日粮添加副干酪乳杆菌XLK401对南丹瑶鸡生长性能、抗氧化和消化性能及免疫指标的影响
The effects of dietary supplementation with Lactobacillus paracasei XLK401 on growth performance,antioxidant and digestive abilities,and immune indicators in Nandan Yao chickens
摘要
Abstract
This experiment aimed to investigate the effects of Lactobacillus paracasei XLK401 on the growth performance,antioxidant and digestive functions,and immune indices of Nandan Yao chickens.A total of 180 Nandan Yao chickens were randomly divided into 4 groups,with 3 replicates per group and 15 chickens per replicate.The control group(CHE group)was fed a basal diet;the low-concentration Lactobacillus paracasei group(FGL6 group)was fed a diet supplemented with 1.0×106 CFU/mL of Lactobacillus paracasei;the high-concentration Lactobacillus paracasei group(FGL7 group)was fed a diet supplemented with 1.0×107 CFU/mL of Lactobacillus paracasei;and the chlortetracycline group(CKB group)was fed a diet supplemented with 1 mg/g of chlortetracycline.The trial lasted for 21 days.The results showed that compared with the CHE group,the final body weights of the FGL6 and FGL7 groups increased by 30.18%and 29.83%,respectively(P<0.001).There were no significant differences in immune organ indices among the groups(P>0.05).In terms of antioxidant performance,the superoxide dismutase(SOD)content increased by 204.70%and 210.04%(P<0.001),the glutathione peroxidase(GSH-PX)content increased by 67.24%and 165.52%(P<0.01),and the total antioxidant capacity(T-AOC)increased by 60.87%and 63.04%(P<0.001),while the malondialdehyde(MDA)content decreased by 69.85%and 38.75%(P<0.001).Regarding digestive performance,the α-amylase content increased by 81.17%and 112.97%(P<0.01),and the lipase content increased by 180.76%in the FGL6 group(P<0.001)but decreased by 21.16%in the FGL7 group(P>0.05).For immune indices,the interleukin-1β(IL-1β)content decreased by 13.21%and 20.56%(P<0.05),the interleukin-6(IL-6)content decreased by 20.00%and 24.89%(P<0.05),and the serum immunoglobulin G(IgG)content decreased by 15.62%and 12.65%(P>0.05).The study demonstrated that Lactobacillus paracasei XLK401 could enhance the immune function of Nandan Yao chickens.Under the conditions of this experiment,the optimal supplementation concentration of Lactobacillus paracasei was 1.0×106 CFU/mL.关键词
