摘要

本试验旨在研究饲粮能量和蛋白质水平对61~120日龄断奶湖羊羔羊生长性能、氮代谢及血清生化指标的影响。采用2×2两因素两水平试验设计，选取64只61日龄体重相近的纯种湖羊羔羊，随机分为4组，饲喂不同能量和蛋白质水平的饲粮，分别为高能量[代谢能（ME）为10.92 MJ/kg]高蛋白质[粗蛋白质（CP）为15.74%]组、高能量（ME为10.92 MJ/kg）低蛋白质（CP为11.78%）组、低能量（ME为8.64 MJ/kg）高蛋白质（CP为15.72%）组、低能量（ME为8.64 MJ/kg）低蛋白质（CP为11.82%）组，每组4个重复，每个重复4只，公母各占1/2。试验期60 d。结果表明：1）饲粮能量与蛋白质水平对羔羊生长性能指标不存在交互作用（P>0.05）；饲粮高能量高蛋白质水平显著提高了羔羊61~90日龄的平均日增重（P<0.05），显著降低了料重比（P<0.05）。2）饲粮高蛋白质水平显著提高了81~90日龄、111~120日龄羔羊氮摄入量（P<0.05）；饲粮低能量高蛋白质水平显著提高了81~90日龄、111~120日龄羔羊尿氮排出量（P<0.05），并且以低能量高蛋白质组尿氮排出量最高；对于81~90日龄羔羊，饲粮高能量高蛋白质水平显著提高了氮沉积（P<0.05），而饲粮低能量或高蛋白质水平显著降低了氮生物学效价（P<0.05）。3）羔羊120日龄时，饲粮低能量水平显著降低了血清葡萄糖含量（P<0.05），显著提高了血清尿素氮含量（P<0.05）；饲粮低蛋白质水平显著提高了血清胰岛素样生长因子Ⅰ含量（P<0.05）。综上所述，61~90日龄阶段，饲粮高能量高蛋白质水平可促进羔羊生长；91~120日龄阶段，可适当降低饲粮蛋白质水平以节约生产成本，不会对生长性能产生不利影响。

Abstract

This experiment was conducted to investigate the effects of dietary energy and protein levels on growth performance, nitrogen metabolism and serum biochemical indices of Hu lambs at 61 to 120 days of age. With a 2×2 two factors and two levels experimental design, sixty-four Hu lambs with similar body weight at 61 days of age were randomly allocated into 4 groups, which were high energy[metabolizable energy (ME)=10.92 MJ/kg] and high protein[crude protein (CP)=15.74%] group, high energy (ME=10.92 MJ/kg) and low protein (CP=11.78%) group, low energy (ME=8.64 MJ/kg) and high protein (CP=15.72%) group, and low energy (ME=8.64 MJ/kg) and low protein (CP=11.82%) group; each group had 4 replicates with 4 lambs per group. The experimental period lasted for 60 days. The results showed as follows:1) no interaction was observed between dietary energy and protein levels on growth performance of lambs (P>0.05); high dietary energy and protein levels improved average daily gain of lambs at 61 to 90 days of age (P<0.05), and significantly decreased feed to gain ratio (P>0.05). 2) Dietary high protein level significantly increased nitrogen intake of lambs at 81 to 90 days of age and 111 to 120 days of age (P<0.05); dietary low energy and high protein level significantly increased urinary nitrogen output of lambs at 81 to 90 days of age and 111 to 120 days of age (P<0.05), and low energy and high protein group had the highest value; at 81 to 90 days of age, dietary high energy and high protein levels significantly increased nitrogen retention (P<0.05), while dietary low energy level or high protein level significantly decreased biological value of nitrogen (P<0.05). 3) At 120 days of age, dietary low energy level significantly decreased serum glucose content (P<0.05), significantly increased serum urinary nitrogen content (P<0.05); moreover, dietary low protein level significantly increased serum insulin-like growth factor Ⅰ content (P<0.05). In summary, dietary high energy and protein levels can improve growth performance of lambs at 61 to 90 days of age; however, the feeding cost of lambs can be controlled without affecting growth performance with low protein diet at of 91 to 120 days of age.
