【摘要】：試驗旨在研究儋州雞日糧中添加黃秋葵對其生長性能、屠宰性能、肉品質(zhì)及消化酶活性的影響。選用健康、體重相近的90日齡儋州公雞120只,隨機分為5組,每組3個重復,每個重復8只雞。對照組飼喂基礎(chǔ)日糧,Ⅰ~Ⅳ組分別在基礎(chǔ)日糧中添加0.5%、1.0%、1.5%、2.0%黃秋葵粉。試驗期28d。結(jié)果顯示:與對照組相比,Ⅰ~Ⅲ組平均日增重顯著提高(P0.05),料重比顯著降低(P0.05),Ⅳ組與對照組相比差異不顯著(P0.05);與對照組相比,Ⅱ、Ⅲ組屠宰體重、屠宰率、全凈膛率、半凈膛率、胸肌重均顯著提高(P0.05),Ⅰ組除屠宰體重顯著高于對照組外(P0.05),其余指標與對照組間差異均不顯著(P0.05),Ⅳ組各指標與對照組相比差異均不顯著(P0.05);Ⅰ~Ⅲ組滴水損失率、剪切力顯著低于對照組(P0.05);熟肉率、肌肉pH顯著高于對照組(P0.05);Ⅱ、Ⅲ組胰腺、十二指腸、空腸中胰蛋白酶、脂肪酶、淀粉酶活性均顯著高于對照組(P0.05),Ⅳ組除脂肪酶活性顯著高于對照組外(P0.05),其余與對照組間差異均不顯著(P0.05)。結(jié)果提示,在基礎(chǔ)日糧中添加黃秋葵粉的適宜比例為1.5%,可有效改善儋州雞的生長性能、屠宰性能、肉品質(zhì)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，
