Production method of selenium-rich chicken eggs

Abstract

The invention discloses a production method of selenium-rich chicken eggs and aims to overcome the defects of the prior art. The production method includes the steps of 1, mixing well nano-selenium and conventional basic ration for layers into nano-selenium feed; 2, feeding the layers with the nano-selenium feed twice a day, and allowing the layers to feed freely until selenium content of the chicken eggs is stably between 0.4mg/kg and 1.52mg/kg after 10 days; 3, continuing to feed the layers with the nano-selenium feed until the selenium-rich chicken eggs with the selenium content stably ranging from 0.4mg/kg to 1.52mg/kg are obtained after 14 days. Preferably, the selenium content of the nano-selenium feed is 0.5-2.0mg/kg, the particle size of effective ingredient selenium in the nano-selenium ranges from 10 nanometers to 500 nanometers. The production method has the advantages that the nano-selenium for use is an industrial product which is pink or red powder, the added nano-selenium features stable quality, high efficiency, low toxicity, low price and the like, the process of the production method is simple, the production method is economical in cost and high in safety, the selenium-rich chicken eggs produced by the production method are stable in quality and high in selenium content.

Description

technical field [0001] The invention relates to a method for producing selenium-enriched eggs, in particular to a method for producing selenium-enriched eggs that is safe, low-cost and simple in process. Background technique [0002] Selenium is one of the indispensable trace elements for human and animal organisms. Selenium participates in human metabolism and is a component of glutathione peroxidase, which can prevent peroxidase from accumulating in cells, thereby protecting cells from damage. Selenium deficiency can cause a series of diseases in humans and animals. Reasonable supplementation of selenium can enhance people's physical fitness, enhance the body's immunity, and prevent and treat diseases. According to a large number of data, selenium can prevent and treat Keshan disease and Kaschin-Beck disease, and has certain curative effects on hypertension and cardiovascular diseases; Enhance immunity and anti-aging effect; have antagonistic effect on heavy metal poison...

And a kind of organic selenium (amino acid chelated selenium) that Chinese invention patent application CN92109302.0 provides is mixed in poultry feed, is used to produce selenium-enriched eggs, although this method is safe, but this organic selenium of amino acid chelated selenium, production process Complex, expensive, difficult to promote in production

In addition, the Chinese invention application patent 201110240687.2 describes that selenium-rich alfalfa is made into grass powder, and then the grass powder is evenly mixed in a certain proportion (percentage by weight) to produce selenium-rich eggs in the conventional feed of laying hens. Although this method is simple Effective, but because selenium-enriched alfalfa does not exist in selenium-deficient areas, it has no general promotion significance and is not suitable for large-scale standardized promotion and application
