Abstract

The concentration of erythrocyte reduced glutathione (GSH) was studied in Sayaguesa cattle (n=1 50) and in two populations ofAvileña-Negra Ibé¬rica cattle, referred to as A-NI 1 (n=141) and A-NI 2 (n=141). Variation, but not polymorphism, was found for GSH content in any of the groups examined. Moreover, the frequency distributions did not significantly deviate from normality. Mean values of glutathione levels were 54.61±1.71 mg, 66.66±1.67 mg and 64.41±1.74 mg/100 ml red cells in A-Nl 1, A-NI 2 and Sayaguesa cattle, respectively. Significant differences in GSH content were detected between the two populations analysed of Avileña-Negra Ibérica, whereas GSH level in one of those populations (A-NI 2) did not significantly differ from that of Sayaguesa cattle.
