Enterococcus faecium (DSM 7134)

What it is. Microbial additive based on Enterococcus lactis (formerly identified as Enterococcus faecium) DSM 7134, produced by fermentation and supplied as a powder or as microencapsulated granules. The composition guarantees a minimum level of viable cells per gram of additive, as set out in the authorisation annex.

What it is for. Classified as a zootechnical additive, functional group 4b, gut flora stabiliser, for chickens for fattening, chickens and pullets reared for laying, minor poultry species, laying hens, weaned piglets, fattening pigs and sows (including via drinking water). It is intended to support intestinal microbial balance in these species and categories. A related EFSA opinion also assessed a combined preparation with Lacticaseibacillus rhamnosus DSM 7133 for rearing calves; an associated trial explored spray application in day-old broiler chicks in a bacterial challenge model, illustrating one possible research use without setting a use level.

Points to watch. Use instructions must specify storage conditions and thermal processing stability. For sows, a minimum content of 5 × 10^8 CFU applies per the annex; operators must implement operational procedures and, where risks cannot otherwise be controlled, personal protective equipment including eye, respiratory and skin protection is mandatory during handling.
