Primate disease and breeding rates

Area of Science:

• Primate research
• Comparative biology
• Laboratory animal science

Background:

• Understanding health and demographic patterns in captive primate populations is crucial for welfare and research.
• Variability in birth, illness, and death rates among species can impact colony management and study outcomes.

Purpose of the Study:

• To compare birth, illness, and death rates across 33 primate species.
• To investigate correlations between these demographic factors and species popularity over three years of laboratory housing.
• To identify species with particularly high or low rates in these categories.

Main Methods:

• Comparative analysis of demographic data (birth, illness, death rates).
• Data collected over a three-year period for 33 distinct primate species.
• Statistical examination of correlations between rates and species popularity.

Main Results:

• Low correlations were observed between species popularity, birth, illness, and death rates.
• Highest birth rate: Macaca nemestrina. Highest illness rate: Pongo pygmaeus. Highest death rate: Cercopithecus aethiops.
• Lowest birth rate: Lemur catta. Lowest illness rate: Sanguinus mystax. Lowest death rate: Galago crassicaudatus. Galago crassicaudatus and Macaca fascicularis exhibited low disease and high birth rates.

Conclusions:

• Primate species exhibit diverse demographic profiles in laboratory settings.
• Species-specific factors influence birth, illness, and death rates independently of popularity.
• Galago crassicaudatus and Macaca fascicularis may serve as models for low disease incidence and high reproductive success.
