Electrolytic and hemogasometric parameters for female agoutis (Dasyprocta prymnolopha Wagler, 1831) raised in captivity

Abstract

Agoutis (Dasyprocta prymnolopha, WAGLER 1831) have been studied in captivity as a potential source of meat for rural populations in Brazil, as a way of providing low-cost protein and easing hunting pressures in local communities. However, little is known about their physiological blood markers, which are crucial for animal husbandry and effective welfare management. This study provides hemogasometric and ionic venous parameters for female agoutis raised in captivity in the drylands of Brazil. Venous blood samples were collected from six females and analyzed for dissolved gases and ions in the blood. Hemogasometric parameters, especially base excess and anion gap were generally heterogenous, while ions varied little among individuals. Moreover, we observed high chlorine values and negative base excess values, which suggest that some animals might be implementing compensatory mechanisms for ion imbalances. We provide a preliminary note on agouti venous gases and ions, while reiterating the importance of the clinical context and in-house parameter definition to maximize accuracy.
