Avaliação genética, Dados zootécnicos, SeleçãoResumo
A educação e a capacitação de produtores constituem estratégias fundamentais para ampliar a aplicação do melhoramento genético animal nos sistemas de produção. Trata-se de uma revisão bibliográfica de caráter didático, que reúne conceitos e exemplos práticos voltados à capacitação de produtores. O conhecimento dos fundamentos do melhoramento permite compreender os princípios da seleção e o uso adequado das informações genéticas. Nesse processo, a realização de registros zootécnicos e a qualidade dos dados assumem papel essencial, pois fornecem informações confiáveis para as avaliações e para a tomada de decisões. Além disso, a capacitação favorece a interpretação dos resultados das avaliações genéticas e sua aplicação na escolha de animais, acasalamentos e estratégias de seleção. Dessa forma, ações educativas e de capacitação podem aproximar o conhecimento técnico da realidade dos produtores, contribuindo para o uso mais eficiente das ferramentas de melhoramento genético animal dentro dos rebanhos.
