Embodiment 1

[0018] Pretreatment of immune eggs

[0019] Egg selection: choose fresh eggs and good eggs; remove damaged eggs and rotten eggs.

[0020] Egg washing: the purpose is to wash away the fungus and dirt infected on the surface of the egg, usually with a brown brush, then rinse with water and dry.

[0021] Disinfection: Immerse the dried fresh eggs in 0.1% bromogeramine disinfectant solution for 1 hour, take them out and dry them in the air.

[0022] Pretreatment of the blender: Rinse the blender (capacity 20-50 kg) with clean water inside and out, spray with 0.2% bromogeramine disinfectant for 30 minutes and set aside.

[0023] Egg breaking: Start the mixer (60 rpm), add 15 kg of sterilized whole eggs, stir for 1-3 minutes, and wait for the eggs to break.

[0024] Add fluffing agent: slowly add feed bran from the mouth of the barrel while stirring, the amount is 5 kg, and stop the machine after stirring evenly.

[0025] Drying: Take out the evenly stirred immune egg bran materi...

Abstract

A yolk antibody additive for forage is prepared from the immunized egg through disinfecting said egg and stirrer, breaking said egg, stirring while slowly adding forage bran, spreading in the oven, baking while turning it over several times, mixing it with anti-mildew agent and antioxidant, pulverizing, and vacuum packing in bags.

Description

technical field [0001] The invention relates to a preparation method in the technical field of feed industry, in particular to a preparation method of egg yolk antibody feed additive. 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 resistance...
