Problems solved by technology

[0005] Defects: (1) The main active ingredient in eggs is the egg yolk antibody in the egg yolk, while the egg white can be separated as a high value-added food ingredient and sold separately after spray drying. The market price of the product is about double
[0006] (2) This method needs to be processed for 36 hours in a constant temperature drying oven at 55°C, which is too long
[0009] Defects: (1) Although the egg yolk liquid will be dehydrated and dried within a few seconds, the spray drying temperature is relatively high, and the egg yolk antibody activity in the egg yolk powder obtained by drying at this temperature will be lost
The retention time in the drying tower is 2-3 hours, and the temperature in the general drying tower will reach above 60°C, so long-term baking will also affect the activity of egg yolk antibody
[0010] (2) This preparation method produces egg yolk powder, but in the animal husbandry industry, a considerable part of the feed is generally fed in the form of pellets, such as some piglet creep feed, aquatic feed, pet feed, etc., if If the prepared egg yolk powder is re-prepared into granules, it needs to be re-added with water to granulate and then dry again, which is time-consuming and labor-intensive

Embodiment 1

[0043] The preparation of embodiment 1 immune egg

[0044] 1) Prepare mixed antigen:

[0045] Five species of Escherichia coli (K88\K99\987P\F18\F41) that cause diarrhea in piglets were cultured on a large scale under appropriate medium (TSA, Slanetz and Minca agar medium) and culture conditions, and the bacterial liquid was collected and used The pilus and the thallus are broken and separated by the shaking method in a water bath, and the pilus liquid without the bacterium is obtained after two times of centrifugation. The pili liquid was mixed according to the concentration ratio of 1:1:1:1:1 to obtain the mixed antigen, the final concentration of the mixed antigen was 50-500 mg / ml, and stored at -80°C for later use.

[0046]It should be noted that: in the present invention, any one or a combination of at least two of the five Escherichia coli that can cause diarrhea in piglets can be used as an antigen to immunize laying poultry. However, in order to obtain a better bacte...

Embodiment 2

[0051] The preparation of embodiment 2 egg yolk liquid

[0052] 1) Sampling and storage of eggs. Raw eggs go through strict sensory inspection, physical and chemical inspection and microbiological inspection according to fresh egg hygienic standard GB2748-2003, especially pesticide residues, drug residues, heavy metals and pathogenic bacteria. The storage conditions are 4-15 degrees Celsius temperature conditions and about 80% relative humidity. Place it in a fixed clean storage area to store enough supply for 7 days egg production.

[0053] 2) Cleaning and disinfection of the upper (loading) immune eggs and immune eggs. The operator places the egg trays on the rotary table. The egg loader loads the eggs onto the rolling table through the vacuum nozzle. The egg loader has a special jam detection system that transfers empty egg trays to the operator. After the eggs are loaded onto the rolling table, the automatic blowback system can ensure the next round of work of the vac...

Embodiment 3

[0055] The preparation of embodiment 3 egg yolk particles

[0056] 1) Ingredients. On the basis of calculating the volume of the egg yolk liquid, weigh the microcrystalline cellulose and xylooligosaccharide according to the proportion, and add the microcrystalline cellulose and xylooligosaccharide to the In the homogenate tank containing egg yolk liquid, increase the stirring speed after all the two auxiliary materials are added to the homogenate filling, so that the three components are fully mixed.

[0057] 2) Extrude. Add the mixture into the spheronizer in batches, slowly add the mixture prepared in step 1 at a hole diameter of 4.5 mm and a rotation speed of 50 r / min, and extrude a long continuous strip solid semi-finished product with a smooth surface at the outlet of the extruder.

[0058] 3) Roll round. Collect the semi-finished products and add them to the spheronizer for spheronization. The time is about 1min. The processing speed is initially 200r / min, and then qu...

Abstract

The invention discloses an egg yolk composite feed additive and a preparation method thereof. The feed additive is prepared from a raw material mixture including yolk liquid, microcrystalline cellulose and xylooligosaccharide. The preparation method is simple and needs low cost; and the feed additive is convenient to use and has high immunological competence.

Description

technical field [0001] The invention belongs to the field of feed, in particular to an egg yolk compound feed additive and a preparation method thereof. Background technique [0002] Eggs contain a variety of effective ingredients. Egg yolk is the most nutritious part of eggs, and its total weight accounts for about 28% to 29% of the total weight of eggs. Egg yolk is not only rich in nutritional factors such as lecithin and phosvitin, which can promote the growth and development of larvae, but also contains some other functional factors against pathogenic microorganisms, such as ovomucin and cysteine ​​protease inhibitors, which can inhibit the growth and development of larvae. Hemagglutination caused by viruses and exerts antibacterial and antiviral effects through the inhibition of sulfhydryl proteins; xylic acid, xylic acid oligosaccharides, and immunoglobulins can promote larval development and anti-infection, especially for diarrhea caused by viruses. effect. On the b...
