中草药饲料添加剂对肉羊生产性能及血液生化指标的影响

Effects of Chinese Herbal Feed Additives on Performance and Blood Biochemical Indexes of Meat Sheep

试验为研究复方中草药作为饲料添加剂对肉羊生产性能及血液指标的影响,将100只健康状况良好且体重相近的6月龄肉羊,随机分为试验组和对照组(5重复/组,10只/重复)。试验组按照在基础饲粮中添加0.5%的复方中草药投喂30 d,对照组只饲喂基础饲粮,对生长性能及血液生化指标进行测定。结果表明:试验组比对照组的末重、平均日增重分别提高了2.79%、18.18%,料肉比降低了14.28%;平均日增重、料肉比与对照组差异显著(P<0.05);总蛋白(TP)、球蛋白(GLO)分别提高了14.69%、34.66%,TP、GLO显著高于对照组(P<0.05),天门冬氨酸转移酶(AST)、丙氨酸氨基转移酶(ALT)、肌酸激酶(CK)分别降低了28.29%、24.14%、29.57,AST、ALT、CK,显著低于对照组(P<0.05)。研究表明,在日粮中添加0.5%的中草药添加剂,可以有效提高肉羊的生产性能,对血液生化指标起到积极有效的作用。

To investigate the effects of Chinese herbal additives on growth performance and blood biochemical indexes of Barmei meat sheep,1006-month-old meat sheep with similar body weight and good body condition were randomly divided into 2 groups(experimental group and control group)with 5 replicates per group and 10 sheep per replicate.The experimental group was fed with 0.5%Chinese herbal additives in the diet for 30 days,and the control group only fed the basic diet.Growth performance and blood biochemical indexes were measured after feeding for 30 days.The results showed as follows:Compared with the control group,the final weight and average daily gain feed to meat ratio of experimental group increased by 2.79%and 18.18%,respectively,and the feed to meat ratio decreased by 14.28%.The average daily gain and ratio of feed to meat were significantly different from control group(P<0.05).Total protein(TP)and globulin(GLO)were increased by 14.69%and 34.66%,respectively.TP and GLO were significantly higher than control group(P<0.05),aspartate transferase(AST),ala-nine aminotransferase(ALT)and creatine kinase(CK)were decreased by 28.29%,24.14%and 29.57,respectively.AST,ALT and CK were significantly lower than those in control group(P<0.05).Studies have shown that adding 0.5%of Chinese herbal additives to the diet can effectively improve the production performance of mutton sheep,and can play a positive and ef-fective role in blood biochemical indexes.
