Measure of motivational drive for hoarding in laboratory rats.
The drive for hoarding food pellets was studied in adult female rats kept on restricted food schedule, by using varying current strength applied through the metal grid. It was observed that the rats maintained higher hoarding score at proestrus and lowest at diestrus at all strengths of currents used in the experiment indicating stronger drive at proestrus.
