Problems solved by technology

[0005] There are 9 patents applied for by the predecessors to develop selenium-enriched eggs. After reviewing the previous patents, it can be found that the development of selenium-enriched eggs has roughly gone through four stages: the earliest use of inorganic selenium, but adding high doses of sodium selenite has harmful effects on laying hens. Toxicity, which affects egg production rate; later, selenium-rich crops were used as feed materials to produce selenium-rich laying hen feed, relying on selenium-rich crops, which required special cultivation, and the development of selenium-rich eggs was complicated; began to use additive products, such as nano-selenium and seaweed selenium Polysaccharides, but because the product is not listed in the feed additive catalogue, there are legal issues

Embodiment 1

[0042] Prepare the basal ration: the content of corn in the basal ration is 54.00wt%, the content of soybean meal is 17.00wt%, the content of wheat is 12.00wt%, the content of the basal ration premix is ​​2.00wt%, and the content of stone powder is 10.00wt%, the content of pine needles is 5.00wt%. The basic diet premix provides 500000IU of VA, 240000IU of VD3, 500IU of VE, 180mg of VB2, 150mg of VB6, 450mg of copper, 5200mg of iron, 4000mg of manganese and 2800mg of zinc per kilogram of feed.

[0043] Yeast selenium premix preparation: 500g yeast selenium (selenium content is 2000mg / kg) and 2500g carrier (secondary powder) are fully mixed to obtain yeast selenium premix. The prepared yeast-selenium premix was added to the basal diet of laying hens to obtain selenium-enriched feed 1#, and the selenium content in the selenium-enriched feed reached 1.0 mg / kg.

The basic diet premix provides 500000IU of VA, 240000IU of VD3, 500IU of VE, 180mg of VB2, 150mg of VB6, 450mg of copper, 5200mg of iron, 4000mg of manganese and 2800mg of zinc per kilogram of feed.

[0046] Yeast selenium premix preparation: 550g yeast selenium (selenium content is 2000mg / kg) and 2450g carrier (secondary powder) are fully mixed to obtain yeast selenium premix. The prepared yeast-selenium premix was added to the basal diet of laying hens to obtain selenium-enriched feed 2#, and the selenium content in the selenium-enriched feed reached 1.1 mg / kg.

Embodiment 3

[0048] Prepare the basal ration: the content of corn in the basal ration is 54.00wt%, the content of soybean meal is 17.00wt%, the content of wheat is 12.00wt%, the content of the basal ration premix is ​​2.00wt%, and the content of stone powder is 10.00wt%, the content of pine needles is 5.00wt%. The basic diet premix provides 500000IU of VA, 240000IU of VD3, 500IU of VE, 180mg of VB2, 150mg of VB6, 450mg of copper, 5200mg of iron, 4000mg of manganese and 2800mg of zinc per kilogram of feed.

[0049] Yeast selenium premix preparation: 750g yeast selenium (selenium content is 2000mg / kg) and 2250g carrier (secondary powder) are fully mixed to obtain yeast selenium premix. The prepared yeast-selenium premix was added to the basal diet of laying hens to obtain selenium-enriched feed 3#, and the selenium content in the selenium-enriched feed reached 1.5 mg / kg.

Abstract

The present invention provides a feed composition, a preparation method and an application thereof, and a method for producing selenium-enriched eggs. The feed composition comprises yeast selenium anda basic feed diet, wherein a selenium content of the feed composition is 1.0 mg/kg-1.5 mg/kg. A selenium content of the yeast selenium is 1,500-2,500 mg/kg and preferably 2,000 mg/kg. When an egg production rate of poultries (egg laying chickens) is larger than 90%, the feed composition is used for the poultries (egg laying chickens). The poultries (egg laying chickens) produce the selenium-enriched eggs after 5 days. In the selenium-enriched eggs, a selenium content in egg white reaches 0.68-1.11 mg/kg, a selenium content in egg yolk reaches 0.9-1.8 mg/kg, and a selenium content in whole eggs reaches 0.8-1.3 mg/kg.

Description

technical field [0001] The invention belongs to the field of animal husbandry, relates to the technical field of using organic trace elements to produce poultry eggs, in particular to a feed composition for producing selenium-enriched eggs (such as eggs), a preparation method, application and a method for producing selenium-enriched eggs. Background technique [0002] Yeast selenium is an organic selenium source developed by yeast. It is produced by selenium enrichment in the cell protein structure of growing yeast. Yeast selenium has been proved to be safer, more stable and easier to absorb than inorganic selenium, and has many aspects. Health care function, after satisfying the animal's physiological demand for selenium, it can also be stored in the animal's body to avoid selenium deficiency again in a short period of time. [0003] The distribution of selenium in the natural environment is uneven. In my country, from the three northeastern provinces to the Yunnan-Guizhou ...
