【摘要】：試驗(yàn)旨在研究以蒼術(shù)、黃柏和白術(shù)為主藥的發(fā)酵復(fù)方中草藥對(duì)斷奶仔豬生長(zhǎng)性能、免疫和生化指標(biāo)影響。采用單因子試驗(yàn),選取遺傳背景相近、健康狀況良好21日齡斷奶仔豬(杜洛克×長(zhǎng)白×大白)192頭,隨機(jī)分組Ⅰ(對(duì)照組,基礎(chǔ)日糧)、Ⅱ(添加抗生素)、Ⅲ(添加0.20%未發(fā)酵復(fù)方中草藥)、Ⅳ(添加0.10%發(fā)酵復(fù)方中草藥)、Ⅴ(添加0.20%發(fā)酵復(fù)方中草藥)、Ⅵ(添加0.30%發(fā)酵復(fù)方中草藥組),每組4個(gè)重復(fù),每個(gè)重復(fù)8頭仔豬。試驗(yàn)期為28 d。結(jié)果表明,(1)斷奶仔豬日糧中添加發(fā)酵和未發(fā)酵復(fù)方中草藥,均可提高斷奶仔豬平均日采食量和平均日增重,降低料重比和腹瀉率。添加發(fā)酵復(fù)方中草藥效果優(yōu)于未發(fā)酵復(fù)方中草藥,添加發(fā)酵復(fù)方中草藥各組中,添加量0.20%時(shí)效果最好,其中,平均日采食量和日增重分別比對(duì)照組提高17.59%和30.51%(P0.05),與抗生素相比分別提高6.23%和9.05%(P0.05);料重比和腹瀉率分別比對(duì)照組降低10.16%和48.38%(P0.05),與抗生素相比料重比降低3.09%、腹瀉率提高19.12%(P0.05);(2)添加未發(fā)酵復(fù)方中草藥組仔豬免疫力與對(duì)照組相比差異不顯著(P0.05),添加發(fā)酵復(fù)方中草藥組中以添加0.2%組效果最好,可顯著提高斷奶仔豬血清中Ig A、Ig G、Ig M、TP和GH含量,與對(duì)照組相比,分別提高9.72%、15.88%、7.43%、20.66%、37.24%(P0.05),血清中CHOL含量與對(duì)照組相比顯著降低16.06%(P0.05)。綜上所述,在斷奶仔豬日糧中添加發(fā)酵復(fù)方中草藥可提高斷奶仔豬生長(zhǎng)性能,增強(qiáng)仔豬免疫力,為發(fā)酵中草藥飼料添加劑替代抗生素類(lèi)藥物在仔豬生產(chǎn)中應(yīng)用提供參考。
[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.
