中草药与抗生素作为添加剂对本地鸡生产性能的影响

本试验对本地鸡设计了A、B、C、D四种饲料进行饲养试验,结果表明:A组(混合型基础日粮+中草药添加剂)平均日增重比B组(混合型基础日粮+抗生素添加剂)、C组(玉米型基础日粮+中草药添加剂)、D组(玉米型基础日粮+抗生素添加剂)分别提高20.03%、18.3%、46.8%,与B、C组之间差异显著(P<0.05),与D组之间差异极显著(P<0.01)。经济效益以A组最好,比B、C、D组分别提高26.37%、26.05%、59.75%。平均采食量A组比B、C、D组分别提高1.20%、0.87%、9.87%。A、B组比C、D组平均日增重提高19.94%,差异显著(P<0.05),经济效益提高26.04%。A、C组比B、D组平均日增重提高22.04%,差异显著(P<0.05),经济效益提高22.67%。因此,用稻米来代替部份玉米,用中草药添加剂代替抗生素添加剂是可行的,且能获得较好的日增重和经济效益。

The Influence of Chinese Herbal Medicine and Antibiotic as Additives onThe production Function of Local Chickens

The experiment designs four kinds of feed named A,B,C and D for local chi ckens,and it turns out that group A' s everyday increase in weight in averag e is20.03%?18.30%and46.80%higher.Than group B,C and D.The difference between group A and group B,C is marked(p <0.05),and especia lly the difference between group A and group D(p<0.01).The economic bene fits of group A is best,and it is26.37%,26.05%and59.75%highe r than group B,CandD.Eating feed in average is1.20%,0.87%,9.87 %higher than group B,C and D.GroupAandB' s everyday increasein wei ghtin aver age is19.94%,higher than group C and D,and the difference is marked,and the economic benefits increase26.04%.Group A and C's everyday increase in weightin average is22.04%higher than group B and D,and the difference is marked(p<0.05),and the economic benefits increase22.67%.Sowe come to the conclusion thatitis feasible to use rice instead of corn,and to use Chinese herbal additives instead of antibiotic additives to feed chickens,and the economic benefits is also better.
