2) to determine the Effect of different cassava and copra meal levels in diet from to 21 day of age on production performance, caloric efficiency and carcass characteristics of F1 (male Mia × female Luong Phuong) chicken (Study 2) These studies attempted to find answers to the specific questions presented in Chapter In Study 1, 200 day-old, F1 (Mia × Luong Phuong) chicks were randomly allotted to of treatments following a randomized complete block design (RCBD) There were replicate cages per treatment with 10 birds in each cage The treatments were used in this study were four ratios of ME to CP in diet of 150, 142.5, 135.7, 129.5 and 123.9 In Study 2, 640 day-old, F1 (Mia × Luong Phuong) chicks were randomly allotted to of 16 treatments following a randomized complete block design (RCBD) The factors that were used in this study were levels of cassava meal (0, 5, 10 and 10%) and levels of copra meal (0, 5, 10 and 15%) in booster diets There were replicate cages per treatment with 10 birds in each cage Results of Study showed that from to 21 day of age of F1 Mia × Luong Phuong chicks fed diet containing ME to CP ratio of 142.5 had the best (P0.05) cassava × copra meals levels interaction for any of the crude protein untilization parameters measured (Table 11) 61 From to 21 day of age, chicks fed with increasing concentrations of cassava meal had trend (P=0.07) and linear reduced crude protein daily intake (Table 13) Chicks fed with increasing of copra meal concentrations showed significant difference (P
