  • Beschreibung: <p>The feeding of captive exotic ducks is complicated by unintended use of the diet by other wild animals and birds that increases cost and may introduce disease. A submersible diet for ducks was tested for stability in water as well as its palatability to ducks and their successful adaptation to an underwater feeding regimen. Three binders, sodium alginate, high-gluten flour, and a processed whole-grain sorghum product (Nutri-Binder™), were tested for their ability to produce a stable pellet. Results showed that a submersible diet with Nutri-Binder at a 33% inclusion level remained stable in water longer than diets with the other binders. Water temperature affected the disintegration time of the pellet. The product lost its integrity more rapidly at higher water temperatures. When two groups of black ducks (Anas rubipes) were fed either the submersible diet or a conventional avian maintenance diet in crocks placed on the ground, both groups experienced overall weight gains. When the submersible diet was fed underwater, the ducks continued to respond positively and unintended use by other birds and mammals was reduced.</p>
