Abstract
- Four hundred and fifty of 7 days old Muscovy ducklings were distributed into fifteen groups; the experimental treatments were arranged in a one way design by using 4 diets contained 0, 10, 20 or 40% of barely grains; or the same four barley groups supplemented with 1g/kg from commercial enzyme; or the same four barley groups were pelted; 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 thatincreasing barley grains levels in duckling diets decrease in feed intake with increase in feed conversion; decrease in carcass % . Adding enzyme or pelleting the experimental diets reduced NSP resulting and duodenum viscosity; improved digestibility coefficients and nutritive values. Pelting barley grains diets recorded highest significant live body weight and body gain compared with pelted control diet; improved feed conversion; improved carcass %. Sprouting technique had recorded the highest desirable results which reflect highest improvement in digestibility coefficients and nutritive values; highest improvement in live body weight , body gain and feed conversion to the extent 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 economic efficiency and relative economic efficiency were for group fed sprouted barley 20% or 40% being 105%
