Abstract

Uterine health disorders are common in dairy cows and result in reproductive inefficiency and economic loss in dairy herds. Specific uterine bacteria associated with some uterine health disorders have been described. However, information regarding the relationship between calf birth weight and uterine bacteria is lacking. The aim of this study was to evaluate relationships between uterine bacterial isolates during the first four weeks after calving, uterine health disorders (metritis, retained placenta [RP], clinical and subclinical endometritis), fever and calf birth weight. The impact of uterine health disorders on reproductive performance was also evaluated.
