the increased in BPS (P < 0.05). The Weighted Correlation Network Analysis results suggested that ALT concentration was positively correlated with the abundance of Prevotella-1 (r = 0.73; P = 0.007). In general, Holstein heifers fed with BPS did not change the diversity and uniformity of rumen microbes, and enhanced the body protein metabolism.

Abstract
The purpose of the current study was to explore the supplementing effects of Moringa oleifera leaf powder (MOLP) on plasma and milk biochemical indices and productive/reproductive performance of goats. A total of 30 healthy pregnant goats were randomly distributed (n = 10) into three experimental groups: control (M0) group (basal diet without MOLP), M2% group (basal diet + 2% MOLP), and M3.5% group (basal diet + 3.5% MOLP). The experiment started 2 months before parturition and continued till the first month of lactation. The plasma flavonoids were significantly increased in the M3.5% group during the entire experiment, whereas the total phenolic contents were enhanced only during the lactation period depending on the supplementation percentage. The amount of vitamin C increased significantly in M2% and M3.5% groups as compared to the M0 group. Supplementation of MOLP improved the plasma total antioxidant capacity by declining malondialdehyde concentration and total oxidant status values. The activities of superoxide dismutase and peroxidase enzymes were modified in M2% and M3.5% supplemented groups throughout the experiment, while the catalase activity was significantly influenced only during the lactation stage. The protein and lycopene contents in plasma were significantly improved in the M3.5% group, whereas the total sugars and carotenoid level was increased in both M2% and M3.5% groups. Dietary supplementation with 3.5% MOLP more effectively enhanced protease and amylase activities as compared to 2% supplementation. MOLP also improved the biochemical indices and antioxidant status of colostrum and milk. The milk yield, weight gain of the kids, and reproductive performance were high in M2% and M3.5% groups in comparison to the M0 group. These findings disclose that supplementing the diet with 3.5% MOLP improves antioxidant status, milk yield, and reproductive performance in goats.

Abstract
The objective of this experiment was to investigate the potential benefits of active dry yeast (ADY) on the growth performance, rumen fermentation, nutrient digestibility, and serum parameters of weaned beef calves. Thirty Simmental crossbred male calves (body weight = 86.47 ± 4.41 kg and 70 ± 4 d of age) were randomly divided into 2 groups: control (CON) (fed basal ration) and ADY (fed basal ration and 5 g/d ADY per calf). The dietary concentrate-to-roughage ratio was 35:65. All the calves were regularly provided rations 3 times a day at 07:00, 13:00, and 19:00 and had free access to water. The experiment lasted for 60 d. The average daily gain of ADY group was higher (P = 0.007) than that of the CON group, and the ratio of feed intake to average daily gain in the ADY group was reduced (P = 0.022) as compared to the CON group. The concentration of ruminal ammonia-N was higher (P = 0.023) in the CON group than that in the ADY group, but an opposite trend of microbial protein was found between the 2 groups. Also, the ruminal concentrations of propionate and butyrate were higher (P < 0.05) in the ADY group than those in the CON group. Calves fed ADY exhibited higher (P < 0.05) crude protein and neutral detergent fiber digestibility. Supplementation of ADY increased (P < 0.05) the contents of glucose, glutathione peroxidase, superoxide dismutase, immunoglobulin A, immunoglobulin M, and interleukin 10 in the serum of calves, but an opposite trend was observed in malondialdehyde, interleukin 1 beta, and tumor necrosis factor alpha contents between the 2 groups. In conclusion, dietary supplementation with ADY could improve the growth performance, rumen fermentation, nutrient digestibility, antioxidant ability, and immune response of weaned beef calves.

Abstract
The study was conducted to investigate nutrient metabolism and semen quality of bulls fed with moringa (Moringa oleifera) leaves, twigs, and branches as a major concentrate ingredient. Twenty-one Red Chittagong bulls of about 204 (±50) kg initial live weight (LW) were randomly divided into three equal LW groups. They were fed maize silage as a basal feedstuff for 65 days with the supplementation of concentrate mixtures at 1% of LW, consisting of either 0, 25, or 50% moringa mash on a fresh basis. Moringa mash was a sun-dried ground preparation of leaves, twigs, and branches of moringa. The results indicated that different levels of moringa in concentrate mixtures (0, 25, and 50%) did not change daily DM intake, digestibility, and LW gain of bulls (p > 0.05). However, increasing dietary moringa (up to 203 g/kg DM) significantly decreased production cost of methane (CH4) (methane emission [kg/kg gain] = 1.6422—[0.0059 × moringa intake, g/kg DM], n = 12, R2 = 0.384, P = 0.032) in a similar metabolizable energy intake level (0.21 ± 0.01 MJ/kg LW). Also, higher dietary moringa significantly reduced urinary nitrogen loss (urinary nitrogen [% digested nitrogen] = 43.0 – 0.069 × moringa intake [g/kg DM]; R2 = 0.3712, P = 0.034). Thus, increasing moringa by 1 g/kg DM decreased CH4 emission by 6 g/kg gain and absorbed nitrogen loss by 0.069 %. Also, progressive motility of sperm increased significantly (33.0, 51.0, and 60.1%, respectively; p = 0.03) in bulls fed with concentrate mixtures containing moringa at 0, 25, or 50%. It may be concluded that feeding moringa mash at 203 g/kg DM may decrease energy loss as methane and urinary nitrogen loss without impacting the production of beef cattle. Feeding moringa mash to beef cattle may abate dietary energy and nitrogen loss and consequently decrease the environmental pollution.

Abstract
The drumstick tree is a fast-growing multipurpose tree with a large biomass and high nutritional value. However, it has rarely been exploited as a protein source. This study investigated solid-state fermentation induced by Aspergillus niger, Candida utilis and Bacillus subtilis to obtain high-quality protein feed from drumstick leaf flour. The results showed that fermentation induced significant changes in the nutritional composition of drumstick leaf flour. The concentrations of crude protein, small peptides and amino acids increased significantly after fermentation. The protein profile was also affected by the fermentation process. Macromolecular proteins in drumstick leaf flour were degraded, whereas other high molecular weight proteins were increased. However, the concentrations of crude fat, fiber, total sugar and reducing sugar were decreased, as were the anti-nutritional factors tannins, phytic acid and glucosinolates. After 24 h fermentation, the concentrations of total phenolics and flavonoids were increased. The antioxidant capacity was also significantly enhanced.

Abdel-Raheem SM, Hassan EH. Effects of dietary inclusion of Moringa oleifera leaf meal on nutrient digestibility, rumen fermentation, ruminal enzyme activities and growth performance of buffalo calves. Saudi J Biol Sci 2021; 28:4430-4436. [PMID: 34354427 PMCID: PMC8324938 DOI: 10.1016/j.sjbs.2021.04.037] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Revised: 04/12/2021] [Accepted: 04/13/2021] [Indexed: 11/06/2022] Open
Abstract
This study was conducted to investigate the impact of dietary inclusion of Moringa oleifera leaf meal (MLM) as a substitution for soybean meal on nutrient digestibility, rumen fermentation, rumen enzyme activity, blood metabolites, growth-related hormones, and growth performance of buffalo calves. Thirty buffalo calves eight to nine months of age with an average body weight of approximately 153.7 ± 0.97 kg were randomly distributed through three dietary treatments (ten calves/treatment). MLM inclusion rates were 15% (M15) and 20% (M20), replacing soybean meal by 50 and 75% in the concentrate mixture, respectively. The results indicated that, digestibility of dry matter, organic matter (OM), and crude fiber (CF) increased significantly (p < 0.05) with MLM inclusion, while the digestibility of crude protein (CP) and ether extract (EE) reduced significantly (p < 0.05) with MLM addition. Dietary supplementation with MLM significantly affected (p < 0.001) rumen fermentation by reducing ruminal enzymes, ruminal ammonia-N, total protozoa, and acetate/propionate ratio and increasing acetic, propionic, and butyric acids and total volatile fatty acid concentrations (p < 0.001). Furthermore, dietary inclusion of 15% MLM significantly improved (p < 0.001) final body weight, dry matter intake of feed, daily weight gain, feed conversion efficiency, blood metabolites, and plasma insulin growth factor-I (IGF-I). It can be concluded that MLM is a multi-purpose protein supplement that provides some nutritional and therapeutic advantages when replacing 50% of soybean meal. Dietary supplementation of 15% MLM improved rumen fermentation, growth performance, blood metabolites, plasma IGF-I and mitigated ammonia and methane without any adverse effects in growing buffalo calves.

Abstract
OBJECTIVE This experiment was designed to assess the quality and to evaluate the feeding impact of moringa feed on intake, digestibility, rumen fermentation, methane (CH4) production, and milk yield. MATERIALS AND METHODS According to body weight and exit-entry average daily milk production, fifteen BLRI cattle breed-1 lactating cows of 3rd or 4th stage of parturition with wk 3 and 4 of calving were selected and were equally and randomly distributed into three dietary groups. One group of cows was fed a control diet (T0) consisting of 1:1 dry matter (DM) of Napier silage and conventionally mixed concentrate. The other two groups were fed a control diet by randomly replacing i) 50% (T1) or ii) 100% (T2) of its concentrate with moringa feed. The three dietary groups were balanced nutritionally based on energy and protein following the Bangladesh Standards and Testing Institution (BSTI) standard. RESULTS The concentrate mixture was replaced with moringa feed to increase the feed efficiency and to reduce the DM or crude protein intake (p < 0.05) per 100 kg of metabolic body weight. The T2 group flourished with the highest (p < 0.05) amount of raw milk and also 4% fat-corrected milk (4.39 and 4.59 kg/day, respectively) compared to the T0 group (3.30 and 3.49 kg/day, respectively). However, it increased (p < 0.05) the concentration of total volatile fatty acid and decreased (p < 0.05) the blood and milk cholesterol, and ammonia-nitrogen (NH3-N) was reputed by adding moringa feed into the T0 group, without showing any significant (p > 0.05) change in CH4 production, fat, solid not fat, lactose or protein content of milk. CONCLUSION Therefore, moringa feed increased the productivity in dairy cows, replacing the whole concentrate diet.

Effects of Fermented Herbal Tea Residues on the Intestinal Microbiota Characteristics of Holstein Heifers Under Heat Stress. Front Microbiol 2020; 11:1014. [PMID: 32528442 PMCID: PMC7264259 DOI: 10.3389/fmicb.2020.01014] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2019] [Accepted: 04/24/2020] [Indexed: 01/01/2023] Open
Abstract
Herbal tea residue (HTR) is a reusable resource with high nutritional value and bioactive substances content, which can be used as a feed additive. In the present study, HTRs were fermented by lactic acid bacteria, and then fed to a total of 90 Holstein heifers, termed as CN, LC, and HC groups. The supplementation improved physiological indices of respiratory frequency and rectal temperature, increased the concentrations of immunoglobulins and antioxidant capacity-related parameters, and reduced the concentrations of heat stress-related parameters and serum hormones. The heifers’ body height increased considerably, while their energy metabolism rates were stimulated in response to fermented HTRs. We also studied the fecal microbial community composition of 8 Holstein heifers in each group, and employed correlation analysis with tested parameters. We found that the bacteria were closely related to characteristics including the energy utilization rate, growth performance, serum biochemical indexes, and fecal SCFA levels of the heifers. Based on our findings, the 5% fermented HTRs replaced corn silage might be advantageous for the heifers’ characteristics under heat stress.

Abstract
The aim of the current research was to investigate the effects of betaine (Bet) supplementation on the production performance, rumen fermentation, digestibility, and serum indexes of dairy cows. Thirty healthy Holstein cows with the same parity (milk production = 22 ± 2.5 kg) were randomly selected and divided into three groups. One group served as a control group (CON; no betaine); the other two groups were Bet1 (15 g/d per cow) and Bet2 (30 g/d per cow). All cows were fed regularly three times a day at 06:00, 14:00, and 22:00 h. Cows received the formulate diet, and water was provided ad libitum. The experiment lasted for 60 days during the summer season. Results showed that the dry matter intake, milk protein, and fat of Bet1 cows was significantly higher (p < 0.05) than that in other groups. The content of volatile fatty acid (VFA) in Bet1 was significantly higher (p < 0.05) than CON. Consistent with VFA, a similar trend was found in acetate, while propionate exhibited an opposite trend. Compared to other groups, the microbial protein (MCP) concentrations of Bet1 increased (p < 0.05). The apparent digestibility of dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), and acid detergent fiber (ADF) of Bet1 was significantly higher (p < 0.05) than CON. The serum concentration of total antioxygenic capacity (T-AOC) in Bet1 and Bet2 was significantly increased (p < 0.05). Furthermore, the contents of malonaldehyde (MDA) and superoxide dismutase (SOD) in Bet2 were higher (p < 0.05) than that in other groups. Compared to CON and Bet2, Bet1 significantly increased (p < 0.05) the serum concentrations of glucose. Therefore, it is practicable to feed betaine to lactating cows to improve their performance in heat stress.

Abstract
The increased consumption of livestock, poultry, and fish products in people's diet threatens to drive production toward the use of more and more conventional crops in animal feeds. In this context, alleviating the tightening grain crop supply and ensuring the healthy development of animal husbandry through innovations in protein feedstuff production remain considerable challenges. Moringa oleifera is a miracle tree species with abundant nutrients, high protein biological value, and good feeding effect. As a new protein feedstuff, M. oleifera has great potential in alleviating the feeding crisis. Here, we review available literature regarding the characterization of M. oleifera in the field of animal husbandry in terms of nutrient content, digestion, and absorption characteristics, and feeding effects and present current challenges in using M. oleifera as animal feed.

Abstract
Bovine mastitis is a common inflammatory disease in the udder of dairy cows that causes economic loss to dairy industries. The development of alternative strategies, especially the utilization of natural products, e.g. Moringa oleifera, has gained a lot of interests. The objective of the current study was to investigate the protective effects of moringa extract (ME) in bovine mammary epithelial cells (MAC-T) in in vitro settings. Radical scavenging capacities and anti-inflammatory properties of ME were examined using lipopolysaccharide (LPS)-challenged MAC-T cells. ME showed significant radical scavenging activities. In addition, ME decreased reactive oxygen species produced by LPS in cells. ME also attenuated inflammatory cyclooxygenase-2 expression induced by LPS by down-regulating NF-κB signaling cascade. Moreover, ME ameliorated LPS-induced pro-inflammatory cytokines including tumor necrosis factor-, interleukin-1, and interleukin-6. Furthermore, ME up-regulated mRNA expression levels of heme oxygenase-1, NAD(P)H: quinone oxidoreductase-1, and thioredoxin reductase 1. Importantly, ME promoted differentiated MAC-T cells by increasing mRNA expression levels of α-casein S1, α-casein S2, and β-casein. In conclusion, ME has beneficial effects in bovine mammary epithelial cells through its anti-inflammatory, antioxidant, and casein production properties. Our study provides evidence that ME could be a good candidate for a feed supplement to decrease inflammatory responses due to bovine mastitis.

Effect of Dietary Supplementation of Moringa Oleifera on the Production Performance and Fecal Methanogenic Community of Lactating Dairy Cows. Animals (Basel) 2019; 9:ani9050262. [PMID: 31121857 PMCID: PMC6562924 DOI: 10.3390/ani9050262] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2019] [Revised: 05/09/2019] [Accepted: 05/20/2019] [Indexed: 11/18/2022] Open
Abstract
Simple Summary High-quality forages such as protein-rich ingredients are essential to maximize production performance in dairy production. However, enteric methane produced by methanogenesis represents a substantial waste of feed energy for ruminants. Thus, it is important to evaluate the environmental effect when such feed ingredients are used to provide necessary nutrients. The aim of the present study was to examine the effects of dietary supplementation of Moringa oleifera on the production performance and fecal methanogenic community in lactating cows. The study’s main results suggest that inclusion of Moringa oleifera improved milk fat content and changed the composition and diversity of methanogens. This study indicates that secondary metabolites from Moringa oleifera may regulate fermentation conditions and associations between some methanogens and other microbes. These findings provide basic information on the utilization of alternative forage resources for dairy cows and can help to better understand the regulation of microbial metabolic function and methane emissions. Abstract Development of alternative forage resources is of great importance to provide necessary nutrients and minimize greenhouse gas emissions in ruminant production. The aim of this study was to examine the effects of dietary supplementation of Moringa oleifera on the production performance and fecal methanogenic community in dairy cows using methyl-coenzyme M reductase α-subunit gene. Sixty-four cows were allocated to one of four treatments: basal diet without M. oleifera (control) or low (3% w/w, M3), medium (6%, M6), or high (9%, M9) supplementation with M. oleifera. This study demonstrated that different supplementation levels of Moringa oleifera in the diet achieved similar feed intake and milk production, but adding 6% of Moringa oleifera improved milk fat content. Two families, two phyla, three genera, and three species in total were identified among the four treatments. The fecal archaeal community in the control treatment was predominated by Methanobrevibacter (39.1% of the total sequence reads) followed by Methanosphaera and Methanocorpusculum at the genus level. The increased abundance of the Methanosphaera genus and Methanosphaera sp. ISO3-F5 species was induced by secondary metabolites of Moringa oleifera in the diet. Results indicated that Moringa oleifera supplementation not only improved dairy product quality but could also potentially reduce methane emissions.

Abstract
Chemical composition and rumen degradability of waste vinegar residue (WVR) as roughage feed used for mutton sheep were evaluated in this work. Compared with the unfermented WVR, the WVR fermented by N. sitophila had more (P < 0.01) ash, crude protein (CP), and true protein (TP), less (P < 0.01) ether extract (EE), and significantly more carotenoid by about 27 times. But the contents of dry matter (DM), crude fiber (CF), neutral detergent fiber (NDF), and acid detergent fiber (ADF) had no obvious differences (P > 0.05) between unfermented and fermented WVR. The results suggested that the nutritional value of fermented WVR was higher for mutton sheep as roughage feed than that of unfermented WVR. The effective degradability (ED) of DM was higher (P < 0.05) in sheep with fermented WVR-based diet. The ED of CP and NDF of fermented WVR was reduced (P < 0.01) compared with the unfermented WVR. The results further suggested that the fermentation improved the degradability of WVR, and the rumen degradability of protein by ruminal flora decreased in fermented WVR, saving more protein for the sheep post-ruminal digestion and absorption. Furthermore, the results presented here clearly indicated the potential of fermented WVR by N. sitophila as an unconventional and functional feedstuff with rich carotenoid for ruminants, which could reduce WVR discharge in vinegar brewing industry and improve ruminant production. This work laid a foundation for the development of ruminant carotenoid functional feed.
