本试验旨在研究饲粮中添加迷迭香提取物对奶山羊生产性能、抗氧化能力及免疫功能的影响。选取24头胎次相近、泌乳日龄和日均产奶量相近的西农萨能奶山羊,随机分成2组,每组12头。对照组饲喂基础饲粮,迷迭香提取物组在基础饲粮中添加2.14 g / kg(在饲粮中的占比为0.213%)的迷迭香提取物。预试期10 d,正试期42 d。结果显示:1)饲粮中添加迷迭香提取物对奶山羊的干物质采食量、产奶量、奶料比没有显著影响(P>0.05),对奶山羊的干物质、粗蛋白质、粗脂肪、中性洗涤纤维、酸性洗涤纤维摄入量和表观消化率亦没有显著影响(P>0.05) 。 2)第21天和第42天,迷迭香提取物组的血清谷胱甘肽过氧化物酶(GSH-Px)活性...

This experiment was conducted to study the effects of dietary rosemary extract on performance, antioxidant capacity and immune function of dairy goats. Twenty-four Xinongsaneng dairy goats with similar parity, lactation age and average daily milk yield were selected. They were randomly divided into 2 groups with 12 goats in each group. The goats in control group were fed a basal diet, and those in rosemary extract groups were fed the basal diet supplemented with 2.14 g / kg(the proportion in the diet was 0.213%) rosemary extract for 10 d pre-feeding period and 42 d formal feeding period. The r...
