he objective of this study was to measure the productive performance of growing rabbits as influenced by the two different level of dietary protein under three levels of branched-chain amino acids (BCAAs) supplementations. A 90-day feeding trial was conducted. A total rabbits were 72 at the age of 8 weeks were weighed when rabbits arrival at the farm and randomly distributed to six experimental groups. (G1): rabbits
fed control diet contain recommended protein level (18% CP) without any (G2 and G3 ): r abbits
fed control diet contain recommended protein (18% CP) supplemented with 2 g BCAA s /kg diet 2:1:1 and with
2 g BCAA/kg diet 3:1:2 (luecine: Iso luecine: Valine). (G4): rabbits fed control diet contain low protein level
(17% CP) without any supplementation supplementation. (G5 and G6 ): rabbits fed control diet contain low protein (17% CP)
supplemented with 2 g BCAA s /kg diet 2:1:1 and 2 g BCAA s /kg diet 3:1:2 (luecine: Iso luecine: Valine). Group rabbits fed (G3) achieved the highest significantly (P
