A kind of laying hen feed additive and preparation method thereof

Abstract

The invention discloses a feed additive for laying hens at an egg producing period and a preparation method of the feed additive. The feed additive comprises traditional Chinese medicine additives, an enzyme composition and vitamin D3, wherein the weight part ratio of the traditional Chinese medicine additives to the enzyme composition to the vitamin D3 is 1 to 1 to (0.01-0.5); the traditional Chinese medicine additives comprise following raw material medicines: seaweeds, rhizoma atractylodis, codonopsis pilosula, pseudostellaria heterophylla, chrysanthemums, symphytum officinale, pollen, salvinia natans, endothelium corneum gigeriae galli, poncirus trifoliata, fructus amomi, Chinese yams, hyacinth beans, jujubes, curculigo orchioides, medlar, walnut kernels, semen cuscutae, glutinous rice root hairs and maidenhairs. The feed additive has the beneficial effects of containing the traditional Chinese medicine additives and having the effects of tonifying spleen, eliminating dampness, tonifying kidney and spleen; compared with those in other raw materials, the content of cholesterol of eggs of the laying hens can be reduced, and the laying rate and the egg weight are increased; the disease resisting capability of the laying hens can also be improved.

Description

technical field [0001] The invention relates to an animal breeding feed additive containing raw materials derived from plants, animals or minerals, in particular to a feed additive for laying hens during egg production and a preparation method thereof. Background technique [0002] Eggs were rated as "the most nutritious breakfast in the world" by an American magazine. According to the magazine, eggs not only contain a variety of well-known nutrients, but also contain two amino acids, tryptophan and tyrosine, which can help the body resist oxidation. [0003] Eggs are one of the best sources of nutrition for humans. Eggs contain a lot of vitamins and minerals and proteins with high biological value. For humans, eggs have the best protein quality, second only to breast milk. The calories contained in an egg are equivalent to the calories of half an apple or half a cup of milk, but it also contains 8% phosphorus, 4% zinc, 4% iron, 12.6% protein, and 6% vitamin D , 3% vitami...
