Abstract

Adaptation of goats to the arid and semi-arid environments may involve adjustments in erythrocyte osmoregulation. Sexual dimorphic and age-related effects on osmotic stability of the goat erythrocyte were investigated to determine physiological variations. Apparently healthy male (n = 23) and non-pregnant dry female (n = 24) Sahel goats, aged 1½–2, >2–2½, and >2½ years with mean body weights of 10.35–27.21 kg, were selected for the study from a semi-intensively managed flock. Heparinised venous blood of each goat was used to determine packed cell volume, erythrocyte count, mean corpuscular volume and osmotic fragility. Erythrocyte parameters did not vary with sex or age of the animal. Erythrocyte osmotic fragility (EOF), determined in hypotonic buffered saline, did not show sexual difference, but age elicited significant (p 1½–2 years, respectively. Body weights increased (p
