Nutrient sparing enzyme based monogastric concept


Gilson Gomes, head of global technical, AB Vista, told us:

“It was launched last year, the MMN concept is not about phytase only, it is about combining phytase with xylanase,gathering more information also on the energy content of feed, and trying to maximize the effect of both enzymes together,” ​he said.

The concept is said to improve nutrient utilization and enable a significant improvement in the utilization of amino acids, minerals and energy, resulting in feed cost savings and minimizing waste.

“Essentially, MMN is an amalgamation of all the information we have gathered in the past 10 years in terms of analyzing feed, of gaining greater understanding of the effects of enzymes, combined with insights into the anti-nutritive effects of phytate and non-starch polysaccharides (NSPs),”​ Gomes told us.

Validated in performance trials in broilers and swine, the company claims the application of its MMN concept can generate cost savings of up to £12 per ton, when compared to a conventional diet formulated to include a standard dosage level of enzymes. Furthermore, in sustainability studies it has run on MMN, it said it demonstrated a 3% reduction in the carbon footprint of broiler production.

Alternative to superdosing

The MMN approach emerged as an alternative to the company’s superdosing method, the practice involving the use of high doses of phytase to target phytate (IP6) destruction, which became commercially available in 2011, said Gomes.

“The challenge was that, in some regions, in Europe, for example, the superdosing concept was not adopted so readily, due largely to the fact that the structure of European animal production is different, or is less integrated than production in North America,” ​he said.
