title: Vitamin A levels of blood in collared peccaries (Tayassu tajacu) from south Texas.
abstract: Serum vitamin A concentrations were determined for 24 adult female collared peccaries from 1 captive and 2 wild populations during the period 30 January-15 March, 1983. Normal serum vitamin A concentrations of well-fed captive peccaries (mean = 39.0 micrograms/dl) were slightly higher than the reported range of values for domestic swine. Mean vitamin A concentrations of blood serum did not differ among the captive and 2 wild populations. However, a few individuals from the wild populations had low serum levels of vitamin A which suggested a possible vitamin A deficiency for these females.
