Selenium-enriched chicken feed containing edible fungus residues and production process thereof

Abstract

The invention provides a selenium-enriched chicken feed containing edible fungus residues. The feed is prepared from, by weight, 20-30 parts of needle mushroom fungus residues, 10-20 parts of zinc-rich edible fungus residues, 15-25 parts of corn, 15-25 parts of buckwheat, 15-25 parts of flaxseed meal, 15-25 parts of soybean meal, 5-15 parts of fish bone meal, 5-12 parts of lophatherum gracile, 5-12 parts of frangipani, 5-10 parts of conyza bonariensis, 10-20 parts of selenium-rich yeast powder, 0.1-0.2 part of composite strains, 0.2-0.5 part of a vitamin additive, 2-5 parts of zinc sulfate, 3-6 parts of zinc oxide, 5-15 parts of zinc gluconate, 5-10 parts of a feed additive and 20-40 parts of water. The invention also provides a production process of the selenium-enriched chicken feed containing the edible fungus residues. The process has low requirements for equipment and is scientific and reasonable, produced products are high in palatability and absorption rate, and the nutritionaldemands of chickens in different growth periods are met; not only is the selenium content of produced eggs moderate, but also the edible selenium supplementing effect is good, feed ingredients are fully utilized and absorbed, the waste of resources is reduced, and the economic benefits are increased.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a selenium-enriched chicken feed containing edible fungus residue and a production process thereof. Background technique [0002] Selenium is one of the essential trace elements for the human body. The low selenium status of the human body is closely related to the incidence of more than 40 diseases such as Keshan disease, cancer, cardiovascular disease, cataract, diabetes, and AIDS. Many animal experiments have also directly confirmed that selenium (especially bio-sourced organic selenium) has unique effects such as anti-cancer, anti-aging and anti-aging. Soil selenium deficiency is a widespread problem all over the world. In my country, 72% of the land is selenium deficient in varying degrees, forming a general low selenium state in the food chain. It is difficult to fundamentally improve the selenium deficiency situation only by supplementing selenium with natural foo...

Problems solved by technology

At present, most chicken feeds are added with sodium selenite to obtain selenium-enriched eggs, but sodium selenite is highly toxic, has a narrow safety range, and low bioavailability. Excessive or uneven consumption can easily lead to chicken poisoning, resulting in a drop in egg production rate. , or even die, too few and selenium-enriched eggs cannot be obtained, and chickens have a very low absorption rate of selenium in the existing selenium-enriched chicken feed. In addition, the existing selenium-enriched chicken feed is unstable and easy to absorb water and deteriorate

In addition, many chicken feeds and feeding processes do not distinguish chicken feeds according to the age of the chickens, and do not make corresponding adjustments in the feeding methods. It is just simple feeding. The survival rate of chickens is very low, and it is unhealthy and cannot produce good quality. selenium-enriched eggs, resources are not rationally utilized, and even cause waste of resources
