  Title Light interference and melatonin affects digestion and glucocorticoid metabolites in striped mouse Type Journal Article
  Year 2015 Publication Biological Rhythm Research Abbreviated Journal Biological Rhythm Research  
  Volume 46 Issue 5 Pages 929-939  
  Keywords Animals  
  Abstract Animals secrete glucocorticoids to deal with daily stressors. Studies have found that supplemental melatonin decreases glucocorticoid metabolite levels in stressed animals. We determined the effect of light interference and supplemental melatonin on 1) body mass; 2) food intake; and 3) glucocorticoid metabolite levels of the striped mouse (Rhabdomys pumilio). Experiment was split into three phases: 8 L: 16 D; 8 L: 16 D with a 15 min light interruption every 4 h; and 8 L: 16 D with a 15 min light interruption every 4 h and melatonin (0.2 μg/ml) added to the water. Body mass was significantly different between phases with lowest body mass (89.17 ± 6.56 g) occurring during standard 8 L: 16 D. Light interference and melatonin significantly increased body mass. Light interference increased and melatonin decreased glucocorticoid metabolite levels. Light interference significantly increased and melatonin significantly decreased assimilation efficiencies possibly due to changes in energetic demands.
