This study was conducted to investigate the effects of dietary energy and protein dilution from age 8 to 14 d on growth performance, clinical blood parameters, carcass yield, and tibia parameters of broilers. Treatments were assigned in a completely randomized manner with factorial arrangement (4×4) including 4 levels of energy dilution and 4 levels of protein dilution. All birds were fed the same diet during the remaining period of time. The feeds were weighed every week, and the birds were weighed at 7, 14, and 42 d. At 14 d, blood samples were taken for clinical chemistry measurements, and 4 birds from each replicate were sacrificed to measure carcass yield and tibia parameters at 42 d. From 8 to 14 d, average daily feed intake (ADFI) of the 20% protein dilution group increased significantly compared with that of the 10% protein dilution group (P0.05). The bone breaking strength of the 15% energy dilution group decreased significantly compared with that of the 5% energy dilution group (P |
