Chiguiro (Hydrochaeris hydrochaeris), is a wild specie considered very important to animal products in captivity conditions. It is the reason to carry out studies to increase and become stronger the knowledgeof it, in different stages of development in ex situ conditions. This is necessary to build models that include the interrelation between animal-environment-production. The goal of this study is to determine values of reference about hematology biometric, blood chemistry, enzymatic and mineral profiles in chigüiro hydrochaeris hydrochaeris, in captivity conditions. For this purpose 21 animals, of different ages and placed in three different locations, were blooding. Red and white blood cells values were obtain according with traditional methods of laboratory. The blood chemistry was processed by the blood chemistry device RA-50, that reported values of total serum proteins, albumin, creatinin, cholesterol, triglycerides, Bun, uricacid, direct and total bilirubin, alanine aminotransferase (ALT), aspartate amino transferase (AST), gamma glutamil transferase (GGT), creatine phosphokinase (CK), and electrolytes analysis such as Na+, K+, Cl-, Ca+2, PO-2. Glucose determination was made by portable glucometro. Results show that according with physiological development stage of animals, significant differences (p d” 0.05) were found to total serum proteins, white cells count, creatinin, AST and BUN. According with place of captivity, significant differences(p d 0.05) were found to mean corpuscular volume (MCV), between site one and two; MCV, BUN, uric acid, AST y K+, between site one and three; Ca+ between site three and two; The predominant cells in the differential white cells count were the neutrophiles, which presented characteristics pseudoeosinophils, reason which some authors have classified these cells like eosinophiles; The second place of white cells count, were to lymphocytes. Some parameters of chiguiro´s hematology were similar to others mammals rodent, for example: hematocrit values, with species like cotiara (Myoprocta sp), hemoglobin, like Ñeque (Dasyprocta sp), Cuy (Cricetus sp), Paca (Cricetus sp) and Cutia (Dassyprocta agouti), MCV close to Cuy (Cricetus sp) and Cut ia (Dassyprocta agouti), mean hemoglobin concentration corpuscular (MHCC), close to Hámster (Cricetus sp) and Cuy (Cricetus sp). Eosinophiles count were close to Hámster (Cricetus sp).
