| 摘 要： | 试验旨在探究日粮中添加外源核苷酸对从肉鸡生产性能的影响.100只1日龄AA肉鸡随机分成4组:对照组,低、中、高剂量外源核苷酸试验组,每组25R.对照组饲喂基础日粮;试验组于22日龄开始,在基础日粮中分别添加0.05%、0.10%和0.20%外源核苷酸,试验期42d.采集血清分析生化指标,结果表明,与对照组相比,添加外源核苷酸显著提高了AA肉鸡增重和饲料利用率,显著提高胸肌和腿肌重量,同时显著降低腹脂率.添加外源核苷酸对血清中的总胆固醇和甘油三酯含量无显著影响,但可显著降低非酯化脂肪酸含量.结果提示,日粮中添加外源核苷酸能在提高AA肉鸡增重和肌肉重量的同时降低脂肪的沉积,从而提高生产性能. |

| Abstract: | The study mainly explored the effect of exogenous nucleotides on production performance of AA broilers. 100 one-day-age AA broilers were randomly divided into four groups:control group,low,middle and high dosage experimental groups. Each group had 25 broilers. The control group fed with basal diet. The other groups were fed with basal diet supplemented with nucleotides,and the concentrations were 0.05%,0.10% and 0.20%,respectively. This experiment lasted for 42 days. The results showed that exogenous nucleo... |
