Abstract

A clinically normal bull was submitted to the successive collection of semen. During 7 1/2 hours, the bull ejaculated 26 times and the total volume of semens collected was 94.8 ml with a total number of 85,800 millions of spermatozoa. A remarked variation was found both in the volume of semens and total number of spermatozoa. One fourth of the volume of semens was obtained between the 1st and the 6th ejaculations and the half was obtained until the 11th ejaculation. Statistically, no significant difference was found between ejaculate rank number and percentage of abnormal sperm heads.
