Abstract
Fowl spermatozoa were incubated in Ringer's solution at various temperatures under aerobic conditions.
Maximum motility of spermatozoa was observed at a temperature ranging between 20 and 37°C, while the vigour of motility was greatly inhibited at between 0.5-5°C and 41-45°C. Oxygen consumption of spermatozoa increased with the rise in temperature until a peak at 37°C and then was depressed by about 40 per cent at 41-45°C. The duration of motility of spermatozoa decreased progressively with the rise in temperature.
