【摘要】 本试验目的在于评价红豆草和苜蓿的生产能力及营养价值。第二年盛花期红豆草的干草产量比苜蓿高30%,蛋白质高13%,14种氨基酸的含量也高于苜蓿。红豆草花期的落叶量少,茎较柔软,含有2～3%的丹宁,不会引起鼓胀病,但适口性较苜蓿差.鲜草饲喂生长肉兔的效果不如苜蓿,草粉配合料饲喂肥育兔的效果相近;压缩颗粒料饲喂生长肉兔的效果差异不显著.在绵羊试验中,结实期红豆草粉配合料的采食量比苜蓿的高14%,日增重高17%;盛花期分别高10%和27%.两种牧草对兔和绵羊的消化能差异无几.更多还原

【Abstract】 Lucerne and sainfoin are important ruminant and non-ruminant forages in east Gansu Province in central nothern China.this study was undertaken to determine whetherthese reported differences were important and increase the knowledge of theseforages in this region.The biomass production of sainfoin and lucerne were measured at budding,flowering and maturing stages from 1984 to 1987.Sainfoin produced more biomass than lucerne in the first three years after whic lucerneat flowering was used more efficiently than sainfoin by growing For forages cut at flowering stages,the DM intake and weight gain of the sheep that were feed sainfoin were greater.These findimgs suggent that tannins which occur in sainfoin may have haa role in increasing the efficiency of protein use by the sheep.更多还原
