Summary

WEEKLY FERTILITY LEVELS (88 TO 96%) WERE HIGHEST WITH PROCESSED, UNFROZEN SEMEN MAINTAINED AT 298 K (25C) AND CHILLED TO 288 K (15C) AT A RATE OF 0.3 K/MIN (0.3C/MIN); 4% DMSO WAS ADDED WHEN THE SEMEN TEMPERATURE WAS 298K, AND A MAXIMUM OF 40 MIN WAS ALLOWED FOR THE EQUILIBRATION. THE FERTILITY LEVEL OF HENS INSEMINATED 2 CONSECUTIVE DAYS DURING THE EARLY STAGES OF EGG PRODUCTION WITH SEMEN PROCESSED AND FROZEN TO 253 K (-20C) WAS 61%, WHEREAS THE FERTILITY OF HENS INSEMINATED WITH FROZEN SEMEN DURING THE LATTER STAGES OF EGG PRODUCTION WAS 4%.
