Biomarcadores bioquimicos sericos de bezerros bubalinos do nascimento aos 18 meses de idade

Abstract

The biochemical profile analysis of animals is fundamental in their clinical evaluation and determination of animal welfare, including the diagnosis of diseases. Factors such as diet, productive category, sanitary management, age and race can directly influence biochemical markers. Thus, the present study aimed to evaluate the influence of age on biochemical biomarkers of buffalo calves from birth to 18 months of age. The study was carried out at Eva Daher Abufaiad Dairy Bubalinoculture Unit Vivarium at the Federal Rural University of Amazonia, Belém, Pará. Twenty-four animals of the buffalo species were used, evaluated from birth, weekly during the first month and, from then on, monthly until 18 months. The animals underwent clinical evaluation, and after being considered healthy, the samples were collected for the following laboratory analysis: urea, total cholesterol, triglycerides, aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma glutamyl transferase (GGT), alkaline phosphatase (ALP), total proteins (EN), albumin, phosphorus, magnesium, creatine kinase (CK), iron, c-reactive protein (CRP), ferritin, chloride, fructosamine and creatinine. Several factors can interfere with the results of serum biochemical analyses, including the age grou[p and the stage of development in which the animal is. In the present study, it was possible to observe that the neonatal period is the one with the greatest influence over the results of the analysis carried out, followed by the feeding transition period, in which the calf starts to consume forage and is no longer just an infant.
