Title:
IMMUNIZATION-PURPOSE SUSPENDING AGENT, VACCINE SUSPENSION PREPARATION METHOD AND SPRAY-DROP IMMUNIZATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/047210
Kind Code:
A1
Abstract:
Provided is an immunization-purpose suspending agent, comprising the following raw materials in parts by weight: 15-40 parts of sodium alginate, 5-20 parts of guar gum, 2-10 parts of blow-dried powder, 1-10 parts of a surfactant, and 12-74 parts of anhydrous glucose. Accordingly, also provided are a vaccine suspension preparation method using the immunization-purpose suspending agent, and a spray-drop immunization method. The suspending agent compounded with the various components is liable to dissolve in water so as to form a viscous, uniform and stable solution, mixing the suspending agent with a coccidia vaccine dilute can maintain uniform dispersion and suspension of coccidia oocysts, and gel droplets sprayed from the suspending agent can retain moisture and has good adhesion, thereby ensuring viability of the coccidia oocysts and effective adhesion thereof on chick fluff for chick pecking, so as to establish a uniform immunity. The vaccine suspension preparation method is simple and easy to operate. Spray-drop immunization using a spray-drop device realizes uniform spray-dropping and automated immunity, and the amount of intake of vaccine suspensions of chicks is controlled by controlling the spray-drop amount.
