| Abstract | ||
| Four hundred and fifty Muscovy ducklings (7 days) were distributed into fifteen groups; 4 basal diets contained 0, 10, 20 or 40% of barely grains; or supplemented with 1g commercial enzyme /kg diet; or 4 pelted barely diets; finally, three sprouted percent of barley grains 10, 20 and 40% were used in three experimental diets comparing with the basal control diet. Results showed that increasing barley grains levels in duckling diets reflect significant increase in the non -starch polysaccharides (NSP) and duodenum viscosity ;gradual decrease in digestibility coefficient and nutritive values; ducklings fed diet contained 40% barley grain had lower significant gain compared with control; gradual decrease in feed intake with increase in feed conversion; decrease in carcass % . Adding enzyme or pelleting the experimental diets improved digestibility coefficients and nutritive values. Sprouting technique had recorded the highest desirable results which reflect that group fed 40% barley grains had the best feed conversion compared with other treatments and lowest weights was recorded by group fed basal diet; the highest relative economic efficiency were for groups fed sprouted barley 20% or 40% being 105%. | ||
