The aim of thestudy was to comparethe profitability ofpig productionof twobreeds:the Polish Landrace (PWL)andthe Pulawska kept at a family farm. The analysis includedindicators of reproductive performanceof sowsand the parameters of attening and slaughter value.The data included the production offattening pigsat the farm in the years 2010–2012. The analysis performedndicate thatprofitability offatteningpigs of the Polish Landracebreed compared to the Pulawska breed was variable. It has been shownthat regardless of theperiod of the production ofporkers a lower profitwas obtained from the sows of the Pulawska breedas compared to the Polish Landrace.This result was influenced by lower ratios of reproduction sowsof the Pulawskabreed,and higher feed consumption, lower weight gainsand lower meat content in the carcass of porkers raised from them.
