Egg Albumin Supplementation Decreases IsolationInduced Aggression in Male White Mice
Francisco S. Legario | Maureen Antonette D Bereber
Abstract:
There is a need to search for solutions of minimizing aggression so as to minimize
violence. The purpose of the study is to determine the effects of different levels of egg
albumin supplementation to the aggressive behavior of male white mice ( ). Mus musculus
Specifically, this study aimed to describe aggressive tendencies by isolation-induced
fighting of male white mice when fed different levels of egg albumin; determine aggressive
behavior in terms of the number of attacks and body scars when fed different levels of egg
albumin; and measure dominant-subordinate status when fed different levels of egg
albumin. White mice were chosen as test animals since they have homologous genes coding
with humans. Furthermore, aggression tends to be more common among male mice than
female mice. T-test results showed that there is a significant difference in the aggressive
behavior between the treated and untreated mice in all treatments except for Treatment D
(negative control) in terms of number of attacks and body scars and a significant difference
in all treatments in terms of the dominant-subordinate status. Analysis of Variance
(ANOVA) showed a significant difference in the number of attacks and the dominantsubordinate status. Overall, results showed that egg albumin supplementation reduced
aggression in male white mice regardless of the level of egg albumin. It was concretely
shown that treatments fed with varied levels of egg albumin significantly alleviated
aggressive behavior compared with treatments without egg albumin supplementation.
