Two hundred Vencob broiler chicks were randomly assigned to four dietary treatments and replicated five times. Treatments composition were; 23 percent CP in starter and 20 percent CP in finisher (T1), 19 percent CP + lysine (0.04%) in starter and 16 percent CP + lysine (0.16%) in finisher (T2), 19 percent CP + methionine (0.09%) in starter and 16 percent CP + methionine (0.03%) in finisher (T3) and 19 percent CP + lysine (0.04%) + methionine (0.09%) in starter and 16 percent CP + lysine (0.16%) + methionine (0.03%) in finisher (T4). Starter diets were fed from 3rd days after hatching to 28th days of feeding period and finisher diets were fed from 29th days to 49th days of feeding period. Significant differences were found in feed consumption and body weight gains. However, similar feed efficiency was recorded among the treatments. The highest feed consumption and body weight gains were recorded from methionine and lysine supplemented groupsof the broiler chickens.
