Animals (Basel) 2024; 14:1628. [PMID: 38891675 PMCID: PMC11171317 DOI: 10.3390/ani14111628] [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: 04/19/2024] [Revised: 05/23/2024] [Accepted: 05/29/2024] [Indexed: 06/21/2024] Open
Abstract
A total of 320 1-day-old broilers were randomly divided into five groups. The control group (CON) received a basal diet, while the FAP4, FAP2, and FAP1 groups were provided with the basal diet supplemented with 4%, 2%, and 1% fermented Astragalus powder, respectively. The unfermented Astragalus powder (UAP2) group was fed the basal diet supplemented with 2% UAP. Each group contained eight replicates of eight chicks each. The results revealed that the final BW and ADG in the FAP 1 and FAP2 were higher than those in the UAP2 and CON groups, while reducing F/G from day 14 to day 42. On day 42, the thymus index in the UAP and FAP groups as well as the bursa index in the FAP4 group showed significant increases compared to those in the CON group. Supplementation with 2% FAP elevated serum IgA levels in broilers on day 28 and day 42, and it also increased serum IgG levels on day 42. Furthermore, supplementation with 2% FAP elevated serum albumin (ALB) levels in broilers, while supplementation with 4% FAP increased serum (glucose) GLU levels in broilers on day 28. The serum biochemical parameters and pathological observation of the liver and kidney in the groups did not show any adverse effects on broilers' health. In addition, the serum total antioxidant capacity (T-AOC) level significantly increased in the FAP4 and FAP2 groups on day 28, and the malondialdehyde (MDA) level in both serum and liver tissue decreased in the FAP2 group on day 28 and day 42. Compared to the CON group, 2% FAP and 2% UAP supplementation reduced the relative abundance of Bacteroides and supplementation with 2% FAP increased the relative abundance of Alistipes on day 42. In conclusion, the dietary supplementation of FAP can enhance the growth performance, immune function, and antioxidant capacity and regulate microflora in broilers, of which 2% FAP is more effective. It indicates FAP exhibits significant application potential as a promising feed additive for broilers.

Abstract
Introduction This study investigated the effects of storage japonica brown rice (SJBR) and bile acids (BA) on the growth performance, meat quality, and intestinal microbiota of growing-finishing Min pigs. Methods A total of 24 healthy Min pigs with a similar body weight of 42.25 ± 2.13 kg were randomly divided into three groups with eight replicates of one pig each. The groups were as follows: CON (50% corn), SJBR (25% corn +25% SJBR), and SJBR + BA (25% corn +25% SJBR +0.025% hyodeoxycholic acid). The experimental period lasted from day 90 (the end of the nursery phase) to day 210 (the end of the finishing phase). Results The results showed the following: (1) Compared with the CON group, there was no significant difference in the average daily gain (ADG) and average daily feed intake (ADFI) of the SJBR and SJBR + BA groups, and the feed conversion ratio (FCR) was significantly decreased (p < 0.05). (2) Compared with the CON group, the total protein (TP) content in the serum was significantly increased, and the blood urea nitrogen (BUN) content was significantly decreased (p < 0.05) in the SJBR and SJBR + BA groups; moreover, HDL-C was significantly higher by 35% (p < 0.05) in the SJBR + BA group. (3) There were no significant differences in carcass weight, carcass length, pH, drip loss, cooking loss, and shear force among the groups; the eye muscle area was significantly increased in the SJBR group compared with the CON group (p < 0.05); back fat thickness was significantly decreased in the SJBR + BA group compared with the SJBR group (p < 0.05); and the addition of SJBR significantly increased the mRNA expression of MyHC I in the longissimus dorsi (LD) muscle of growing-finishing Min pigs (p < 0.05). (4) The cecal bacteria were detected using 16S rDNA, and the proportion of Lactobacillus was increased gradually at the genus level, but there was no significant difference among the different groups. Conclusion In conclusion, 25% SJBR can improve the growth performance and increase the abundance of intestinal beneficial bacteria, and based on this, adding bile acids can reduce the back fat thickness of growing-finishing Min pigs.

Effects of dietary supplementation of fermented Artemisia argyi on growth performance, slaughter performance, and meat quality in broilers. Poult Sci 2024; 103:103545. [PMID: 38387294 PMCID: PMC10899031 DOI: 10.1016/j.psj.2024.103545] [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: 12/12/2023] [Revised: 01/28/2024] [Accepted: 02/06/2024] [Indexed: 02/24/2024] Open
Abstract
Artemisia argyi (AA) is promising as a potential feed additive. Microbial fermentation is beneficial to the degradation of cell walls and the better release of bioactive compounds of AA. However, there are few reports on the application of fermented AA as a feed additive for broilers. The present study intended to evaluate the application value of fermented AA as a feed additive for broilers by examining the effects of the dietary supplementation of Aspergillus niger-fermented AA and unfermented AA on growth performance, slaughter performance, and meat quality of brokers. A total of 360 newly hatched (1-day-old) broilers with similar body weight were randomly divided into the following 5 groups: basal diet group as control (C) group, basal diet +3% unfermented AA (E1) group, basal diet + 1% fermented AA (E2) group, basal diet + 3% fermented AA (E3) group, basal diet + 5% fermented AA (E4) group. Each group included 6 replicates with 12 broilers per replicate, and the feeding trail lasted for 48 d. Body weight and feed intake were recorded every 2 wk, and the feed gain ratio was calculated to assess growth performance. At 42 d, 6 broilers from each group were slaughtered, and the carcass traits were calculated. The results showed that compared with the control group, Aspergillus Niger could effectively destroy AA fiber, which contributed to better release of AA bioactive compounds. Moreover, dietary supplementation with AA could improve the growth performance of broilers (P < 0.05), and the effect of fermented AA was better than unfermented AA, especially 3% fermented AA. From 28 to 42 d, compared with the control group, the average daily gain of broilers in the group supplementation with 3% fermented AA was significantly increased (P < 0.05), and the feed-to-gain ratio was decreased (P < 0.05). At 42 d, the dressing percentage, half-eviscerated carcass percentage, eviscerated carcass percentage, and breast muscle percentage of broilers in the groups of 1, 3, and 5% fermented AA diets were significantly improved (P < 0.05), and the thigh muscle percentage of broilers in the group with 3% fermented AA diets was significantly improved (P < 0.05). Meanwhile, the meat quality of broilers in the group with fermented AA diets was also significantly improved. Birds in AA groups had higher a* value and lower shear force of breast muscle, especially the group supplementation with 3% fermented AA (P < 0.05). In conclusion, fermented AA has good application value as a potential feed additive for broilers, dietary supplementation of fermented AA can improve the production performance and meat quality of broiler chickens, of which 3% fermented AA is more effective.

Molecules 2023; 28:5498. [PMID: 37513370 PMCID: PMC10384955 DOI: 10.3390/molecules28145498] [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: 06/21/2023] [Revised: 07/09/2023] [Accepted: 07/14/2023] [Indexed: 07/30/2023] Open
Abstract
Polygonati Rhizoma is a widely used traditional Chinese medicine (TCM) with complex pre-processing steps. Fermentation is a common method for processing TCM to reduce herb toxicity and enhance their properties and/or produce new effects. Here, in this study, using Bacillus subtilis and Saccharomyces cerevisiae, we aimed to evaluate the potential application of solid fermentation in isolating different functional polysaccharides from Polygonatum cyrtonema Hua. With hot water extraction, ethanol precipitation, DEAE anion exchange chromatography and gel filtration, multiple neutral and acidic polysaccharides were obtained, showing different yields, content, compositions and functional groups after fermentation. Combining in vitro experiments and in vivo aging and immunosuppressed mouse models, we further compared the antioxidant and immunomodulating bioactivities of these polysaccharides and found a prominent role of a natural polysaccharide (BNP) from fermented P. cyrtonema via Bacillus subtilis in regulating intestinal antioxidant defense and immune function, which may be a consequence of the ability of BNP to modulate the homeostasis of gut microbiota. Thus, this work provides evidence for the further development and utilization of P. cyrtonema with fermentation, and reveals the potential values of BNP in the treatment of intestinal disorders.
