BACKGROUND: Calf pneumonia is one of the most common diseases in dairy and beef herds. OBJECTIVES: To compare steroidal and non-steroidal anti-inflammatory drugs as adjunctive therapy in dairy calf pneumonia. METHODS: Forty calves less than six months of age diagnosed with calf pneumonia in dairy farms of Mashhad suburb were enrolled in this study based on the University of Wisconsin Calf Respiratory Scoring Chart. In this system, calves are scored based on factors such as nasal discharge, rectal temperature, cough, eye and ear staining. Calves should not have a history of any other disease. Moreover, factors such as age, sex, and severity of the disease were considered similar in distributing calves among different groups. These calves were divided into four treatment groups; all were treated with antibiotic florfenicol. The first group received dexamethasone, while dexaphenyl, phenylbutazone, distilled water were used in other groups. After 5 days, calves were examined and scored again and blood samples were taken. Complete blood count (CBC), fibrinogen, total protein, hapto-globulin and albumin measurements on blood samples before and after treatment were done. Repeated measurement ANOVA and Paired t-test were used for statistical analysis with the significance level of 0.05. RESULTS: The results showed that the degree of health, heart and respiratory rate, fibrinogen and total protein, Lymphocyte, N/L, TP-Fib/Fib ratio, MCV and MCHC significantly changed during the two sampling periods (p < /em>˂0.05), but there was no significant difference between the treatment groups (p < /em>˃0.05). Only the PCV factor and TP-Fib/Fib ratio was significant between groups (p < /em>˂0.05). CONCLUSIONS: Results indicate that in the treatment regimen of dairy calf pneumonia, the use of an anti-inflammatory drug, along with antibiotics and antibiotic treatment alone are not significantly different.
