Avaliação da inseminação artificial em tempo fixo (IATF) em bovinos Revisão bibliográfica e análise de resultados reprodutivos na bovinocultura

Abstract

Objective: To analyze the effectiveness and applicability of Fixed-Time Artificial Insemination (FTAI) in cattle breeding, highlighting its impacts on reproductive efficiency, genetic improvement, and productive profitability. Methodology: The research was conducted between March and May 2025, following a qualitative anddescriptive approach through a bibliographic review of scientific articles, books, and electronic journals in Portuguese, English, and Spanish. Databases such as SciELO, Google Scholar, and Veterinary Medicine journals were consulted. In addition, data collected during the supervised internship at Fazenda Laranjeira, in Rio Verde (GO), were used to analyze pregnancy rates and reproductive efficiency in practice. Results: It was observed that FTAI enables higher conception rates, concentrated calving, and genetic advancement of the herd, showing an average pregnancy rate of 42.53% in the evaluated data—values consistent with those reported in the scientific literature. Conclusion: It was concluded that FTAI represents an effective and economically viable technique for reproductive intensification and genetic improvement in cattle herds, provided it is performed with proper management, planning, and technical training.
