Effects on synchronization and reproductive efficiency of delaying the removal of the intravaginal progesterone device by 24 h in the 5d co-synch protocol in heifers
(2021)
In beef herds, increasing animal welfare, improving reproductive performance and easing
animal management are key goals in farm economics. We explored whether delaying the removal
of the intravaginal progesterone device ...
Timed artificial insemination programs during the summer in lactating dairy cows: Comparison of the 5-d Cosynch protocol with an estrogen/progesterone-based protocol
(2013-09-19)
The objective of this study was to compare a GnRH-based to an estrogen/progesterone (E2/P4)-based protocol for estrous cycle synchronization and fixed timed artificial insemination (TAI), both designed for synchronization ...

Strategies to improve fertility in postpartum multiparous Bos indicus cows submitted to a fixed-time insemination protocol with gonadotropin-releasing hormone and prostaglandin F-2 alpha
(Amer Soc Animal Science, 2009-09-01)
In Exp. 1, we evaluated the effects of 2 lengths of progesterone exposure [CIDR (controlled intravaginal drug release); 7 vs. 14 d] before a modified CO-Synch protocol [50.0-mu g injection of GnRH 6.5 d before a 25.0-mg ...
