A simple technique for long-term intravenous feeding in unrestrained rats
Abstract:
A model for parenteral nutrition of unrestrained rats is described. Apparatus and nutrient solutions are very simple, inexpensive, and commonly available. The major survival time is at least 6-8 weeks. During the parenteral nutrition the rats gain weight and are in a excellent general health. The cumulative nitrogen balance is highly positive with a retention of 95%.
