生产牛奶，固体非脂肪，脂肪校正牛奶，牛奶脂肪和牛奶蛋白质的奶牛红豆草比那些喂苜蓿干草在2个回转试验。干草和谷物的消费量没有不同的奶牛接受不同的干草。在一项适口性研究中，6个月。老母牛更喜欢红豆草而不是苜蓿草。成熟公羊的代谢研究得出红豆草干草的干物质、蛋白质、乙醚提取物、粗纤维和无氮提取物部分的消化系数分别为65%、63.3%、59.2%、31.6%和85.5%。肉牛的消化率分别为59.6、44.9、67.4、35.1和72.9%。平均日增重和饲料消耗量没有不同的319公斤小母牛充分喂养红豆草或苜蓿干草60天。
Production of milk, solids-not-fat, fat-corrected milk, milk fat and milk protein were lower for cows on sainfoin hay than for those fed alfalfa hay in 2 switch-back trails. Hay and grain consumption did not differ for cows receiving the different hays. In a palatability study, 6 mo. old heifers preferred sainfoin hay to alfalfa hay. Metabolism studies with mature rams gave digestible coefficients of 65, 63.3, 59.2, 31.6 and 85.5% for dry matter, protein, ether extract, crude fiber and N free extract portions of sainfoin hay. Digestibilities with steers were 59.6, 44.9, 67.4, 35.1 and 72.9%. Average daily gain and feed consumption did not differ for 319 kg heifers full-fed either sainfoin or alfalfa hay for 60 days.
