小肽制品对黄羽肉鸡生长性能及血液生化指标的影响

为了研究小肽制品对黄羽肉鸡生长性能及血液生化指标的影响，选择健康1日龄快大型黄羽肉雏鸡64只，随机分成A和B组，每组4个重复，每重复8只，其中A组饲喂日粮Ⅰ（含5%鱼粉），B组饲喂日粮Ⅱ（含2%鱼粉），其中日粮Ⅱ添加0.5%小肽制品，试验期8周。试验结果表明，在黄羽肉鸡日粮中用少量的小肽制品取代一定量的鱼粉，降低日粮中蛋白质含量还能使黄羽肉鸡有较高的生长性能，并可显著提高2周龄时的血清总蛋白和白蛋白的含量和显著降低2周龄时的血清总胆固醇的含量（P<0.05）。

Effect of Small Peptides on Growth Performance and Biochemical Parameters of the Yellow-feathered Broilers

Sixty-four healthy yellow-feathered broilers of 1-day-old were selected and divided into group A and group B randomly, each group with 4 replicates in which had 8 yellow-feathered broilers. Group A fed the dietⅠ(include 5% fishmeal), group B fed the dietⅡ(include 2% fishmeal) in which added 0.5% small peptides. The trial lasted 8 weeks to investigate the effect of small peptides on growth performance and biochemical parameters of the yellow feathered broilers. The results showed that used a small number of small peptide products to replace a certain amount of fish meal in the diet reducing dietary protein content, even made yellow feathered broilers have higher growth performance. Also the content of the serum protein and serum albumin were significantly（P<0.05）increased and the serum total cholesterol were significantly（P<0.05）reduced in the 2-week-old of yellow-feathered broilers.
