The article features Fernanda Ambrosino, a veterinarian and member of Ceva Saúde Animal's technical team, who discusses the benefits of biotechnology, specifically fixed-time artificial insemination (IATF), in Brazilian livestock farming in the Giro do Boi series 'The Protagonist'. IATF is a technique that synchronizes insemination in females, leading to managed births, standardized carcass quality, and higher market value animals. Despite advancements, there is still potential for growth, especially in zebu cattle. Ambrosino emphasizes the cost-effectiveness and benefits of IATF, such as genetic improvement and increased production. The series aims to highlight the crucial role of women in agriculture and the importance of biotechnology in enhancing the efficiency and modernization of Brazilian production systems.
