摘要

本试验旨在研究饲粮中添加不同水平的金银花提取物对蛋鸡生产性能、蛋品质、脂质代谢及蛋黄胆固醇含量的影响。试验选用34周龄体况健康、产蛋率接近的京粉2号蛋鸡600只,随机分成4组,每组5个重复,每个重复30只鸡。对照组饲喂基础饲粮,试验组分别饲喂在基础饲粮中添加100、200和300 mg/kg金银花提取物的试验饲粮。试验期35 d。结果表明:1)与对照组相比,300 mg/kg组平均蛋重和平均日采食量显著增加(P<0.05)。2)与对照组相比,各试验组的哈氏单位均显著提高(P<0.05)。3)与对照组相比,各试验组血清总胆固醇和甘油三酯含量均显著降低(P<0.05),200和300 mg/kg组血清高密度脂蛋白胆固醇含量显著增加(P<0.05),200和300 mg/kg组蛋黄胆固醇含量显著降低(P<0.05)。由此可见,饲粮中添加金银花提取物可以提高平均蛋重、平均日采食量和鸡蛋哈氏单位,改善蛋鸡脂质代谢,降低蛋黄胆固醇含量,其中以300 mg/kg组效果最为明显。

Abstract

The aim of this study was to investigate the effects of dietary different levels of honeysuckle extract on performance, egg quality, lipid metabolism and yolk cholesterol content of laying hens. Six hundred healthy Jingfen No.2 laying hens aged at 34 weeks with similar laying rate were randomly divided into 4 groups with 5 replicates per group and 30 hens per replicate. Hens on the control group were fed a basal diet, and others in the experimental groups were fed the basal diets supplemented with 100, 200 and 300 mg/kg honeysuckle extract, respectively. The results showed as follows:1) compared with the control group, the average egg weight and average daily feed intake of 300 mg/kg group were significantly increased (P<0.05). 2) Compared with the control group, the Haugh unit of experimental groups was significantly increased (P<0.05). 3) Compared with the control group, the contents of total cholesterol and triglyceride in serum of experimental groups were significantly decreased (P<0.05), the serum high density lipoprotein cholesterol content of 200 and 300 mg/kg groups was significantly increased (P<0.05), the yolk cholesterol content of 200 and 300 mg/kg groups was significantly decreased (P<0.05). These results indicates that dietary honeysuckle extract can increase the average egg weight, average daily feed intake and egg Haugh unit, improve the lipid metabolism, reduce the yolk cholesterol content, and the effect of 300 mg/kg group is the most obvious.
