Summary and Implications
The objectives of this study were to determine the effects of artificial insemination (AI) catheter type on litter size and farrowing rate. No performance difference was found between sows artificially inseminated using intrauterine or intracervical methods. Since intrauterine catheters typically are more expensive, there is an economic advantage for the more commonly used intracervical method of artificial insemination in the present study.
