[0011] Example 1 Static test of oocyst sedimentation

[0012] 1 Materials and methods:

[0013] 1.1 Coccidia oocyst mixture: containing Eimeria tenella, Eimeria tenella, E.necatrix, E.maxima and pile-type Eimeria 4 species of worm (E.acervulina) were mixed at a ratio of 1:1:1:1, and a coccidiosis vaccine solution with 1 million oocysts / ml was formulated with 2.5% potassium dichromate solution.

[0014] 1.2 Test grouping and treatment:

[0015] One group: Shake the coccidia oocyst mixture fully, absorb 2ml and add it to 1000ml drinking water, stir repeatedly from different directions (clockwise, counterclockwise, up and down); weigh 7g of the suspension-improving powder of the present invention, and slowly add In the above-mentioned coccidian oocyst liquid, stir repeatedly from different directions (clockwise, counterclockwise, up and down) while adding, until the suspending agent is completely dissolved, and the coccidia oocyst liquid is paste.

Abstract

A suspending aid for the coccidiosis vaccine of chicken is prepared proportionally from carboxymethyl cellulose, oligose and drying powder. It can suspend the coccidian ovisacs in drinking water for at least 6 hr.

Description

Technical field: [0001] The present invention relates to the invention belonging to the veterinary vaccine immunization suspending agent, more precisely, the present invention is a coccidiosis vaccine suspending agent with a suspending effect as long as more than 6 hours composed of various components, It is possible to adopt the drinking water inoculation method without first stopping the water for the immunization route of the coccidiosis vaccine. Background technique: [0002] Chicken coccidiosis is one of the most serious diseases that harm the intensive chicken industry, and its harm to chickens is equivalent to some severe infectious diseases. So far, the main means of chicken coccidiosis control is to use anticoccidial drugs for chemical control. However, with the widespread and continuous use of anticoccidial drugs, the two major problems of drug resistance and drug residues are becoming more and more serious. The research on preventing coccidiosis in chickens throu...
