The suitability of bull semen for freezing, and the transmission of this character in a sire line


, : The suitability of bull semen for freezing, and the transmission of this character in a sire line. Lucrari Stiintifice, Institutul de Cercetari pentru Cresterea Taurinelor (5): 31-36

Data were obtained on 34 bulls from the same line, used at 6 AI centres (4-8 per centre). 1486 ejaculates (38-511 per centre) were examined. At the 6 stations, the post-thawing sperm motility was 29-34, 28-33, 30-41, 27-38, 20-34 and 24-34%, and the percentage of ejaculates not suitable for freezing was 8-39, 8-30, 4-50, 18-44, 5-13 and 3-22.
