Abstract:

Abstract 10.1002/zoo.10078.abs The purpose of this work was to measure important nutritional status parameters for a group of free-ranging Mexican mantled howler monkeys (A. palliata mexicana) and compare those data to published data for primates. The nutritional status of six free-ranging Mexican mantled howler monkeys was examined using biochemical analysis. Blood samples were analyzed for serum chemistry; lipids; vitamins D, A, and E; carotenoids; and minerals. Serum chemistries were somewhat different from published values, but did not indicate clear abnormalities. Circulating lipids were not different from those in captive primates. Circulating vitamin D metabolites (83±16.3 for 25(OH)D ng/mL; 563±53.8 for 1,25(OH)2D pg/mL) were similar to those in wild-caught tamarins (Saguinus oedipus), lower than some published data for captive Cebidae and Callitrichidae, and higher than for Old World primates. Serum concentrations of retinol (16.5±1.64 μg/dl) were similar to those in captive spider monkeys (Ateles geoffroyi). Retinyl palmitate and retinyl stearate was present in howler samples and may have reflected recent dietary intake. Circulating α-tocopherol (997±97.6 μg/dl) was similar to published values for other primates. Carotenoid levels in howlers were within the ranges reported for many primates. A significant finding was the presence of cadmium in samples that should be further studied. The number of individuals sampled was limited, and further investigation into the effects of seasonality is needed. However, this information provides new data for howler monkeys and for free-ranging primates in general. Zoo Biol 22:239–251, 2003. © 2003 Wiley-Liss, Inc.
