摘要: 本试验旨在研究复合水溶性维生素对春、夏季奶牛生产性能、血液生理生化指标和抗氧化性能的影响。采用2×2因子随机区组设计,选取胎次、体重相近的健康成年奶牛80头,随机分为4个处理,即Ⅰ、Ⅱ、Ⅲ、Ⅳ组,4组均饲喂基础日粮,Ⅲ、Ⅳ处理在春季补充复合水溶性维生素,Ⅱ、Ⅳ处理组在夏季补充复合水溶性维生素,各组添加量均为0.02%(日粮干物质为基础),预试期7 d,正式期70 d。结果表明:在春季添加复合水溶性维生素极显著提高奶牛的平均日采食量和日产奶量(P<0.01);在夏季显著提高奶牛的平均日采食量(P<0.05),极显著提高日产奶量(P<0.01);均能极显著提高乳脂率(P<0.01),极显著降低体细胞数(P<0.01);均能显著影响淋巴细胞总数(P<0.05)。在夏季补充复合水溶性维生素能极显著增加血清总抗氧化能力、总超氧化物歧化酶(P<0.01),极显著降低乳酸脱氢酶、白蛋白、总蛋白、高密度脂蛋白、低密度脂蛋白和磷酸肌酸激酶含量(P<0.01)。综上所述,复合水溶性维生素可以提高奶牛的生产性能,增强奶牛非特异性免疫,改善奶牛抗氧化性能,减少夏季热应激。

Abstract: The objective of the study was to investigate the effects of supplemental complex water soluble vitamins on production performance, blood biochemical parameters and oxidative resistance of dairy cows in spring and summer.The experiment was designed by 2×2 factorial randomized blocks design.Eighty healthy dairy cows with similar parity and body weight were randomly divided to four groups, with 7 days of adaptation and 70 d experimental phase.The dairy cows in group Ⅲ and Ⅳ were fed a basal diet supplemented with complex water soluble vitamins in spring.The dairy cows in group Ⅱ and Ⅳ were fed a basal diet supplemented with complex water soluble vitamins in summer.The results showed that the ADFI and daily milk yield of dairy cows receiving water soluble vitamin in spring were extremely significantly higher (P<0.01);The ADFI of dairy cows receiving water soluble vitamin was significantly higher in summer (P<0.05) and daily milk yield were extremely significantly higher (P<0.01);The butterfat rate was extremely significantly increased and SCC was extremely significantly decreased in spring and summer (P<0.01);Supplementation of water soluble vitamin was also significantly increased LYM (P<0.05).In summer, T-AOC, T-SOD were extremely significantly increased (P<0.01), and TP, CK, LDH, TP, HDL and ALB were extremely significantly decreased (P<0.01) by water soluble vitamin supplementation than that of control group.In conclusion, complex water soluble vitamins could increase the production performance and non-specific immune function, improve the oxidative resistance and relieved the heat stress of the dairy cows.
