Description

Laying hen compound feed additive for producing low-residue high-nutrition red date eggs and preparation method thereof Technical Field The invention relates to the technical field of feed additives, in particular to a laying hen compound feed additive for producing low-residue high-nutrition red date eggs and a preparation method thereof. Background With the increase of the demands of consumers on functional foods, low-residue and high-nutrition special eggs (such as selenium-enriched eggs and high-calcium eggs) become market hot spots. The quality core of the red jujube eggs used as functional eggs with nutrition and flavor depends on the scientific proportion of the laying hen feed. The feed additive is used as a key carrier for nutrition enrichment of eggs, and simultaneously meets the requirements of nutrition fortification, safety, no residue and adaptation to the physiological characteristics of laying hens, and is a core technical support for realizing large-scale and standardized production of red date eggs. At present, the feed additive for functional egg production is mainly divided into two types, namely a single nutrition supplementing additive, which is used for enriching specific nutrition elements by adding inorganic selenium, calcium carbonate and other raw materials, and a simple composite additive, which is used for mixing trace elements, vitamins and plant extracts and lacks a definite synergistic ratio design. In the prior art, a direct mixing process is mostly adopted, parameters such as raw material pretreatment, mixing rotating speed and time are not accurately controlled, and the nutrition index of eggs is tried to be improved mainly by adjusting the additive adding proportion. The existing feed additive for producing functional eggs has the obvious defects that a single nutrition supplementing additive depends on inorganic selenium, calcium carbonate and other raw materials, has low bioavailability and is easy to cause heavy metal residue risk of the eggs, a simple composite additive is simply overlapped by components, lacks scientific synergistic ratio design and cannot fully exert the functions of the components, the preparation process is extensive, key parameters such as raw material pretreatment, mixing rotating speed and time and the like are not accurately controlled, the mixing uniformity of products is poor, the fluctuation of batch quality is large, the nutrition index of the eggs is difficult to reach the standard stably, and meanwhile, part of the additive is complex in application operation and poor in suitability and popularization. Disclosure of Invention The invention aims to solve the technical problems of low enrichment efficiency and safety of nutrient elements, lack of multicomponent synergistic mechanism and the like of the laying hen feed additive in the prior art, and provides a laying hen composite feed additive for producing low-residue high-nutrition red date eggs and a preparation method thereof. The invention aims at realizing the purposes by adopting the following technical scheme that the laying hen compound feed additive for producing low-residue high-nutrition red date eggs comprises an organic trace element group, a medicinal and edible plant group, a functional nutrition group and a compound vitamin group which are combined according to specific parts by weight: Organic trace element group of 550-650 g organic selenium, 250-350 g zinc methionine and 150-250 g iron glycine; The medicinal and edible plant group comprises 35-45 kg of astragalus powder, 25-35 kg of medlar powder and 20-30 kg of yam powder; 45-65 kg of 100-200 mesh spirulina powder and 1.0-1.5 kg of soybean lecithin with phosphatidylcholine content more than or equal to 20%; the vitamin complex comprises 80-120g of vitamin A, 3 -100g of vitamin D and 100-150g of vitamin E. Preferably, the organic selenium is yeast selenium, and the selenium content is 2000-3000 mg/kg calculated by elements. Preferably, the spirulina powder is prepared by naturally cultured spirulina platensis through low-temperature drying, and the protein content is more than or equal to 60% and the water content is less than or equal to 8%.
