【摘要】：试验旨在研究以苍术、黄柏和白术为主药的发酵复方中草药对断奶仔猪生长性能、免疫和生化指标影响。采用单因子试验,选取遗传背景相近、健康状况良好21日龄断奶仔猪(杜洛克×长白×大白)192头,随机分组Ⅰ(对照组,基础日粮)、Ⅱ(添加抗生素)、Ⅲ(添加0.20%未发酵复方中草药)、Ⅳ(添加0.10%发酵复方中草药)、Ⅴ(添加0.20%发酵复方中草药)、Ⅵ(添加0.30%发酵复方中草药组),每组4个重复,每个重复8头仔猪。试验期为28 d。结果表明,(1)断奶仔猪日粮中添加发酵和未发酵复方中草药,均可提高断奶仔猪平均日采食量和平均日增重,降低料重比和腹泻率。添加发酵复方中草药效果优于未发酵复方中草药,添加发酵复方中草药各组中,添加量0.20%时效果最好,其中,平均日采食量和日增重分别比对照组提高17.59%和30.51%(P0.05),与抗生素相比分别提高6.23%和9.05%(P0.05);料重比和腹泻率分别比对照组降低10.16%和48.38%(P0.05),与抗生素相比料重比降低3.09%、腹泻率提高19.12%(P0.05);(2)添加未发酵复方中草药组仔猪免疫力与对照组相比差异不显著(P0.05),添加发酵复方中草药组中以添加0.2%组效果最好,可显著提高断奶仔猪血清中Ig A、Ig G、Ig M、TP和GH含量,与对照组相比,分别提高9.72%、15.88%、7.43%、20.66%、37.24%(P0.05),血清中CHOL含量与对照组相比显著降低16.06%(P0.05)。综上所述,在断奶仔猪日粮中添加发酵复方中草药可提高断奶仔猪生长性能,增强仔猪免疫力,为发酵中草药饲料添加剂替代抗生素类药物在仔猪生产中应用提供参考。
[Abstract]:The experiment was conducted to study the effects of fermented Chinese herbal medicine on growth performance, immunity and biochemical indexes of weaned piglets. 192 21-day-old weaned piglets with similar genetic background and good health were selected by single factor test. They were randomly divided into two groups, i.e. control group, basic diet, and ii. Adding antibiotics, adding 0.20% unfermented Chinese herbal medicine, IV (adding 0.10% fermented Chinese herbal medicine), V (adding 0.20% fermented Chinese herbal medicine), VI (adding 0.30% fermented Chinese herbal medicine), 4 replicates in each group, 8 piglets in each replicate. The experimental period was 28 days. The results showed that: (1) adding fermented and unfermented Chinese herbal medicine in the diet of weaned piglets. The effect of adding fermented compound Chinese herbal medicine was better than that of unfermented compound Chinese herbal medicine. The effect of adding 0.20% fermented compound Chinese herbal medicine was the best, and the average daily feed intake and daily gain were increased by 17.59% and 30.59% respectively. 51% (P 0.05), 6.23% and 9.05% (P 0.05), feed weight ratio and diarrhea rate were decreased by 10.16% and 48.38% (P 0.05), 3.09% and 19.12% (P 0.05) respectively, compared with antibiotics. (2) The immunity of piglets with unfermented compound Chinese herbal medicine was not significantly different from that of control group (P 0.05). Compared with the control group, the contents of Ig A, Ig G, Ig M, TP and GH in the serum of weaned piglets were increased by 9.72%, 15.88%, 7.43%, 20.66%, 37.24%(P 0.05), and the content of CHOL in the serum was significantly decreased by 16.06%(P 0.05). Fermented compound Chinese herbal medicine can improve the growth performance of weaned piglets and enhance the immunity of piglets.
