Abstract. Experimental material comprised 47 Złotnicka Spotted sows, coming from 2 piggeries keeping Złotnicka pigs within conservative breeding. Slaughter performance was evaluated on carcasses coming from their offspring (112 carcasses – Złotnicka Spotted x Duroc) and 16 carcasses coming from purebred animals. The following reproduction performance traits of sows were investigated: the number of piglets born in the litter and the number of piglets reared 21st day, and the following slaughter performance traits of their offspring were analyzed: weight of caracass (kg), mean backfat thickness (mm), height of loin eye of the longissimus dorsi muscle (mm) and meat percentage in the carcass (%). The most numerous litters, both at day 1 (10.16 head) and on 21st day of life (9.99 head), were those sired by Duroc boars. Recorded differences turned out to be statistically high significant. The breed of the sire also had a significantly high effect on meatiness of fatteners.
