本试验旨在研究青贮桑叶替代青贮玉米对奶山羊生产性能、乳品质、养分表观消化率、瘤胃发酵参数和血清生化指标的影响。试验选择30头胎次、产羔日期、产奶量、体重相近的西农萨能奶山羊,随机分成2组,每组15头。玉米组饲喂青贮玉米全混合日粮,其酸性洗涤纤维、中性洗涤纤维、粗蛋白质含量和消化能分别为26.97%、47.05%、17.54%和5.56 MJ / kg;桑叶组饲喂青贮桑叶全混合日粮,其酸性洗涤纤维、中性洗涤纤维、粗蛋白质含量和消化能分别为25.62%、46.85%、17.88%和5.67 MJ / kg。预试期10 d,正试期42 d。结果表明:1)桑叶组的干物质采食量极显著高于玉米组(P

The purpose of this experiment was to study the effects of silage mulberry leaves instead of silage corn on performance, milk quality, nutrient apparent digestibilities, rumen fermentation parameters and serum biochemical indexes of dairy goats. Thirty Xinong Saanen dairy goats with similar parity, lambing date, milk yield and body weight were randomly divided into 2 groups with 15 goats per group. Goats in the corn group were fed a silage corn total mixed ration, in which the contents of acid detergent fiber, neutral detergent fiber, crude protein and digestible energy were 26.97%, 47.05%, 17...
