Abstract:
(1) Nine successive ejaculates were collected from each of four Merino rams on three occasions at intervals of three days. The mean time intervals between successive ejaculates on the first, second, and third collecting days were respectively 41, 28, and 30 min. Aliquots from alternate ejaculates (first, third, fifth, seventh, and ninth) were cold-shocked before and after 1 : 4 dilution with an egg yolk
