Food & Liquid Intake

Quantitative assessments of food and water intake are delicate experiments that must balance competing constraints, namely the requirement for a special measurement setup with the impact of the setup on mouse behaviour (and the mesurements themselves). Methods of measurement available at MEF include:

  • Mid-long term measurement of feeding and feeding control (pair feeding) online with the Phenomaster (TSE) system (24 cages),
  • Short term feeding and drinking measurements in metabolic cages.

Mice are always singly-caged for such measurements, which requires an acclimatation period. All methods are labor-intensive, and their choice will depend on the expected type of data (see below).

Long-term, cumulative feeding measurement and control in the Phenomaster (TSE) - 24 cages

The most accurate assessment of food intake in energy balance studies requires cumulative measurements over weeks of both food disappearance and food spillage. Mice are in singly-caged in home cages. The system allows for:

  • the cumulative measurement of food intake over weeks
  • the control of food intake (by time, quantity, and pair feeding)

Short term feeding and drinking measurements in metabolic cages

Food intake and water intake can be assessed as well in experiments involving metabolic cages for:

Metabolic cages are however not native cages, and can therefore not be used to host mice for more than a few days.
