Abstract


Good results in the breeding sector are achieved at primiparous sows only by implementing the best farm management because primiparous have a lower prolificacy in the first two gestations and the season when sowing is made has negative effects on gestation losses. The lower prolificacy is achieved in gilts sown in July-November and the highest in the spring and winter season. The largest parturition losses is achieved in primiparous sown in October with 2,12 ± 1,03 piglets/sow born and 0,91 ± 0,32 piglets mummified/sows, and at the lowest ones, at primiparous sown in March 1.12 ± 0.22 dead piglets and 0.63 ± 0.11 mummified piglets.
