The EU assesses the efficacy of Lactobacillus plantarum strains ATCC 55058 and ATCC 55942 as feed additives for all animals

On 31 October 2022, according to the European Food Safety Authority (EFSA), at the request of the European Commission, The European Union Study Group on Animal Feed Additives and Products (FEEDAP) has issued a scientific opinion on the efficacy and effectiveness of Lactiplantibacillus plantarum strains ATCC 55058 and ATCC 55942 as feed additives for all animals.

After evaluation, the panel concluded that the addition of Lactobacillus plantarum strains ATCC 55058 and ATCC 55942 had the potential to improve the silage process. Part of the original report is as follows:

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the efficacy of two technological additives to improve ensiling of forages consisting of Lactiplantibacillus plantarum (formerly Lactobacillus plantarum) strains ATCC 55058 and ATCC 55942, respectively, for all animal species. Both additives are intended for use with all forages and for all animal species at a proposed forage. forage. In two previous opinions, forage of 5 ×106 colony forming units (CFU)/kg. the FEEDAP Panel could not conclude on their efficacy due to the absence of any significant evidence of nutrient preservation. based on three new efficacy studies provided by the applicant as supplementary information, the FEEDAP Panel concluded that the addition of L. plantarum strains ATCC 55058 or ATCC 55942, have the potential to improve the ensiling process by reducing protein degradation in all type of forages as indicated by the reduction of ammonia production.
