【摘要】：试验旨在研究儋州鸡日粮中添加黄秋葵对其生长性能、屠宰性能、肉品质及消化酶活性的影响。选用健康、体重相近的90日龄儋州公鸡120只,随机分为5组,每组3个重复,每个重复8只鸡。对照组饲喂基础日粮,Ⅰ~Ⅳ组分别在基础日粮中添加0.5%、1.0%、1.5%、2.0%黄秋葵粉。试验期28d。结果显示:与对照组相比,Ⅰ~Ⅲ组平均日增重显著提高(P0.05),料重比显著降低(P0.05),Ⅳ组与对照组相比差异不显著(P0.05);与对照组相比,Ⅱ、Ⅲ组屠宰体重、屠宰率、全净膛率、半净膛率、胸肌重均显著提高(P0.05),Ⅰ组除屠宰体重显著高于对照组外(P0.05),其余指标与对照组间差异均不显著(P0.05),Ⅳ组各指标与对照组相比差异均不显著(P0.05);Ⅰ~Ⅲ组滴水损失率、剪切力显著低于对照组(P0.05);熟肉率、肌肉pH显著高于对照组(P0.05);Ⅱ、Ⅲ组胰腺、十二指肠、空肠中胰蛋白酶、脂肪酶、淀粉酶活性均显著高于对照组(P0.05),Ⅳ组除脂肪酶活性显著高于对照组外(P0.05),其余与对照组间差异均不显著(P0.05)。结果提示,在基础日粮中添加黄秋葵粉的适宜比例为1.5%,可有效改善儋州鸡的生长性能、屠宰性能、肉品质及消化酶活性。
[Abstract]:The purpose of the experiment was to study the effects of adding sunflower to the diet of Danzhou chicken on growth performance, slaughter performance, meat quality and digestive enzyme activity. 120 healthy 90 day old Danzhou cocks with similar body weight were randomly divided into 5 groups with 3 replicates in each group and 8 chickens in each replica. The control group was fed the basal diet, and the 鈪，
