The effect of intrauterine infusion of dextrose on clinical endometritis cure rate and reproductive performance of dairy cows (original) (raw)

2015, Journal of dairy science

The main objective of this study was to evaluate the intrauterine administration use of 200 mL of 50% dextrose solution as a treatment against clinical endometritis (CE); CE cure rate and reproductive performance were evaluated. Additionally, the association of several relevant risk factors, such as retained placenta (RP), metritis, CE, anovulation, hyperketonemia, and body condition score with reproductive performance, early embryonic mortality, and CE were evaluated. A total of 1,313 Holstein cows housed on 4 commercial dairy farms were enrolled in the study. At 7 ± 3 DIM cows were examined for metritis and had blood collected to determine serum β-hydroxybutyrate concentration. To determine if cows had ovulated at least once before 44 ± 3 DIM, the presence of a corpus luteum was evaluated by ovarian ultrasonography at 30 ± 3 DIM and at 44 ± 3 DIM. At 30 ± 3 DIM, CE was diagnosed using the Metricheck device (SimcroTech, Hamilton, New Zealand); cows with purulent or mucopurulent vag...
