Abstract: The effect of dietary restriction based on cassava flour and maize bran was studied on compensatory growth of 75 chick’s broiler. Aged four weeks chicks were randomly divided into three groups of 25 birds. Group 1 (control) received a diet without cassava flour and maize bran. Groups 2 and 3 received during three weeks diets containing respectively 10 and 30% of cassava flour but also 25 and 20 of maize bran. Diets 2 and 3 contained respectively 85 and 70% of the protein and energy density of the control diet. At the end of the period of food restriction, all birds were fed during four weeks at the same level appropriate to their physiological needs. After one week of food restriction, broilers of group 3 consumed with 83 g 0/head/day significantly (p<0.05) less food than those of groups 1 and 2 with 95 and 92 g, respectively. The food consumption was 123 g 116 and 107 g, respectively by broilers of groups 1, 2 and 3 at the end of the restriction period. At this time the chickens showed an average live weight of 1191, 1150 and 895 g respectively for groups 1, 2 and 3 with a highly significant difference (p<0.0001) between groups 1 and 2 on one side and the group 3 on the other. After four weeks of refeeding, chickens consumed an average of 120 g, 122 g and 108 g/head/day and weighed 2380, 2200 and 1763 g, respectively for groups 1, 2 and 3 which the growth late could not be fully compensated.
