NEWS 22 FEED & ADDITIVE MAGAZINE July 2025 Kemin Industries announced the expanded approval of Clostat® for all pig categories within the European Union. The authorization was published in the Official Journal of the European Union on 19 December 2024, following a scientific opinion from the European Food Safety Authority (EFSA) — adopted on 5 January and published on 26 February 2024 — confirming the safety and efficacy of Bacillus velezensis ATCC PTA‐6737 (formerly Bacillus subtilis) as a gut flora stabiliser for pigs for fattening, piglets, and sows. The authorization is valid from 8 January 2025, for a period of 10 years. For over 20 years, Clostat has helped pig producers worldwide enhance microbiome management and reduce reliance on antibiotics for preventive intestinal health. Previously approved for sows and post-weaning piglets, Clostat is now available for the entire pig production cycle, providing a consistent, research-backed approach to microbiome management — from farrowing to finishing. Clostat contains Bacillus sp. PB6, a naturally occurring probiotic strain that helps balance the gut microbiome and mitigate harmful bacteria, such as Clostridium spp. This mode of action has demonstrated significant benefits across the three different production stages: • Sows – Helps maintain gut balance, improving reproductive performance and litter uniformity. • Piglets – Supports early gut development, reducing digestive disturbances and promoting stronger growth. Fattening Pigs – Enhances growth performance, leading to a higher final weight and improved feed efficiency.

The research shows that supplemented pullets had better bone mineralization via a unique modulation of bone metabolic pathways. The avian bone health is a key factor for extending the laying cycle and improving hens’ welfare. The objective of the study was to investigate the effect of a standardized dry grape extract (SDGE) on bone quality and metabolome of future laying hens reared in commercial conditions. The results of the study showcase that the pullets supplemented with Nor-Grape® exhibit significant enhancements in several key areas compared to the ones in the control group, such as: • Enhanced bone mineral status showed by higher bone-dry matter, calcium and phosphorus content; • Fewer bone deformities, supporting better animal welfare; • Benefits explained by a unique modulation of bone metabolic pathways; • Results achieved without any modifications of feed content in calcium, phosphorus or enzymes. In this study, pullets receiving Nor-Grape® entered the laying phase with an improved bone health. The results showcase the unique and advanced modes of action of Nor-Grape® and add to the growing body of evidence supporting its efficacy, Nor-Feed points out.
