Precision reproduction: achieving high reproductive performance and profitability in beef cattle
Keywords:
inseminación artificial a tiempo fijo, temporada de cría, rentabilidad, resincronización, eficiencia reproductiva
Abstract
Implementing an efficient reproductive program, which combines the intensified use of timed artificial insemination (TAI) with a well-adjusted breeding season (BS), can optimize farm operations, enhance genetic potential and herd performance, and maximize production profits. Additionally, the use of resynchronization strategies and optimized TAI protocols can further improve the efficiency of the breeding system. Increasing productivity in beef cattle systems involves more than just improve pregnancy rates by the end of the BS. It’s equally important to ensure pregnant cows wean healthy and heavy calves. This requires effective farm management to minimize losses during gestation and reduce calf mortality until weaning, enhancing the weaning rate. Additionally, maximizing calf performance before weaning is key to optimizing the total kg of calf produced per cow. This review article aims to highlight the benefits of using TAI for the first service and resynchronizations, in conjunction with a well-established breeding season, in improving reproductive efficiency and profitability in beef cattle operations. Furthermore, we aim to describe the benefits of using TAI for both breeding females and their progeny, until weaning.
