摘　　要：从高油玉米种养结合出发,以高油115为例,研究高油玉米鲜秸秆、青贮秸秆、整株鲜秸秆、整株青贮对肉牛、奶牛生长的影响,结果表明:(1)饲喂高油玉米青贮秸秆后,肉牛采食速度加快,外观体况优于普通玉米．日增重比普通玉米增加0．15～0．30kg,增加率15％～30％。(2)饲喂高油玉米秸秆对奶牛产奶量影响显著,每头奶牛日产奶量比普通玉米提高1．8kg,提高率8%左右。同类牛群在饲喂高油玉米秸秆后,产奶量直线上升,同时,在后一阶段饲喂普通玉米秸秆始期,仍保持较高的产量水平。(3)高油玉米秸秆对改善牛奶品质效果明显,乳糖、乳脂率、乳蛋白含量等比普通玉米提高5%左右,提高1个等级。The article concatenates high oil maize growth with livestock breeding.The effect on growth of cattle and cows which were fed on fresh straw,silage straw,integrated fresh straw and integrated silage straw respectively is studied,and all the straw is the straw of Highoil No.115.Results as follows:(1)All the cattle fed on high oil silage maize straw exhibit that the their speed of taking food is higher,body appearance is better compared with those fed on common maize straw, and weight enhances 0.15～0.30 kg per day,and enhances 15%～30% than those fed on common maize straw.(2)It has signalized influence when the milk cows were feed on high oil maize straw,daily milk yield enhanees 1.8 kg every cow,and enhances around 8%.The milkability increases sharp when the congener cattle were fed on high oil maize straw,and their milkability still keeps leading when the high oil maize straw is substituted by common maize straw at the back stage.(3)It signalizes that quality of milk is improved when the milk cows were fed on high oil maize straw.The lactose,butterfat rate,lactoproteid content in milk produced by the crows fed on high oil maize straw increase around 5%,and the milk quality improves a grade than those fed on common maize straw.
