The behaviour of the levels of glutathione (GSH) and hemoglobin (Hb) was studied in blood samples from 126 one- to<br />seven-year-old sheep reared in the province of Salerno, Italy. Negative and significant correlation with age both for<br />hemoglobin and glutathione has been reported. A significant difference, on the basis of age, is evidenced only in males<br />(n=24) for Hb (P = 0.001) and only in females (n=102) for GSH (P = 0.001). These results indicate a greater presence<br />of Hb in young sheep and a greater demand for GSH in adult sheep. Moreover, the lowering of GSH and Hb with respect<br />to age may have caused a reduction of the organism defense to environmental stress factors. Therefore, it would be useful,<br />at least in productive animals, to use feed with a high content of polyphenolic compounds that increase the GSH concentration.<br />The aim of the present work was to study the behaviour of the levels of glutathione and hemoglobin in sheep at different<br />ages.
