The invention relates to a
feed additive for optimizing nutritional ingredients of poultry eggs. The
feed additive comprises natural grains, soybean flavone,
lotus leaves, microalgae and a microalgae extract. The
feed additive comprises the following raw materials in percentage by weight: 20-70% of corn, 5-10% of wheat
bran, 5-10% of
soybean meal, 2-5% of soybean isoflavone, 5-10% of
lotus leaf
powder, 10-20% of spirulina
powder, 5-10% of
chlorella powder and 5-20% of
haematococcus pluvialis. The preparation method comprises the following steps: fully stirring and uniformly mixing the components, sub-packaging, adding into laying
fowl feed according to the proportion of 1-2wt%, fully and uniformly mixing, feeding laying hens, and domesticating and feeding for 2-3 weeks to obtain eggs rich in nutritional ingredients such as proteins,
flavonoid compounds,
algae source carotenoids, vitamins,
inorganic salts and the like. Compared with common eggs, the egg
yolk cholesterol content can be reduced by more than 1 / 4; the
egg white and the
yolk are clear in boundary, the
yolk is orange red, the fishy smell is obviously smaller than that of common eggs, and the yolk tastes fine and smooth; the obtained feed additive has a remarkable optimization effect on nutritional ingredients of poultry eggs, meanwhile, the taste and quality are improved, and
economic benefits are increased.
