低蛋白质日粮对河田鸡生长性能及血清生化指标的影响
Effects of Low-Protein Diets on Growth Performance and Serum Biochemical Parameters of Hetian Chicken
摘要
Abstract
1980 Hetian chickens (1-day old) were randomly separate into 2 groups (control and treatment groups) based on body weight with 3 replicates per group, 330 birds per replicate. The diets in control group are formulated based on the amino acid model and crude protein level of Nutrient Requirements of Chinese Color-feathered chicken (NY/T 33-2004) . The diets in treatment group are based on the amino acid model of NRC (1994) and 1% lower than the control diets in crude protein level. The growth performance and serum biochemical parameters were determined at day 28, 42, 75 and 105. The results showed as follows: the low-protein diets had no significant effect on body weight at each determination day except at day 28 (P<0. 05) . There were no significant differences on growth performance between two groups at each stage (P>0. 05) . Serum total protein level and ALP (Alkaline phosphatase) activity were slightly higher in treatment group (P>0. 05). However, The BUN (Blood Urea Nitrogen) and UA (Uric Acid) were slightly lower than control group (P>0. 05). From day 28 to day 105, serum total protein level significantly increased (P<0. 05),but BUN,UA and ALP were on a decreased trend(P>0. 05).关键词
