摘要 为了验证市售的不同酸化剂对断奶仔猪生长性能和营养表观消化率的影响,试验选取38日龄、体重10 kg左右的断奶仔猪150头,随机分为5个处理组,每个处理组6个重复,每个重复5头,分别在日粮中添加0.4%的不同酸化剂(酸化剂A、酸化剂B、酸化剂C和酸化剂D),测定断奶仔猪生长性能指标,分析不同酸化剂对断奶仔猪生长性能及营养表观消化率的影响。结果表明:与对照组相比,试验1组、试验2组、试验3组、试验4组的料重比分别降低了9.36%、1.75%、8.77%和6.43%,且试验1、3组差异显著(P<0.05);腹泻率分别降低了24.66%、4.48%、39.46%和39.91%,且试验1、3、4组差异显著(P<0.05);粗脂肪表观消化率提高了25.99%、20.00%、12.12%和15.94%,且差异显著(P<0.05)。说明在断奶仔猪常规日粮中添加酸化剂能显著降低仔猪的腹泻率,提高生长性能,改善料重比,提高营养表观消化率,不同的酸化剂效果差异较明显。 In order to verify the effects of different acidifiers on the growth performance and apparent digestibility of nutrients of weaned piglets,150 weaned piglets aged 38 days and weighing about 10 kg were randomly divided into five treatment groups with six replicates per treatment group and five piglets per replicate.Four acidifiers(Acidifier A,Acidifier B,Acidifier C and Acidifier D)of 0.4% were added to the diet,respectively,and the growth performance indexes of weaned piglets were determined to verify their effects on the growth performance of weaned piglets.The results showed that compared with the control group,the feed-gain ratios of the test groups 1,2,3 and 4 decreased by 9.36%,1.75%,8.77% and 6.43% with significant differneces between group 1,3 and control group(P<0.05),respectively,and the diarrhea rate decreased by 24.66%,4.48%,39.46% and 39.91% with significant differences between group 1,3,4 and control group(P<0.05),respectively.The apparent digestibility of crude fat increased by 25.99%,20.00%,12.12% and 15.94% with significant differences between four test groups and control group(P<0.05),respectively.Acidifiers added in the conventional diet of weaned piglets could significantly reduce the diarrhea rate,improve the growth performance,reduce the feed-gain ratio of weaned piglets,and improve the apparent digestibility of nutrients.The effects of several acidifiers were obviously different.
