Food consumption and mouse-killing in Sprague-Dawley rats.
The effects of daily 10-min mouse exposure tests on food consumption were studied in killer and non-killer Sprague-Dawley rats. The results showed both mouse-killers and non-killers significantly to decrease their food consumption when tested daily for mouse-killing. The effect was more pronounced in mouse-killers than in non-killers and the day-to-day individual fluctuation of food consumption was greater in mouse-killers during the mouse confrontation period.
