Abstract
Breed improvement of pigs is a major way to increase the economic efficiency of pig production in the near future. Different ways are now available to achieve this goal; among them, the valorisation of the exceptional reproductive abilities of some pig breeds is likely to provide the largest improvement in sow annual productivity. The fattening and carcass traits of two and three hybrids on the basis of VP as a paternal breed were studied. The characteristics of the following four groups were compared: BM Х VP; L Х VP; (BM Х L) Х VP; (L Х BM) Х VP. The data showed good genetic growing abilities of the pig hybrids studied. In this respect the BM Х VP combination exceeds the other showing best-feed conversion ratio. VP breed in the position of a paternal breed contributed to higher carcass trait values of studied hybrids.
