In the upland areas under the Royal Project Foundation the farmers have been cultivated various kind of vegetables. However, it has been found out that the most important problems followed is the environmental pollution of more than 80% from vegetable waste. Therefore, the utilization of the vegetable waste as a source of feed for livestock might be one way to reduce and solve such problems. Accordingly, the objectives of this studies were to determine the utilization of 3 foliages : Cabbage residue (CB),    Head Lettuce residue (Let) and Napier grass (Na) and 4 feed supplement : Commercial feed (Conc.), Protein block I (PBI), Protein block II (PBII) and Paddy rice (PR) in growing rabbits. The 60 crossbred (New Zealand White x Native breed) aged between 6 7 weeks were used as experimental animals. The experiment was 3 x 4 factorial designs with 2 factors, foliage and concentrate with 5 replications. The rabbits were randomly allocated into 12 treatments there were CB + Conc., CB + PBI, CB + PBII, CB + PR, Let + Conc., Let + PBI, Let + PBII, Let + PR, Na + Conc., Na + PBI, Na + PBII and Na + PR. The experiment lasted for 15 weeks. The results showed that the rabbits fed with Head lettuce residue had significantly higher final weight and average daily gain (ADG) than the rabbits fed Napier grass (2,493 4.19 and 2,086 150g and 17.1 0.51 and 13.1 1.37g, respectively) (P<0.01). The rabbits fed with Head lettuce residue had significant lower FCR than the Cabbage residue group (3.25 0.36 and 4.14 0.77, respectively) (P<0.05). The rabbits fed PBII as a feed supplement had significant higher final weight and average daily gain (ADG) than the PR group (2,426 133 and 2,196 282 g and 16.3 1.82 and 14.4 2.72 g, respectively) (P<0.05). The rabbits fed Conc. had significant lower FCR than the PB I and PB II group (3.18 0.28, 4.09 1.12 and 4.02 0.27, respectively) (P<0.05). In conclusion the Cabbage and Head lettuce residue can be used as roughages to improve the growth performance. For the feed supplement the commercial feed could be replaced by the Protein block to improve the growth performance of growing rabbits.
