Resumo

Na bovinocultura leiteira existem diferentes sistemas de criação, os quais podem influenciar no conforto térmico dos animais. Os bovinos, por sua vez, têm mecanismos de regulação térmica para manter a homeostase e uma zona de termoneutralidade. Entretanto, esses animais têm significativa sensibilidade à radiação solar e apresentam zonas termoneutras com temperaturas mais baixas do que a maioria das regiões brasileiras. Tal fato tem provocado grande impacto na economia leiteira devido aos efeitos negativos sobre o bem-estar, produção, reprodução e mudanças comportamentais das vacas leiteiras, além de afetar toda cadeia produtiva, desde a gestação, crescimento de bezerras e reprodução de machos. Desse modo, a presente revisão bibliográfica tem por objetivo analisar os efeitos do estresse térmico nos diversos aspectos da bovinocultura leiteira, mostrando o quão prejudicial essa pode ser.
