Abstract: Mastitis is a worldwide problem and of major economic threat to dairy farmers.Its incidence depends on the microorganisms, the surrounding environment and the defense mechanisms in the udder tissues and blood.In the dairy industry, both clinical and subclinical mastitis produce great economic losses.Subclinical mastitis has no apparent clinical signs but accompanied with elevation of somatic cells count (SCC) in milk.However, clinical mastitis has elevated body temperature, inappetance, a red, swollen and/or painful udder and/or abnormal milk (Huijps et al., 2008).Milk with higher SCC is positively associated with malondialdehyde level in milk (Atroshi et al., 1996;Cesa, 2004;Miranda et al., 2004;Suriyasathaporn et al., 2006), consequently more free radicals being released and a stat of oxidative stress arise (Su et al., 2002).The inflammatory reaction accompanying mastitis is generally caused by bacterial infection and results in damage to the secretory epithelium of the mammary gland and the release of cytotoxic radicals and pro-inflammatory cytokines by the phagocytic cells (Knaapen et al., 1999).
