This thesis is dealing with issues of reproductive markers in breeding of pigs at family farm. In literary part of thesis is described development in pigs stud all around the world, development in numerical quantity of pigs, reproduction in pigs stud, natural breeding and insemination, period of preparation for own delivery. As further also loss of piglets up to and after wean. Biological basis for growth intensity of pigs, evaluation of growth of pigs meant for slaughter. Diseases of pigs. Technological housing of pigs. In research part of thesis, we watched reproductive markers of sows as length of gravidity, number of born piglets, weight of piglets at the wean, mortality of piglets, average daily increase of piglets from birth till wean, total increase of piglets, milk production of sow, length of breast-feeding, period from wean to after service and length of service period. On basis of these data we found average number of born piglets, length of gravidity, average daily increases, influence of sow´s breeding, mortality of piglets according pig´s breed, watched influence of reproduction in chosen breed of sown, as further also influence of sow´s breed on growth intensity of piglets, influence of boar on number of born piglets and their growth, number of serviced sows, and if it´s influencing birth weight of piglets. We used statistical program STATISTICA 10.0 for evaluation of data in which we used data variation analysis to evaluate influence of monitored factors. HSD test was used for determination of provability amongst groups.
