This experiment was conducted to evaluate effect of early feed restriction on energy and protein balance in broiler chickens. One hundred and eighty broilers were distributed to four treatment group with 45 broilers for each group. Broilers were fed ad libitum through out the experiment as the control, and other three groups were fed 75% ad libitum for 5, 10 or 15 days started at 5 days of age. The present results showed that early feed restriction improved the balance of energy and protein in broiler chickens. There was negative correlation between protein retention and feed conversion ratio. Energy retention was also negatively correlated with feed conversion ratio. In conclusion restricting broiler chickens for 15 days started from 5 days of age improved the retension of protein and energy.
Key Words: Energy Retention, Protein Retention, Early Feed Restriction
