试验旨在明确饲料中不同添加量的海甘蓝(CM)替代大豆对羔羊采食量、生长性能、血液参数、胴体品质和肉品质的影响。选取特塞尔羔羊80头,包括40头公羊(23.3±0.98 kg)和40头母羊(22.1±0.95 kg),随机分成4组,饲料分别添加CM 0、64、128、192 g·kg^(-1)。结果表明,干物质采食量与CM添加量成线性增加关系,但添加CM对消化率和体增重无显著影响。随着饲料中CM含量的增加,料重比降低。各组间胴体重量和商用肉含量无显著差异。饲料中添加较高含量CM使羔羊肌肉比例和肉骨率降低。随着CM添加量的增加,公羊皮下脂肪含量显著低于母羊,公羊和母羊间除皮下脂肪含量不同,其他各组数据相近。各组间的背最长肌的化学组成和肉品质均相似。试验结果表明,当CM在生长期羔羊饲料中添加量达到192 g·kg^(-1),日粮精粗比为350~650时,CM对羔羊胴体品质和生产性能无不良影响。
