The influence of factors (breed, year and season of farrowing, herd, parity order, sire of litter, total number of born piglets – TNB, number of piglets born alive – NBA, number of weaned piglets – NW, and linear and quadratic regression) on the number of teats, found for all piglets in the litter till ten days after born, expressed as arithmetic mean for each litter as sum of all teats number of each piglet in appropriate litter divided by number of piglets in this litter at first litter (ANT1) and second and subsequent litters (ANT2+) were analysed. The coefficient of determination was 0.46 and 0.33 for ANT1 and ANT2+, respectively. The statistically high influence (P
