【摘要】：试验旨在研究日粮添加胆汁酸对肉鸡生产性能、血液生化指标以及屠宰性能的影响。选取2 400只1日龄AA肉仔鸡,分为4个处理,每个处理6个重复,每个重复100只。处理1(公鸡)和处理2(母鸡)饲喂基础日粮,处理3(公鸡)和处理4(母鸡)饲喂添加500 g/t胆汁酸的日粮。在21和35日龄时统计生产性能。36日龄时,每个重复随机选取两只鸡静脉采血后屠宰,测定血清生化指标及屠宰性能。结果显示:饲养前期(1~21 d),日粮添加胆汁酸显著提高了公鸡和母鸡平均体重、平均体增重和欧洲效益指数(P0.05),料肉比有降低趋势(P0.1);饲养全期,公鸡生产性能极显著高于母鸡(P0.01),日粮添加胆汁酸显著提高了肉鸡血液中总胆固醇的含量(P0.05),显著提高了肉鸡的腿肌率(P0.05),胸肌率也有升高的趋势(P0.1),母鸡的腹脂率显著高于公鸡(P0.05)。结果表明,胆汁酸能显著提高肉鸡前期生产性能,并且能改善肉鸡屠宰性能,对血液中脂肪代谢也有一定影响。
[Abstract]:Study of dietary bile acids on broiler performance, blood biochemical indices and the effect of slaughter performance. A total of 2400 1 day old AA broilers were divided into 4 treatments with 6 replicates of 100 birds per replicate. 1 (male) and 2 (HEN) basal diet 3, (male) and 4 (HEN) fed diet 500 g/t bile acid. In the 21 and 35 day old production performance statistics at.36 days of age, two chickens each replicate were randomly chosen in venous blood after slaughter, serum biochemical indexes and slaughter performance. The results showed that early feeding (1~21 d), dietary bile acids significantly increased the average weight of the cock and the hen, the average body weight gain and the European efficiency index (P0.05), feed conversion decreased ratio (P0.1); the whole feeding period, the production performance was significantly higher than that of the hen (P0.01), dietary bile acids significantly increased the blood of Broilers The content of total cholesterol (P0.05), significantly increased the rate of leg muscle of broilers (P0.05), also increased the percentage of breast (P0.1), abdominal fat hen was significantly higher than that of the cock (P0.05). The results showed that the bile acid can significantly improve broiler production performance in early stage, and can improve the performance of broiler slaughter, also have certain effect on blood fat metabolism.
