Will A.I. be Going Deep?
By Tyler Kelley, Pork Magazine - Intra-uterine insemination, or deep insemination, could let you reduce the amount of boar sperm per dose, but it???s uncertain how beneficial it can be in the long run.
IUI refers to a method of artificial insemination, in which a special catheter is manipulated 10 to 14 inches deeper into the sow???s cervix than normal, until it reaches the uterine cavity.
Despite being pegged as an up-and-coming technology, IUI has not caught on in the United States. Less than 1 percent of all artificial inseminations are done via IUI, says Kevin Rozeboom, research and education director for Minitube of America. That number is not expected to increase greatly unless some things change.
???Semen costs and reproductive performance will determine the future of IUI,??? says Don Levis, Extension swine specialist, Ohio State University. ???If semen cost is increased and reproductive performance is similar to traditional A.I., it is not beneficial to use IUI. If semen cost is lower and reproductive performance is similar to traditional A.I., it is beneficial to use IUI. If you collect your own boar???s semen, at a lower cost per dose compared to purchased semen, then IUI might be economical.???
