SYNCHRONIZATION OF ESTRUS WITH PGF ANALOGUE IN EWES AND GOATS DURING TWO SEASONS
The Iraqi Journal of Veterinary Medicine, 1989 Trials had been made for synchronization of estrus in both ewes and goats during Summer and Autumn seasons following double injection of PGF 2α . The results showed that the synchronization of estrus as well as the conception rates in ewes were lower ...

Inseminations at Estrus Induced by Presynchronization Before Application of Synchronized Estrus and Ovulation [PDF]
Journal of Dairy Science, 2005 A controlled field study examined conception rates after 2 timed artificial insemination (TAI) breeding protocols conducted on 2 commercial dairy farms. Estrous cycles in postpartum lactating cows were presynchronized with 2 injections of PGF(2alpha) given 14 d apart (Pre-synch) and then, after 12 d, the standard Ovsynch protocol (injection of GnRH 7 d
