An automatic 14-day paste diet feeder for animals

摘要

During a centrifuge experiment, any interruption that requires stopping the centrifuge may influence the results. Centrifuges often must be stopped for animal maintenance (food, water and waste removal), especially in cases of timed feedings. To eliminate the need for stopping the centrifuge while still providing timed feeding, an automatic paste diet feeder was developed. The feeder is based on a constant volume concept and can deliver a predetermined amount of paste diet at specified time intervals. This unit was supported by water delivery and waste collection systems. The entire system performed reliably and maintained the animals well for a continuous centrifugation experiment of 14 days.
