摘要: [目的] 分析四川省3种养猪生产系统,DLY、PIC和土二杂的经济效益。[方法] 通过建立利润方程计算和比较各生产系统的经济效益,同时对影响各生产系统的因素用差额法进行灵敏性分析。[结果] 得出PIC系统的单位产品经济效益为375.72元,高于DLY系统的336.81元和土二杂系统的273.31元:得出影响系统的重要因素为,商品猪育肥期,育成期和保育期的饲料价格和饲料转化率,商品猪哺乳期成活率、父母代母猪妊娠期饲料价格、父母代母猪年产胎次、父母代母猪单胎产活仔数和商品肥猪价格。[结论] PIC系统获得的经济效益更高,本研究既分析了影响养猪经济效益系统的自身因素,又分析了市场行情对经济效益的影响,可为四川养猪生产提供一定的参考。

Abstract: [Objective] This paper aims to analyze three kinds of pig production system of Sichuan province,regarding to DLY,PIC and Local hybrid economic benefit.[Method] Profit equation is established to compute and compare the economic benefits of each production system,in the meantime to analyze the sensitivity of factors that influence each system by using the difference method.[Results] Results suggest that economic benefit of the three systems are PIC 375.72 yuan,which is higer than those of DLY 336.81 yuan,and local hybrid 273.31 yuan respectively.Besides,they indicate that the important factors affecting system are feed prices and feed conversion rate ofcommercial fattening period,incubation period as well as the conservation period;feed prices and feed conversion rate;commercial survival rate of breastfeeding;parents generation sow gestation feed prices;parents generation sow produces tire,parents generation sow singletons number born alive as well as hog prices.[Conclusion] The PIC system obtains the highest economic benefits,this study analyzes not only the factors those influencing pig economic benefit system itself,but also the influence of market on economic benefits,which can provide certain reference for the Sichuan pig production.

Key words: economic benefit, production system, sensitivity analysis, difference estimation
