Mice food demand was studied using operant chambers. Foraging costs, not price, significantly impacted food intake and meal patterns in mice.

Area of Science:

  • Behavioral Neuroscience
  • Animal Behavior
  • Nutritional Science

Background:

  • Understanding food demand functions is crucial for behavioral economics and neuroscience.
  • Operant conditioning provides a robust model for studying animal motivation and economic principles.

Purpose of the Study:

  • To establish food demand functions in mice under varying cost conditions.
  • To investigate the impact of unit price, consummatory cost, and foraging cost on food intake and meal patterns.

Main Methods:

  • Male B6/129 mice were housed in operant chambers and worked for food pellets.
  • Food demand was assessed using fixed ratio (FR) and progressive ratio (PR) schedules.
  • Procurement cost was manipulated via a nose poke response requirement.

Main Results:

  • Food demand decreased as unit price increased under FR schedules.
  • Total food intake and mean meal size slightly decreased across PR schedules.
  • Procurement costs dramatically altered meal number, while total intake changed modestly.

Conclusions:

  • Mice exhibit robust food demand functions, sensitive to different cost structures.
  • Foraging (procurement) costs have a disproportionately large effect on meal patterns compared to unit price or consummatory costs.
  • These findings offer insights into the behavioral economics of feeding and foraging in rodents.
