圆叶决明种子粉对肉鸡血脂指标的影响

Effect of Feeding Chamaecrista Romndifolia Seed Powder on the Hemolipid Index of the Chicken

研究了圆叶决明种子粉对艾维茵（AA）肉鸡血脂指标的影响，并初步探讨了其机理。选取8周龄健康AA鸡240羽，采用单因子试验设计，随机分为2组，每组3次重复，每次重复40羽，对照组饲喂基础日粮，试验组日粮为基础日粮添加3g／羽圆叶决明种子粉（120目），试验期30天。观测圆叶决明种子粉对AA鸡生产性能、脂肪沉积指标、血脂指标、转氨酶活性的影响。结果表明：①在肉鸡生产性能方面，对照组和试验组没有显著差异（P〉0．05）；②圆叶决明种子粉具有显著降低脂肪沉积的作用；③圆叶决明种子粉能明显降低肉鸡血清总胆固醇（TCHO）、甘油三酯（TG）、低密度酯蛋白含量（LDL—C）（P〈0．05），显著升高血清高密度酯蛋白（HDL—C）含量（P〈0．05）；④通过对肉鸡谷丙转氨酶（AST）、谷草转氨酶（ALT）活性的检测，表明饲喂圆叶决明种子粉对肉鸡肝脏没有损伤作用。

Effect of feeding Chamaecrista Rotundifolia seed powder on the mophysiology index of the AA chicken＇ s blood and its mechanism were investigated. Using single factor design, 240 healthy S-week-old chickens were randomly divided into two groups,each group has three replications. The chickens in control group were given basic daily feed, the chickens in experimental group were given basic daily feed and 3 g/chicken of Chamaecrista Rotundifolia seed power （120 mesh）, the experiment was lasted for 30 days. Effect of Chamaecrista Rotundifolia seed power on chicken productivity, Parameters of lipid deposition, hemolipid index and activity of ammonium transformase were discovered. The results showed that, ① there was no significant difference in chicken productivity between two groups （P〉0.05）; ② Feeding Chamaecrista Rotundifolia seed powder deduced significantly parameters of lipid deposition; ③ Feeding Chamaecrista Rotundifolia seed powder deduced significantly TCHO, TG, LDL-C contents in the chicken serum （P〈0.05） and increased HDL-C content （P〈0.05）; ④ The sets to AST and ALT of experimental chicken showed that feeding Chamaecrista Rotundifolia seed powder has no hazard effect on chicken liver.
