精油有机酸复合物对广西三黄鸡生长性能、血常规、血清生化指标和肉品质的影响

Effects of essential oil organic acid complex on growth performance,blood routine,serum biochemical indexes,and meat quality of Guangxi Sanhuang chickens

试验旨在探究精油有机酸复合物对广西三黄鸡生长性能、血常规、血清生化及肉品质的影响。随机挑选体重、生理状态一致的240只72日龄(育肥期)广西三黄鸡分为两组,每组重复6个,每个重复20只。对照组饲喂基础饲粮,试验组饲喂含0.25 g/kg精油有机酸复合物的饲粮。试验期42 d。结果显示:试验组三黄鸡的末重、平均日增重均显著高于对照组(P<0.05),料重比显著低于对照组(P<0.05),死淘率比对照组降低了25.04%(P>0.05)。试验组三黄鸡大血小板比率显著低于对照组(P<0.05)。试验组三黄鸡血清谷丙转氨酶活性、总胆固醇含量和甘油三酯含量均显著低于对照组(P<0.05),谷草转氨酶活性、谷草/谷丙比值均显著高于对照组(P<0.05)。试验组三黄鸡胸肌的剪切力显著低于对照组(P<0.05)。研究表明,精油有机酸复合物对广西三黄鸡生长性能、血清生化指标和肉品质具有正向调控作用,可作为一种替抗产品应用于广西三黄鸡的养殖。

The purpose of this experiment was to explore the effects of essential oil organic acid complex on the growth performance,blood routine,serum biochemical indexes,and meat quality of Guangxi Sanhuang chickens.A total of 240 chickens of 72-day-old(finishing period)with the same body weight and physiological state were randomly selected and divided into two groups,with six replicates in each group and 20 chickens in each replicate.The control group was fed with basal diet,while the experimental group was fed with a diet containing 0.25 g/kg essential oil organic acid complex.The trial period was 42 days.The results showed that the final weight and average daily weight gain of the experimental group were significantly higher than those of the control group(P<0.05),the feed-to-weight ratio was significantly lower than that of the control group(P<0.05),and the death rate was reduced by 25.04%(P>0.05).The ratio of large platelets in the experimental group was significantly lower than that in the control group(P<0.05).Serum alanine aminotransferase activity,total cholesterol content,and triglyceride content in the experimental group were significantly lower than those in the control group(P<0.05),while aspartate aminotransferase activity and aspartate/alanine aminotransferase ratio were significantly higher than those in the control group(P<0.05).The shear force of breast muscle of Sanhuang chickens in the experimental group was significantly lower than that in the control group(P<0.05).The study indicates that the essential oil organic acid complex has positive effects on growth performance,serum biochemical indexes,and meat quality of Guangxi Sanhuang chickens,and can be used as a substitute anti-drug product in Guangxi Sanhuang chickens breeding.
