添加黄秋葵对儋州鸡生长性能、屠宰性能、肉品质及消化酶活性的影响
Effects of Adding Okra on Growth Performance, Slaughter Performance, Meat Quality and Digestive Enzymes Activity of Danzhou Chickens
摘要
Abstract
The experiment was designed to study the effect of okra on the growth performance,slaughter performance,meat quality and digestive enzymes activity of Danzhou chicken.120 chicken with similar weight and 90 days old were selected randomly and divided into 5 groups with 3 replications per group and 8 chicken per replication.Control group was fed with basal diet,while chickens in groupsⅠ,Ⅱ,Ⅲ and Ⅳ were fed with the 0.5％,1.0％,1.5％ and 2.0％ okra added to basal diet,respectively.The trial lasted for 28 d.The results showed that compared with control group,the average daily gain of groups Ⅰ,Ⅱ and Ⅲ were significantly increased (P＜0.05),the F/G were significantly decreased (P＜0.05),while group Ⅳ showed no significant significance with control group (P＞0.05);The slaughter weight,slaughter rate,eviscerated rate,half eviscerated rate and chest muscle weight of groups Ⅱ and Ⅲ were significantly increased (P＜0.05).The slaughter weight of group Ⅰ was significantly increased (P＜0.05),while other indexes were showed no significant difference with control group (P＞0.05).All slaughter performance indexes of group Ⅳ were showed no significant difference with control group (P＞0.05).The drip loss rate and shear force in groups Ⅰ,Ⅱ and Ⅲ were significantly lower than control group (P＜0.05),while the cooked meat rate and pH value were significantly increased (P＜0.05).The trypsin,lipase and amylase activity of pancreas,duodenum and jejunum in groups Ⅱ and Ⅲ were significantly higher than that of control group (P＜0.05),while except lipase activity,group Ⅳ showed no significant difference with control group (P＞0.05).The results suggested that the addition of okra in the basal diet was 1.5 ％ which could significantly improve the growth performance,slaughter performance,meat quality and digestive enzymes activity of Danzhou chicken.关键词
