Resumen:
Quantifying circulating nutrient concentrations in sera of free-ranging
subjects will help to establish a basis from which we can evaluate the nutritional
status and needs of the captive population. We collected serum samples from 26
free-ranging black-and-gold howlers (Alouatta caraya) in San Cayetano forest in
northern Argentina. We analyzed them for concentrations of lipoproteins; amino acids; vitamins A, D, and E; carotenoids; and minerals. There are a few significant
differences between sexes in concentrations of high-density lipoprotein cholesterol,
certain amino acids, vitamin E, lutein + zeaxanthin, and copper. Most nutritional
parameters are similar to the ones measured in free-ranging Mexican mantled
howlers (Alouatta palliata mexicana) and in captive New World primates (NWPs).
Carotenoid, vitamin D, and phosphorus concentrations are the exceptions.
Carotenoid concentrations are higher in free-ranging Alouatta caraya than reported
for other free-ranging and captive species. Vitamin D concentrations are 14 times
greater in the free-ranging black-and-gold howlers than in captive NWPs.
Phosphorus concentrations are also higher than expected and higher than typically
occur in captive primates, leading to a 1:1.6 calcium:phosphorus ratio. Because we
based our study on a small number of free-ranging howlers, additional samples from
different regions and throughout the year would better define desirable nutritional
parameters for captive howlers.
