Economic success, i.e. obtaining profit on swine farms is influenced by managerial factors that ensure performing standards of reproduction parameters in swine by diminishing service period and by achieving a calving interval between 152-154 days. Obtaining from each sow 2.37-2.40 calvings per year over a longer period of exploitation (6-7 calvings) contributes to the recovery of occasional expenses with the raising of breeding stock until the optimal age for reproduction.
