酵母铬对肉仔鸡脂类代谢及生产性能影响的研究

EFFECT OF YEAST CHROMIUM ON THE PERFORMANCE AND LIPOMETABOLISM OF BROILERS

本试验以艾维茵肉仔母鸡为研究对象，研究了日粮添加40μg／kg酵母铬对肉仔鸡生产性能及脂类代谢的影响。试验结果表明：日粮补铬对生产性能无显著影响（P＞0．05）；补铬显著降低了肉仔鸡的腹胀（P＜0.05）和血清中甘油三酯（TG）（P＜0．01）的含量；而肝脂含量及血清中的高密度脂蛋白胆固醇（HDL－C）、低密度脂蛋白胆固醇（LDL－C）、总胆固醇（TC）在处理间无显著差异（P＞0．05）。

Female Avian broilers were used as animal model to determine the effect of dietary supplemental 400μg / kg yeast chromium on the lipometabolism and performance of broilers. The results demonstrated that chromium supplementation had no significant effect on the broiler performance(P >0. 05), but significantly decreased abdominal fat content(P <0. 05) and serum triglyceride level(TG) (P <0. 01). Hepatic fat content, levels of serum high density lipoprotein cholesterol(HDL - C), low density lipoprotein cholesterol (LDL - C) and total cholesterol(TC) were not affected by the dietary treatment(P >0. 05).
