Abstract:
Breeding management in laboratory rodents is challenging, particularly around parturition and the neonatal period, where cage disturbance is often avoided in an attempt to limit neonatal mortality. Nevertheless, cage-side observations and single daily checks frequently underestimate pup numbers born and miss parturition complications.
Home Cage Monitoring (HCM) systems are gaining popularity in animal facilities, detecting critical events like food availability and activity levels. Parturition is a complex event involving specific patterns of behaviour, activity and vocalizations.
In this study, audio and video data were collected from parturition events of single-housed C57BL/6J females and breeding pairs housed in a prototype rack with integrated microphones. Vocalizations were detected during parturition in both housing conditions, with minimal vocalizations observed before parturition, except for ultrasonic sounds in pair-housed mice. After parturition, all vocalizations gradually decreased.
Despite limitations such as the need for post-event analysis and the focus on a single mouse strain, the study suggests that detecting vocalizations can be a promising basis for developing automated parturition detection. This highlights the potential of HCM systems to improve breeding management and welfare in laboratory rodent colonies.
