Abstract: The aim of this study was to determine the performance of Luong Phuong broilers with basal diets supplemented with cassava, leucaena leaf meals and stylosanthes grass meal (CLM, LLM and SGM). The study used 630 birds, from 14 – 70 days of age, allocated into 7 treatment groups. The treatment groups were named as follows: The control (CG), 1A, 2A, 3A and 1B, 2B, 3B. Birds in the control group were fed with a basal diet without the inclusion of leaf meal. The metabolic energy and crude protein levels were complied with nutrient requirement standards for colored feather broilers. Diets were prepared for birds in 1A, 2A, 3A with the addition of CLM (1A), LLM (2A), and SGM (3A). ME and CP levels in these diets were adjusted to achieve the standard recommendation so that they were similar to that of the control (Addition or the 1st method). Diets prepared for birds in groups 1B, 2B, 3B with the replacement of leaf meal in the basal diet without taking into account ME and CP levels (Replacement or the 2nd method). The results showed that: i) Diets with the inclusion of leaf meals had significant effect on broiler’s performance in comparison with that of the control diet, ii) inclusion of CLM had more positive effect than the inclusion of LLM, and inclusion of LLM had more effect than that of SGM, iii) Addition of leaf meals into the diet with adjustment of ME and CP levels had more significant effect on bird’s performance than that of the replacement method without ME and CP level adjustment. However, CLM and LLM can be supplemented into diets in either addition or replacement, but SGM should be added into diet with adjustment of ME and CP levels.
