Feed for producing selenium-rich storage-resistance green-shell eggs and enhancing chicken body antioxidation capability

Abstract

The invention belongs to the technical field of feed production and provides a feed for producing selenium-rich storage-resistance green-shell eggs and enhancing the chicken body antioxidation capability. The feed consists of basic ration and yeast selenium with the selenium content being 2000 mg / kg, wherein 0.25 to 0.50mg / kg of selenium is added into the basic ration in a yeast selenium form in the basic ration, the Haugh unit reduction in the storage process of egg products can be obviously delayed, in addition, the fresh keeping time of the fresh eggs below the normal temperature of 25 DEG C can be prolonged by more than 15 days; 0.25 to 0.50mg / kg of selenium is added into the basic ration in a yeast selenium form, so the yolk selenium content is improved by 49.15 to 110 percent, the content of 0.437mug / g to 0.637mug / g can be reached, and the chicken body antioxidation index is obviously enhanced; the influence of the selenium on the green-shell hen production performance, the egg quality, the yolk selenium content and the blood serum antioxidation capability is analyzed, the addition of the selenium in the basic ration of the hen is optimized, and the scientific basis is provided for the application of the selenium to the egg poultry culture and the production and the development of the selenium-rich eggs.

Description

technical field [0001] The invention belongs to the technical field of feed production, and in particular relates to a feed for producing selenium-enriched and storage-resistant green-shell eggs and enhancing the antioxidant capacity of chicken bodies. Background technique [0002] Selenium is an essential trace element for humans and animals. It is closely related to regulating growth, improving immunity, anti-cancer, anti-oxidation, anti-stress, delaying aging and preventing endemic diseases. The intake of selenium for humans and animals It is generally low, and the ability to store selenium in the human body is very weak. It is necessary to eat foods with high selenium content to obtain enough selenium. Therefore, it is of great significance to develop foods rich in selenium. [0003] Selenium-enriched yeast is a biological selenium preparation with high selenium content transformed by microorganisms. Compared with inorganic selenium, selenium has high activity and low to...
