Live testing results of Z?otnicka Spotted (ZS), ZS ? Polish Large White, and ZS ? Hampshire fatteners

摘要

Investigated was the fattening potential of purebred Z?otnicka Spotted (ZS, n = 423), ZS × Polish Large White (ZSPLW, n=36) and ZS × Hampshire (ZSH, n=31) pigs using the PIGLOG 105 apparatus. The best results were shown in ZSPLW crossbreds (from ZS sows by PLW boars) characterized by higher meat content of carcass, better live weight gain and thinner backfat than in the other two groups. The results suggest the use the ZS breed for production of crossbred fatteners on a wider scale.
