为研究不同水平的中草药添加剂对断奶仔猪生长性能、血清生化指标及免疫指标的影响,试验采用单因素随机设计,选择体重相近的28日龄"杜×长×大"三元杂交断奶仔猪80头随机分成4组,每组20个重复,每个重复1头,1组为对照组饲喂基础日粮,试验2、3、4组在基础日粮中分别添加0.5、1.0、1.5 g/kg的中草药添加剂,试验期为28 d。结果表明:(1)试验3、4组的平均日增重较1组比分别提高8.6%、7.9%(P<0.05),料重比较1组比分别降低12.4%、10.8%(P<0.05),试验2、3、4组的平均日采食量均高于1组(P>0.05);(2)试验3、4组血清中的总蛋白(TP)含量均较1组比分别提高19.8%、21.0%(P<0.05),血清中尿素氮(BUN)含量较1组比分别降低16.9%、12.9%(P<0.05),试验2、3、4组血清中的谷氨酸氨基转移酶(GPT)、天门冬氨酸氨基转移酶(GOT)含量均低于1组(P>0.05),试验2、3、4组血清中白蛋白(ALB)含量均高于1组(P>0.05);(3)试验3、4组血清中的IgG、IL-2含量较1组分别提高17.2%、18.8%、22.0%、21.7%(P<0.05),试验2、3、4组血清中的IgM、IgA、IL-6含量均高于1组(P>0.05)。综上所述,中草药添加剂可以提高断奶仔猪的生长性能、肝肾代谢水平及免疫机能,以1.5 g/kg为适宜。
In order to study the effects of different levels of traditional Chinese medicine additives on growth performance,serum biochemical indexes and immune indexes of weaned piglets. In the experiment,80 piglets of 28 day old "Du ×Chang ×Da" with similar body weight were randomly divided into 4 groups,20 replicates in each group, 1 in each replicate. One group was the control group and fed with basic diet. In the experiment 2,3 and 4 groups,0.5,1.0,1.5 g/kg traditional Chinese medicine additives were added respectively. The experimental period was 28 days.The results showed that :(1) The average daily gain of groups 3 and 4 were 8.6% and 7.9% higher than that of group 1 respectively(P<0.05),the feed weight of groups 3 and 4 were 12.4% and 10.8% lower than that of group 1 respectively(P<0.05),the average daily intake of groups 2,3 and 4 were higher than that of group 1(P>0.05);(2) The total protein(TP) content of blood serum in groups 3 and 4 were 19.8% and 21.0% higher than that of group 1 respectively(P<0.05),and the urea nitrogen(BUN) content in serum were 16.9% and 12.9% lower than that of group 1 respectively(P<0.05),the content of glutamate aninotransferase(GPT) and aspartate aminotransferase(GOT) in the serum of groups 2,3 and 4 were lower than that of group 1(P>0.05),the content of albumin(ALB) in the serum of groups 2,3 and 4 were 17.2%,18.8%,22.0% and 21.7% higher than that of group 1(P>0.05);(3)The content of IgG and IL-2 in the serum of groups 3 and 4 were higher than that of group 1(P<0.05),the content of IgM,IgA and IL-6 in the serum of groups 2,3 and 4 were higher than that of group 1(P>0.05).In conclusion,1.5 g/kg of traditional Chinese medicine additive could improve the growth performance,liver and kidney metabolism level and immune function of weaned piglets.
