Feed additive for ducks producing selenium-rich rhizoma curcumae longae duck eggs

Abstract

The invention relates to a feed additive for ducks producing selenium-rich rhizoma curcumae longae duck eggs. The feed additive is prepared from the following components: 8-16 parts of astragalus polysaccharide, 12.2-24 parts of chitosan, 8.6-17 parts of curcumin, 5-10 parts of allicin, 0.2-0.3 part of chromium nicotinate, 10-31.4 parts of selenium yeast, 0.8-34 parts of fructus crataegi and 0.5-22 parts of cassia seed. The feed additive, which accounts for 0.2-0.3 percent by weight of a basic ration, is added into the basic ration of the laying ducks, and the eggs laid by the laying ducks fed with the basic ration for 28 days contain yolk immunoglobulin, lecithin, selenium and rhizoma curcumae longae of high content, and cholesterin of low content, have wide health care functions, and play an important role in the aspects of benefiting the intelligence, preventing the alzheimer disease and the disease of cardiovascular system, resisting cancers and ageing, improving the immunity of a human body, and the like.

Description

technical field [0001] The invention relates to the technical field of poultry feed, in particular to the technical field of using green pollution-free feed additives to produce health-care functional eggs, and in particular to a duck feed additive for producing selenium-enriched turmeric duck eggs. Background technique [0002] In recent years, great changes have taken place in the dietary structure of urban and rural residents in my country, and cardiovascular disease has become the number one killer threatening national health. At the same time, with the increasing number of elderly people in my country, the prevalence of Alzheimer's disease has also increased. Both have brought enormous pressure and burden to the society and family, therefore, it is urgent to effectively prevent cardiovascular disease and senile dementia through food intervention. [0003] Selenium is an essential micronutrient element for the human body. The 35°-60° north latitude in the world is basical...

Problems solved by technology

Although existing patents disclose production methods of selenium-enriched duck eggs or selenium-enriched and low-cholesterol duck eggs, these technologies only increase the selenium content in duck eggs and reduce the cholesterol concentration in duck eggs, but do not affect the content of other functional substances that have health effects in eggs. No effect, and does not contain curcumin, which has anti-cancer effects
