Durante más de medio siglo, se ha adoctrinado a los productores de leche en el uso de la regla A. M. / P. M. para la inseminación artificial (IA) del ganado lechero. En esencia, la regla A. M. / P. M. dicta que una vaca debe ser inseminada artificialmente 12 horas después de haber sido observada en estro (celo). Si una vaca se ve en celo en la mañana, debe ser inseminada artificialmente en la tarde y, a la inversa: las vacas en estro en la tarde deben ser inseminadas artificialmente a la mañana siguiente.
Estrategias para mejorar el desempeño y manejo reproductivo Presentador Resumen Presentador Dr. Julio Giordano Profesor del departamento de Ciencias animales Universidad de Cornell Resumen La reproducción es un pilar fundamental en la producción lechera. Un buen manejo reproductivo se traduce en un mayor número de partos, un intervalo calórico más corto y, en última instancia, […]

Today, we can form our own pyramid of characteristics for high performing dairy herd reproductive management. During a recap of the 2024 Reproduction Roadshow, Dr. Paul Fricke, Dairy Cattle Reproduction Specialist for UW-Madison and Division of Extension, introduced his building blocks for top reproductive performance and how achieving each step opens more opportunities to use additional reproductive technologies.
Proper semen handling requires being comfortable with a liquid nitrogen tank so you can work quickly and effectively to avoid damaging frozen semen.
Why do cows that face a common challenge (Stress) respond differently to it (Strain), and how do managers capitalize on this?
Advances in activity monitoring technology have taken electronic estrus (heat) detection from concept to reality on more dairy farms today. This is of significance because estrus detection has historically been a challenging task.
Kent Weigel, Professor and Chair of the Department of Animal and Dairy Sciences at the University of Wisconsin – Madison Division of Extension, presents on current research on the day-to-day consistency of dry matter intake, milk yield, and the genetics behind it.
Advances in dairy genetic research have created an ever-increasing amount of information for dairy farmers to take into consideration for sire selection. Dairy sire proofs contain a mix of numbers, acronyms, and other terminology. This reference guide covers common sire proof information and what it means.
The Council for Dairy Cattle Breeding releases updated dairy sire summaries in April, August, and December. The science of sire summaries has changed in recent years. More traits, especially for health, longevity, and efficiency can now be evaluated and included for selection.
Synchronization protocols evolve rapidly as newer procedures are tested and improvements are made. To help veterinarians and industry professionals deal with rapid change and make informed decisions related to synchronization protocols, the Dairy Cattle Reproduction Council (DCRC) has created synchronization protocol sheets for dairy cows and dairy heifers.
