The aim of the research was to evaluate serum copper concentration and superoxide dismutase activity (SOD) in the erythrocytes of cows with clinical mastitis. Forty-four cows were divided into four groups: A, B, and C with clinical form of mastitis caused by Staphylococcus aureus, Streptococcus agalactiae, and Escherichia coli, respectively, and healthy control group D. Copper concentration was determined...
Prooxidant and antioxidant processes and diseases of cattle resulting from decreased bioavailability, or redundant copper in animal feed are often connected to biogeochemical and antropogenical factors. Therefore, it is very important to include biogeochemical and antropogenical zones in which animals were raised while analysing the bioavalibility of trace elements in feeds and the disturbances in...
