In vitro fertilization rates were determined for cryopreserved spermatozoa from control boars and boars supplemented with selenium from organic or inorganic sources. Percentages of embryos cleaved and becoming blastocysts were greatest (P < .01) for boars fed 0.3 ppm organic selenium. Dietary selenium may improve fertility of cryopreserved boar spermatozoa.
