Abstract
Rectal and vaginal temperature responses of the Savanna Brown goat indigenous to the Nigerian guinea savanna were determined during the harmattan and the hot-dry season. Measurements were made at 06:00h and at 14:00h after 8h exposure to field conditions. At the 06:00h measurements during the harmattan, all animals were observed to shiver. A significant (P<0.01) positive correlation was found between rectal (Tre) and vaginal temperatures. During the harmattan, mean Tre was 38.2‡C at 06:00h and 39.7‡C at 14:00h; the mean difference, δTre was 1.5‡C. During the hot-dry season, Tre at 06:00h was 38.1‡C, and at 14:00h, 38.7; δTre was 0.6‡C. It is concluded that the harmattan is thermally more stressful than the hot-dry season and that passive thermolability may not be an important mechanism in the Savanna Brown goat in adaptation to thermal stress.
