红车轴草异黄酮对肉鸡生产性能及肉品质的影响

为了研究红车轴草（Trifolium pratense）异黄酮对肉鸡生长、屠宰性能及肉品质的影响，将180羽1日龄AA肉仔鸡分成3组，即对照组、试验Ⅰ组、试验Ⅱ组，分别饲喂基础日粮、基础日粮+红车轴草异黄酮(10 mg/kg)、基础日粮+红车轴草异黄酮(20 mg/kg)。结果显示，红车轴草异黄酮可以提高肉鸡的日增体质量（P<0.05）和屠宰性能（P>0.05），降低血清中甘油三酯、总胆固醇和腹脂率（P<0.05），减少了储存第6天肉中丙二醛含量（P<0.05），降低了肉品滴水损失和剪切力（P>0.05）。表明红车轴草异黄酮能够提高肉鸡生长性能和屠宰性能，改善肉品品质，添加20 mg/kg时肉鸡日增长速度最快。

Effects of red clover isoflavone on production performance and meat quality in broilers

In order to study effects of red clover(Trifolium pratense) isoflavone on production performance and meat quality,one hundred and eighty 1-day-old AA broilers were randomly assigned to three groups,which were the fed with basic diet(control),the basic diet+red clover isoflavone(10 mg/kg) and the basic diet+red clover isoflavone(20 mg/kg),respectively.The results indicated that the red clover isoflavone could increase daily gain and slaughter performance(P<0.05),reduce the contents of triglyceride(TG),total cholesterol(TC) in serum and the percentage of abdominal fat of broiler(P<0.05).The contents of malondialdehyde(MDA)(P<0.05),drip loss and shear force of muscle were decreased after feeding red clover isoflavone(P>0.05).In conclusion,the red clover isoflavone could modulate growth performance and slaughter performance;improved meat quality in broilers.The broilers were fed with the diet content of 20 mg/kg red clover isoflavone had the highest daily gain.
