Contact time between sperm and uterus.
Additionally, it increases conception rates for some mares and/or stallions.
The Study Goals
Among the study’s goals was determining the best time interval to lavage for quelling inflammation after deep horn insemination without negatively impacting pregnancy rates. Previous studies using standard AI had demonstrated much lower conception rates if veterinarians performed lavage sooner than four hours post-breeding. While working on her master’s thesis at Universidad Nacional de Rio Cuarto, Argentina, Sofia Kovácsy hypothesized this would hold true for DHAI, as well. However, the result surprised her research team when it didn’t.
