AB  - A ten-weeks feeding trial was conducted to assess the effect of inclusion of Maize Milling Waste (MMW)  with/without xylanase supplementation on the performance characteristics, nutrient digestibility, haematological traits and carcass characteristics of weaner rabbits. A total of 48 unsexed, crossbred weaner rabbits were randomly allotted to the experimental diet in a 2 x 4 factorial arrangement with MMW at graded levels (0, 12, 23 and 35%) and two xylanase levels (0 ppm, 100 ppm). There were eight treatment groups of six rabbits each per treatment group(3 replicate of 2 rabbits per replicate). The final live weight of the rabbit were significantly (p&lt;0.05) affected by MMW inclusion levels and it decreases as inclusion level of MMW increases from T<SUB>1</SUB> to T<SUB>4</SUB> and T<SUB>3</SUB> to T<SUB>8</SUB> respectively. Xylanase inclusion has no effect and hence did not improve the feed intake, final weight or weight gain. Nitrogen retention and crude fibre digestibility were not significantly (p&lt;0.05) affected by the treatment. Ash digestibility significantly (p&lt;0.05) increases as the inclusion level increases. Carcass yield indicated that shrunk weight, empty carcass weight and head were significantly (p&lt;0.05) affected by the treatment imposed. The empty carcass weight reduces with increase in MMW inclusion level from 1165.30 g to as low as 999.30 g T<SUB>4</SUB>. The same trend also applies for the xylanase supplemented diets. The haemoglobin, red blood cell, mean corpuscular volume and white blood cell were all significantly (p&lt;0.05) affected by the treatment. The result indicated that above 12% MMW inclusion level may have adverse effect (with/without xylanase enzyme supplementation) on rabbit performance and nutrient utilization and may not be a promising energy supplement beyond inclusion level of 12% in a weaner’s diet.
