There are some studies showing supplemental tryptophan may increase serotonin production, but I'm not finding any robust and quantitative work that demonstrates a relationship to behavior (presumably diminishing aggression). Anyone know of substantive work on this?
There is a study by Farris (Farris et al. J Appl Physiol. 1998 Sep;85(3):807-16. ) that shows that infusion of trp (100mg/kg) in horses induces fatigue (they get exhausted faster during exercise).
Maybe this is of help:

Metabolic responses to oral tryptophan supplementation before exercise in horses.

Although this study did not show significant effects on behaviour it might be of interest for you:
