AB VISTA UNVEILS INDUSTRY’S FIRST DUAL


ACTION MICROBIOME ACTIVATOR AT IPPE A breakthrough dual action product, designed to accelerate the development of a fibre-degrading microbiome, has been launched by AB Vista at the IPPE Expo in Atlanta, USA. Signis – a unique xylanase and fermentable xylo-


oligosaccharide (XOS) combination – accelerates the development of a fibre-degrading microbiome, enabling the fermentation of fibre sources that would otherwise remain undigested, and improving the extent of fibre digestibility earlier in the monogastric life cycle.


At this time, the product is available in North America, Europe, India, Australia and New Zealand. Dr. Mike Bedford, Research Director from AB Vista, explains


that the product is a result of years of research looking at the beneficial effects of fibre breakdown products on gut function and animal performance: “The industry has seen a series of interconnected shifts


in recent years, with a reduction in antibiotic use leading to a focus on gut health, which in turn has prompted feed companies to investigate nutritional strategies aimed at stimulating the gut microbiome. “Over the last six years, through our research we have been


observing the connection between the production of certain fibre- breakdown products, the gut microbiome and improved animal performance. What we know is that certain xylo-oligosaccharides


ZINPRO LAUNCHES AVAILA® SE


ACROSS THE EU Zinpro Corporation’s Availa-Se (zinc-L selenomethionine) is now available for purchase following recent regulatory approval in the EU for all-species use. “It’s well known in the animal nutrition


business how robustly the EC examines products before approval,” says Michael Bain, area manager – Europe and South Africa, Zinpro Animal Nutrition. “Availa-Se not only received approval, but also obtained recognition as a unique molecule, with its own specific registration number – 3b818, making it distinct from any other selenium product in the EU.” “Availa-Se is based on unique molecule


that offers superior nutrition-related performance in the animal,” he adds. “It will


produced by xylanases act as ‘signals’ for the gut microbes to develop a more effective fibre-degrading capacity over time. This is the core concept behind Signis and where the product derives its name, from its signalling effect.” Signis has been proven to speed up the development of


fibre-degrading bacteria in the gut of both swine and poultry. The product contains a combination of a xylanase and fermentable xylo-oligosaccharides, selected specifically for their beneficial effect on hind-gut fermentation. Dr. Bedford outlines the mechanism of action – and explains what this means in real terms for producers: “Signis works via a dual action: xylanase hydrolyses fibre,


increasing fermentability and roughening the fibre surface for bacterial attachment, whilst xylo-oligosaccharides signal to the microbiome to develop its ability to ferment arabinoxylan as fast as possible. “This signalling results in adaptive changes towards a


greater capacity to degrade fibre, effectively, enabling greater diet digestibility by improving the extent of fibre digestibility at a younger age than would normally occur. The end result for producers is improved nutrient digestibility, improved performance and an overall reduction in production costs.” More information on Signis can be found at www.abvista.com/Signis For more information, contact AB Vista on +44(0)1672 517 650 or info@abvista.com.


be sold as a one-source organic selenium product across all species, including ruminant, swine, poultry, aqua, equine and companion animal, for combination with inorganic sources such as sodium selenite, if desired.” Availa-Se, which will be marketed in


a 2000 ppm selenium formulation across Europe, possesses a unique molecular structure that makes it the world’s first rumen bypass selenium product. “The selenomethionine in Availa-Se is absorbed and metabolised as methionine in the body,” says Christof Rapp, Ph.D., research nutritionist – Europe, Zinpro Corporation. “Methionine is an essential amino acid to build protein, so selenomethionine is easily and readily absorbed and doesn’t need to be further broken down by


digestion. Complexing our zinc to the selenomethionine molecule makes it highly soluble, absorbable, stable and readily available to the animal compared to hydroxy analogue of selenomethionine (SeMHA) and other selenium sources.” Dr. Rapp notes that 100 per cent


of the selenium found in Availa-Se is selenomethionine – a much more pure and consistent form of selenium than currently available in selenium yeast products. Also, the zinc chaperone in the Availa-Se molecule offers superior stability in the digestive system. “Because Availa-Se is readily available once ingested, it allows the animal to build selenium stores in muscle and other tissues,” he says. “These stores are utilised to better handle antioxidant needs during stressful times.”
