Literature research has revealed that undesirable behaviour among boars can possibly be reduced by modifying the composition of their feed. The study was commissioned by the Ministry of Economic Affairs and the Productschap Vee en Vlees [Product Board for Livestock and Meat] and was conducted by Prophys Animal Science Consultancy as part of the five-year project a�?Stopping the castration of boar pigletsa��.
The literature research inventoried knowledge concerning hormonal and neuro-endocrine regulation of boarsa�� uncontrolled behaviour. It also inventoried the options for reducing this behaviour by changing the composition of the feed. The neurotransmitters dopamine and serotonin play an important role in the expression of undesirable behaviour. Extra tryptophan in the feed stimulates the production of the latter in the brain and can supress aggressive (and very probably also sexual) behaviour.
