中草药添加剂对肉鸡及育肥猪的饲喂效果试验

为了探讨中草药添加剂对肉鸡和育肥猪生产性能的影响,试验选取同场同天入孵出壳的健康艾维茵健康肉仔鸡680只,自繁自养、日龄相同、体重接近的杜长大三元杂交育肥猪270头,分别随机分成5组,其中对照组1个,基础日粮中不添加中草药添加剂,试验组4个,分别添加不同水平中草药添加剂(肉鸡2.0%、2.5%、3.0%、3.5%,育肥猪0.40%、0.45%、0.50%、0.55%),测定生产性能等指标,分析肉鸡、育肥猪使用中草药添加剂的实际效果。结果表明:与对照组相比,饲料中使用中草药添加剂后,可明显提高肉鸡、育肥猪日增重、饲料报酬和经济效益,降低发病率和死亡率,并以肉鸡添加2.5%的中草药添加剂、育肥猪添加0.50%的中草药添加剂饲喂效果最好。说明中草药添加剂对肉鸡和育肥猪的生产性能具有良好的作用,可明显提高经济效益。

Experimental Study on Feeding Effect of Chinese HerbalMedicine Additive on Broiler and Fattening Pigs

In order to study the effects of Chinese herbal medicine additives on the production performance of broilers and fattening pigs,680 healthy Avian broilers hatched on the same day in the same field and 270 Duroc Landrace tri-breed Crossbred fattening pigs with the same age and similar body weight were selected,and were randomly divided into five groups.One control group,whose basic diet has no Chinese herbal medicine additives.Four experimental groups,the broilers and pigs in which were fed with Chinese herbal medicine additives in different proportions(2.0%,2.5%,3.0%,3.5%for broilers,0.40%,0.45%,0.50%,0.55%for fattening pigs)respectively in their basic diet.The production performance indexes were measured and the actual effects of using Chinese herbal medicine additives for broilers and fattening pigs were analyzed.The results showed as the followings:compared with the control group,the daily gain,feed reward and economic benefit for the broilers and fattening pigs could be significantly increased,and the morbidity and mortality could be reduced by adding Chinese herbal medicine additives in the feed.The best feeding effects were obtained in groups with 2.5%Chinese herbal medicine additives to broilers and 0.5%Chinese herbal medicine additives to fattening pigs.It was indicated that the additive of Chinese herbal medicine had a good effect on the performance of broiler and fattening pig,which could obviously improve the economic benefits.
