摘要

本试验旨在研究不同水平水溶性苜蓿多糖（WSAP）对肉仔鸡生长性能、胴体品质及生长激素（GH）和胰岛素样生长因子-1（IGF-1）基因表达的影响。选取1日龄艾维茵肉仔鸡360只，随机分为4组，每组6个重复，每个重复15只鸡。对照组饲喂基础饲粮，试验组饲喂在基础饲粮基础上分别添加0.5%、1.0%、1.5% WSAP的试验饲粮，试验期42 d。结果表明：与对照组相比，添加1.0%和1.5% WSAP显著提高了第42天平均体重（P<0.05），显著或极显著提高了生长后期（21~42 d）和全期（1~42 d）的平均日增重和平均日采食量（P<0.05或P<0.01），显著降低了生长后期和全期的料重比（P<0.05）；显著提高了胸肌率（P<0.05），显著降低了腹脂率（P<0.05）；添加WSAP还显著或极显著地提高了GH和IGF-1基因在肝脏、脂肪组织和肾脏中的表达（P<0.05或P<0.01）。综合分析认为，WSAP可提高GH和IGF-1基因在肉仔鸡组织中的表达量，促进肉仔鸡的生长，改善胴体品质，以1.0%的添加水平效果较好。

Abstract

This trial was conducted to investigate the effects of water soluble alfalfa polysaccharide (WSAP) on growth performance, carcass quality, growth hormone (GH) and insulin-like growth factor-1 (IGF-1) gene expressions of broilers. A total of 360 1-day-old Avian broilers were randomly divided into 4 groups with 6 replicates per group and 15 broilers per replicate, which were fed a basal diet (control group), and the basal diet+0.5%, 1.0% and 1.5% WSAP for 42 days, respectively. The results showed as follows: compared with control group, the broilers fed 1.0% and 1.5% WSAP had higher average body weight at day 42(P<0.05), average daily feed intake and average daily gain (P<0.05 or P<0.01) and had lower feed to gain ratio (P<0.05) at the later stage (21 to 42 d) and the whole stage (1 to 42 d); WSAP could also improve the percentage of breast muscle (P<0.05) and decrease the percentage of abdominal fat (P<0.05); meanwhile, WSAP enhanced the GH and IGF-1 gene expressions in liver, adipose and kidney (P<0.05 or P<0.01). The results suggest that WSAP can enhance the GH and IGF-1 gene expressions, and improve the growth performance and the carcass quality of broilers. It is recommended that the optimal supplemental level of WSAP is 1.0%.

Key words： broilers; water soluble alfalfa polysaccharides; growth performance; carcass quality; GH; IGF-1
