The effect of early feed restriction on metabolic programming and compensatory growth was studied in broiler chickens. A total 480 female 1-d-old birds (Aconred) were randomly allocated to ad libitum feed-restricted groups, each which replicated 6 times with 40 per replicate. Broilers provided commercial diets. Feed-restricted broilers deprived for 4 h day from 1 21 d age. Effects treatments determined at 63 In age, BW, average daily gain intake, breast muscle (P < 0.01), carcass yield 0.05), abdominal fat 0.05) decreased. Ether extract content increased whereas CP slightly Triiodothyronine 0.01) thyroxine decreased serum. Free fatty acid very low density lipoprotein serum, triglyceride glucose 0.01). Activities NADPH-generating enzymes liver including malic dehydrogenase, isocitrate glucose-6-phosphate remained unchanged birds, hormone-sensitive lipase activity gain, yield, serum triiodothyronine as 0.05). significantly increased, except dehydrogenase fat. Lipoprotein summary, severely affected performance lipid metabolism the period. Because there no statistical difference among final near full achieved. addition, might have induced prolonged chicks led adult obesity.
