temperamento, seleção, bem-estar animal, pecuáriaResumo
Na pecuária de corte, bovinos muito medrosos ou agressivos são indesejáveis e, portanto, rejeitados, fundamentalmente, por questões de produção e segurança no trabalho. É justificado que quanto mais dócil, melhor é o animal. Este artigo questiona o fato de se criar bovinos extremamente dóceis em qualquer contexto produtivo e visa abordar criticamente o temperamento como atributo funcional do sistema de produção do tipo pastoril. Sob condições agroecológicas semelhantes ao ambiente ancestral da espécie bovina, o fenótipo intermediário em docilidade contribuiria para maior aptidão biológica. Além disso, o bem-estar animal é invocado como critério a ser considerado no melhoramento genético.
