Abstract

ASBSTRACT          
This experiment was carried out to study the effect of using two levels from guar korma meal (25 or 50% from soybean meal in the diet), 4 or 8% in the diet with or without adding enzyme Hemicell®(β-mannanase enzyme) at a level (0.3kg/kg diet) on growth performance and carcass traits of growing rabbits. Sixty weaned New Zealand White (NZW) rabbits, six weeks old, with an average live body weight ranging from 772.2 to 785.6 g were randomly divided into five groups (twelve rabbits each). Each group was divided into three replicates, (four rabbits each).
The results indicate that there were insignificant (P>0.05) differences in average body weight and daily weight gain among rabbits groups fed control diet (without guar korma meal), 25% guar korma meal with adding β- mannanase enzymeand 50% guar korma meal with adding enzyme β-mannanase. Feeding rabbits on 25 or 50% guar meal without enzymeβ-mannanase significantly (P>0.05) decreased the average body weight and average daily gain, compared to those fed control diet. Rabbits group fed 50% guar korma meal with enzyme achieved the best feed conversion. Using guar meal at 50% level with adding enzymeβ-mannanase slightly improved digestibility coefficients of organic matter, crude fiber, ether extract and nitrogen free extract. Nutritive value was improved when rabbits fed diets containing 25 or 50% guar korma meal with enzyme compared to the other tested experimental groups. There were insignificant differences in empty carcass and dressing percentages when rabbits fed on 25 or 50% guar korma meal with or without enzyme compared to the control group. Moreover, growing rabbits feeding diets containing 25 or 50% guar korma meal with or without enzyme insignificantly decreased total volatile fatty acid and ammonia concentrationcompared to the controlgroup.Results given also indicated that groups fed 25 or 50% guar korma meal with enzyme were achieved the highest economic efficiency (5.55 and 6.82) and relative economic efficiency (119.35 and 146.6).
Conclusively, it is concluded that guar korma meal can be used in growing rabbit diets up to 8% in the diet (50% of soybean meal) with β-mannanase enzyme to reduce fed costs without adverse effects on performance of rabbits.
