Assessment of positive emotions in animals to improve their welfare.

abstract：:The purpose of the present study was to investigate the effects of a high-fat diet (HFD) in previously trained rats that have been detrained for different periods. Two groups of female rats were, first, either treadmill trained for 8 weeks or remained sedentary (Sed). Trained animals, thereafter, remained inactive for...
