EVONIK OFFICIALLY STARTS UP EXPANDED THREAMINO®


FACILITY Evonik has increased production capacity for ThreAMINO®


(L-Threonine) at Evonik Agroferm


Zrt., a 100 per cent subsidiary of the Group in Kaba (Hungary), to 30,000 metric tons. The fermentation and processing capacity was also increased as part of the expansion. Thanks to state-of-the-art membrane filtration and crystallization technologies, the yield achieved in the process has also increased. The additional quantities enable Evonik to meet the increasing demand for L-Threonine (feed grade 98.5 per cent) and to contribute to efficient animal nutrition.


CLARIFYING MISUNDERSTANDINGS THE KEY TO BETTER ENZYME


PERFORMANCE Understanding the negative effects of non- starch polysaccharides (NSPs) on nutrient digestibility and animal performance is the key to achieving consistent results from the feed enzymes designed to reduce them, according to AB Vista’s Senior Research Manager, Dr Nell Masey O’Neill. “Despite three decades of commercial


use, there is still little consensus on how to achieve the greatest benefits when including NSP-degrading enzymes in monogastric feeds,” she states. “This is mainly due to a poor understanding of both the NSP substrate and their interactions with NSP enzymes, and a subsequent failure to optimise NSP


enzyme use.” Whilst soluble long-chain β-glucans (in


barley) and xylans (in wheat) are the primary NSPs responsible for increased digesta viscosity, nutrient utilisation is further reduced by insoluble NSPs in plant cell walls acting as a physical barrier that limits starch and protein digestibility. In addition, certain end-products of NSP breakdown are now known to promote beneficial gut bacteria at the expense of those which may be pathogenic. “This is the reason why Econase XT –


which degrades soluble and insoluble xylans – can improve nutrient utilisation in wheat-based diets (where soluble and insoluble xylans can be problematic) and corn-based diets (where insoluble xylans dominate),” Dr Masey O’Neill- continues. “It is also why the effects of combining multiple feed enzymes into a single product are not additive, or necessarily worthwhile – any additional breakdown activity may be superfluous, or even detrimental to those beneficial end-products. “It means that individual enzyme


characteristics and dose are far more important than the number of enzyme activities present, and is why a high quality, dose-optimised single enzyme product like Econase XT will generally provide greatest value for money and return on investment.” Clarifying misunderstandings around


NSPs, their impact on animal performance and how to optimise NSP enzyme use will be a key focus at the International Non- Starch Polysaccharide (Inspire) Forum, sponsored by AB Vista and taking place between 31st March and 2nd April 2014 in Pitlochry Scotland.

ANOTHER YEAR OF GROWTH


AND SUCCESS FOR AB VISTA Continuing to grow faster than the market during the 2012-13 financial year, international micro feed ingredient supplier AB Vista has consolidated its position as one of the strong performers in the AB Agri portfolio within Associated British Foods (ABF). Sales of the company’s Quantum Blue phytase were up 30%, with AB Vista also becoming the second largest global supplier of natural betaine during the year. As the agribusiness division of ABF,


AB Agri also grew its profits, with ABF itself posting another set of excellent results that showed earnings growing to £1,185m. It was a year of successes that saw AB Vista increase staff numbers by 30, set up new offices in the USA (Florida and Janesville), Singapore and Brazil, and open a liquid betaine storage facility in Europe. Much of AB Vista’s growth has been


driven by the success of its latest generation Quantum Blue feed enzyme, which has gained a substantial market share within the phytase sector. As a result, AB Vista has been working closely with sister companies within ABF to expand production capabilities, securing additional enzyme fermentation capacity at AB Enzymes in Finland, and supporting PGP International in opening a new state-of-the-art enzyme extrusion facility in Indiana, USA.
