AB VISTA LAUNCHES THE WORLD’S FIRST ‘STIMBIOTIC’
PRODUCT AB Vista has launched a new functional additive and the world’s first ‘stimbiotic’ product, Signis, a dual acting combination of xylanase and xylo-oligosaccharide that accelerates the development of a fibre- degrading microbiome, which in turn: increases nutrient digestibility; enables improved fermentation of fibre sources that would otherwise be un-degraded; and delivers consistent animal performance and reduced production costs. “The concept of stimbiotic involves
products that have the ability to stimulate the development of a fibre fermentable microbiome,” explained AB Vista’s Research Director Dr Mike Bedford. “The stimbiotic concept is different to
how prebiotics are described; rather than adding a product in high concentration to be used as a substrate for hindgut fermentation, the stimbiotic concept is about including a low concentration of products that are used as a signal or kickstarter, driving the microbiome to ferment the fibre that is already present in the gut.” As the global feed industry continues
to reduce the usage of growth-promoting antibiotics (AGPs), the industry is turning to new tools to address the challenges that arise from such a shift. Stimulation of the gut microbiome is an emerging strategy to improve animal performance.
species for meat production for the reduction of Salmonella contamination on carcasses. The strain S. c. boulardii CNCM I-1079, which was the first and only feed additive authorized in the EU with a food safety application in 2017, can now be used in all poultry species for meat production. Poultry meat represents a food source
often associated with potential pathogens. According to the 2017 EFSA survey on zoonosis, close to 32% of turkey meat samples (n=1,000 samples from 10 member states) and 37% of broiler meat samples were contaminated with Campylobacter. Salmonella positive samples represented 4.2% of turkey meat (n= 4,000 samples), and 4.9% of the broilers samples. The mode of action of the live probiotic
yeast strain S. c. boulardii CNCM I-1079 is well understood, as are its beneficial effects in the digestive tract, particularly its unique properties supporting a balanced intestinal microbiota and reinforcing natural defences. The demonstrated benefit of S. c.
LALLEMAND ANNOUNCES EU APPROVAL FOR PROBIOTIC YEAST LEVUCELL SB FOR USE IN
TURKEYS Lallemand Animal Nutrition has announced that its live yeast probiotic strain Saccharomyces cerevisiae boulardii CNCM I-1079, LEVUCELL SB, is now authorized in the European Union as a zootechnical feed additive for turkeys and minor poultry
boulardii CNCM I-1079 on poultry carcass contamination is a visible effect of the action of the probiotic. LEVUCELL SB benefits the gut microbiota balance, which is a key player in the bird’s digestive and immune physiological functions. Beyond the positive impact on carcass contamination, LEVUCELL SB also helps improve the farm’s performance and reduces the risk of digestive disorders caused by
E.coli, Clostridium perfringens or other agents responsible for non-specific enteritis (Delpont et al., 2015; Mathis et al., 2014). S. c. boulardii is known to reinforce epithelial tight junctions by reducing the bacteria‘s capacity to adhere to the animal’s epithelial cells (Czerucka et al., 2000). This can improve gut barrier function and help reduce the translocation of undesired bacteria to the mesenteric nodes and blood. “In the global context of fighting
antimicrobial resistance in the EU, the reduction of antimicrobial usage in livestock production is a key target while increased
pressure is put on food safety and food quality. Salmonellosis is one of the major foodborne diseases facing the poultry industry worldwide. Salmonella control is a multi-factorial issue that concerns the entire production chain from farm to fork. Having a probiotic feed additive that is also recognized to help reduce the risk of Salmonella carcass contamination is an opportunity for the whole food chain,” commented Jean-Baptiste Soula, Technical Support, Poultry, Lallemand Animal Nutrition.
BACTOCELL PROBIOTIC NOW AUTHORIZED FOR USE IN
PULLETS … Lallemand Animal Nutrition announced that its probiotic bacteria BACTOCELL - Pediococcus acidilactici CNCM I-4622 (MA 18/5M) is now authorized in Europe as a zootechnical feed additive for all avian species for fattening, for laying and rearing for laying (i.e. pullets). BACTOCELL was already authorized
in laying hens and broilers as well as in minor avian species for laying and fattening. It is available under BACTOCELL and BACTOCELL DRINK, a water-soluble formulation for applications both in poultry feed and watering systems.
… AND THE RENEWAL OF THE AUTHORIZATION OF THE PROBIOTIC BACTOCELL FOR USE
IN AQUACULTURE Lallemand Animal Nutrition have also announced that the authorization of its probiotic bacteria BACTOCELL - Pediococcus acidilactici CNCM I-4622 (MA 18/5M) - as a zootechnical feed additive for use in aquaculture has been renewed by the European Commission. It is authorized in all fish and all crustaceans, including ornamental species. P. acidilactici CNCM I-4622 remains the only probiotic authorized for use in aquaculture in the European Union.
