Abstract
AbstractBackgroundHematologic and blood biochemical values are key tools for assessing primate health. A long‐term behavioral study of howler monkeys at a single site (La Pacífica, Guanacaste, Costa Rica), afforded the opportunity to develop baseline values for a large group of animals, evaluating differences between adult males and females and comparing to a report in the same population two decades later.MethodsIn 1998, 64 free‐ranging mantled howler monkeys were anesthetized and sampled for hematologic and biochemical analysis.ResultsBlood analysis is reported for 29 adult females, 9 juvenile females, 19 adult males and 3 juvenile males. Four adults were excluded due to external injury or disease. There were few significant differences between adult females, juvenile females, and adult males.ConclusionsBaseline blood parameters are useful for determining normal values for howler monkey populations. The values for total protein, blood urea nitrogen, glucose, liver enzymes and potassium differed from a later study in 2019 may indicate changes that are influencing howler monkey health.
