     A pilot assessment program was initiated at the Yerkes National Primate Research Center Field Station to determine annual clinical and developmental baselines for males going into breeding groups, as well as to assess their current health status in order to maximize both reproductive success and well being. In 2017, 42 males (ages: 6-16) were evaluated beginning at the onset of the breeding season. Various morphometics as well as housing configurations and social rank were recorded. Blood samples were collected for clinical measures and eventual hormone analyses. Findings: Older animals were larger and had higher Body Condition Scores (BCS) (P<0.05) Multivariate analyses also demonstrated that run-housed breeding males had significantly higher BCS than males in compound-based multi-male breeding groups and run-housed multi-male bachelor groups (P<0.05). Dominance status was significantly related to age (P<0.05) but not to any other variable. During the study, three inguinal hernias were detected and repaired. Dental issues, including broken or missing canines were detected and scrotal scarring was also discovered in three males, which may reflect testicular scars. These health assessments were also valuable since they provided a systematic evaluation of male clinical condition prior to the breeding season, which can provide insights into how male condition changes during breeding season and over time. Finally, the detection and/or correction of clinical conditions may positively impact reproductive performance and ultimately reproductive success.
