The effect of iron supplementation in the diet of Dasypus novemcinctus (Linnaeus, 1758) armadillos in captivity

Armadillos of the species Dasypus novemcinctus have been used as an experimental model of leprosy. Besides non-human primates, they are the only species naturally infected with Mycobacterium leprae and when experimentally inoculated, reproduce the lepromatous form of the disease producing large quan...

description Armadillos of the species Dasypus novemcinctus have been used as an experimental model of leprosy. Besides non-human primates, they are the only species naturally infected with Mycobacterium leprae and when experimentally inoculated, reproduce the lepromatous form of the disease producing large quantities of bacilli. This species has been maintained in captivity by numerous researchers and specific housing and feeding requirements have been developed to guarantee their survival during long experimental periods. In the "Lauro de Souza Lima" Institute, armadillos receive dog food, ground beef, boiled eggs and vitamin C. However, despite the balanced diet, anemia has been observed in some captive animals, especially in armadillos inoculated with M. leprae in advanced stages of infection. Thus, the objective of the present study was to evaluate the effect of iron sulfate supplementation in the feed provided for armadillos, both inoculated and non-inoculated with M. leprae, by means of the evaluation of their hematological profile. Fourteen armadillos received 10 mg/animal of iron sulfate (Hematofer®) diluted in sterile water mixed with their daily feed for 50 days. Hemograms and serum iron dosages for each armadillo were performed before and after supplementation. The hematocrit values increased significantly after iron supplementation, both in armadillos inoculated and non-inoculated with M. leprae. It is possible that the amount of iron in the feed is insufficient for the formation of hemoglobin, leading to microcytic anemia. Dietary supplementation with iron sulfate reversed this state, showing the importance of understanding the metabolism of exotic species for their maintenance in captivity, and thus ensuring their well-being.
