有机砷制剂对生长肉猪发育的影响

Effects of Organic Arsenical Preparation on Devolopment for Growing pigs

将28 头体重在20kg 左右的长×荣仔猪随机分为两组。试验组在基础日粮中添加75mg/kg 的对氨基苯砷酸,对照组只喂基础日粮。经60 天试验结果表明,试验组平均日增重为729g,比对照组(667g) 高9-30 % ,差异显著(P< 0.05) ;饲料转化率分别为3-03 和3-21 ,提高5-94 % ;试验组猪皮肤红润光亮,腹泻率低;每千克增重需饲料成本,试验组比对照组少0-22 元,经济效益显著。

Landrace×Rongchang piglets weighted 20kg or so were randomly divided into 2 group A75mg/kg of arsanilic acid was added in the basal raation of the piglet in the treatment group while the piglets in the control group were fed the basal ration only.After 60 days' experimental stage the results showed:average daily gain of the piglet in the treatment group was 729g which was 9.30% significantly higher(P<0.05)than that of it the control group;(667g)the feed conversion rate was 3.03 and 3.21 respectively,i.e the fomer was 5.94% higher than the latter.The skins were ruddy and shiny and the incidence of diarrhea was lower in the piglet of treatment group.And the feed cost per kg body gain of the piglet in the treatment group was 0.22Yuan less than that of the control group,so the economic benefit was significant. \ \
