摘要
为研究单宁酸对肉仔鸡生产性能和消化道酶活性的影响,选取2400只1日龄健康AA肉仔鸡随机分为4个处理,每个处理6个重复,每个重复100只鸡。分别饲喂4种日粮,分别为基础日粮、基础日粮+0.05%单宁酸、基础日粮+0.10%单宁酸、基础日粮+0.15%单宁酸。结果显示,单宁酸对肉仔鸡前期生长有显著抑制作用(P<0.05),对后期生长速度、饲料报酬均有显著改善作用(P<0.05);可以显著提高生长后期肉仔鸡淀粉酶、胰蛋白酶、脂肪酶活性(P<0.05)。研究表明加入适量的单宁酸(1.5kg/t)可以明显改善肉鸡后期生产性能和提高消化酶活性。
To study the effect of tannic acid on production performance and digestive enzyme activity of broiler, 2400 one-day-age AA broilers were randomly divided into four treatments with six replicates,each replicate per 100 chickens. 4 kinds of diets were fed respectively：basal diet,basal diet ＋0.05% tannic acid,basal diet ＋0.10% tannic acid,basal diet ＋0.15% tannic acid. The results showed that production performance of broiler were inhibited by tannic acid at first period （1 to 21 days age）significantly and improved at second period （22 to 42 days age）. The activities of amylase, trypsin and lipase of tannic acid groups were increased at second period （22 to 42 days age）. Above all,appropriate tanic acid （1.5 kg/t）could significantly improve production performance and digestive enzyme activity of broiler at second period.
