ANALYSIS OF CHANGES IN LEAN MEAT CONTENT OF FATTENING PIGS ON SELECTED FARMS IN THE LUBLIN VOIVODESHIP IN 2012-2014
P. Witkowski, A. Apostolov, B. Szostak
Abstract: The material for analysis consisted of pig carcasses weighing 80–90 kg from three farms located in the south-eastern part of the Lublin Voivodeship (from the villages of Lipowiec, Dęby and Gorajec). Commercial crossbreeding of pigs on these farms is based on the use of Polish Large White x Polish Landrace sows and Duroc x Piétrain boars. The analysis covered the years 2012–2014. The lean meat content of the carcasses obtained from each of the producers was characterized on the basis of on arithmetic mean (x) for each farm and year of production. The percentage distribution of the carcasses in each of the classes S, E, U, R, O, and P was analysed as well. The lean mean content of the carcasses evaluated can be considered good. On each of the farms analysed carcasses in classes E and S were predominant. However, the decline in average meatiness on the farms in Lipowiec and Gorajec in the last year of the analysis (2014) with respect to the previous years is worrisome. A thorough analysis should be conducted on these farms to determine the cause of the reduction in meat content. The differences in the meat content of the carcasses from the farms analysed are the result of different environmental factors on these farms, mainly diet and housing conditions.
