| Abstract: | One-hundred sixty-four gilts were artificially inseminated (AI) with frozen-thawed boar semen and, of these, 78 were immediately bred by a vasectomized boar after AI. The farrowing rate and litter size were 37.2 and 7.2 for mated gilts and 38.4 and 7.5 for control gilts, respectively. Mating by a vasectomized boar did not improve fertility or litter size. |
