To assist veterinary supervisors, farm managers, and procurement specialists in making fully informed decisions, we have compiled detailed answers to the most common technical inquiries regarding our combined inactivated vaccine.
Q: Why is it crucial to allow the vaccine to reach room temperature before injection?
A: Administering a cold vaccine can cause significant thermal stress to the birds, potentially leading to adverse reactions. Furthermore, allowing the water-in-oil emulsion to reach room temperature optimizes its viscosity, making it much easier to draw into syringes and inject smoothly, which ensures highly accurate dosing and reduces equipment wear.
Q: Can this inactivated vaccine be used as the sole immunization against ND and IBD?
A: For optimal, comprehensive protection—especially in highly endemic areas—it is strongly recommended to use this inactivated vaccine in conjunction with live vaccines. Live vaccines stimulate immediate local mucosal immunity (respiratory and intestinal tracts), while our inactivated emulsion provides long-lasting, systemic circulating antibodies.
Q: What happens if the vaccine is accidentally frozen during transport or storage?
A: Freezing causes the delicate water-in-oil emulsion to break or separate permanently. This destroys the critical slow-release mechanism and can lead to severe local tissue reactions or a complete loss of immunological efficacy. Any vaccine that has been frozen is strictly prohibited from use and must be discarded safely.
Q: How should I manage the withdrawal periods if I am raising dual-purpose birds?
A: The withdrawal period is strictly based on the final end-use of the bird. If the birds are destined for meat processing as broilers, a 21-day withdrawal period applies. For all other categories, including spent breeding hens being sent to slaughter, a strict 42-day withdrawal period must be observed to comply with international food safety regulations.
Q: Is it absolutely necessary to use the entire bottle once it has been opened?
A: Yes. Once the sterile rubber seal is punctured, the risk of environmental contamination increases significantly. To ensure absolute biosecurity and maximum vaccine efficacy, the entire contents of the bottle must be used on the day of opening. Any remaining emulsion should be disposed of via appropriate, harmless biological waste methods.
To be used only under veterinary supervision.
