摘要

本试验旨在研究饲粮代谢能(ME)水平对鲁西斗鸡生长性能的影响,并得出鲁西斗鸡的生长变化规律。选用1日龄健康鲁西斗鸡1 000只,随机分为5个组,每个组4个重复,每个重复50只,试验期分1~6周龄和7~20周龄2个阶段。试验各阶段的ME水平分别为:1~6周龄,11.98、12.19、12.38、12.62、12.81 MJ/kg;7~20周龄,11.63、11.82、12.03、12.25和12.45 MJ/kg。结果表明:1)饲粮ME水平对鲁西斗鸡平均日采食量、平均日增重无显著影响(P>0.05),饲粮ME水平对7~20周龄鲁西斗鸡料重比有显著影响(P<0.05),全期料重比以中ME组(1~6周龄:12.38 MJ/kg;7~20周龄12.03 MJ/kg)最小。2)1~20周龄,鲁西斗鸡平均日采食量(ADFI)与周龄(t)的变化方程为ADFI=-0.01+5.73×t (R2=0.982 7,P<0.000 1);体重(BW)与周龄(t)变化方程为BW=1 607.60/(1+22.53e-0.27t) (R2=0.996 7,P<0.000 1)。由此可见,以全期最佳料重比为依据,鲁西斗鸡饲粮适宜ME水平1~6周龄为12.38 MJ/kg,7~20周龄为12.03 MJ/kg。

Abstract

This experiment was conducted to study the effects of dietary metabolizable energy (ME) level on growth performance and formulate the growth model of Luxi game chickens. A total of 1 000 one-day-old Luxi game chickens were randomly divided into 5 groups with 4 replicates per group and 50 chickens per replicate. The feeding period was divided into two stages: 1 to 6 and 7 to 20 weeks of age. The dietary ME levels were as follows: 1 to 6 weeks of age, 11.98, 12.19, 12.38, 12.62 and 12.81 MJ/kg; 7 to 20 weeks of age, 11.63, 11.82, 12.03, 12.25 and 12.45 MJ/kg. The results showed as follows: 1) average daily feed intake (ADFI) and average daily gain of chickens were not significantly affected by dietary ME level aged from 1 to 20 weeks (P>0.05), while dietary ME level significantly affected feed to gain of chickens aged from 7 to 20 weeks (P<0.05), and the middle ME level group (1 to 6 weeks of age: 12.38 MJ/kg;7 to 20 weeks of age: 12.03 MJ/kg) was the lowest during whole stage. 2) From 1 to 20 weeks of age, the best fitting models of ADFI, body weight (BW) with age (t) as follows: ADFI=-0.01+5.73×t (R2=0.982 7, P<0.000 1); BW=1 607.60/(1+22.53e-0.27t) (R2=0.996 7, P<0.000 1). In conclusion, according to the best feed to gain, the suitable ME level of Luxi game chickens aged from 1 to 6 and 7 to 20 weeks were 12.38 and 12.03 MJ/kg, respectively.
