Abstract
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the modification of the terms of authorisation of Heyndrickxia faecalis (formerly identified as Weizmannia faecalis) DSM 32016 (TechnoSpore50®), as a zootechnical feed additive authorised for use in all poultry species for fattening, reared for laying/breeding, ornamental birds and suckling and weaned Suidae piglets.
