A total of fifty weanling New Zealand White (NZW) rabbits that were five weeks old (800 g live weight on average) were randomly allocated into five groups of 10 rabbits each and were housed in individual cages. The groups were control (12% CF and 30.08 NDF), 14% CF without enzymes (30.69 NDF), 14% CF with enzymes (30.69 NDF), 16% CF without enzymes (31.76 NDF), 16% CF with enzymes (31.76 NDF) for groups 1, 2, 3, 4, and 5, respectively. All groups received pelleted diets ad libitum for 6 weeks. Daily feed intake was recorded and total feces were collected daily and weighed individually during four days for digestibility trial. live body weight (BW), daily weight gain (WG), feed intake, feed conversion ratio (FCR) were evaluated. Apparent digestibility of nutrients [crude protein (CP), Dry matter (DM), ash], carcass traits, and some blood serum constituents (glucose, total protein, albumin, AST, and ALT) were determined. Also, the economic efficacy of this study was determined. The results showed significant reduction (P
