Several feed additives were granted EU marketing authorization this month.

Eppen Biotech’s L-arginine, produced by Corynebacterium glutamicum CGMCC 20516, has been approved​ for use in the EU as a feed additive for all animal species.

The additive is intended to be used in feed and water for drinking for all animal species and categories. EFSA found it was an efficacious source of the essential amino acid l‐arginine.

For the supplemental l‐arginine to be as efficacious in ruminants as in non‐ruminant species, it requires protection against degradation in the rumen, noted a scientific opinion from the European Food Safety Authority (EFSA).

The Authority also concluded in its June 2022 opinion that, under the proposed conditions of use, the additive does not have an adverse effect on consumer safety or the environment, or on animal health when supplemented in appropriate amounts and according to the nutritional needs of the target species.

Nutritional imbalances caused by the simultaneous administration of L-arginine via water for drinking and feed must be prevented.

Enzyme approvals

Kemin’s xylanase, a preparation of endo-1,4-beta-xylanase produced by Komagataella phaffii ATCC PTA-127053, was also authorized​ by EU regulators in March. It is a feed additive for use with laying poultry.

The enzyme is classified as a zootechnical additive, a digestibility enhancer.

EFSA concluded that the additive is safe and has the potential to be efficacious for laying hens when added to feed at 45 000 U/kg. Those conclusions can be extrapolated to all laying poultry species, said the Authority.

In addition, BioResource International (BRI) saw its xylanase, a preparation of endo-1,4-beta-xylanase produced by Komagataella phaffii DSM 33574, approved​ as a feed additive in the EU for all poultry species.

Phytogenics-based product broadens coverage

DSM also secured EU authorisation in March for a phytogenics-based product, a preparation of carvacrol, thymol, D-carvone, methyl salicylate and L-menthol, extending an existing authorisation to allow the product be used in turkeys and some of other avian species.

“As we invest in further innovation to support producers with science-based technologies, we expect phytogenics to play a growing role in our suite of gut health solutions,” Dr Mohammad Vadiei, global eubiotics manager at DSM, told this site.

He added that the company's aim is to deliver cutting-edge solutions that improve animal gut health, increase producer profitability and support sustainability.
