本试验旨在研究N-乙酰半胱氨酸(NAC)和冷应激对肉鸡肠道组织形态、能量状况和抗氧化能力的影响.试验将200只1日龄健康雄性科宝肉鸡随机分为4个处理组:对照组(基础日粮)、NAC组(基础日粮+0.1％NAC)、冷应激组(基础日粮)与冷应激+NAC组(基础日粮+0.1％NAC),每组5个重复,每个重复10只鸡.试验第1～2周按常规饲养方法控制温度,试验第3～6周冷应激组和冷应激+NAC组的温度控制在(10±2)℃,而对照组与NAC组维持在(26±2)℃.结果表明:冷应激处理使肉鸡平均日采食量、平均日增重、空肠低氧诱导因子1 (HIF-1) mRNA水平显著下降(P＜0.05),饲料转化率、回肠一磷酸腺苷(AMP)含量和空肠隐窝深度极显著升高(P＜0...

This experiment was conducted to investigate the effects of N-acetylcysteine （NAC） and cold stress on intestinal morphology, energy status and antioxidant capacity in broilers. The experiment was divided into 4 groups according to the factorial design （2 x 2）. Two hundred 1-day-old male Cobb chickens were randomly divided into 4 groups： control group （basal diet）, NAC group （basal diet ＋ 0.1% NAC）, cold-stressed group （basal diet）, and cold stress ＋ NAC group （basal diet ＋ 0.1% NAC）. Each group had 5 replicates with l0 chickens ...
