The invention belongs to the field of animal feeds, and particularly discloses a
feed additive capable of improving
yolk color and egg quality. The
feed additive capable of improving the
yolk color and the egg quality is prepared from the following
active components in parts by weight: 50-150 parts of
thallus laminariae
powder, 0.002-0.006 part of lactoflavin, 50-150 parts of chili
meal, 0.0005-0.005 part of
xanthophyll, 50-150 parts of southernwood
powder, 50-150 parts of dried marine
algae powder and 50-150 parts of orange peel powder. The
feed additive capable of improving the
yolk color and the egg quality is reasonable in formula, and simple to prepare, can notably increase the
egg laying rate of egg
layers, and can prolong the peak period of
egg laying. After laying hens eat the feed additive, the yolk color can be obviously improved, the egg weight is increased, a
cholesterol content in yolk is reduced, the
immunity of the laying hens is improved, the color of eggshells is deepened, the egg destruction rate is reduced, and the material egg ratio is reduced; after the laying hens eat the feed additive, the situation that
toxin is remained in the bodies and eggs is avoided, the commodity value of the eggs is increased, and the market competitiveness is improved; besides, the feed additive improves the
economic benefits for breeding households.
