A case of metritis is estimated to cost producers between $304 and $354 from losses in production and performance, according to research from veterinarian Michael Overton of the University of Georgia.
Among Overton's findings:
- Costs from culling within the first 60 days of milk are estimated at $71 per case. Cows affected with metritis have an increased culling risk of 4.2% during the first 60 days in milk.
- Cows diagnosed with metritis average 4.9 fewer pounds of daily milk production for the first 120 days post-calving. Total losses from all cows due to declines in milk production because of metritis are $77 per case.
- Metritis causes a depression in fertility, resulting in an increase of 18 days open and a decline in the 21-day pregnancy rate of 3 to 6 percentage units. Costs associated with a decrease in fertility and reproductive performance due to metritis are estimated at $98 per case.
- Treatment costs and associated milk withdrawal range from $58 to $108, depending on the antibiotics chosen.
A 1,000-cow dairy with a typical incidence rate of 22% is losing $66,000 a year due to costs associated with metritis.
