世行项目户不同投资模型下的收益状况分析

Income Analysis of Different Investment Models of the World Bank Project Households

通过对36户不同规模的世行项目户2008年种植业、养殖业经营状况、家庭收入、肉牛育肥情况的调查分析，3～19头小型育肥户主要以饲养繁殖母牛和育肥犊牛为主，饲养管理相对粗放，生产周期较长，虽然效益不高，但抵御市场风险的能力较强，20-49头中型和50～150头大型户主要靠外购架子牛育肥，投入大，饲养管理规范，育肥期短，周转快，效益相对高，但容易受市场波动的影响。在目前农户耕地和种植结构不变的情况下，依靠饲养母牛自繁自育，较为适宜的饲养规模应在10头左右。

By investigating and analyzing the management state of planting, feeding, family income and beef cattle fattening situation of different scale＇s cattle fattening households summing to 36, which was supported by World Bank project in 2008, it was found that the small scale cattle fattening households breeding 3 to 19 cattle mainly raised reproduction cows and fattening calves, the pattern had the characteristics of the relatively extensive breeding management, the longer production period, the lower benefit and the stronger capacity of resisting market risk. In addition, the medium and large scale beef cattle fattening households breeding 20 to 49 and 50 to 150, respectively, mainly purchased store cattle to fatten. The pattern had the characteristics of heavy investment, standard feeding management, fast turnover, the higher benefit and being easily affected by the market fluctuation. At present, if the structure of farmland and planting kept invariable, the optimum scale depending on self-reproduction was around 10 cattle.
