Estrus synchronization in sheep with synthetic progestagens

Tropical Animal Health and Production, 2009
Sixteen female sheep of Degua breed were assigned to receive either the full dose of norgestomet ear implant and injectable solution containing norgestomet and estradiol valerate (n = 8) or half the dose (n = 8). The ear implants were removed in both groups on day 12.

Estrus induction and synchronization in canids and felids

Theriogenology, 2007
Indications for estrus induction in the dog and cat include potential missed breeding opportunities or conception failure, the treatment of primary or secondary anestrus, out-of-season breeding (feline) and synchronization of ovulation for embryo transfer programs. Reported methods for estrus induction in bitches and queens include the use of synthetic

Continuous presence of male on estrus onset, estrus duration, and ovulation in estrus-synchronized Boer goats

Theriogenology, 2016
The objectives of the present study were to assess the effect of permanent contact of teasers without copulation on the interval from controlled internal drug release (CIDR) removal to estrus onset, estrus duration, ovulation time, number of ovulations, and interval from CIDR removal to ovulation time on estrus-synchronized Boer goats.

Estrus synchronization and follicular development patterns in jennies

Journal of Equine Veterinary Science
Seasonal variations and breed differences significantly influence reproductive efficiency in jennies, yet optimized, evidence-based estrus synchronization protocols for key Chinese breeds are lacking.This study aimed to compare the efficacy of three hormonal protocols on estrus synchronization, and to characterize follicular development patterns in ...

[Synchronization of estrus in heifers with BOVISYNCHRON].

Archiv fur experimentelle Veterinarmedizin, 1975
Heifers were each given 2ml of 1% solution of chlormadinone (CAP, Bovisynchron) for 15 days. Those in group I received one daily dose, while group II received half the dose twice a day. Oestrus was synchronized in all but two heifers. In group II there was a concentrated occurrence of oestrus, so that all heifers could be inseminated on the 5th and 6th

Hormonal Induction and Synchronization of Estrus in Mice

The present study was carried out to evaluate different estrus synchronization protocols in mice and follow up the proportion of delivery and gender of litters. Five protocols were tested with total number of 48 adult females that divided equally into six groups including control.
