【摘要】：試驗目的是探討不同水平酵母培養(yǎng)物對保育仔豬生長性能和血液免疫指標的影響。選取120頭28 d斷奶仔豬,隨機分成3個處理組:對照組、0.5%酵母培養(yǎng)物組、1%酵母培養(yǎng)物組。測定和計算試驗第14 d和37 d仔豬的生長性能和血清生化指標。試驗結果表明,0.5%和1%酵母培養(yǎng)物組顯著提高了保育仔豬平均日增重,減少了平均日采食量,改善了料肉比。在試驗第14 d,1%酵母培養(yǎng)物組顯著提高了血液中總補體(CH50)和白介素2(IL-2)水平,極顯著提高了紅細胞水平,顯著降低了內(nèi)毒素(ET)水平;0.5%和1%酵母培養(yǎng)物組顯著提高了血紅蛋白水平;0.5%酵母培養(yǎng)物組顯著降低了血小板水平。在試驗第37 d,1%酵母培養(yǎng)物組極顯著提高了紅細胞、免疫球蛋白(Ig G)和IL-2水平,極顯著降低了ET水平,顯著提高了CH50水平;0.5%和1%酵母培養(yǎng)物組極顯著提高了白細胞和淋巴細胞水平,極顯著降低了血小板水平;0.5%酵母培養(yǎng)物組極顯著提高了紅細胞水平。以上結果表明,日糧中添加酵母培養(yǎng)物改善了保育仔豬的生長性能,添加量0.5%和1%酵母培養(yǎng)物的效果相當;酵母培養(yǎng)物提高了仔豬的免疫系統(tǒng)的應答能力,添加1%酵母培養(yǎng)物的免疫保護作用要好于添加0.5%。
[Abstract]:The aim of this study was to investigate the effects of yeast cultures at different levels on growth performance and blood immunity of piglets.120 28 d weaned piglets were randomly divided into 3 groups: control group (0.5% yeast culture) and 1% yeast culture group.The growth performance and serum biochemical indexes of piglets on the 14th and 37th day of the experiment were measured and calculated.The results showed that 0.5% and 1% yeast culture significantly increased the average daily gain, reduced the average daily intake and improved the feed / meat ratio.On the 14th day, the 1% yeast culture group significantly increased the levels of total complement CH50) and interleukin 2 (IL 2), and increased the level of red blood cell (RBC) significantly.The levels of endotoxin et (0.5%) and 1% yeast culture significantly increased the hemoglobin level. The 0.5% yeast culture group significantly decreased the platelet level.The levels of erythrocyte, immunoglobulin G) and IL-2 were significantly increased in the 1% yeast culture group on the 37th day of the experiment, and the levels of et were significantly decreased in the 1% yeast culture group on the 37th day of the experiment.The levels of CH50 were significantly increased in 0.5% and 1% yeast cultures, and the levels of leukocytes and lymphocytes were significantly increased in the yeast culture group, and the platelet level was significantly decreased in the yeast culture group, and the erythrocyte level was significantly increased in the yeast culture group (0.5%).The results showed that the growth performance of piglets was improved by adding yeast culture to the diet, the effect of 0.5% and 1% yeast culture was the same, and the immune response ability of piglets was improved by yeast culture.The immune protection of 1% yeast culture was better than that of 0.5% yeast culture.
