微生物发酵配合饲料对断奶仔猪生产性能的影响

试验选用25日龄体重相近、健康度良好的杜长大三元杂交断奶仔猪120头,随机分为3组,每组5个重复,每个重复8头猪(公母各半)。对照组为基础日粮+抗生素+酸化剂,试验1组为基础日粮+发酵剂A(1 kg/t)发酵,试验2组为基础日粮+发酵剂B(1 kg/t)发酵,旨在研究微生物发酵配合饲料对断奶仔猪生产性能的影响。结果表明,配合饲料添加微生态制剂发酵后,饲料pH值分别降低0.77和0.68(P<0.01)。与对照组相比,饲喂发酵配合饲料的2个试验组仔猪采食量有提高的趋势,腹泻率有降低的趋势,料重比有增加的趋势,但差异均未达到显著水平(P>0.05)。

Effects of microbial fermentation compound feed on production performance of weaning pigs

In order to study the effect of microbial fermentation compound feed on t production performance of weaning pigs,weaning pigs with similar weight and good health at the age of 25 days were randomly divided into 3 groups,with 5 replicates in each group and 8 pigs in each replicate(male and female half).The control group was fed with basal diet + antibiotic + acidifier, while the group 1 was fed with basal diet antibiotics acidifier+starter A(1 kg/T) and the group 2 was fed with basal diet antibiotics acidifier+starter B(1 kg/T).The results showed that the pH value of the feed decreased by 0.77 and 0.68 respectively(P<0.01) after adding microecological preparation to the compound feed.Compared with the control group,the feed intake and feed weight ratio of the two groups fed with fermented compound feed showed a trend of increase,while diarrhea rate showed a trend of decrease,but the difference was not significant(P>0.05).In conclusion,microbial fermented compound feed has good palatability and can improve intestinal health.
