Actualización en los protocolos de inseminación artificial a tiempo fijo(iatf) en bovinos

Abstract

The synchronization of heat in cattle is a tool that favors farmers to increase reproductive efficiency and their profitability of the herd both as dairy and meat producing herds and the dual purpose, with the different alternatives that seek to favor and increase the profitability reducing the calving intervals and obtaining high quality genetics to obtain the best in their offspring. The use of exogenous hormones (progesterone, prostaglandin F2α, gonadotropin-releasing hormone, equine chorionic gonadotropin, estrogens, among others) favors us to have control of the estrous cycle, to carry out insemination at a fixed time (IATF) at an expected time. Today these protocols have advanced with new research and studies which favor us since it allows us to combine the different hormones to obtain high efficiency at the time of insemination (AI). In the market there are different protocols which consist of protocols based on prostaglandin and progesterone, and others a little more complex such as the Ov-Synch, Co-Synch (5 and 7) Pre-Synch and J-Synch protocols with or without modifications. All these protocols are of great importance for the different herds both as meat and milk and the dual purpose, all these protocols generating a favorable impact on reproductive biotechnology as it has great potential for genetic improvement and the reduction of the interval between deliveries.
