Abstract

The invention relates to the technical field of feed additives, and provides a feed additive which is composed of an organic trace element group, a medicinal and edible plant group, a functional nutrition group and a compound vitamin group according to specific parts by weight, wherein the organic trace element group comprises 550-650 g of organic selenium, 250-350 g of zinc methionine and 150-250 g of glycine iron; the medicinal and edible plant group comprises 35-45 kg of astragalus membranaceus powder, 25-35 kg of Chinese wolfberry fruit powder and 20-30 kg of Chinese yam powder; and the functional nutrition group comprises 45-65kg of spirulina powder of 100-200 meshes and 1.0-1.5 kg of soybean lecithin with the phosphatidylcholine content of more than or equal to 20%. Medicinal and edible plants and organic trace elements are combined, risk raw materials such as inorganic selenium are abandoned, and scientific synergistic matching is combined, so that the selenium content and the calcium content of egg products are stably increased, heavy metal and antibiotic residues are not detected, the cholesterol content is remarkably reduced, and the egg products completely meet the food safety standard; the core problems that a traditional additive is insufficient in safety and unstable in nutrition enrichment are solved.
