The role of oxygen free radicals is considered important especially during productive phases in domestic animals. To investigate the effects of the antioxidant mechanisms during different phases of milking and during dry period 5 Valle del Belice ewes were used. Blood samples were taken on days 1, 40 and 200 of milking and during dry period. Serum samples were assessed for antioxidant barrier (Oxy-adsorbent), reactive oxygen species (dROMs) and thiol antioxidant barrier (SHp). Oxidative processes increased (P<0.05) at the end of milking period, together with a compensative response of the organism to this stress and suggest the important role of oxidative status in dairy ewes.

Abstract
The role of oxygen free radicals is considered important especially during productive phases in domestic animals. To investigate the effects of the antioxidant mechanisms during different phases of milking and during dry period 5 Valle del Belice ewes were used. Blood samples were taken on days 1, 40 and 200 of milking and during dry period. Serum samples were assessed for antioxidant barrier (Oxy-adsorbent), reactive oxygen species (dROMs) and thiol antioxidant barrier (SHp). Oxidative processes increased (P<0.05) at the end of milking period, together with a compensative response of the organism to this stress and suggest the important role of oxidative status in dairy ewes.Pubblicazioni consigliate
