Audits, Quality Control, & On-Site Consulting

Hatchery audits & preparedness plans

The success of VAXXITEK® HVT + IBD depends on a suitable hatchery environment for administration—and Merial’s Vaccination Technologies and Services (VTS) group can help set up each of our customers for that success.

Whether the customer is already vaccinating at the hatchery, or needs assistance making the transition, our VTS technicians will visit the site to:

  • Audit the current physical environment and procedures already in place
  • Assess suitability for using VAXXITEK HVT + IBD and other hatchery-administered vaccines
  • Recommend the most appropriate vaccination mode (in-ovo or subcutaneous) and specific equipment solutions
  • Develop technology integration and change management plans
  • Provide comprehensive audit reports to clearly communicate findings and guide staff through next steps

A focus on maintaining quality

Whether in the hatchery or on the farm, maintaining ongoing vaccination quality is a top priority for every poultry business. Our VTS teams help customers optimize their processes around quality control and biosecurity, identify potential points of vulnerability, and preempt issues. Regular site visits for monitoring quality are an integral part of the VTS offering.

We work closely with our Veterinary Services group to provide scientific diagnostic and monitoring tools, and we develop supporting products and programs such as dyes that help monitor injection quality, incentive contests to encourage staff compliance—and much more. Talk to your VTS representative, or contact us, to discuss a quality control plan for your operation.
