Veterinarski Glasnik 40(2-3): 183-190
In the report different possibilities are described for synchronizing fertile oestrus in ewes in the anoestrous season, as well as in the mating season when oestrus occurs spontaneously. A high percentage of synchronized fertile oestrus is achieved in ewes by using different combinations of hormone preparations (progesterone, gonadotropins, PMSG, prostaglandins and others).
