Abstract:The semen characteristics were studied in 182 ejaculates collected with a bovine artificial vagina from five swamp buffalo (Bubalus bubalis) bulls. The mean values were: volume, 2.9 ml; general motility, 70.7%; live (unstained) sperm, 86.5%; abnormal sperm, 10.3%; intact acrosomes, 82.4%; sperm concentration, 1.06 × 109cells/ml and total sperm/ejaculate, 3.18 × 109cells/ml. Among the sperm abnormalities noted were “knobbed” acrosome, abaxial implantation, the “Dag” defect and the corkscrew midpiece. There were no significant (P > 0.05) monthly variations for any of the semen characteristics studied.
