The breeding of buffalos is an activity in constant development in Argentina. The objective of this assay was to determine blood reference intervals in juvenile buffalos (age: 8-12 months) maintained in different areas of the northeast region of Argentina. In January 2013, thirty healthy male Mediterranean buffalos from two farms located in the departments of Itati (E1, n=10) and Empedrado (E2, n=10) from Corrientes Province and one in San Fernando (E3, n=10 from Chaco Province, were evaluated. Liveweight (PV) and thoracic perimeter (PT), as well as different hematological and biochemical parameters, were registered. Data were processed by a complete randomized block design using descriptive statistics and one-way analysis of variance (p<0.05). PV was higher in E1 and E2 compared to E3. PT was higher in E1. Red blood cells, packed cell volume and hemoglobin concentration were higher in E1 and E2. Total leukocytes were higher in E1 and E3. Total protein, albumin, cholesterol, triglycerides, HDL-C and LDL-C revealed higher levels in E3, whereas E1 registered the highest urea, calcium, magnesium and glucose levels. On the other hand, fructosamine did not reveal significant differences among groups. The highest enzymatic activities of ALP, GGT and AST were verifed in E3, but LDH was increased in E1. Such differences should be attributed to the geographical area conditions (climate, pastures) and perhaps to the handling systems of each farm. The reference intervals obtained in this work may be useful for the diagnosis of diseases and the evaluation of the nutritional state from Mediterranean juvenile male buffalos from Northeastern Argentina.
