摘要

这项工作的目的是对所有致力于肉类生产的肉牛繁殖期延长的项目进行文献检索。在过去的20年里,在该地区国家,牛的固定时间人工授精(IATF)的使用并没有停止,这表明这是一项将继续存在的技术。它的采用曲线正处于成熟阶段,最初被最具创新性的生产商采用,如今已经被更务实或保守的生产商使用。因此,在这篇综述中,我们将强调近年来我们工作最多的协议,以及实现高妊娠率的协议。

is it possible to improve fertility with prolonged proestrus protocols? physiological bases, results and new perspectives
The objective of this work was to carry out a bibliographic search of all the programs with prolonged proestrus in the fertility of bovine cattle dedicated to meat production. The use of artificial insemination at fixed time (IATF) in cattle has not stopped growing in the countries of the region during the last 20 years, demonstrating that it is a technology that is here to stay. Its adoption curve is in a stage of maturity, having first been adopted by the most innovative and today it is already used by more pragmatic or conservative producers. Therefore, in this review we will emphasize the protocols that we have worked the most in recent years and with which high pregnancy rates have been achieved.
