Abstract
Forty-five New Zealand White weaned male rabbits of five weeks of age with nearly equal live body weights were randomly allotted to five groups with three replicates of 3 rabbits each. Five pelleted experimental diets were formulated to be approximately Iso-nitrogenous. Treatment diets were formulated by replacing 50 or 100% of yellow corn in the control one by ground date stone with or without Kemzyme (at a level of 0.5 kg/ton of rabbit feed). The results indicated that 50% replacement of yellow corn ground date stone (with or without Kemzyme) significantly (P<0.05) improved feed conversion efficiency of growing male rabbits during the experimental
period. Replacing of yellow corn at e . or \ .. % by ground date stone with Kemzyme supplementation slightly improved digestibility coefficients of dry matter, crude protein, crude fiber, ether extract and NFE. Besides supplementation to the replaced> . % ground date stone with Kemzyme improved digestibility coefficients ADF, NDF and TDN. Dressing percentage was significantly (P<0.05) higher with supplementing
Kemzyme to e . or \ .. % ground date stone, compared to the other experimental groups. The obtained results indicated that ground date stone could be used on the site of yellow corn (50% substitution) either without or specially Kemzyme supplementation which showed best performance and economic efficiency.
In general, the results indicated that ground date stone could replace yellow corn in rabbits feed by 50% either with or without Kemzyme, to realize the best production and economic efficiency values.
