维康对肥育猪的饲喂试验

本研究旨在观察比较不同饲料添加剂对肥育猪生产性能的影响。选用体重20 kg左右的杜长大三元杂交（杜洛克×长白×大约克）瘦肉型商品猪100头,随机分为5组,每组设2个重复,每个重复10头。每组使用相同基础日粮,分别使用四种不同饲料药物添加剂进行了饲喂试验,即在基础饲粮中添加A组喹烯酮25%预混料300 mg/kg、B组维康200 mg/kg、C组维康300 mg/kg、D组北里霉素10%预混料300mg/kg的添加剂,空白对照组不添加任何添加剂。饲养时间为83 d。本试验饲养效果观察结果表明：全期日增重试验A、D组和空白对照组差异不显著（p〉0.05）,B、C组和空白对照组差异显著（p〈0.05）,B组维康按照200 mg/kg添加日增重最高,饲料报酬最高,经济效益最好。

Feeding experiments of Weik on finishing pigs

This experiment was conducted to study the effect of feed additive on growth performance in finishing pigs.100 crossed-bred(Duroc×Landrace×Yorkshine) pigs weighing an average of 20kg were randomly assigned to five dietary treatments with two replicates and ten pigs in each replicate.All the pigs in the groups were received the same basal diet and the basal diet were supplemented with 300mg/kg premix(25% quinocetone) in group A,200mg/kg Weik in group B,300mg/kg Weik in group C,200mg/kg premix(10% kitasamycin) in group D or nothing in the control group.The feeding trial lasted for 83 days.The results showed that there was no significant difference in group A,D with the control group on daily gain(ADG)(p>0.05) and there was significant difference in group B,C with the control group on daily gain(ADG)(p<0.05) in the whole period.The effects on daily gain(ADG),feed efficiency and economic benefits in group B(200 mg/kg Weik) were the best.
