摘要
选取 190日龄的产蛋黑凤鸡 135只 ,随机分成 5组。对照组饲喂基础日粮 ,其余 4组分别以 0 .5 %和 0 .3%的小肽制剂添加量替代基础日粮中 30 %或 5 0 %的鱼粉量。结果表明 ,添加量为 0 .5 %的小肽制剂替代基础日粮中 30 %的鱼粉量的试验 1组黑凤鸡的采食量、产蛋性能蛋的品质、饲料利用率均较高 ;小肽添加量为 0 .5 %的试验 1组和 2组黑凤鸡血清BUN水平分别比对照组低 33.33% (P >0 .0 5 )和 7.84 % (P >0 .0 5 ) ,TP含量比对照组分别高 14 .2 4 % (P <0 .0 5 )和 5 .2 2 % (P >0 .0 5 ) 。
black boned chickens with black feather were selected, and allotted randomly to five groups in 190d. The basal diet contain 2.5% fishmeal, the rest four diets plus 0.3% or 0.5% small peptide replace 30% or 50% fishmeal in the basal diet respectively. The result show that the diet contain 0.5% small peptide (replace 30%fishmeal) is most effective, such as intake, laying performance, egg quality and feed efficiency increased. Serum BUN level decreased 33.33%(P>0.05) and 7.84%(p>0.05) in two diets that contain 0.5% small peptide (replaced 30% and 50% fishmeal) to the basal diet, and TP concentration increased 14.24%(P<0.05) and 5.22%(P>0.05) respectively.
