Automated food & liquid access control

Driven by small software-controlled servo motors, shielding cylinders can be independently moved up and downwards. If the cylinder is lowered, the access port of the food container or access to the nipple of the drinking bottle is blocked, restricting access to food and/or liquid according to customized schedules – by time, duration and by amount consumed. Combined with a running wheel or operant wall, food/liquid access can be linked to performance parameters.

Key features

  • fully automated food and liquid access control by time, duration and amount
  • food or liquid restriction or deprivation prior to learning tasks raise motivation – ideal in combination with the operant wall
  • controlled administration of drugs in food or liquid form
  • paired and yoked feeding* and drinking experiments can easily be implemented

*Paired / yoked feeding

In a paired feeding paradigm, each animal from the test group is paired with an animal in the control group. The control animal will be fed the same amount of food that the test or “master” animal has consumed. In yoked feeding experiments, the master/test animal not only imposes the amount but also the time pattern of food consumption onto the control animal, thereby creating highly physiological control conditions.

The TSE PhenoMaster home cage system provides sophisticated technology to simplify and automate your paired/yoked feeding experiments: we offer simultaneous multiple cage control, high-precision weighing stations to quantify the amount of food consumed, as well as fully automated access control units that limit food availability by time, duration and amount consumed.
