微生态制剂对林下散养北京油鸡生长性能、屠宰性能、器官指数、肉品质和免疫性能的影响OA
Effects of Microbial Ecological Agents on Growth Performance,Slaughter Performance,Organ Indices,Meat Quality and Immune Performance of Free Range Beijing Oil Chickens under Forest
为了研究微生态制剂对林下散养北京油鸡生长性能、屠宰性能、器官指数、肉品质和免疫性能的影响,将120只7周龄雌性北京油鸡随机分成4组,分别是基础组、0.05%添加组、0.10%添加组、0.20%添加组.4个处理组分别在基础饲粮中添加0、0.05%、0.10%、0.20%的微生态制剂.结果表明:①相比于基础组,0.10%添加组、0.20%添加组可显著提高北京油鸡的末重、平均日增重(P<0.05),显著降低北京油鸡的料重比(P<0.05).②相比于基础组,0.10%添加组、0.20%添加组可显著提高北京油鸡的全净膛率(P<0.05).③相比于基础组,0.10%添加组、0.20%添加组可显著提高北京油鸡的心脏指数、肝脏指数、肾脏指数(P<0.05).④相比于基础组,0.10%添加组、0.20%添加组可显著降低北京油鸡的滴水损失、蒸煮损失、剪切力(P<0.05).⑤相比于基础组,0.05%添加组、0.10%添加组、0.20%添加组可显著提高北京油鸡的免疫球蛋白G(IgG)、白细胞介素-2(IL-2)含量(P<0.05),0.10%添加组、0.20%添加组可显著提高北京油鸡的免疫球蛋白A(IgA)含量(P<0.05).添加0.10%、0.20%微生态制剂可显著改善林下散养北京油鸡的生长性能、屠宰性能、器官指数、肉品质和免疫性能,临床可选择0.10%添加剂量作为使用剂量.
In order to study the effects of microbial ecological agents on the growth performance,slaughter performance,organ indices,meat quality,and immune performance of free range Beijing oil chickens under forest,120 7-week-old female Beijing oil chickens were randomly divided into four groups:basic group,0.05%addition group,0.10%addition group,and 0.20%addition group.Four treatment groups added 0,0.05%,0.10%,and 0.20%of microbial ecological agents to their basic diets,respectively.The results showed that:① compared with the basic group,the 0.10%and 0.20%addition groups significantly increased the final weight and average daily weight gain of Beijing oil chickens(P<0.05),and significantly decreased the feed to weight ratio of Beijing oil chickens(P<0.05).② Compared with the basic group,the 0.10%and 0.20%addition group significantly increased the fully eviscerated yield of Beijing oil chickens(P<0.05).③ Compared with the basic group,the 0.10%and 0.20%addition groups significantly increased the heart index,liver index,and kidney index of Beijing oil chickens(P<0.05).④ Compared with the basic group,the 0.10%and 0.20%addition groups can significantly decrease the drip loss,cooking loss,and shear force of Beijing oil chickens(P<0.05).⑤ Compared with the basic group,the 0.05%addition group,0.10%addition group,and 0.20%addition group significantly increased the Immunoglobulin G(IgG)and Interleukin-2(IL-2)content of Beijing oil chickens(P<0.05),and the 0.10%addition group and 0.20%addition group significantly increased the Immunoglobulin A(IgA)content of Beijing oil chickens(P<0.05).Adding 0.10%and 0.20%microbial ecological agents can significantly improve the growth performance,slaughter performance,organ index,meat quality,and immune perfor-mance of free range chickens under forest.Clinically,a dosage of 0.10%can be chosen as the dosage for use.
