Abstract
‎ The recent paper studies the impact of coccidiosis on blood levels of cattle ‎since it is one of the parasites that attack both‏ ‏poultry and cattle epidemically and ‎infect the intestine leading to big economical loss as well as high deaths of those ‎animals. Due to the few number of relevant studies that present for the this parasite ‎effect on blood level as well as the levels of anti-oxidation, Glutathione, I did such ‎the study which includes 40 cows and 35 calves of 2-3 months of age from which a ‎stool sample was taken plus a 5 mml blood sample. Next, I diagnosed the infected ‎animal through testing the symptoms of those animals and examining the stool by ‎both floating and smear methods directly to find the ovarian cysts of coccidiosis. ‎Then, I determined the level of infection (the number of parasites per 1 gm of stool) ‎by using Macmaster way so the animals were divided into two groups (infected and ‎non-infected). After that, some biochemical tests were done to check the levels of ‎Malondialdehyde (MDA) as a final outcome of lipid peroxidation using colorful ‎TBA ase and to measure the absorption of ( 450 um) ‎‏ ‏wavelength. Also, I divided ‎the Glutathione (GSH) level in blood plasma using Elmanz method.‎
