Abstract
This study aimed to evaluate the effect of inclusion of guar korma meal (GKM) as a partial replacement for soybean meal (SBM) in commercial local strain (Anshas) diets on growth performance, digestibility, slaughter traits and economical efficiency. The experimental period lasted for 3 months. Chicks received (GKM) at 0, 2.5, 5, 7.5 and 10% with or without β-mannase enzyme (Hemicell®) supplement. Results indicated that GKM without enzyme can be used as a feed ingredient without adverse effect at level 2.5%. Using GKM in levels more than 2.5% depress weight gain, feed conversion and nutrients digestibility. Addition of enzyme to the diets improve weight gain, feed conversion and nutrients digestibility of diets containing 5% of GKM. Feed intake increased as the level of GKM in diets increased. Enzyme supplement had no effect on feed intake. Enzyme supplement could not overcome the adverse effect of GKM on nutrients digestibility only in diets contain 7.5 and 10% of GKM. Dressing percentage decreased as the level of GKM in diet increased. Addition of enzyme to the diets contain GKM improved dressing percentage. GKM can be used without enzyme addition at level 2.5% without adverse effect on dressing percentage.
From the nutritional and economical points of view, results indicated that GKM can be used as a feed ingredient at level 2.5% without enzyme supplement. When enzyme was added to the diets level of GKM can be increased up to 5% without any adverse effect.
