杜洛克母猪生长、肥育阶段补充维生素E和维生素C的效果

Different Effects of Vitamin E and Vitamin C Supplement in Female Duroc Growing and Finishing Pigs

在生长猪日粮 (含添加剂 VE7IU/ kg)中添加 VE5 0 IU/ kg和 VC10 0 mg/ kg,对杜洛克生长母猪的生产性能无明显影响 ,肥育猪日粮 (含添加剂 VE 4.9IU/ kg)中添加 VE 2 5 IU / kg和 VC 5 0 mg/kg,可提高日增重 8.6 % ,单位增重的饲料消耗下降 11.7%。表明杜洛克母猪肥育日粮的 VE和 VC水平可能应高于生长阶段。

IU/kg vitamin E(VE) and 100 mg/kg vitamin C(VC) were added to growing pig diet(containing VE 7 IU/kg) fed to female Duroc pigs(initial weights 46 kg) for 28 days.No improving effects in performance were found in contrast with which,25 IU/kg VE and 50 mg/kg VC were supplemented to finishing pig diet (containing VE 4.9 IU/kg).The average daily gain (ADG) in the pigs fed with VE and VC supplement diet was improved by 8.6%,and the feed to gain ratio was decreased by 11.7%.The results suggested that VE and VC level in the finishing pig diet should be higher than that in the growing pig diet for female Duroc pigs.
