KOZA, G.A. et al. Comparación de variables morfométricas y bioquímico-nutricionales de búfalas y bubillas de Corrientes, Argentina. Rev. vet. [online]. 2017, vol.28, n.2, pp.108-115. ISSN 1669-6840.

The objective of this study was to analyze the differences in hematological, biochemical and morphometrical parameters between young and adult female buffaloes from two farms (Itatí and Empedrado) in Corrientes Province, Argentina. Sixteen Mediterranean buffaloes, 15 per category, were used. Weight and thoracic perimeter were recorded considering both geographic regions. Hematocrit, hemoglobin, erythrocyte and leukocyte counts, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration and relative leukocyte formula, were registered. Urea, total proteins, albumin, globulins, albumin-globulin ratio, cholesterol, triglycerides, calcium, phosphorous, magnesium, glucose and lactate dehydrogenase, were determined in serum. An experimental design of factorial arrangement was used, where the independent variable was the geographic region and the treatment the category, considering the interaction region x age. Descriptive statistics and analysis of variance were performed using InfoStat software. Empedrado buffaloes had higher values of live weight, total protein, neutrophils, eosinophils, cholesterol, triglycerides and urea, whereas young females had high values of lymphocytes, calcium, glucose and lactate dehydrogenase. Buffaloes from Itatí revealed higher values of weight, hematocrit, erythrocytes and cholesterol. Young females showed high lactate dehydrogenase levels. Age of animals influenced values, as adult buffaloes had higher percentages of monocytes, total proteins and globulins, while young females had higher values of leucocytes and phosphorus. Considering the geographic region, animals from Empedrado revealed higher levels of hemoglobin, erythrocytes, monocytes and magnesium. Animals from Itatí showed high protein, albumin and albumin-globulin ratio. The mean corpuscular volume and basophils were not modified. Regional biochemical reference intervals are of great importance as a tool to evaluate blood nutritional indicators and to optimize the diagnosis of diseases
