« La synchronisation des chaleurs chez la brebis de Race "Rembi"»

Abstract

This work enabled us to evaluate the reproductive potentialities of one of our most important ovine breeds, in the event the Rembi breed. ► During the experimentation, on the level of our witness group (n =05 ewes), we have obtained with the treatment of estrous synchronisation by vaginal sponges impregnated with progestagens (30 mg of FGA), an interval between shrinking of sponges to appearance of heats, of about 53h 49 mn With the second treatment, vaginal sponges (30 mg of FGA) associated with 300 U.I of PMSG, the interval between shrinking of sponges to appearance of heats was of about 46h 11mn With the third treatment, vaginal sponges (30 mg of FGA) associated with 500 U.I of PMSG, the interval between shrinking of sponges to appearance of heats, was relatively shorter, of about 39h 29mn
