日粮中添加酸化剂对断乳仔猪生长性能的影响

Effect of supplemention with acidulant on performance in weaned piglets

选取128头7～8kg左右"杜长大"健康断乳仔猪作为试验动物,根据体重相近、公母各半的原则将其随机分为对照组和试验组,每个组设4个重复,每个重复16头,探讨添加酸化剂对仔猪生长性能和腹泻率的影响。结果表明,试验组日粮中添加2g/kg的酸化剂,提高了仔猪的日增重,降低了料重比,但差异不显著(P>0.05);减少了仔猪的腹泻率,并可降低饲料成本。

128 weaning piglets （Duroc xLandracexYorkshire） about 7-8 kg were divided randomly into control group and trial group by sex and weight to study the effects of supplemention with 2 g/kg acidulant on performance and diarrhea frequency in piglets. Each group had four repeats with sixteen piglets. Daily gain and feed conversion efficiency were increased by supplementing with acidulant, but no significant differences were observed （P〉0.05）. Diarrhea frequency and feed cost were reduced by supplementing with acidulant.The results indicated that the performance and economic benefit were improved.
