Feed Additive Studies Supporting EFSA Submissions

Reliable studies for feed additive development

We design and conduct feed additive tolerance and efficacy studies in livestock to support applications for authorisation in the European Union.

Supporting feed additive authorisation

The European Food Safety Authority (EFSA) independently assesses the safety and efficacy of feed additives before they can be authorised for use in the European Union. Depending on the additive category, intended use, proposed claim and target species, an application dossier may require evidence on the additive’s identity, safety and efficacy.

Feed additive tolerance and efficacy studies

Tolerance studies evaluate the safety of a feed additive for the intended target species and may include different use levels to assess its margin of safety. Efficacy studies are designed according to the intended function and proposed claim of the additive.

Livestock expertise

We conduct studies in pigs, cattle, sheep, goats, broilers, laying hens and turkeys. Our purpose-built facility offers independent study sections and flexible group or individual housing. Where field conditions are required, studies may also be organised in cooperation with Czech farms and breeders.

Study quality

Feed additive tolerance and efficacy studies are conducted as controlled GLP-like studies with predefined protocols, documented procedures, traceable raw data and defined quality controls. Each study is designed according to applicable EU legislation and current EFSA guidance.

Why Tekrolab?

Tekrolab has conducted feed additive studies whose results were included in successful EFSA submissions, supporting products that subsequently received favourable scientific opinions and EU authorisation.
