摘要
为探讨茶园地散养方式对瑶山鸡生长及屠宰性能的影响,选用30日龄、体重基本一致的瑶山鸡共计120只,随机分为2组,每组各60只,每组再分为6个重复小组,每小组10只。分别采用一般坡地散养和茶园地散养方式进行饲养。饲养至90日龄时进行屠宰,并对生产及屠宰性能相关指标进行测定。结果显示:一般坡地散养方式的瑶山鸡90日龄体重低于茶园地散养组、平均日增重显著低于茶园地散养组(P<0.05),料重比高于茶园散养组;茶园地瑶山鸡90日龄的屠体重、半净膛重、全净膛重、腿肌重和瘦肉率均高于坡地散养组,但差异不显著(P>0.05);茶园地散养组的肝重、脾脏重显著高于一般坡地散养组(P<0.05);茶园地散养组瑶山鸡的组氨酸、精氨酸、肌苷酸含量显著高于一般坡地散养组(P<0.05),其他指标差异不显著(P>0.05)。综上表明,与一般坡地散养方式相比较,茶园地散养方式更利于瑶山鸡的生长。
This study aimed to assess the effect of the free-range mode in tea garden on the growth and slaughtering performance of Yaoshan chickens. A total of 120 30-day-old Yaoshan chickens with the similar body weight were selected and randomly divided into two groups (n=60 for each group). There were 6 repeats in each group with 10 chickens in each repeat. The chickens in the two separate group were free-range reared in tea garden and sloping fields, respectively. The chickens were slaughtered at the age of 90 days, and the indicators associated with growth and slaughtering performance of the two groups were determined and statistically compared. The results showed that the Yaoshan chickens reared in sloping fields had lower 90-day-old body weight, significantly lower average daily gain (P<0.05) and higher feed gain ratio compared to those reared in tea garden;the slaughtering weight, semi-net weight, total net weight, leg muscle weight and lean meat rate of the 90-day-old Yaoshan chickens reared in tea garden were higher than those reared in sloping fields, but no significant differences were observed (P>0.05);significantly higher liver weight and spleen weight were observed in tea garden reared group than sloping fields reared group (P<0.05);the Yaoshan chickens reared in tea garden had significantly higher content of histidine, arginine and inosinic acid compared to their counterparts reared in sloping fields (P<0.05), and no significant differences in the other tested nutritional component between the two groups were observed (P>0.05). It was indicated that the free-range rearing in tea garden was more conducive to the growth of Yaoshan chickens compared to the free-range rearing in sloping fields.
