Inseminación artificial a tiempo fijo en bovinos utilizando semen no descongelado

Abstract

Abstract: This study evaluated the reproductive efficiency of fixed-time artificial insemination (FTAI) using unthawed semen, comparing its performance with traditional methods using thawed semen. This study was conducted at the Agricultural Station of the Universidad Técnica Particular de Loja, where cows were trained under a standardized hormonal protocol. The methodology included dividing the animals into two experimental groups according to the artificial insemination procedure using thawed and unthawed semen, evaluating parameters such as pregnancy rates, associated costs, and operational efficiency. The results showed that the use of unthawed semen resulted in a lower pregnancy rate and an increase in associated costs per calf compared to thawed semen. However, the use of unthawed semen was presented as a viable alternative to optimize resources and reduce time, improving operational efficiency in cattle and contributing significantly to sustainable agricultural practices.
