Problems solved by technology

With the scale and intensification of the poultry industry, free-range farming cannot be widely used, and the content of β-carotene in commonly used seed feeds, such as wheat, soybeans and corn, is low, resulting in β-carotene in eggs produced by cage chickens. Carotene content is generally low

Embodiment 1

[0025] The functional feed additive and functional complete feed that can be used to produce β-carotene enriched eggs are prepared by the following preferred method:

[0026] (1) Red pepper and Dunaliella salina dried to a water content of 4% are processed with a small-scale high-speed pulverizer, so that the particle size of the two plants reaches 60 mesh, and red pepper meal and Dunaliella salina meal are obtained.

[0027] (2) Mix 1kg of red pepper meal with 4kg of Dunaliella salina meal, and then add additive—0.6kg of feed grade Na 2 CO 3 Solid, mix well.

[0028] (3) Add the mixed red pepper / Dunaliella salina / auxiliary mixture into a vibrating grinder, grind for about 30 minutes, and finally make the particle size of the red pepper / Dunaliella salina micro-cut auxiliary powder reach about 400 mesh, and obtain Feed additive for the production of beta-carotene enriched eggs.

[0029] (4) Add the prepared feed additive to the poultry basal diet at a ratio of 0.5 to 3.5%, t...

Embodiment 2

[0031] Add 3.5% of the feed additive provided by the invention into the basal ration, mix well and evenly, and obtain the powder feed for laying hens rich in beta-carotene and various nutritional components in capsicum and dunali algae.

[0032] The test results showed that: compared with the control group, the average egg weight of the test group increased by 7.38%, the egg production rate increased by 8.79%, and the feed-to-egg ratio decreased by 6.53%. β-carotene in eggs increased by 209.03% on the 7th day of feeding, 524.6% on the 14th day of feeding, and was still 19.12% higher than that of the control group after 8 days of stopping feeding, with an average increase of 236.23%.

Embodiment 3

[0034] Add 1.0% of the feed additive provided by the invention into the basic ration, mix well and evenly, and obtain the powdery feed for laying hens rich in beta-carotene and various nutritional components in capsicum and dunali algae.

[0035] The test results showed that: compared with the control group, the average egg weight of the test group increased by 7.71%, the egg production rate increased by 4.81%, and the feed-to-egg ratio decreased by 7.87%. β-carotene in eggs increased by 159.35% after 7 days of feeding, 237.86% after 14 days of feeding, and 53.62% after 8 days of non-feeding, with an average increase of 159.72%.

Abstract

The invention discloses a feed additive for the production of Beta-carotene-rich eggs and a preparation method thereof, which belong to the technical field of feeds. The novel feed additive is characterized in that: the feed additive contains microshear-additive red pepper powder and microshear-additive dunaliella powder which are obtained by the processing of the microshear-additive interaction technique, wherein the mixture ratio of the microshear-additive red pepper powder to the microshear-additive dunaliella powder is between 1:2 and 1:6. The invention utilizes the advanced microshear-additive interaction technique to process natural plants, so that a great deal of Beta-carotene in the natural plants can be released and easily absorbed by animals, consequently, compared with the conventional processing technique, the invention notably reduces the amount of added red peppers and dunaliella, so that the production cost is saved, moreover, the potential hazard of ingredients (such as capsaicin) irritating the intestinal tracts of female poultry is reduced, and ultimately, the content of Beta-carotene in eggs and the weights of eggs can be notably increased; moreover, the processis simple, and the feed additive is convenient to use.

Description

technical field [0001] The invention belongs to the technical field of feed, and relates to a production technology for producing β-carotene bio-enriched eggs by using a micro-cutting aided interaction technology and a product thereof. Background technique [0002] As the precursor of vitamin A, β-carotene can be used by the human body to synthesize vitamin A and prevent and treat various vitamin A deficiencies. In addition, β-carotene has the effects of anti-cancer, anti-oxidation, prevention of cardiovascular diseases, and improvement of the body's immunity. Nutrition surveys show that the intake of β-carotene and vitamin A in the Chinese diet is insufficient, and there is a big gap between the recommended intake and it is easy to cause dry eyes, corneal sclerosis, respiratory infections, skin ulcers, skin cancer, etc. , is one of the main reasons for the sub-health of the population. At present, the main method of supplementing β-carotene is to rely on drugs and cod liv...
