Abstract:

本试验旨在研究补饲硒和维生素E对泌乳水牛隐性乳房炎发病率的影响。将70头泌乳水牛按胎次、泌乳阶段、产奶量、体重相似的原则随机分成2组,均饲喂基础饲粮(2.0mg/d硒和120IU/d维生素E),试验组补饲1.6mg/d硒和200IU/d维生素E,每组各35头。试验期107d,前7天为预试期。检测隐性乳房炎发病率、血浆硒、维生素E含量以及谷胱甘肽过氧化物酶活性的变化。结果表明:与对照组相比,试验组隐性乳房炎乳区发病率60d时下降了34.06%,90d时下降了43.11%,2组间个体发病率和乳区发病率差异均不显著(P>0.05);正试期内试验组血浆硒和维生素E含量均显著或极显著高于对照组(P<0.05或P<0.01),60d时,试验组血浆谷胱甘肽过氧化物酶活性显著高于对照组(P<0.05)。结果提示,与饲喂2.0mg/d硒和120IU/d维生素E相比,泌乳水牛补饲1.6mg/d硒和200IU/d维生素E显著提高了血浆中硒、维生素E含量及谷胱甘肽过氧化物酶活性,并有降低隐性乳房炎发病率的趋势。
