A involução uterina pós-parto e a ocorrência ou não de infecções, são fatores que influenciam a atividade ovariana e o bom desempenho reprodutivo dos animais. O objetivo do estudo foi relacionar o escore de condição corporal, estado geral, parâmetros vitais e a saúde do trato reprodutivo em vacas leiteiras à presença de infecções uterinas, buscando respostas, para a baixa eficiência reprodutiva dos animais. Foram utilizados 13 animais mestiços, onde o diagnóstico das infecções e alterações no trato reprodutivo foram realizados por avaliação ginecológica, via palpação transretal, ultrassonografia, vaginoscopia, citologia endometrial e avaliação da secreção uterina. Os parâmetros fisiológicos encontraram-se dentro da normalidade. Observou-se involução uterina significativa entre 30 e 45 dias pós-parto. A incidência de infecção uterina foi de 69.2%. Houve correlação positiva entre as variáveis: número de partos e involução uterina, grau de infecção e tempo de retorno ao cio dos animais. Já entre as variáveis: involução uterina e grau de infecção uterina observou-se correlação negativa. Apenas uma vaca retornou ao cio entre 45 e 60 dias pós-parto. A infecção uterina e o número de partos influenciaram na involução uterina e o retorno a ciclicidade nos animais.
