摘要 试验旨在研究腹腔注射葡萄糖对肉鸡食欲的影响。选取16只相同生长环境下生长状况相近的28日龄AA肉鸡,随机分为2个处理,每个处理4个重复,每个重复2只鸡,试验组注射1.1g/mL的葡萄糖(500mg/kg),对照组注射等体积生理盐水,试验共进行三次注射,每次间隔12h,前两次注射前禁饲1h,最后一次注射后采血并屠宰取肝脏样品,统计其24h内采食量并测定其血液中营养代谢物的变化及肝脏中脂肪酸合成酶(FAS)表达量的变化。结果显示:腹腔注射葡萄糖可在1~2h内影响肉鸡的食欲,使肉鸡采食量降低;试验组肉鸡血液中的葡萄糖和甘油三酯水平显著高于对照组(P〈0.05),尿素和总胆固醇水平与对照组相比显著降低(P〈0.05);试验组肝脏中FAS基因的表达量显著升高(P〈0.05)。研究表明腹腔注射葡萄糖会在短期内降低肉鸡的食欲,并对血液中营养代谢物及肝脏中脂肪代谢有一定影响。
