MICHALSKA, G., J. NOWACHOWICZ, T. BUCEK, P. D. WASILEWSKI and M. KMIECIK, 2014. Performance test of young crossbred boars from the Bydgoszcz breeding region in Poland. Bulg. J. Agric. Sci., 20: 1255-1260


The aim of presented research was performance test analysis of young crossbred boars came from 6 crossing variants conducted in years 2009 and 2010 in Poland, in The Bydgoszcz Breeding Region. The research covered the performance test results of 1911 young crossbred boars conducted with accordance to obligatory modified methodology. The animals came from the following crossing variants (sows breed given in the first position): Hampshire x Duroc (H x D), Hampshire x Pietrain (H x P), Duroc x Hampshire (D x H), Duroc x Pietrain (D x P), Pietrain x Hampshire (P x H) and Pietrain x Duroc (P x D). Duroc x Hampshire young crossbred boars had the highest growth rate, the thinnest backfat, the highest height of loin eye and the highest selection index value. The highest meat content in 2009 had animals of Pietrain x Duroc and Hampshire x Pietrain, and in 2010 Duroc x Hampshire pigs. Analysing the results from years 2009 and 2010 it was obsered that the increase of performance test selection index value occurred in crossbreds of Hampshire x Duroc, Hampshire x Pietrain and Pietrain x Duroc (by 4, 4 and 2 points, respectively). In case of the remaining groups of pigs deterioration (by 1-2 points) of performance test selection index has been observed or there was no change.
