Embodiment 1

[0019] A preparation method of yolk antibody feed additive powder, comprising the following steps:

[0020] 1) After washing and disinfecting the high-free eggs, use an egg separator to separate the egg white and egg yolk, and stir the egg yolk evenly to obtain egg yolk liquid;

[0021] 2) Mix egg yolk liquid and corn flour in a weight ratio of 1:2, and mix well;

[0022] 3) Add potassium sorbate according to the weight of acid clay or corn flour, the dosage is 0.2-1.0g / kg, and stir evenly;

[0023] 4) Put the mixture obtained in step 3) in an oven and dry at 50° C. for 3-5 hours to obtain egg yolk antibody feed additive powder.

Embodiment 2

[0025] Same as the above-mentioned Example 1, the difference is that the egg yolk liquid and corn flour are mixed in a weight ratio of 1:4.

Embodiment 3

[0027] Same as above-mentioned Example 1, the difference is: the egg yolk liquid and corn flour are mixed in a weight ratio of 1:6.

Abstract

The invention discloses a preparation method and application of yolk antibody feed additive powder. The preparation method is characterized by comprising the following steps of: (1) washing and disinfecting high-immunity eggs, separating egg white from yolk by using an egg separator, and uniformly stirring the yolk to obtain yolk liquid; (2) mixing the yolk liquid with acid clay according to a weight ratio of 1: (2-8) or mixing the yolk liquid with corn flour according to a weight ratio of 1: (2-8), and fully and uniformly mixing; (3) adding potassium sorbate into the mixed liquid obtained in the step (2), and uniformly stirring; and (4) putting the mixture obtained in the step (3) into a drying oven, and drying at 50 DEG C for 3-5 hours to obtain the yolk antibody feed additive powder. The yolk antibody feed additive powder has the advantages of low moisture content, unchanged antibody titer and simple and feasible preparation method.

Description

technical field [0001] The invention relates to a preparation method of egg yolk antibody, in particular to a preparation method of egg yolk antibody feed additive powder and its application. Background technique [0002] Yolk immunoglobulin (Immunoglobulin of Yolk, referred to as IgY), also known as yolk antibody. When a laying hen is immunized with a specific antigen, a large amount of corresponding specific polyclonal antibody IgY can be produced in the chicken serum and rapidly transferred and accumulated (about 15 days) in the yolk. IgY has a unique molecular structure, stable properties, and diverse functions. It has been widely used in immunoassays, biochemical assays, human food (mainly infant food), cosmetics and other fields. In addition, IgY is also a new type of feed additive, which has been used to promote the growth and reproduction of livestock and poultry and prevent and treat diseases (main digestive tract diseases), overcoming the drug residues and drug re...
