Improving Cow FertilityThe key objectives are:
Results to date suggest that between 35 and 40% of cows in a well managed herd have prolonged “invisible” uterine infections. These cows have a conception rate of 35% to AI, compared with “clean” cows that have a conception rate of 55%. This has serious negative effects on herd reproduction status, reducing conception rate to first service across the herd to 48%. An effective treatment of this condition will improve on-farm reproductive success. |
Expected outcomes of this project
| Benefit |
| Data collated to date suggest that prolonged sub-clinical uterine infections reduce herd conception rate to first service by more than 5%. An effective treatment has the potential to improve on-farm reproductive performance. |
| Early identification of cows at risk of sub-clinical uterine infection will support early treatment and recovery from this uterine pathology, thus improving reproductive performance. |
| Results from this study have potential application to other infectious or inflammatory disorders, such as mastitis. |
