Extract

The most practical method for increasing the energy concentration in poultry diets has been by the addition of fats and oils (Hill and Dansky, 1954). Now a days use of fats because of increasing of the energy, improving growth and physical quality of diet have special importance. Fats rich in unsaturated fatty acids are better digested and absorbed than saturated fats (Danicke 2001). Studies with rats and broilers have reported that unsaturated vegetable oils produce lower fecal energy losses and, consequently higher metabolism energy that animal fats (Zollitsch et al, 1997). This higher metabolism energy of unsaturated fat could be expected to cause higher fat deposition because the additional energy could be stored as triglycerides (TG) in adipose tissue of fat depots. Opposite of this results Crespo and Steve (2002) observed that among broilers fed diets with added fat (tallow, olive, sunflower, and linseed), linseed oil had less abdominal fat (AF) than those fed tallow. The objective of this study was determination of effects of different fat sources on performance, blood metabolites and abdominal fat of broiler chickens.
