Summary

EJACULATES FROM 10 BULLS WERE SPLIT AND PROCESSED IN EGG YOLK-CITRATE-GLYCEROL, EGG YOLK-TRIS-GLYCEROL, AND WHOLE MILK-GLYCEROL. ALL SEMEN WAS PACKAGED AND FROZEN IN 5 ML FRENCH STRAWS AT 77 K (-196 DEG C). SEMINAL QUALITY IMPROVED WITH INCREASING FINAL SEMINAL TEMPERATURE UP TO 304 K (31 DEG C) AND DID NOT DIFFER BETWEEN 304 AND 317 K (31 AND 44 DEG C) FOR ANY OF THE EXTENDERS. A THAW RATE OF 3 K/SEC RESULTED IN INFERIOR QUALITY FOR ALL EXTENDERS, AND RATES 11, 19 AND 27 K/SEC RESULTED IN SIMILAR QUALITY FOR CITRATE AND MILK EXTENDED SEMEN.
