人工草地肉牛系统优化生产模式的研究

Research on the Optimization of Beef Cattle System on Sown Pasture

通过对贵州省独山县三个农户肉牛生产系统监测资料的分析,指出了原系统在冢畜对策方面存在的一系列问题,并对LDR系统进行了优化设计。经过优化的LDR新系统与原系统相比,每公顷草地产出的畜产品单位,由130.9APU提高到894.6APU,提高了5.8倍。每公顷草地的销售毛利,由101.64元提高到1698.36元,提高了15.7倍。

Analyzing the monitor information for three beef cattle system(LDR, LSX, MSX farmers), a series of problems about the stock policy for the old systems were put forward. A new system (improved system) was designed for LDR system. Compared with the old system, the output of animal product units(APU) of the new system increased from 130. 9 APU/hm^2 to 894.6APU/hm^2 which was about 6.8 times that of the old system; The Gross Margin per hectare increased from 101.64 to 1698.36 Yuan/hm^2 which was 16.7 times that of the old system.
