Low fertility in dairy cattle has prompted new research evaluating intrafollicular insemination (IFI) as an alternative to common artificial insemination (A.I.) practices. IFI is based on direct introduction of sperm to a pre-ovulatory follicle.

Conducted during the summer, the European study was performed on a 50-cow dairy with low fertility. According to the research design, following estrous detection 17 cows were inseminated using IFI, and the remaining 33 cows were bred using traditional methods, depositing semen into the uterine body (IUI).

Results captured from the study include:

Four cows in the IFI group became pregnant, yielding a 23.5 percent success rate.

Three cows in the IUI group became pregnant, yielding a nine percent success rate.

On eight to 11 days post-insemination, ovulation failure was recorded in three and four cows of the IFI and IUI groups, respectively.

After analyzing results, researchers suggest that IFI could be used as a substitute procedure to the traditional breeding methods of depositing semen into the uterus in cows with low fertility.
