The output of spermatozoa in male farm animals. I. An attempt to determine the daily production of spermatozoa on the basis of the so-called exhaustion test carried out, using an artificial vagina, at different intervals of time in stallions, bulls and rams.

Roczn. Nauk rol. B, 83: 411-423



Depletion tests were carried out at intervals of 1-20 days. The number of ejaculations per test averaged 20.6 (1-41) for bulls and 3.8 (1-10) for rams. For stallions it was 2.9 (1-10) and 2.5 (1-7) in 2 series of tests. The number of spermatozoa produced per test (x 109) averaged 12.6 (0.5-27.6) for bulls and 9.8 (l.0-27.4) for rams. In horses it was 20 (3-58) and 21 (2.5-63.6).
