This study investigated the interactive effects of weather conditions, transportation time and loading density on carcass damages and meat quality traits of pigs. Pigs exposed to short transportation at low space allocation during hot weather conditions produced the lowest pork quality. Pigs exposed to short transportation at high loading density during cold weather conditions produced the highest pork quality. Hence, weather and transport conditions are of great importance for the pork quality.

Here, we investigated the effect of sire line on growth performance and carcass traits of crossbred offspring under standardized environmental conditions. Pigs sired by a synthetic line showed benefits in fattening performance and Piétrain crossbreeds were characterized by a better carcass value. The synthetic line is preferable in terms of the number of fatting pigs per fattening place and year, while the Piétrain line provides increased leanness and carcass cuts.

In recent years, there has been a current trend in the pork market to create products based on traditional specialities, where technology such as drying, smoking and fermentation of products is used. For this reason the aim of study was to compare the genotypes from Slovakia and Poland. Genotypes from Poland are more suitable than those from Slovakia for the breeding and production of special meat products due to acceptable fattening and carcass parameters as well as the meat quality.
