Which strategy should be employed to promote the potential of plant extracts based products? In Europe, additives are generally classified in 5 categories defining the extent of their effects. According to the European regulation (reg 1831/2003 CE) the majority of products based on plant extracts are only authorized as “sensory additives”. In order to prove the real zootechnical efficacy of their product, suppliers have the possibility of submitting an authorization dossier to have it upgraded to a zootechnical additive by the European Commission (EC). The EC mandates the EFSA (European Food Safety Authority) to


initiate a full evaluation of the additive in order to obtain an assessment from the latter. Based on this assessment, the European Commission will be able to reclassify the product as a “zootechnical additive” category”. This assessment allows the company to communicate about performance aspects. In this context, in 2015, Pancosma, a Swiss company located in


Geneva, introduced the first zootechnical additive for broilers based on natural active ingredients to the European market. This project, initiated in 2013 in collaboration with EFSA, unified and mobilized the company’s skills and labour for one singular goal: to meet the requirements of the EFSA’s specialists. The dossier included information about the raw materials (manufacturing, purity, safety, etc.), the traceability of active ingredients (transparent formula) in the pure product or in final feed, the manufacturing process and quality control. Then, the assessment addressed performance effects. Following the reception of a positive opinion in February 2015, a publication in the official journal legalized the new status of the product in September 2015.


A mode of action identifi ed and an effi cacy scientifi cally demonstrated Over the years, XTRACT®


Trials submitted to EFSA’s committee presented clear performance improvements in broilers receiving XTRACT® supplemented with XTRACT®


. Broilers receiving a feed at a dose of 100 g/t showed a better final


body weight and feed conversion ratio. In addition, all existing results were gathered in a meta-analysis published in 2015 (Oguey et al., 2015) showing consistency in the product’s effects (see Figure 1). In addition, widely published data have demonstrated the effect of


this additive on carcasses (yield improvement and quality of pieces). These gains are possible thanks to several product properties: • A better feed digestibility (exploitation of fats and proteins) • A better epithelium integrity of the digestive tract and an improvement in the ability to absorb available nutriments • A decrease in maintenance requirements of the animal


Evolution-B was tested in one hundred


commercial farms and universities across the world. These trials proved the reliability of the zootechnical performance results on broilers. Several external reports were submitted to EFSA for assessment during the registration process. The committee provided statistical models and guidelines to realize data analyses.


What are the benefi ts of registering on markets outside Europe? The benefits of such registration in Europe are well documented. Indeed, the customer has an additional guarantee on the reliability of the supplier and its product. What about other markets? “It was very impressive to observe the benefits of zootechnical registration outside Europe. We tend to underestimate the impact of European regulation on other countries. Indeed, lots of countries exporting to the EU are inspired by and follow our advancements closely. Those from these other countries were particularly appreciative of this registration. Finally, on the other side of Atlantic these types of natural growth promoters are very well appreciated because of the ban on antibiotics,” explains Jennifer Maurin, business development manager for plant extract ranges at Pancosma. Although it was the first additive in its category (4.d), 2 other products have more recently been awarded this status, meaning there are now three additives based on plant extracts approved for poultry by the European Union.
