This study aimed to determine the digestibility of crude protein, calcium and phosphorus retention in rations using gamal leaf and cekuti leaf flour on grower turkey poults. Animals used were 8 weeks old turkey, totaling 100 unsex. The study used a randomized block design (RBD) using 5 treatments and 4 groups. Grouping was based on body weights; group 1 has a weight of 725 - 849 grams, group 2 has a weight of 850 - 974 grams, group 3 has a weight of 975 - 1099 grams, group 4 has a weight of 1100 - 1224 grams, each group consisting of 25 turkeys. The treatments given include T0 = without any gamal and cekuti given, TI = giving rations with 5% gamal, T2 = giving rations with 10% gamal, T3 = giving ration with 5% of cekuti and T4 = givingration with 10% of cekuti. The data obtained were carried out by the F test and Duncan's multiple range with a level of 5%. The results showed that the use of gamal leaf flour and scruff on the ration for grower turkey had a significant effect (P˂0.05) on crude protein digestibility, calcium and phosphorus retention and in grower turkey. The conclusion is that as much of 5% gamal leaf flour can be used in turkey rations.
