| The current study was carried out to study the effect of using different levels of guar korma meal (GKM) with β-mannanase and protease enzymes in the diet of Inshas chicks on growth performance traits, nutrients digestibility and economic efficiency. Experimental diets were formulated to included 0.0, 2.5, 5.0, 7.5 and 10.0% guar korma meal. The experiment started with one day old Inshas chicks and lasted for 12 weeks. Two hundred and twenty five Inshas chicks were randomly divided into five groups (45 birds for treatment). Each treatment consisted of 3 replicate (15 birds/ replicate). Results indicate that inclusion of (GKM) in chicks diet up to 7.5% supplemented with enzymes lead to insignificant (P>0.05) increase in final body weight and weight gain. While, inclusion at rate 10% lead to significant decrease in final body weight and weight gain (P<0.05) as compared to control treatment. Using guar korma meal up to 7.5% level slightly improved digestibility coefficients of organic matter, crude fiber, ether extract, nitrogen free extract, and nutritive value when compared to control with no significant difference (P>0.05). While, using (GKM) in feed at 10% lead to significant decrease in nutrient digestibility (P<0.05). Similarly, there were insignificant differences in empty carcass and dressing percentages when chicks fed with diet contain up to 7.5% (GKM) compared to the control group. While, the inclusion of (GKM) at rate 10% in diet significantly decrease (P<0.05) carcass and dressing compared to control. Also, the results indicate that use of (GKM) in diet reduced feed cost per chicks. However, the highest net revenue, economic efficiency and relative economic efficiency were obtained at inclusion rate 7.5% of guar meal in chick diet. Conclusively, it could be concluded from the present study that Guar Korma Meal can be used in growing Inshas chicks diets up to 7.5% in the diet with β-mannanase and protease enzymes to reduce fed costs without adverse effects on performance of chicks. | ||
