Abstract
In rearing pigs for fattening in addition to those environmental significant impact on the size characteristics of vital economic is the genetic value their parents. In order to convince the experiment has been carried out on two genotypes pigs for fattening, on the holding of average and similar conditions of rearing in the Lower Silesia. Assessing the value of fattening, slaughter and meat were 242 pigs for fattening crossbreeds [Polish Large White x Polish Landrace x P-76] and 195 crossbreeds [Naima x P-76]. In both cases the father of the fatteners was a boar P-76. In turn, the maternal material differed in place of origin. The sows [Polish Large White x Polish Landrace] ware from Poland whereas Naima was from France. The study shows that under the influence of slaughter and the meat content of carcass were better after the Polish saws compared with the French. The fatteners [Polish Large White x Polish Landrace x P-76] characterized by major hot carcass weight and hot dressing percentage compared with the fatteners [Naima x P-76]. The differences between the average values of these characteristics were statistically confirmed (P≤0.05).
