Fat taste is one of the taste types with high potential implications relevant to the poultry industry. The utilization of dietary fat in poultry diets has attracted a lot of attention for many years. However, relatively little attention has been paid to the fact that addition of fat to low fat diets increases intake in chickens even when the caloric content of the diet is kept constant (Klasing, 1998b). This phenomenon appears to be due to palatability. Similarly, Furuse et al. (1996) showed that gustation plays a key role in determining oil preferences in chickens. It has become apparent recently in mammals that one of the widely accepted novel primary taste types is fat sensing and the candidate taste receptors have been identified (Cartoni et al., 2010). Similar to other taste types, no homolog avian gene has been verified, however, predicted genes can be found in the chicken genome databases.
