摘要

本试验旨在研究饲粮代谢能和粗蛋白质水平对0~4周龄大午粉1号商品代蛋雏鸡生长性能、体尺性状、器官指数、血清生化指标的影响，通过建立所检测指标与饲粮代谢能或粗蛋白质水平的回归模型，确定0~4周龄大午粉1号商品代蛋雏鸡饲粮中适宜的代谢能和粗蛋白质水平。试验采用3×3双因素试验设计，设定饲粮中代谢能水平12.01、12.51和13.01 MJ/kg，粗蛋白质水平分别为19.81%、20.81%和21.81%，共配制9种试验饲粮。选取810只遗传背景相同、体重接近、健康状态良好的1日龄大午粉1号商品代蛋雏鸡，随机分为9组，每组6个重复，每个重复15只鸡。饲养试验持续28 d。结果显示：1）饲粮中代谢能水平显著影响雏鸡的平均日采食量（ADFI）、平均日增重（ADG）、料重比（F/G）、龙骨长、体重以及十二指肠和回肠相对长度（P<0.05），且与雏鸡的ADFI、F/G以及血清中葡萄糖（GLU）、甘油三酯（TG）、总胆固醇（TC）含量呈显著的二次曲线关系（P<0.05）。2）饲粮中粗蛋白质水平显著影响雏鸡的胸宽、肝脏指数、十二指肠与回肠相对长度（P<0.05），且与雏鸡的胸宽呈显著的二次曲线关系（P<0.05）。3）饲粮中代谢能和粗蛋白质水平的互作效应对雏鸡的ADG、F/G、十二指肠与回肠相对长度以及血清中TG含量有显著影响（P<0.05）。4）通过拟合二次曲线，得出饲粮代谢能水平为6.991、12.979、10.524、11.968和11.775 MJ/kg时，雏鸡的ADFI、F/G以及血清中GLU、TG和TC含量分别达到最佳水平；饲粮中粗蛋白质水平为20.402%、20.730%时，雏鸡的肝脏指数、胸宽分别达到最佳水平。综合生长性能、体尺性状、器官指数、血清生化指标，推荐0~4周龄大午粉1号商品代蛋雏鸡饲粮中代谢能水平为11.812 MJ/kg，粗蛋白质水平为20.566%。

Abstract

To determine the optimal dietary metabolizable energy (ME) and crude protein (CP) levels of hatch to 4-week-age Dawufen No.1 commercial layer chicks, the effects of dietary ME and CP levels on the growth performance, body size traits, organ indexes and serum biochemical indexes of 0 to 4-week-age Dawufen No.1 commercial layer chicks were evaluated, and the regression models between the dietary ME or CP levels and testing indexes were built. A 3×3 two-factor experiment design was adopted in this experiment. Nine experimental diets were prepared, the ME levels in diets were 12.01, 12.51 and 13.01 MJ/kg, respectively, and the CP levels in diets were 19.81%, 20.81% and 21.81%, respectively. Eight hundred and ten 1-day-old Dawufen No.1 commercial layer chicks with the same genetic background, similar body weight and good health were randomly divided into 9 groups with 6 replicates per group and 15 chicks per replicate. The experiment lasted for 28 days. The results showed as follows:1) dietary ME level had significant effects on the average daily gain (ADG), average day feed intake (ADFI), feed/gain (F/G), keel length, body weight, duodenum relative length and ileum relative length of layer chicks (P<0.05), and there was a significant quadratic curve relationship between dietary ME level and ADFI, F/G, the contents of serum glucose (GLU), triglyceride (TG) or total cholesterol (TC) (P<0.05). 2) Dietary CP level had significant effects on the chest width, liver index, duodenum relative length and ileum relative length (P<0.05), and there was a significant quadratic curve relationship between dietary CP level and chest breadth (P<0.05). 3) The interaction of dietary ME and CP levels had significant effects on ADG, F/G, duodenum relative length, ileum relative length and serum TG content (P<0.05). 4) According to fit quadratic curve, the best levels of ADFI, F/G, serum GLU, TG and TC contents were obtained when dietary ME levels were 6.991, 12.979, 10.524, 11.968 and 11.775 MJ/kg, respectively, and the best levels of liver index and chest breadth were obtained when dietary CP levels were 20.402% and 20.730%, respectively. Overall, when growth performance, body size traits, organ indexes and serum biochemical indexes are considered together, the optimal dietary ME and CP levels for 0 to 4-week-age Dawufen No.1 commercial layer chicks are 11.812 MJ/kg and 20.566%, respectively.
