【摘要】：本試驗(yàn)旨在研究中草藥添加劑在斷奶仔豬生產(chǎn)中應(yīng)用效果及機(jī)理研究。中草藥添加劑由藿香、紫蘇、白芷、厚樸等組成。本試驗(yàn)采用完全隨機(jī)設(shè)計(jì),選取100頭"杜洛克×長(zhǎng)白×大白"三元雜交斷奶仔豬,隨機(jī)分成五組,第1組是基礎(chǔ)日糧組,第2組、第3組、第4組分別在基礎(chǔ)日糧中添加0.05%、0.1%、0.15%的中草藥添加劑,第5組在基礎(chǔ)日糧中添加30mg/kg的硫酸粘菌素。通過測(cè)定斷奶仔豬生長(zhǎng)性能、血液生化指標(biāo)、糞中指標(biāo),確定中草藥添加劑的作用效果、最宜添加量及作用機(jī)理。結(jié)果表明:(1)中草藥添加劑提高了斷奶仔豬的生產(chǎn)性能。0.1%中草藥組和硫酸粘菌素組顯著提高了試驗(yàn)各期斷奶仔豬的平均日增重(P0.05),顯著降低了試驗(yàn)后期和試驗(yàn)全期的料重比(P0.05),極顯著的降低斷奶仔豬的腹瀉率(P0.01),但0.1%中草藥的效果更佳。(2)中草藥添加劑提高了斷奶仔豬的免疫性能。各中草藥組顯著提高了 14天免疫球蛋白A的含量和28天白介素6的含量(P0.05),顯著提高了兩次取樣白介素10和一氧化氮的含量(P0.05),0.1%、0.15%中草藥組極顯著的提高了 28天免疫球蛋白A的含量(P0.01),0.1%、0.15%中草藥組兩次取樣均顯著提高了補(bǔ)體C4的含量(P0.05)。其中0.1%中草藥組比對(duì)照組提高的更多。(3)中草藥添加劑降低了斷奶仔豬的應(yīng)激水平。各中草藥組顯著降低了 14天肌酸激酶的含量(P0.05),極顯著的降低了 28天肌酸激酶的含量(P0.01),顯著降低了 28天生長(zhǎng)抑素的含量(P0.05),0.1%、0.15%中草藥組兩次取樣均顯著的降低了乳酸脫氫酶的含量(P0.05)。(4)中草藥添加劑促進(jìn)了斷奶仔豬體內(nèi)的蛋白合成。0.1%、0.15%中草藥組顯著提高了 28天總蛋白的含量(P0.05),顯著提高了兩次取樣白蛋白和球蛋白的含量(P0.05),顯著降低了 14天尿素氮的含量(PP0.05),各中草藥組極顯著降低了 28天尿素氮的含量(P0.01)。(5)中草藥添加劑促進(jìn)了斷奶仔豬的微生物平衡。各中草藥組顯著的降低了 14、28天糞中大腸桿菌的數(shù)量(P0.05),顯著的提高了 28天糞中雙歧桿菌的數(shù)量(P0.05),極顯著的增加了 28天糞中乳酸桿菌的數(shù)量(P0.01)。本試驗(yàn)中,中草藥添加劑和硫酸粘菌素均能對(duì)斷奶仔豬的生產(chǎn)性能、免疫性能和菌群平衡產(chǎn)生積極的作用。其中中草藥添加劑的最優(yōu)添加量為0.1%,對(duì)各項(xiàng)指標(biāo)的作用也優(yōu)于硫酸粘菌素。
[Abstract]:The purpose of this study was to study the effect and mechanism of Chinese herbal medicine additives in weanling pig production. Chinese herbal medicine additives are made up of Herba Herba, perilla, Radix Angelicae and Magnolia officinalis. This experiment was completely randomized design, selection of 100 "Duroc * Landrace * large white three crossbred weaned piglets were randomly divided into five groups, the first group is the basal diet group, Chinese herbal medicine group second, group third, fourth groups of 0.05%, 0.1% and 0.15% were added in the basic diet, the fifth group added to the diets of 30mg/kg in polymyxin sulfate. By measuring the growth performance of weaned piglets, the biochemical indexes of blood, and the index of feces, the effect, the optimum amount and the mechanism of the addition of Chinese herbal medicine were determined. The results showed that: (1) the Chinese herbal medicine additive improved the production performance of weanling piglets. 0.1% Chinese herbal medicine group and colistin group significantly increased the average daily gain (P0.05) of weaned piglets in each trial period, significantly reduced the feed to weight ratio (P0.05) at the end of the trial and the whole trial period, and significantly reduced the diarrhea rate of weaned piglets (P0.01), but the effect of 0.1% Chinese herbal medicine was better. (2) the Chinese herbal additive can improve the immune performance of weanling piglets. The Chinese herbal medicine group significantly increased the content of immunoglobulin A in 14 days and 28 days of interleukin 6 (P0.05), significantly increased the contents of two samples of interleukin 10 and nitric oxide (P0.05), 0.1%, 0.15% Chinese herbal medicine group significantly improved the content of the 28 day of immunoglobulin A (P0.01 0.1%, 0.15%), Chinese herbal medicine group two samples significantly increased the content of complement C4 (P0.05). 0.1% of the Chinese herbal medicine group increased more than the control group. (3) the Chinese herbal additive reduces the stress level of weanling piglets. The Chinese herbal medicine group decreased 14 days creatine kinase (P0.05), significantly reduced the content of 28 days of creatine kinase (P0.01), decreased the content of 28 days of somatostatin (P0.05), 0.1%, 0.15% Chinese herbal medicine group two samples significantly decreased the content of lactate dehydrogenase. (P0.05). (4) the Chinese herbal medicine additive promotes the protein synthesis in weanling piglets. Chinese herbal medicine group 0.1%, 0.15% and 28 days significantly increased the contents of total protein (P0.05), significantly increased the contents of two samples of albumin and globulin (P0.05), decreased the content of urea nitrogen in 14 days (PP0.05), the Chinese herbal medicine group significantly decreased the content of urea nitrogen (28 days P0.01). (5) the Chinese herbal additive promoted the microbial balance of weanling piglets. The Chinese herbal medicine group significantly reduced the number of Escherichia coli in feces (P0.05), which significantly increased the number of bifidobacteria in feces (P0.05) for 14 days and 28 days, and significantly increased the number of lactobacilli in feces 28 days (P0.01). In this experiment, both Chinese herbal medicine and colysin sulfate can play a positive role in the production performance, immune performance and bacterial balance of weanling piglets. The optimum addition of Chinese herbal medicine additive was 0.1%, and the effect on various indexes was better than that of clay colysin.
