Background: Research of hematologic and biochemical parameters in pigs is of great importance considering the factthat pigs are used as a model in research of different health disorders in humans. There are many different breeds of pigsthat have different health, productive and biologic characteristics that need to be studied. Hematologic and biochemicalvalues can vary dependent on presence of inflammation and infection. The aim of this study was to determine the influence of breed, age and their interactions on hematologic and biochemical parameters on blood of mangalitsa, mangalitsax durock and Large White pig.Materials, Methods & Results: Experiment included 10 litters of mangalitsa, white variety, mated with mangalitsa boar,10 mangalitsa litters, and white variety inseminated with durock boar and litters of great Large White inseminated withgreat Yorkshire boar. Six groups, each include 10 animals were formed and their blood was sampled (3 breeds and 2 agecategories). Age groups were formed according to moment of blood sampling. First sample was taken in moment of 30 ±5 kg of body weight. Second sample was taken when body weight was 100 kg for hematological analysis. Samples weretaken with BD Vacutainer®. Complete classic blood analysis and leucocytes formulas were done by hematology analyzerADVIA 120 Hematology Siemens, Germany. Biochemical analysis was done by biochemical analyzer A15 BioSystemwith their standard colorimetric reagents. Concentration of total protein, albumin, urea, creatinin, cholesterol, total bilirubin, AST and ALT were determined. Globulin concentration was calculated. Results have showed that hematologic andbiochemical parameters are influenced by breed, age and their interaction as: total leukocyte number (age, breed x age),neutrophils number (age, breed), number of monocytes and platelets (age, breed x age), eosinophils...(AU)
