Subcutaneous Immunization with Inactivated Bacterial Components and Purified Protein of Escherichia coli, Fusobacterium necrophorum and Trueperella pyogenes Prevents Puerperal Metritis in Holstein Dairy Cows

Subcutaneous Immunization with Inactivated Bacterial Components and Purified Protein of Escherichia coli, Fusobacterium necrophorum and Trueperella pyogenes Prevents Puerperal Metritis in Holstein Dairy Cows

In this study we evaluate the efficacy of five vaccine formulations containing different combinations of proteins (FimH; leukotoxin, LKT; and pyolysin, PLO) and/or inactivated whole cells (Escherichia coli, Fusobacterium necrophorum, and Trueperella pyogenes) in preventing postpartum uterine diseases. Inactivated whole cells were produced using two genetically distinct strains of each bacterial...

Diagnosis and treatment of acute puerperal metritis in dairy cows

A longitudinal cohort study of acute puerperal metritis cases in Swedish dairy cows

BACKGROUND Acute puerperal metritis affects cows during the early postpartum period and causes fever, fetid vaginal discharge and general depression. The disease is severe and treatment with antimicrobials is often required. This study followed 79 Swedish dairy cows with acute puerperal metritis with registered treatment and outcome in terms of recovery. Bacteria isolated from the uterus and th...

Effect of Puerperal Metritis on Holstein Cows Productive, Reproductive Variables and Culling Rates

The objective of the study was to determine the effect of puerperal metritis prevalence in high yielding Holstein cows on productive (305 days, actual milk yields), reproductive (days to first estrus, days open and services per conception) variables and culling rates. Throughout the study, 2885 dairy records were collected from high yielding private Holstein dairy farm (average milk yield was u...

Rectal temperature, calving-related factors, and the incidence of puerperal metritis in postpartum dairy cows.

The objectives of this study were as follows: 1) to evaluate the association among abnormal calving, parity, and season on the incidence of puerperal metritis (PM) and clinical endometritis (CE) during d 3 to 13 and 20 to 30 postpartum, respectively; 2) to describe the rectal temperature (RT) of cows with PM before diagnosis; and 3) to document associations among PM, CE, and reproductive perfor...
