MACROSCOPIC, MICROSCOPIC AND BIO-CHEMICAL CHARACTERISTICS OF FRESH DOG SEMEN

Abstract

Forty semen ejaculates obtained from 10 healthy adult mongrel dogs by digital manipulation technique were
examined to assess the macroscopic, microscopic and biochemical characteristics. In the sperm rich fraction,
the volume (0.9 to 1.5 ml), colour (white to milky white), consistency of semen (thin to medium), overall mean
sperm concentration (319.00 + 11.79 million per ml), pH (5.80 to 6.70), initial sperm motility (80 to 90 per cent),
live spermatozoa (74 to 91 per cent), abnormal spermatozoa (7 to 10 per cent), intact acrosome (88 to 96 per
cent) and hypo-osmotic swelling response (73 to 96 per cent) were recorded. The aspartate aminotransferase
enzyme leakage into the seminal plasma ranged from 36 to 48 units per ml. The mean level of the aspartate
aminotransferase recorded was 40.00 +1.11 units per ml of seminal plasma in dog semen.
