种植饲料作物舍饲养牛经济效益的分析

在土质、光、热、水、肥和管理完全相同的情况下,每公顷种植青贮玉米的产量达63000kg,干物质产量21000kg、代谢能产量189000MJ、蛋白质产量1575kg,经济效益8340元。分别比种植玉米(收获粮食和秸秆)高出33.1%、17.98%、48.9%和66.8%;种植紫花苜蓿的干草产量达9300kg,其中干物质产量8091kg、代谢能产量75330MJ、蛋白质产量1581kg,经济效益5740元。比种植大豆高出199.7%、82.0%、35.2%和19.6%。可见种植优质饲料作物能够在同等面积的土地上生产出更多的营养物质,同时也能够获得较好的经济效益。种植饲料发展养牛,每公顷可产生经济效益10740元,比用来种植玉米(包括秸秆总计5000元)提高5740元,增效幅度高达114.8%。种植的首选饲料作物是青贮玉米和紫花苜蓿。

Analysis of the Economic Benefits of Planting Fodder Crops for Feeding Cattle

In the same conditions of soil, light, heat, water, fertilizer and management, 63 000 kg silage corn feed can be gained per hectare, output of dry biomass is 21 000 kg, output of metabolism energy is 189 000 Mj, protein production is 1 575 kg, and 8 340 yuan RMB can be obtained. It is 33.1%, 17.98%, 48.9% and 66.8% higher than planting maize (grain and straw), respectively. Hay production reached 9 300 kg, dry biomass production reached 8 091 kg, metabolism energy production reached 75 330 kg, protein production reached 1581 kg, and economic benefit was 5740 yuan RMB, if alfalfa was planted. It is 199.7%, 82.0%, 35.2% and 19.6% higher than growing soybean. From this we can see that more nutrients can be obtained from the same area of land if good fodder crops were planted, at same time more economic benefit can be obtained. In addition, using these fodder crops to develop cattle-feed production can attain economic benefits 10 740 yuan RMB per hectare,which is 5,740 yuan more than planting maize (total is 5 000 yuan including straw). The economic output increased as much as 114.8%.Silage corn and alfalfa is two feed crops to be grown.
