摘要
将２５０羽艾维因鸡苗随机分为５组，分别设５个处理：第１组只喂基础日粮；第２组在基础日粮中加入泰县肉鸡添加剂；第３～５组分别在基础日粮中加入自配的１￣＃，２￣＃，３￣＃添加剂预混料。试验７周，结果以第１￣＃预混料处理的综合效果最好，７周龄时平均体重１．７１ｋｇ，料重比２．１９：１，育成率８８％，比不用添加剂预混料的第１组增重提高３８．４％，饲料报酬提高１１．７％，育成率提高９１．３％，每ｋｇ增重饲料成本降低０．９６元。
Ivin Chicks were divided into 5 groups randomly. The first group was onlyfed with basal diet,the second was fed with basal diet as well as broier feed additive pro-duced in Tai County,and the third to fifth groups were provided with basal diet with thepremix number 1,2,3 respectively adding to it.The experiment lasted seven weeks and theresults showed that the comprehensive effects of the premix number 1 were the best,whose average weight was 1. 71kg, feed coversion ratio was 2. 91 : 1 ,and the living ratewas 88%。 Compared with those of the first group ,the total chick-weight ,feed reward andliving rate was increased by 38.4%,11.7%and 91.3%respectively,while the cost was de-creased by 0. 96 yuan per kilogram feed.
