Abstract
The objective of this thesis was to review important topics related to uterine diseases in dairy cows and highlight a project conducted as part of the MS program that aimed to evaluate the differences in lactational performance associated with antimicrobial therapy and clinical cure of metritis in dairy cows. In this study, data from two randomized controlled trials consisting of 4,744 Holstein cows from 5 dairy farms in California, Florida, and Texas was used. Five groups composed this study, clinically cured cows that received ceftiofur (CEFC); not cured cows that received ceftiofur (CEFN); clinically cured cows that did not receive ceftiofur (NTC); not cured cows that did not receive ceftiofur (NTN); cows without metritis (NMET). Risk and time of pregnancy and culling, total milk production by 300 days in milk were assessed across groups. Overall, clinical cure of metritis was positively associated with milk production and reproduction, regardless of antimicrobial therapy, warranting further investigation regarding selective therapy of metritis.
