Laboratory Animal Science
|October 1, 1977
Summary
The gestation period for Colombian-Brazilian squirrel monkeys (Saimiri sciureus) was determined to be approximately 147 days. This study provides key reproductive data for this primate species.
Area of Science:
- Primate reproductive biology
- Comparative mammalian gestation
Background:
- Understanding gestation periods is crucial for primate conservation and research.
- Squirrel monkeys (Saimiri sciureus) are widely used models, but specific data can vary by origin.
Purpose of the Study:
- To accurately determine the gestation length in squirrel monkeys of Colombian-Brazilian origin.
- To establish precise reproductive parameters for this specific squirrel monkey population.
Main Methods:
- Utilized a restricted mating period to control conception timing.
- Monitored ten pregnancies to record gestation duration.
Main Results:
- Gestation period ranged from 141 to 154 days.
- The mean gestation length was 146.9 days (SD +/- 3.28).
- Median and modal lengths were 146.5 and 146 days, respectively.
Conclusions:
- The typical gestation period for Colombian-Brazilian squirrel monkeys is approximately 147 days.
- This data refines knowledge of Saimiri sciureus reproductive cycles.
- Findings support accurate breeding management and research protocols.
