The aim of this study was to investigate the levels of acute-phase proteins and minerals as indicators for the reactivity in 1-year-old sheep. A total of 26 Chios breed sheep were fed colostrum-breast milk (control, n = 15)or were deprived after separation from their mother immediately after birth(experimental, n = 11). Mannheimia (Pasteurella) haemolytica serotype A1 was inoculated intratracheally and blood samples were taken in vacuumed sera on days 0, 1, 4, 7, 10, 13, 16, 19 and 22. Antibiotic treatment was initiated after blood sampling on day 22, and blood samples were taken on days 1, 4 and 7 after the treatment. The levels of C-reactive protein (CRP), haptoglobin, ceruloplasmin, fibrinogen, zinc, iron and calcium, which are the indicators of immune function and infectious diseases were analysed. No significant difference between the control and trial groups before and after the infection was determined. However, serum CRP, haptoglobin, ceruloplasmin and fibrinogen levels were increased in the course of the infection. These levels were restored to normal following treatment.
