ResumoA survey was made on a sample of 148 animals of the goat population on Canary Islands belonging to three ecotypes: Tinerfeño, Majorero and Palmero. Mean hemoglobin (Hb) concentration was 23.87 ± 0.19 g/100 ml red blood cells (RBC). Levels of erythrocyte sodium (Na) and potassium (K), and reduced glutathione (GSH) were 73.4 ± 1.49 meq/l, 30.25 ± 1.02 meq/l and 67.92 ± 1.31 mg/100 ml RBC, respectively. A normal distribution for the concentration of K and GSH in these goats was found. Mean catalase activity was higher (P<0.01) in the Palmero group (2.783 ± 0.92 IU × 104/ g Hb) than in Tinerfeño and Majorero groups (2.367 ± 0.07 IU × 104/g Hb). Differences have been found for Hb polymorphism since the Palmero group has a practically fixed allele HbA. No conclusive relationship has been found between the parameters studied: Hb polymorphism, GSH, K and catalase activity. These results suggest that the Palmero group presents differences from the other two.
