A total of 50 does were used to determine selected hematolog.cal and biochemical parameters with special references to oxidative stress markers, acute phase protein profiles, and proinflammatory cytokines in healthy and g.ng.enous mastitis affected does. Animals were divided into two equal g.oups represented as clinically healthy （control） and diseased g.oups, respectively. The bacteriolog.cal examination of milk samples from diseased does revealed many types of bacterial infection. The isolated bacteria were Staphy/ococcus aureus （N=23/25）, Escherichia coil （N=11/25）, and Clostridium perfring.ns （N=4/25）. There was a sig.ificant increase in the levels of β-hydrexybutyrate, non-esterified free fatty acids, trig.yceride, low density lipoprotein cholesterol （LDL-C）, aspartate aminotransferase, and alanine aminotransferase and a sig.ificant reduction in the levels of g.ucose, cholesterol, and hig. density lipoprotein cholesterol （HDL-C） in does with g.ng.enous mastitis compared to healthy does. Moreover, there was a sig.ificant increase in the levels of malondialdehyde and uric acid with a sig.ificant decrease in the levels of reduced g.utathione, super oxide dismutase, and catalase in does with g.ng.enous mastitis compared to healthy does. In addition, there was a sig.ificant increase in the haptog.obin, serum amyloid A, fibrinog.n, interleukin 6 （IL-6）, IL-1β, and tumor necrosis factor-a （TNF-a） in does with g.ng.enous mastitis compared to healthy ones. Conclusively, oxidative stress biomarkers, acute phase proteins, and proinflammatory cytokines play an essential task as biomarkers for g.ng.enous mastitis in does. Mastitis may be considered as one of the ketotic stressors in does after parturition.
