Abstract

This manuscript was performed to study the effect of starch and carrageenan on metabolizing energy in broiler chicks. The experiment was carried out using 120 unsexed chicks of a commercial broiler breed. Chicks were distributed into four groups, each group divided into 6 subgroups and each subgroup contained 5 chicks. All chicks were fed directly after hatching different diets as follows: chicks in the 1st group was given normal broiler diet and used as a control. In the 2nd group, chicks were given basal broiler diet containing 5% starch. Chicks in the 3rd group were given basal broiler diet containing 5% carrageenan. In the 4th group, chicks were fed on broiler diet containing 2.5% starch plus 2.5% carrageenan. Chicks in all groups were fed different diets directly after hatching until end of the experiment (7 days). The results showed that addition of 5% starch to the diet improved metabolizable energy; gave the best weight of chicks at age 7 days and significantly (P≤0.01) improved feed conversion ratio as compared with the control group and with addition of 5% carrageenan or addition of 2.5% starch and 2.5% carrageenan.
