Estrous synchronisation and artificial insemination in out of breeding season at lacaune sheep

Abstract

The aim of this study was to increase fertility in sheep by applying modern biotechnology: induction and synchronization of estrous in out of breeding season. The study was conducted during May 2019- July 2019 on 132 ewes, aged between 1 and 6 years, in Covasna county, Romania. The ewes were syncronisated with Medroxyprogesterone (Ovigest, Hypra), Cloprostenol (PGF Veyx Forte, Esteve) and GnRH (Ovarelin, Ceva). After the synchronization, the artificial insemination was performed at 126 ewes by intracervical method. At 29 days after the artificial insemination was performed the diagnosis of gestation using an ultrasound. From 126 animals artificial inseminated, in 121 (91.67%) cases the diagnosis of gestation confirmed the gestation and in 22 cases was confirmed a twin gestation.
