摘　　要：以年产奶6100kg奶牛的饲养标准为依据,以高丹草健宝、紫花苜蓿、青贮玉米等为青粗饲料,根据饲草料的营养物质含量和奶牛的采食要求,分阶段进行奶牛的日粮配方,再以奶牛的日粮配方和西辽河平原灌溉条件下牧草、饲料作物的平均产量为依据,确定与奶牛饲养相适应的饲草料种植模式.按该种养结合模式饲养1头高产奶牛,需种植牧草、饲料作物0.346 hm2,年效益为5998.78元,较传统方式饲养奶牛效益增加1.39倍,较单纯种植玉米每hm2土地的经济效益增加1.89倍.According to feeding standards of cow of 6 100 kg output of milk per year, nutritive value of S. bicolor ×S. sudanense cv. Jumbo, Medicago Sativa L. and Zea mays L. etc. , the feed formulas of cow in different stages were drawn up. Then the cropping patterns of forage crops for raising cow were laid down by the feed formulas and average yields of forage crops under irrigation in Xiliaohe Plain. The cropping pattern of forage crops for raising a high production cow need 0. 346hm^2 cultivated area. The annual benefit of a cow is 5998.78 ￥, 2.39 times of benefit of a cow in condition of traditional husbandry model, and 2.89 times benefit of corn planting in one hectare.
