中草药制剂对断奶仔猪生长性能、血清生化和免疫的影响

文章旨在评估日粮添加中草药添加剂对断奶仔猪生长性能、血清生化和免疫指标的影响。试验选择21d断奶、平均体重为(5.90±0.03)kg的仔猪450头,随机分为3组,每组5个重复,每个重复30头。对照组饲喂基础日粮,抗菌肽组饲喂基础日粮+45mg/kg抗菌肽,中草药组饲喂基础日粮+200mg/kg中草药添加剂,试验共进行42d。结果:对照组断奶仔猪在1~21d日增重较其他两组分别显著降低3.57%和5.86%(P<0.05),而中草药组仔猪在22~42d的日增重较对照组和抗菌肽组分别显著提高3.64%和3.37%(P<0.05),同时该组1~42d日增重较对照组显著提高4.54%(P<0.05)。与对照组相比,中草药组仔猪在1~21d和1~42d的料重比分别显著降低5.52%和3.47%(P<0.05)。对照组仔猪死亡率较其他两组分别显著提高137.75%和126.21%(P<0.05)。中草药组仔猪血清胆固醇含量较对照组和抗菌肽组分别显著降低35.78%和33.43%(P<0.05),但该组血清甘油三酯浓度分别显著提高19.09%和11.96%(P<0.05)。中草药组仔猪血清IgG浓度较对照组显著提高12.74%(P<0.05),而对照组和中草药组血清IL-6浓度较抗菌肽组分别显著提高34.04%和23.89%(P<0.05)。结论:在本试验条件下,日粮添加200mg/kg中草药添加剂可以改善断奶仔猪生长性能、血清性状及免疫反应。

Effects of Chinese herbal medicine on growth performance serum biochemistryand immunity of weaned piglets

The aim of this study was to evaluate the effects of dietary herbal supplements on growth performance,serum biochemical and immune indices of weaned piglets.450 piglets weaned at 21 days and with an average weight of(5.90±0.03)kg were randomly divided into 3 groups with 5 replicates in each group and 30 piglets in each replicate.The control group was fed a basic diet,the antimicrobial peptide group was fed a basic diet+45 mg/kg antimicrobial peptide,and the Chinese herbal medicine group was fed a basic diet+200 mg/kg Chinese herbal medicine additive.The experiment was conducted for 42 days in total.Results:The daily weight gain of weaned piglets in the control group was 3.57%and 5.86%lower than that of the other two groups on day 1~21(P<0.05),while the daily weight gain of weaned piglets in the Chinese herbal medicine group was 3.64%higher than that of the control group and 3.37%higher than that of the antibacterial peptide group on day 22~42(P<0.05),and the daily weight gain of weaned piglets in the Chinese herbal medicine group was 4.54%higher than that of the control group on day 1~42(P<0.05).Compared with the control group,the feed weight ratio of piglets in the Chinese herbal medicine group was significantly reduced by 5.52%and 3.47%at 1~21 and 1~42 days,respectively(P<0.05).Compared with the other two groups,the mortality of piglets in the control group was significantly increased by 137.75%and 126.21%,respectively(P<0.05).Compared with the control group and the antimicrobial peptide group,the serum cholesterol content of piglets in the Chinese herbal medicine group was significantly reduced by 35.78%and 33.43%,respectively(P<0.05),while the serum triglyceride concentration of piglets in the Chinese herbal medicine group was significantly increased by 19.09%and 11.96%,respectively(P<0.05).The serum IgG concentration of piglets in the Chinese herbal medicine group was significantly increased by 12.74%compared with the control group(P<0.05),while the serum IL~6 concentration in the control group and the Chinese herbal medicine group was significantly increased by 34.04%and 23.89%compared with the antimicrobial peptide group(P<0.05).Conclusion:Adding 200 mg/kg of Chinese herbal medicine to the diet can improve the growth performance,serum character and immune response of weaned piglets.
