Safety and efficacy of a feed additive consisting of l‐lysine sulfate produced using Corynebacterium glutamicum KCCM 80368 for all animal species (CJ Europe GmbH)

EFSA Journal, Volume 24, Issue 3, March 2026.
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of l‐lysine sulfate produced by fermentation using the genetically modified strain of Corynebacterium glutamicum, KCCM 80368, as a nutritional additive in feed for all animal species and categories.

Effect of Diet Supplementation with Two Yeast Cultures on Rumen Fermentation Parameters and Microbiota of Fattening Sheep In Vitro

Microorganisms
Yeast culture can improve ruminant health and reduce economic losses in intensive farming, but as a non-standardized product in China, its quality and efficacy vary significantly.

In vitro dynamics of rumen microbiota and fermentation profiles with Antler growth of Sika deer

Microbiology Spectrum
The rumen microbiota plays a vital role in the nutrient metabolism affecting the growth of velvet antler. However, the fermentation patterns and dynamics of the rumen microbiota across growth stages of velvet antler remain largely unexplored.

Feeding Astragalus membranaceus Root Improves the Rumen Fermentation Rate in Housed Goats through the Alteration of the Rumen Community Composition

Microorganisms
Although Astragalus membranaceus root (AMR) has been noted as an ingredient in ruminant feed, the impacts of AMR feeding on rumen fermentation and the microbial community structure within the rumen are yet to be evaluated.

Partial replacement of corn silage with sorghum-sudangrass silage improves growth performance and rumen function in Hu sheep via microbial and metabolic modulation

BMC Microbiology
Background The rumen hosts a diverse microbial community and serves as a natural bioreactor that efficiently utilizes plant biomass. To explore the potential of sorghum-sudangrass silage (SS) as an alternative to whole-plant corn silage (WS), this study ...

Potential Role of Inulin in Rumen Fermentation

, 2010
The objective of this in vitro experiment was to examine the potential effects of inulin (0, 2 and 4%) at different forage / concentrate ratio (20 / 80, 40 / 60 and 60 / 40) on rumen fermentation variables during 48h long incubation. Fermentation Of pore inulin produced lower lactate and acetate but higher propionate and butyrate than the basal Mixture
