Title : Blood vitamin C, vitamin A, ?-carotene, ceruloplasmin, glutathione and malondial- dehyde concentrations in cows with sub- clinical mastitis treated with intramammary antibiotics

Summary : Antioxidant status (blood vitamin C, vitamin A, ?-carotene, glutathione and ceruloplasmin concentrations) and oxidative stress markers (malondialdehyde concentration) were analyzed in Holstein Frisian cows with subclinical mastitis (n = 24), the mammary infections being confirmed by CMT and bacteriological tests. According to the effectiveness of the intramammary antibiotherapy (200 mg Cephalexin and 100 000 IU Kanamycine), cows were divided into cured (n = 15, both CMT tests and bacteriological analysis of milk performed on days 14 and 21 were negative) and not cured (n = 9) (infection was still evidenced on days 14 and/or 21). Plasma MDA and blood antioxidant concentrations were determined on Days 14 and 21 post-treatment and compared with values obtained in healthy cows (n = 13). Blood vitamin C and glutathione concentrations in controls and cured cows were significantly higher than those of uncured cows. A significant rise in mean plasma vitamin A concentration was observed following intramammary therapy in cured cows, but a similar trend was also evident in the control group. No significant difference was observed in plasma ?-carotene, mal- ondialdehyde and ceruloplasmin concentrations neither between groups or in repeated samplings of individual groups. It was concluded that subclinical mas- titis significantly alters the antioxidant capacity in plasma of cows and that an efficient intramammary treatment partially restore the antioxidant status.
