Abstract

The purpose of this paper was to improve the reproductive performances of sows after weaning in a private swine farm. The main objective was to implement modern reproductive biotechnologies (estrus synchronization, artificial insemination and early pregnancy diagnosis) in order to increase the economic efficiency of the reproductive sector of this farm. The biologic material used for the research was represented by 300 sows whose estrus was synchronized using three hormonal procedures (Regu-Mate administered collectively, Regu-Mate administered individually and PG600) as well as naturally, using stimulating boars. The results showed that the best methods of estrus induction and synchronization in sows use either Regu-Mate administered individually in fodder or PG600.
