Chicken Flock Live Vaccine Immunization Operation Guide and Precautions

Chicken Flock Live Vaccine Immunization Operation Guide and Precautions

To ensure the health and productivity of chicken flocks, vaccination is an indispensable step. However, in practical operations, some farmers may overlook certain details when administering vaccine immunizations. Today, we will focus on the precautions for live vaccine immunization to help you better complete this crucial task.

I. Preparation and Administration of Live Vaccines

1. Immediate Preparation: Live vaccines should follow the principle of "prepare and use immediately," avoiding early preparation. When preparing the vaccine, it should be done quickly, aiming to complete it within the shortest time possible, usually no more than 3 minutes for preparation and no more than 1 hour for use, to ensure its activity and effectiveness.

2. Diluent Temperature Matching: The temperature of the diluent used for preparing the vaccine should be consistent with the vaccine temperature to prevent vaccine inactivation due to temperature differences.

II. Preparation Principles and Environmental Requirements

3. Frequent and Small Preparations: When preparing the vaccine, follow the principle of "frequent and small preparations" and pay close attention to the usage time to ensure that every drop of vaccine can exert its maximum effectiveness.

4. Aseptic and Light-Protected Environment: The vaccine preparation process should be conducted in an environment that is as aseptic as possible, while avoiding direct sunlight and strong winds to protect the integrity and stability of the vaccine.

III. Dropper Bottle Operation Details

5. Dropper Bottle Angle: When administering the vaccine, the angle of the dropper bottle should be kept perpendicular to the direction of the chicken's eyes to ensure that the vaccine is accurately dripped into the eye.

6. Dropper Bottle Distance: The distance between the dropper bottle and the chicken's eyes should be controlled within 1-2 centimeters. A distance that is too high may result in vaccine wastage, while a distance that is too low may lead to an insufficient dose.

IV. Vaccine Absorption Judgment and Dropper Bottle Selection

7. Vaccine Absorption Judgment: When the vaccine is dripped into the chicken's eye, if the chicken blinks, it indicates that the vaccine has been absorbed. If one eye has issues or does not absorb the vaccine, consider administering a supplementary dose.

8. Dropper Bottle Selection: Choosing the right dropper tip is crucial for vaccine immunization. During the immunization process, minimize the up-and-down movement of the dropper bottle to maintain the stability and accuracy of the dropper tip.

By following these precautions, you can more effectively carry out chicken flock live vaccine immunization work, providing robust protection for the health and productivity of the flock.
