【摘要】：为研究蒸汽压片玉米及膨化大豆混合日粮对荷斯坦公犊牛腹泻情况、血液生理、生化指标的影响,选择39头荷斯坦公犊牛随机分为3组,分别饲喂代乳粉(MR)、一半代乳粉+蒸汽压片玉米与膨化大豆的混合精料(HMCS)、蒸汽压片玉米与膨化大豆的混合精料(CS),饲养150d,记录犊牛腹泻情况,测定犊牛血液指标。研究发现,MR组的腹泻情况最为严重,腹泻指数为59.74%,其次是HMCS组,为15.13%,CS组最低,为1.03%;犊牛血液抗氧化指标表现为,CS组犊牛的过氧化氢酶、谷光氨肽过氧化物酶、总抗氧化能力均是最高。MR组丙二醛的含量显著高于CS组(P0.05),与HMCS组差异不显著(P0.05);MR处理组犊牛血清中一氧化氮含量显著高于CS组(P0.05),HMCS组的含量处于二者之间;血细胞分析结果为3个处理的白细胞、嗜中性粒细胞、淋巴细胞及单核细胞差异均不显著(P0.05),但CS组犊牛的白细胞数、淋巴细胞及单核细胞数在数值上均是最高;血清生化指标结果为,MR处理组犊牛血清的总胆固醇含量显著高于CS组(P0.05),而CS组犊牛血清的尿素氮、总蛋白及胰岛素含量显著高于MR组。CS组的谷草转氨酶活性、谷丙转氨酶的活性最高;CS组的IgM浓度显著高于另外2组(P0.05)。低密度脂蛋白、极低密度脂蛋白及高密度脂蛋白的含量在3个处理间差异不显著(P0.05),但CS组的数值均是最高的。研究表明蒸汽压片玉米及膨化大豆可以减少犊牛腹泻发生,提高犊牛血液抗氧化和免疫水平,并促进血液总蛋白合成。
[Abstract]:In order to study the effects of steam pressed corn and expanded soybean mixed diet on diarrhea, blood physiology and biochemical indexes of Holstein male calves, 39 Holstein male calves were randomly divided into 3 groups. The mixture concentrate of steam pressed corn and extruded soybean were fed with MRA, and the mixed concentrate of steam pressed corn and expanded soybean were fed with CSC for 150 days, and the diarrhea of calves was recorded. The results showed that the diarrhea index was 59.74 in Mr group, the lowest in HMCS group, 1.033 in CS group, and catalase in calves in CS group. The content of malondialdehyde in group Mr was significantly higher than that in group C (P 0.05), but the content of no in serum of calves treated with HMCS was significantly higher than that in group C (P 0.05). The results of blood cell analysis showed that there was no significant difference in white blood cells, neutrophils, lymphocytes and monocytes among the three treatments, but the number of white blood cells, lymphocytes and monocytes in CS group was the highest. The results of serum biochemical indexes showed that the serum total cholesterol content of calves treated with Mr was significantly higher than that of CS group (P 0.05), while the contents of urea nitrogen, total protein and insulin in serum of CS group were significantly higher than those of Mr group and CS group, and the activity of glutamic oxaloacetic transaminase was significantly higher than that of CS group. The concentration of IgM in the group with the highest activity of glutamate-pyruvic transaminase was significantly higher than that in the other two groups. The contents of very low density lipoprotein and high density lipoprotein were not significantly different among the three treatments, but the values of CS group were the highest. To improve the blood antioxidant and immune levels of calves, and promote the synthesis of total blood protein.
