An experiment was conducted to study the
effect of different dietary fatty acid profiles on abdominal
fat deposition in broilers. Diets with four types of fats
(tallow, olive oil, sunflower oil, and linseed oil), at two
levels of fat inclusion (either 6 or 10%), were administered
to males from 21 to 42 d and to females from 21 to 49 d
of age. The sexes were studied separately. Performance
parameters, abdominal fat, muscle fat and cholesterol,
and fatty acid profile of thigh, breast, and abdominal fat
were determined. Broilers fed sunflower and linseed oils
presented better values of feed efficiency. Abdominal fat
and cholesterol content of thigh muscle were significantly lower in animals fed sunflower and linseed oils than in
those fed tallow or olive oil (P < 0.001). In females, abdominal fat increased with level of fat inclusion only in birds
fed tallow or olive oil, whereas it remained constant in
birds fed sunflower or linseed oil. Muscle fat content was
lower for birds fed tallow or olive oil but not significantly.
The fatty acid profile of the different tissues reflected
dietary fatty acid profile. Monounsaturated fatty acids
were higher in abdominal fat, whereas polyunsaturated
fatty acids were higher in muscle fat. These results suggest that polyunsaturated fatty acids produce lower abdominal fat deposition than saturated or monounsaturated fatty acids
