甘露寡糖-唾液乳杆菌对黄羽肉鸡生长性能、免疫器官发育、肠道形态和血清生化指标的影响
Effects of mannan oligosaccharides and Lactobacillus salivarius on growth performance,immune organ development,intestinal morphology,and serum biochemical indicators of yellow-feathered broilers
摘要
Abstract
The experiment aimed to investigate the effects of combined use of mannan oligosaccharides and Lactobacillus salivarius on the growth performance,immune organ development,intestinal morphology,and serum biochemical indicators of yellow-feathered broilers.A total of 360 one-day-old healthy yellow-feathered broiler chicks with uniform body weight were randomly divided into four groups,with three replicates per group and 30 chickens per replicate.The control group(CON group)was fed a basal diet,the mannan oligosaccharide group(MOS group)was supplemented with 0.3％mannan oligosaccharides,the Lactobacillus salivarius group(SAL group)was supplemented with 0.8％Lactobacillus salivarius,and the combined group(MOS+SAL group)was supplemented with 0.3％mannan oligosaccharides and 0.8％Lactobacillus salivarius.The experimental period lasted for 63 days.The results showed that compared with the CON group,the average daily gain and average daily feed intake of the SAL group and MOS+SAL group were significantly increased from 43 to 63 days(P＜0.05).On the 63rd day,the body weight was significantly increased(P＜0.05).The spleen index and bursa of Fabricius index in the MOS group and MOS+SAL group were significantly increased(P＜0.05).The villus height of the duodenum in the SAL group and MOS+SAL group was significantly increased(P＜0.05),and the villus height to crypt depth ratio in the MOS+SAL group was significantly increased(P＜0.05).The ileal villus height in the MOS group and MOS+SAL group was significantly increased(P＜0.05).Compared with the CON group,the concentrations of serum total protein and albumin in the SAL group and MOS+SAL group were significantly increased(P＜0.05),and the activity of alkaline phosphatase was extremely increased(P＜0.01).The study indicates that feeding of Lactobacillus salivarius and mannan oligosaccharides to yellow-feathered broilers is beneficial for improving growth performance,promoting healthy development of the intestine,and enhancing the development level of spleen and bursa of fabricius,with the combined feeding effect being better than separate feeding.关键词
