Forage capable of promoting duck to produce red-yolk duck eggs

Abstract

The invention discloses forage capable of promoting a duck to produce red-yolk duck eggs. The forage is prepared by using corn flour, yellow soybean meal, wheat bran, fish meal, seaweed powder, shell powder and shrimp shell powder. Seafood accounts for a large proportion in raw materials of the forage; a food structure of beach ducks is simulated; enough nutrition ingredients are provided for the ducks; the red-yolk sea duck eggs can be produced by the ducks raised by the forage. The forage has comprehensive nutrition, high protein content, reasonable proportions, simple preparation process and easy implement. Contrast experiments for feeding the ducks with the forage provided by the invention and a commercially available duck forage show that the forage has scientific and reasonable formula, and can promote the ducks to produce the red-yolk duck eggs having similar components with the sea duck eggs.
