摘要
试验旨在研究发酵北苍术对断奶仔猪血清免疫指标和生化指标的影响。选取96头体况相近、断奶重为(6.0±0.5)kg的长白猪×大白猪二元杂交仔猪,随机分为6组,每组4个重复,每个重复4头猪。对照组饲喂基础日粮,Ⅰ组为抗生素组,在基础日粮中添加杆菌肽锌+硫酸黏杆菌素,Ⅱ组在基础日粮中添加0.2%未发酵北苍术,Ⅲ、Ⅳ、Ⅴ组分别在基础日粮中添加0.1%、0.2%、0.3%发酵北苍术,试验期为28d。结果显示,日粮中添加发酵北苍术组的断奶仔猪的血清各项免疫指标和生化指标较对照组及Ⅰ组均有不同程度的改善,其中Ⅳ组的效果最好。在整个试验阶段(断奶后28d),与对照组相比,Ⅳ组断奶仔猪血清中IgA、IgG、IgM、TP和ALB含量分别提高了10.5%、10.0%、7.8%、21.0%和15.6%,差异均显著(P<0.05),血清中ALT含量与对照组相比显著降低了20.4%(P<0.05);与Ⅰ组相比,Ⅳ组断奶仔猪血清中IgA、IgG、IgM、TP分别提高了7.1%、3.8%、3.8%、12.6%,差异均显著(P<0.05),而ALB、AST和BUN含量分别提高了1.0%、9.5%和15.0%,差异均不显著(P>0.05),血清中ALT含量与Ⅰ组相比降低了9.4%(P>0.05)。
The aim of this experiment was conducted to study the effects of fermented Atractylodes chinensis on serum immune and biochemical indexes of weaned piglets.Ninety-six Landrace ×Large White weaned piglets with weaning weight（6.0±0.5）kg were randomly allocated to 6groups with 4replicates per group and 4weaned piglets per replicate.The weaned piglets were subjected to the following 6treatments for 28days：Control group was fed with the basal diet,groupsⅠandⅡwere fed with antibiotics and 0.2% unfermented Atractylodeschinensisin basal diet,while groupsⅢ,ⅣandⅤ were supplemented 0.1%,0.2%and 0.3%fermentated Atractylodes chinensis in basal diet,respectively.The results showed that the immune and biochemical index of weaned piglets in fermented Atractylodes chinensis group had different degrees of improvement compared with control group and groupⅠ.In the whole experimental stage,comparing with control group,the serum IgA,IgG,IgM,TP and ALB of weaned piglets in groupⅣ were increased 10.5%,10.0%,7.8%,21.0% and 15.6%,respectively,and the difference were significant（P〈0.05）,and serum ALT content was significantly reduced 20.4%（P〈0.05）.Compared with groupⅠ,the serum IgA,IgG,IgM and TP of weaned piglets in groupⅣ were increased7.1%,3.8%,3.8%and 12.6%,respectively,the difference were significant（P〈0.05）,while the ser-um ALB,AST and BUN of groupⅣ were increased 1.0%,9.5%and 15.0%,and the difference were not significant（P〈0.05）,and serum ALT content was reduced 9.4% compared with the antibiotics group（P〈0.05）.
