Abstract

Currently there has been a lot of interest in nutritional effects on behaviour, but the connection between diet and behaviour is still quite unestablished in dogs. This literature review presents connections between nutrition, physiology and canine behaviour, and whether canine behaviour can be regulated by altering the diet, based on current scientific literature in this field. By altering the diet, availability of precursors for hormones and neurotransmitters that controls behaviour may be regulated. Activity level is found to be affected by the fermentability of dietary fibre, energy restriction and indirectly by energy surplus. Aggressive behaviour may be decreased by low protein content and tryptophan supplement. Undesirable behaviour caused by lack of satiety is affected by dietary fibre and their fermentability. Taken together, the studies presented in this review points towards that there is a connection between nutrition, physiology and behaviour in dogs, as well as that canine behaviour can be regulated to some extent by altering the diet. However, further research is required to draw more specific conclusion on how nutrition affect canine behaviour.

Hur diet påverkar beteendet är ett aktuellt intresseområde, men sambandet mellan foderintag och beteende är fortfarande till stor del okänt hos hund. Denna litteraturöversikt är baserad på vetenskaplig litteratur och presenterar studier där samband mellan diet, fysiologi och beteende hos hund har undersökts. Hundens beteende kan påverkas genom tillförsel av utgångsämnen för beteendereglerande hormoner och signalsubstanser. Förekomst av aggressiva beteenden kan reduceras med lägre proteininnehåll och tryptofantillsatts. Hundens aktivitetsnivå har visats kunna påverkas av mängden kostfiber och energitillgång. Kostfiber och dess fermentabilitet påverkar också hundens mättnadskänsla, vilket i sin tur inverkar på oönskade beteende som uppstår vid hunger. Studierna i denna litteraturöversikt tyder på att hundens beteende till en viss grad kan regleras med förändringar i dieten. För att kunna dra mer specifika slutsatser krävs ytterligare forskning inom ämnesområdet.
