Abstract
Sows and gilts, unselected for reproductive performance, were artificially inseminated with fresh, undiluted semen which had been stored at 7° C. in an egg yolk-glucose-sodium bicarbonate diluter for various lengths of time. The conception rates for fresh, undiluted semen, and semen stored for 1, 2 and 3 days were 56% and 55%, 5% and 42%, respectively. Number of fetuses and embryonal mortality was normal in those cases in which fresh and one-day-old semen was used. Early embryonal mortality increased when the semen inseminated had been stored for 3 days. Copyright © . .
