Background: recently consuming poultry meat was associated with human problems which mainly due to its fat and cholesterol content so researcher were faced by how to produce a lean meat which can be achieved through
dietary manipulating systems. Objectives: The study was designing to investigate the effect of physical feed restriction on broiler performance, cholesterol, triglycerides, and carcass-serum characteristics. Material and
Methods: The experimental work of this study was in form of a six week broiler feeding trials, in the poultry experimental unit of the Faculty of Animal Production.. 90 out of the purchased 110 day-old chicks were reared on a
deep litter floor in an open experimental house and divided in to three experimental chick groups and each group was replicated thrice and hence at random in rate of 10 chicks per pen. The control group was fed adlibitum throughout
the experimental period while the other two groups were restricted in respective during the third and fourth weeks of age to 80%, and 60% of the control group allowance then re-alimenting during the last two weeks. Results:
The experimental results indicated that the physical feed restriction was significantly decreased the overall broiler performance, provoked significant increase on liver, heart, and abdominal fat pad and thus induced a significant
improve in carcass quality by depriving the body fat toward abdominal fat and blood serum. Physical feed restriction revealed no significant effect on cholesterol and triglycerides of carcass, serum or abdominal fat pad.
Conclusions: We can conclude that lean broiler meat can be achieved through genetics, and feed manipulation (physical feed restriction).
Keywords: poultry, broiler, carcass, cholesterol, fatty acids.
