P. C.  aSynchronization of oestrus in sheep of low-normal mass under range conditionsbthe use of different progestagens and PMSG.h[electronic resource]  c1988  aA major objective of this investigation was to verify that FGA (fluorogestone acetate) intravaginal sponges exhibit a more compact oestrus responses and a greater conception rate following sponge withdrawal, than do MAP intravaginal sponges, in sheep outside the normal breeding season. More specifically, the effect of different doses of PMSG on synchronzation efficiency, the implementation of two vs one insemination at a fixed time following synchronization, as well as the effect of ram breed on fertility were investigate.  aEstrous cycle  aEstrus synchronization  aEwes  aReproduction  aSheep  aCiclo Estral  aMerino  aOvino  aReprodução  aEstro  aIntravaginal progestagen  aNumber of inseminations  aPMSG  aSincronizacao1 aGREEFF, J.
