Semen characteristics of Muturu Bulls--Bos brachyceros.
Six mature Muturu Bulls were elecroejaculated once a week for nine weeks to study their semen quality and ejaculate characteristics. The semen volume was 1.8 ml+/-0.1, the sperm concentration 2.16x10(8)/ml+/-0.29, and the progressive sperm motility 36.2%+/-2.6. Morphologically normal sperm averaged 70.0%+/-3.1, primary abnormalities 13.4%+/-1.0 and secondary abnormalities 15.1%+/-2.3. Except in one bull, no measurable levels of fructose were observed. The contents of major cations and chloride ions in whole semen and seminal plasma were also determined.
