Induction and Synchronization of Estrus
, 2021 Estrus cycle is a rhythmic change that occur in the reproductive system of females starting from one estrus phase to another. The normal duration of estrus cycle is 21 days in cow, sow, and mare, 17 days in ewe, and 20 days in doe. The species which exhibit a single estrus cycle are known as monstrous and species which come into estrus twice or more ...

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

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 ...

Advanced Science, EarlyView.A dual‐color pseudo‐menstrual mouse model enables real‐time tracing of circulating endometrial cells (CECs) from uterine and ectopic sources. The study reveals menstrual‐phase‐dependent, burst‐like CEC release, distinct postoperative behaviors of different CEC origins, and a potential association with prolactin fluctuations, providing an in vivo ...
