RODRIGUEZ LATORRE, Constanza Andrea; FLORES OLIVARES, Carlos Andrés e LUJAN FERNANDEZ, Eduardo. Selenium Determination in Goats in the Peldehue Zone, Metropolitan Area of Santiago de Chile. Rev. Med. Vet. [online]. 2021, n.42, pp.51-57. Epub 16-Mar-2022. ISSN 0122-9354. https://doi.org/10.19052/mv.vol1.iss42.6.
Selenium (Se) is a component indispensable for the antioxidant systems of animal bodies. It enables a correct maintenance and development. For this reason, a Se deficiency is associated with some oxidative disorders that result in bad health, bad reproduction and poor productive performance in general. This study aims to evaluate the Se nutritional metabolic balance by measuring the blood concentrations thereof in a farm located in Central Chile, with existing background of mortality events compatible with a Se deficiency. To do so, blood samples were taken from goats belonging to this farm (n = 32) that were subject to atomic absorption spectrophotometry at the biochemistry laboratory in the Agricultural Experimental Station, Instituto Nacional de Tecnología Agropecuaria, located in Balcarce, Argentina. Blood average Se was measured at 34.16 ± 14.81 ppb and 100% of the studied animals showed inappropriate values for this species. In the young goats (n = 5) the average value was 18.48 ± 8.51 ppb. In the adult goats (n = 27) the values were near 8.12 and 63.35 ppb. It is concluded that there is a critical Se deficiency in the sample taken from the farm located in Central Chile.
