Feed for producing storage-durable low-cholesterol selenium-rich green-shell eggs

Abstract

The invention belongs to the technical field of feed production, and provides a feed for producing storage-durable low-cholesterol selenium-rich green-shell eggs, wherein the feed is prepared from tea polyphenol with the purity of 98%, yeast selenium with the selenium content of 2000 mg / kg and basic feeding grains. The egg laying rate is improved obviously by tea polyphenol and yeast selenium, the material to egg ratio is lowered, and the average egg weight is increased; tea polyphenol can obviously delay the egg haugh unit to decrease in the storage process, the storage durability of eggs is improved, and according to the haugh unit value of a treatment group in the preserved test result at normal temperature (25 DEG C), the fresh egg freshness preservation period can be determined to be more than 15 days; 200 mg / kg-400mg / kg tea polyphenol is added in the basic feeding grains, the cholesterol content in egg yellow can be lowered obviously, and meanwhile, 0.25 mg / kg-0.50mg / kg yeast selenium is added in the basic feeding grains, the cholesterol content in egg yellow can be improved obviously; and in order to produce the low-cholesterol selenium-rich eggs and prolong the normal-temperature storage period of the eggs, the adding of tea polyphenol and yeast selenium with the combination effect of 400 mg / kg and 0.25 mg / kg is most suitable.

Description

technical field [0001] The invention belongs to the technical field of feed production, and in particular relates to a feed for producing storable, low-cholesterol, selenium-enriched green-shell eggs. Background technique [0002] In recent decades, animal nutrition has entered a deeper level of research, and the relationship between various nutrients has become one of the focal issues of nutrition research. [0003] The relationship between nutrients is synergy or antagonism, such as energy-protein, calcium-phosphorus, vitamin E and selenium, etc. The relationship between these elements has been clearly studied and widely used in production. However, what kind of application effect it has, such as what side effects it has while improving the growth of livestock and poultry, how it affects other nutrient utilization rates, and whether it has any effect on palatability, etc., still needs further discussion and research. [0004] Tea polyphenols is a general term for a class ...
