饲粮精氨酸水平对肉鸡生长性能、免疫功能及小肠发育的影响
Effects of dietary arginine level on growth performance,immune function,and small intestine development of broilers
摘要
Abstract
The purpose of this experiment was to study the effects of dietary arginine level on the growth performance,immune function,and small intestine development of broilers.A total of 600 one-day-old male Arbor Acres broilers were randomly divided into five groups with six replicates in each group and 20 chickens in each replicate.Each group was supplemented with 0,0.65％,1.15％,1.65％,and 2.15％arginine in the basal diet.The trial period was 42 days.The results showed that compared with the control group,the body weight and average daily gain(ADG)of broilers in the 0.65％supplementation group were significantly higher(P＜0.05),and the villus height/recess depth of duodenum and jejunum were significantly higher after 42 days of experiment(P＜0.05).Compared with the control group,the content of serum immune protein in the 2.15％supplementation group increased significantly on the 21st day(P＜0.05),and the index of bursa of fabricius increased significantly on the 42st day(P＜0.05).The study indicates that proper addition of 0.65％arginine in basal diet can increase the body weight,average daily gain,and promote the development of duodenum and jejunum in the later growth stage of broilers.High level of arginine(2.15％)can improve the level of serum immune protein and promote the development of small intestine.关键词
