dc.description.abstractThe aim of the experiment was to analyze selected reproductive characteristics in sows and losses of piglets according to their age and to evaluate the effect of sex on survivability of piglets before weaning. The experimental observation involved 80 sows with their second litters (40 sows of genotye I and 40 sows of genotype II). The sows were mated with a boar of Danish Duroc. No significant difference was found between the evaluated genotypes of sows in numbers of live-born piglets and reared piglets, however it is evident that better results were reached by the sows of the genotype II. Also the losses of piglets per litter were lower, by 0.65 piece (P <- 0.05). In sows of the genotype I a high correlation (P <- 0.01) was confirmed between the number of live-born piglets and the number of reared piglets per litter (r = 0.750). Another correlation was found between the number of live-born piglets and their losses before weaning (r = 0.716). Similar trend was observed in the genotype II, however without significant correlation between the number of live-born piglets and the losses of piglets before weaning. The results also revealed that the piglets died mostly before the 14th day of age, while the losses of male piglets were more frequent than of female piglets. Losses of female piglets of the genotype I before the 14th day of age were 6.82 %, in the genotype II they were 3.01 %. In this period, the losses of male piglets reached 9.56 % in the genotype I and 4.49 % in the genotype II. From the 14th day to weaning the losses of female piglets counted 2.39 % vs. 0.75 %, the losses of male piglets 1.37 % vs. 2.88 %. The total losses from birth to weaning were 9.22 % vs. 3.76 % in female piglets and 10.92 % vs. 7.37 % in male piglets.en
