Fixed-time Insemination in Pasture-based Medium-sized Dairy Operations of Northern Germany and an Attempt to Replace GnRH by hCG

, 2016
A field study was conducted aimed at (i) evaluating the practicability of a fixed-time insemination regime for medium-sized dairy operations of north-western Germany, representative for many regions of Central Europe and (ii) substituting hCG for GnRH as

Análise do impacto na fertilidade da utilização de diferentes protocolos hormonais no maneio reprodutivo em vacas leiteiras [PDF]

, 2017
Dissertação de Mestrado Integrado em Medicina VeterináriaNas últimas décadas tem-se assistido a um declínio das taxas de gestação em explorações de produção leiteira. Uma das causas para esta diminuição é a falha na deteção de cios. Por conseguinte foram

Ovarian function and endocrine phenotypes of lactating dairy cows during the estrous cycle are associated with genomic-enhanced predictions of fertility potential

Journal of Dairy Science
: The objectives of this prospective cohort study were to characterize associations among genomic merit for fertility with ovarian and endocrine function and the estrous behavior of dairy cows during an entire nonhormonally manipulated estrous cycle ...

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).

A new presynchronization system (Double-Ovsynch) increases fertility at first postpartum timed AI in lactating dairy cows

, 2008
This study evaluated a novel presynchronization method, using Ovsynch prior to the Ovsynch-timed AI protocol (Double-Ovsynch) compared to Presynch-Ovsynch.
