| 摘 要： | 设4种不同梯度多花黑麦草Lolium multiflorum和配合饲料的日粮组成对24头黑白花奶牛进行饲喂试验,以期探讨最佳经济效益的日粮组成,为推广饲用玉米Zea mays-多花黑麦草种植系统提供理论依据.结果表明,随配合饲料饲喂量的减少,多花黑麦草采食量增加,青贮玉米的采食量不断减少.以每头饲喂6 kg配合饲料 30 kg多花黑麦草 自由采食青贮玉米试验组(2组)奶牛每天平均产奶量最高,达到11.59kg/头.以每头饲喂5 kg配合饲料 40 kg多花黑麦草 自由采食青贮玉米试验组(3组)奶品质最好,经济效益最高.

| Abstract: | 24 black and white dairy cows were fed with 4 kinds rations made of Italian ryegrass and concentrates to find the most economic ration compositions and provide theoretical basis for silage corn-Italian ryegrass growing system.The result showed that with the decrease of concentrate,the intake of Italian ryegrass increased,meanwhile,the intake of silage corn reduced gradually.The group two fed with 6 kg concentrate 30 kg Italian ryegrass free intake of silage corn had the highest milk yield,11.59 kg/head.The group three fed with 5 kg concentrate 40 kg Italian ryegrass free intake of silage corn gave the highest milk quality and profit. |
