Synchronization of estrus in beef cattle
Theriogenology, 1978Abstract Five experiments were conducted with 647 virgin heifers and 821 lactating cows to determine the effectiveness of an estrous synchronization treatment involving an ear implant containing 6 mg of 17α-acetoxy-11β-methyl-19-nor-preg-4-ene-3,20-dione (norgestomet) and an injection of varying levels (5 to 7.5 mg) of estradiol valerate (EV) at the ...

Estrus synchronization in sheep with synthetic progestagens
Tropical Animal Health and Production, 2009Sixteen 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.

[Synchronization of estrus in heifers with BOVISYNCHRON].
Archiv fur experimentelle Veterinarmedizin, 1975Heifers 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

Estrus synchronization and follicular development patterns in jennies
Journal of Equine Veterinary ScienceSeasonal 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 ...
