Dietary fats influence 'open-field' behaviour of male and female laboratory mice.

Swiss mice of differing ages (juvenile and adult) and sexes were fed four specially formulated, pelleted diets containing respectively 8% saturated vegetable fat, 8% soya oil, 8% olive oil and 2% soya oil (with identities hidden from the experimenter) or a local commercial chow (3% crude fat) for 3 or 6 weeks. Subjects were individually housed and were assessed under red lighting for behaviour in a modified 'open field' (a 30 x 20 cm box with a black floor). Videotaped records were analysed using 'The Observer' system, quantifying transitions between inner and outer zones, rearing, freezing, grooming and defaecation as well as location in the two equal-sized zones.
