中草药和植物提取物菌酶复合制剂对黄羽肉鸡屠宰性能及肉品质的影响OA

The experiment aimed to investigate the effects of Chinese herbal medicine and plant extract bacterial enzyme complex preparation on the growth performance,slaughter performance,and meat quality of yellow-feathered broiler chickens.A total of 150 healthy yellow-feathered broiler chickens of similar weight at 90 days of age were randomly divided into three groups,with five replicates per group and ten chickens per replicate.The control group was fed with basal diet,the Chinese herbal medicine group was added with 1 500 g/t of Chinese herbal medicine in the basal diet,and the plant extract bacterial enzyme group was added with 1 000 g/t of plant extract bacterial enzyme complex preparation in the basal diet.The test period was 21 days.The results showed that compared with the control group,the plant extract bacterial enzyme group showed an increase in average daily gain and a decrease in feed to gain ratio.The eviscerated percentage of the Chinese herbal medicine group and the plant extract bacterial enzyme group increased,and the abdominal fat rate decreased by 6.67%and 1.52%,respectively.The Chinese herbal medicine group had the smallest chest muscle shear force.The 24-hour brightness(L*)value of the breast muscle in the plant extract bacterial enzyme group was significantly reduced(P<0.05),and the 24-hour redness(a*)value of the leg muscle was significantly increased(P<0.05).The 45-minute L* value of leg muscle in the Chinese herbal medicine group was significantly increased(P<0.05).The study shows that adding plant extract bacterial enzyme complex preparation to basic feed can promote the growth,reduce feed to gain ratio,and improve meat color of broiler chickens.Adding Chinese herbal medicine can improve muscle tenderness and reduce abdominal fat deposition.
