Selenium-rich feed for laying hens

Abstract

The invention discloses selenium-rich feed for laying hens. The selenium-rich feed comprises the following raw materials: 20-30 parts of a sawdust adsorbent, 10-20 parts of an activated carbon slow-release agent, 1-2 parts of 99% sodium selenite, 2-3 parts of 98% zinc sulfate, 70-80 parts of corn, 20-25 parts of wheat bran, 10-15 parts of bean meal, 10-15 parts of wheat, 10-15 parts of oat, 10-15parts of sesame cakes, 5-10 parts of fishmeal, 26-30 parts of stone powder, 1-3 parts of animal oil, 2-8 parts of calcium hydrogen phosphate, 13-15 parts of corn distiller's grains, 1-2 parts of choline chloride, 0.5-1 part of lysine, 0.4-0.8 part of methionine, 1-2 parts of threonine, 0.2-0.5 part of sodium chloride, 0.1-0.2 part of sodium humate, 0.1-0.2 part of M-P(T), 0.1-0.2 part of BV22A, 0.1-0.2 part of phytase and 0.3-0.5 part of complex enzymes. By research and application of the selenium-rich feed prepared using scientific and modern technologies, diseases caused by lack of seleniumtrace elements in poultry are treated, the survival rate is improved and healthy selenium-rich poultry meat is produced.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a feed for selenium-enriched laying hens. Background technique [0002] Selenium is an essential trace element for humans and animals. It is a component of glutathione peroxidase, which can eliminate free radicals in the body and protect the normal function of cell membranes. Studies in recent years have shown that selenium has the functions of anti-cancer, anti-cancer, heart protection, cataract prevention, cretinism and Kashin-Beck disease prevention, and anti-aging. [0003] At present, most feed production enterprises simply add sodium selenite or yeast selenium to feed to supplement selenium. Selenium plant feed material is a natural organic selenium-enriched material, its selenium content can reach 0.2-2.0mg / kg, all exist in the form of organic selenium, it is an excellent selenium-enriched feed material. [0004] Simultaneously existing selenium-enriched laying ...

AI Technical Summary

Problems solved by technology

[0003]At present, most feed manufacturers simply add sodium selenite or yeast selenium to feed to supplement selenium, which is a kind of inorganic selenium. Due to its low absorption and utilization rate, The effect of edible selenium supplementation cannot be achieved. The selenium-enriched plant feed material grown in the selenium-enriched area is a natural organic selenium-enriched raw material, and its selenium content can reach 0.2-2.0mg / kg, all of which exist in the form of organic selenium. It is an excellent selenium-enriched feed material

[0004] At the same time, existing selenium-enriched laying hen feed mixing devices generally have defects such as incomplete pulverization and poor mixing effect, thus causing poor quality of selenium-enriching laying hen feed
