PRELIMINARY TESTS ON THE INDUCTION OF ESTRUS DURING THE NON-BREEDING PERIOD IN TURCANA SHEEP
Abstract - Reproduction in sheep is a topic of interest, finding an efficient method depending on the breed of sheep, the livestock of the farm and the geographical region is a permanent challenge in zootechnical farms. Inducing and synchronizing oestrus during non-breeding season is an essential technological method of assisted reproduction for sheep. The study proposes a method of inducing and synchronizing estrus during non-breeding season based on vaginal sponges with FGA, the administration of PGF2α and GnRH in sheep of the Turcana breed. Several parameters were analyzed: sponge loss rate, vaginitis onset rate, total percentage of ewes in estrus and gestation rate. Based on the values of the induction rate and the synchronization of estrus during non- the reproductive period in sheep from the Turcana breed of 86.66%, respectively a gestation rate of 88.46% we can conclude that the method used was the efficiency.
