1、2014年第35卷第16期总第469期=氢杨耨素劝瑶山鸡生长、屠宰牲链及血清抗螽化指标硇影响■戴青郁建平龚飞余心哲(贵州大学药学院，贵州贵阳550025)摘要：研究旨在观察藤茶中二氢杨梅素(dihydromyricetin，DMY)对瑶山鸡生长性能、屠宰性能及血清抗氧化指标的影响。选取40日龄健康贵州瑶山鸡96只，随机分为4个处理，每个处理3个重复，每个重复8只鸡。以饲喂基础日粮为对照组，试验组在基础日粮中分别添加0．025％、0．05％和0．1％的二氢杨梅素(DMY)，试验期70d。结果表明：日粮中添加不同剂量的DMY对瑶山鸡的生长性能有一定的促进作用，

2、添加0．05％的DMY极显著提高了瑶山鸡的全期日增重与日采食量(PO．05)，但0．05％的DMY可极显著提高瑶山鸡的胸肌率(P<0．01)；DMY可显著降低瑶山鸡血清中丙二醛(MDA)的含量(P<0．05)，且0．025％和0．1％的DMY可极显著降低过氧化氢酶(CAT)的活性(P<0．01)，但对瑶山鸡体内超氧化物歧化酶(SOD)活性无显著影响(P>0．05)。综上所述，日粮中添加DMY可提高瑶山鸡的生长性能，一定程度上改善屠宰性能
