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.
1983年1月30日至3月15日期间，测定了来自1个圈养种群和2个野生种群的24只成年雌性领西猯的血清维生素A浓度。营养良好的圈养西猯的正常血清维生素A浓度（平均值 = 39.0微克/分升）略高于报道的家猪维生素A浓度范围。圈养种群和2个野生种群的血清维生素A平均浓度没有差异。然而，野生种群中的一些个体血清维生素A水平较低，这表明这些雌性可能存在维生素A缺乏的情况。
