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(P〈0.05),与HMCS组差异不显著(P〉0.05);MR处理组犊牛血清中一氧化氮含量显著高于CS组(P〈0.05),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(P〉0.05),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(P〈0.05),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(P〈0.05)。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(P〉0.05),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。 The objective of this study was to investigate the effects of the mixture of steam-flaked corn and extruded soybeans on diarrhea and blood parameters in veal calves. Calves (n = 39) were randomly divided into three treatment groups with 13 calves in each group:Group 1,milk replacer (MR) group;Group 2,half of the amount of MR in treatment one plus other half of mixture of steam-flaked corn and extruded soybeans (HMCS) ;Group 3, mixture of steam-flaked corn and extruded soybeans (CS). All the calves were fed for 150 d, and their diarrhea and blood parameters were studied. The results showed that:Calves fed CS had the lowest incidence of diarrhea (1.03%) that calves fed HMCS (15. 13%) and CS (59.74%);Compared to calves in HMCS and MR treatments, calves in CS treatment had the greatest activities of Catalase, GSH-PX, TAC; MR calves had the greatest values of MDA than HMCS and CS calves;Calves fed with MR had the greatest values of NO than in calves fed with CS,with HMCS calves taking the intermediate value;Calves fed with MR had the greatest values of Cholesterol than calves fed with CS. However,CS calves had the greatest values of serum urea nitrogen, total protein, and INS than MR calves; Compared to HMCS and MR calves, calves fed with CS had the greatest activities of GOP and GP-r; The values of IgM in CS calves was greatest than in other calves. These data suggested that a mixture of steam-flaked corn and extruded soybeans provided ad libitum in better animal feed for improving blood antioxidant,immunity,and positively contributes to blood biochemistry indexes in veal calves.
