Safety and efficacy of a feed additive consisting of endo-1,3(4)-beta-glucanase produced by CBS 589.94 (RONOZYME® VP (CT/L)) for chickens for fattening and weaned piglets (DSM Nutritional Products AG).

Following a request from the European Commission, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of endo-1,3(4)-beta-glucanase produced by CBS 589.94 (RONOZYME® VP (CT/L)) as a zootechnical feed additive for chickens for fattening and weaned piglets. Based on the no observed adverse effect level identified in a subchronic oral toxicity study in rats and the tolerance trials provided, the additive was considered safe for chickens for fattening and weaned piglets at the proposed conditions of use. The Panel also concluded that the use of the product as a feed additive does not rise concerns for consumers and the environment. Owing to the lack of data obtained with the final formulations, the Panel could not conclude on the potential of the additive to be irritant to skin and eyes or on its potential as a dermal sensitiser. Due to the proteinaceous nature of the active substance, the additive is considered a respiratory sensitiser. The Panel concluded that the additive is efficacious as a zootechnical additive in chickens for fattening and weaned piglets at the minimum recommended level of 10 FBG/kg feed.
