Changes of body mass and food intake in food-restricted Syrian hamsters exposed to skeleton short or long photoperiod.

Control hamsters fed ad libitum (n = 6) and food-restricted hamsters (n = 9); SP: skeleton short photoperiod; LP: skeleton long photoperiod. Data were analyzed with a mixed linear model (3-way ANOVA with repeated measures). For body mass, main effect of photoperiod: F(1,26) = 2.61, p = 0.12); main effect of feeding condition: F(1,26) = 3.98, p = 0.057; main effect of step: F(1,28) = 41.95, p<0.001; [feeding x step] interaction: F(1,28) = 49.67, p<0.001. For food intake, main effect of feeding condition: F(1,27) = 2.17, p = 0.15; main effect of step: F(1,29) = 2.37, p = 0.13; main effect of photoperiod: F(1,27) = 0.62, p = 0.44 and none interaction was significant. In a given column, groups with a different superscript (a or b) were significantly different.
