| This paper comparatively analyzes the breeding costs and culture benefits of live pig indifferent farms in Shaanxi province and discusses the live pig breeding scale that suitable forShaanxi.The live pig breeding scale is divided into small (50to499heads), medium (500to2999heads) or large (above3000heads) according to the Pigs Slaughter quantity of year. We figureout the sales and the costs of every100kg pig by collecting and analyzing monthlyproduction data of545live pig scaled-breeding farms from January to December during2013.From the surveys that we released to100live pig scaled-breeding farms, we work outthe depreciation of fixed assets and operation costs of slaughtering100kg pig to differentscaled farms. We establish the selected model in Shaanxi live pig scaled-breeding based ongrey situation decision method,comprehensively analyze and evaluate the advantages anddisadvantages of breeding costs and culture benefits in different scaled-breeding farms. Theresults are as follows:1ã€Small scaled-breeding costs are relatively low and economic benefit is supreme. Thecomprehensive effect measure of0.938.2ã€Medium scaled-breeding costs are very close to small scaled-breeding expensesoperation costs and the breeding economic benefits are also in the middle. The comprehensiveeffect measure of0.896.The management level and technical level of medium scaled-breedingare all higher than small scaled-breeding and it is the developing direction for Shaanxi scalepig breeding.3〠Large scaled-breeding costs are higher， economic benefit is lowest. Thecomprehensive effect measure of0.894.Therefore, at present and the future Shaanxi Province shall focus on the development ofsmall scaled-breeding and medium scaled-breeding. |
