Background: It is well established now that fat deposition is governed by the genetic, nutritional and management practices. However, most influenced agent in this
respect is the nutritional factors mainly phase feeding. Objectives: This experiment was conducted to evaluate the effect of phase feeding diets (starter, grower and
finisher) on broiler performance, serum-carcass cholesterol and fatty acids profile. Material and Methods: A number of 90 chicks (Ross308) from the healthy and uniform
chicks were selected and (Ross308) reared for six weeks in deep litter open house and assigned randomly to the three dietary treatments each replicated three times (nine
experimental pens, at the rate of ten chicks per pen). Treatment one consisted of one diet (starter) for all experimental period. Treatment two consisted of two diets
(starter and grower) introduced three week for each. Treatment three consisted of three diets (starter, grower, finisher) each introduced for two weeks. Results: the
phase feeding systems was significantly decreased the overall broiler performance, positive but insignificant effect on carcass parameters, provoked significant increase on
liver, heart, and abdominal fat pad, and no significant effect on cholesterol and triglycerides of carcass, serum or abdominal fat pad was observed. Concussion: The phase
feeding manipulation improved the carcass quality through elevating the cholesterol and triglycerides of the abdominal fat pad.
Keywords: Feeding, weight gain, performance, carcass.
