QUALITATIVE ANALYSIS
1.Test card reaction: Aspirate 70 ml of the serum sample to be tested, drop it into the sampling hole, time it with a timer, and leave it to stand horizontally for 20 min.
2. Result: If C-line appears, the experiment is valid; otherwise, the test should be repeated.The color of T-line is compared with the colorimetric card. If the color of 32 points on the colorimetric card is dark, it is judged as positive. Otherwise, it is negative. (Colorimetric cards should be obtained free of charge from the supplier).
VACCINE ANTIBODY LEVEL ANALYSIS
The antibody positivity, uniformity and titer of the antibodies were counted separately in groups according to breed, litter size and age.
Antibody positivity rate=Positive quantity/Total quantity*100%.
