N2  - A factorial experiment (4 x 2) was carried out includingfour levels ofcom distiller dried grain with solubles (DDGS) (0,16,22 and 28%) and two levels ofsupplemental enzyme (0.0 and 0.5 gm/ Zylam kg diet). A total number of 96 New Zealand( NZW) rabbits at 5 wks old were weighed and randomly distributed into the 8 treatment groups (12 rabbits, each) in three replicates (4rabbits, each). Growth peiformance, economic efficiency, apparent digestibility and carcass traits as well as blood plasma constituents were studied during the growing period (5-14 weeks). Results show that no significant differences in live body weight ( LBW), body weight gain (BWG) andfeed intake (FI) were observed by different levels of inclusion DDGS, enzyme supplementation or the interaction between their in rabbit diets except BWG during 12-14 weeks ofage, which it was significantly (P<0.05) improved byfeeding different levels ofDDGS. Inclusion of22 and 28 %DDGS in growing rabbit diets hadsignificantly improvedfeed conversion ratio( FCR), protein efficiency ratio( PER) and peiformance index( PI) as compared with the control during the whole experimental period. However, increasing DDGS to 22 or 28% in growing rabbit diets significantly decreased energy efficiency utilization (EEU) as compared with the control during overall experimental period. Economic efficiency (EEF) % were affected by DDGS inclusion during the whole experiment period, group ofrabbits fed diets containing 28% DDGS exhibited the best EEF value as compared to control diets. All digestibility coefficient of nutrients and nutritive value were insignificantly improved by DDGS , enzyme supplementation and their interaction. Eviscerated carcass, total edible parts and abdominal fat percentages were insignificantly higher by increasing DDGS and enzyme addition levels as compared to control diets during the growth period. The DDGS had no significant effect on plasma total protein, total cholesterol, aspartate aminotransferase (AST),alanine aminotransferase (ALT) and creatinine, while, it is had significantly (p<0.01) decreasing total lipids as compared to the control. However, enzyme addition had not significant effects on all plasma constituents except oftotal lipids which significantly increased by enzyme addition only as compared to the control. In conclusion, the present results show that DDGS can be used successfully in growing rabbit feeding effectively and economically up to 28 % without adverse effect on growth peiformance.
