Bringing broiler bird feed efficiency from good to top level:
solid, confirmed proof, more than ever essential By Dr. Sven Keller, Sr. Technical Service Manager Central EU, Novus Deutschland GmbH
Over the years a variety of eubiotic feed additives and strategies for poultry have been developed, focusing on improving gut health in one or another way. All, however, aimed ultimately to achieve sustainable and efficient bird production. For many producers it is becoming increasingly difficult, therefore, to decide which solution will deliver the most efficient and beneficial results for their business. Recently the European Commission approved a unique preparation containing benzoic acid embedded in a lipid matrix, which has been marketed for several years as a premixture under the brandname AVIMATRIX® (Novus International), as a Zootechnical Feed Additive, capable of increasing performance of chickens for fattening and chickens reared for laying (Regulation (EU) 2018/982). Confirmed, by several independent studies in broilers according to the strict European Food Safety Authority (EFSA) guidelines, that it can significantly reduce feed conversion ratio (FCR), a final positive conclusion was reached resulting in its valuable classification. This feed additive preparation, which for use in its authorized species is available under a new brandname AVIMATRIX®
Z,
provides broiler operations in particular with a unique eubiotic with a guaranteed efficacy independently confirmed by European authorities, to raise feed efficiency for more final production profit.
Raising feed efficiency, confirmed by EFSA Due to a demonstrated, slow release activity in the intestinal tract of birds, AVIMATRIX Z establishes a healthier microbiota equilibrium, improving litter quality and foot pad health with a clear gain in broiler performance as the main final advantage (Figure 1).

of broilers is often not a simple, given fact for many eubiotic solutions in the market. AVIMATRIX has been successfully applied in various experimental facilities and commercial broiler productions across Europe, now even more supported in reliability by the recent Zootechnical Feed Additive approval1
. The most recent trial contributing
to the EU authorization, proving the core objective of AVIMATRIX Z, was carried out at the Olsztyn University of Warmia and Mazury, Poland. A total of 1100 Ross 308 broilers were divided into two groups, with 25 pens per treatment and 22 animals per pen. The inclusion of AVIMATRIX Z at 500g/t in the diet for 35 days resulted in a significantly
