The red-handed howler monkey (Alouatta belzebul) is one of 116 imperiled Brazilian primate species. We aimed to determine the serum biochemical profile of free-ranging red-handed howler monkeys in a highly disturbed area of the eastern Amazon.
We obtained serum samples from 26 monkeys, in which we analyzed 20 biochemical variables.
Calcium concentration was significantly lower in adult males (1.82 ± 0.25 mmol/L) than in adult females (2.10 ± 0.50 mmol/L). Both adults (males = 89 ± 85 UI/L, females = 62 ± 23 UI/L) had lower alkaline phosphatase serum activity than juvenile females (178 ± 120 UI/L). Adult male had higher levels of the direct bilirubin (13.9 ± 8.2 µmol/L) and creatinine (74.3 ± 19.4 µmol/L) than juvenile females (5.1 ± 1.4 µmol/L and 38.9 ± 15.0 µmol/L, respectively). This detailed biochemical profile may be useful for the management of red-handed howler monkeys in the wild and to support further studies at ex situ facilities.
赤面吼猴（Alouatta belzebul）是巴西 116 种濒危灵长类动物之一。我们旨在确定在亚马逊东部一个高度受干扰地区的自由放养赤面吼猴的血清生化特征。
我们从 26 只猴子中获得了血清样本，分析了 20 个生化变量。
成年雄性（1.82 ± 0.25 mmol/L）的钙浓度明显低于成年雌性（2.10 ± 0.50 mmol/L）。成年雄性（89 ± 85 UI/L）和成年雌性（62 ± 23 UI/L）的碱性磷酸酶血清活性均低于未成年雌性（178 ± 120 UI/L）。成年雄性的直接胆红素（13.9 ± 8.2 µmol/L）和肌酐（74.3 ± 19.4 µmol/L）水平高于未成年雌性（5.1 ± 1.4 µmol/L 和 38.9 ± 15.0 µmol/L）。这种详细的生化特征可能有助于野生赤面吼猴的管理，并支持在异地设施中进行进一步的研究。
