10. Comparative Study of the Energy Nutritive Values of Some New Maize Hybrids in Experiments with Muscovy Ducks (Cairina Moshata L.)

Using adapted methods for balance experiments with Muscovy ducks, the apparent (AMEn-o) and the true (TMEn-o) metabolizable energy of 4 grain-maize hybrids – PR35P12, PR37D25, Clarica and PR35Y540 have been established. The PR35P12 hybrid shows the highest AMEn-o – 16.44, and PR35Y540 (15.89 MJ/kg DM) – the lowest. The PR35P12 hybrid shows the highest TMEn-o for Muscovy ducks – 17.40, and PR35Y540 (17.05 MJ/kg DM) – the lowest.
