- Subclinical endometritis in New Zealand dairy cows
Subclinical endometritis is a ‘silent’ disease but can be diagnosed in research studies using uterine cytology. On average, 10% of study cows were affected five to six weeks post-calving.
- Subclinical endometritis causes poor repro performance
In this study, many cows with subclinical endometritis did not show heats nine to ten weeks after calving, took longer to conceive, and had lower conception and pregnancy rates.
- Counting the cost and treatment
The potential economic losses due to subclinical endometritis have been estimated.
- Identifying subclinical endometritis on the farm
Currently, all cows in a herd would need to be tested to identify cows with subclinical endometritis six weeks after calving. AgResearch are developing a simplified test. The treatment options for it are limited.
- Research snippets
Research highlights from the subclinical endometritis programme.
- Improving herd fertility
A poor uterine environment is a likely cause of pregnancy loss in the first three weeks of conception. This can be due to a number of genetic factors affecting early pregnancy.
- Focus on international research
Brief summaries of key international science papers recently published.
