OVULATION SYNCHRONIZATION (OVSYNCH) IN LIMOUSIN COWS

, 2011
In 1995, a hormonal protocol was introduced that precisely synchronizes the timing of ovulation in lactating dairy cows (Hoard’s Dairyman, August 25, 1995). Because this protocol synchronizes ovulation rather than estrus, it was called Ovsynch, and it is

ANÁLISIS DE LA EFICIENCIA REPRODUCTIVA DE LOS PROTOCOLOS HORMONALES PRESYNCH Y OVSYNCH EN VACAS HOLSTEIN [PDF]

A eficiência reprodutiva depende da redução do intervalo entre partos através da inseminação artificial ou monta natural levando a uma maior taxa de concepção em um menor tempo. Os protocolos de inseminação Presynch e Ovsynch são os mais utilizados.

Estudo comparativo dos protocolos de sincronização Double-Ovsynch e Presynch- Ovsynch ao primeiro serviço pós-parto em bovinos de leite na região de Estarreja [PDF]

Neste estudo propomo-nos comparar a taxa de conceção ao primeiro serviço pós-parto (TCF) em vacas leiteiras, obtida com dois protocolos de pré-sincronização diferentes com inseminação artificial a tempo fixo: Double-Ovsynch (DO) e Presynch-Ovsynch (PO).
