    Natuphos®

      Natuphos® makes bound phosphorus digestible

      Natuphos® is a highly efficient 3-phytase. Monogastric animals like poultry and swine lack sufficient intestinal phytase for breaking down phytate, which is present in cereal and soybean-based diets to varying extents. Hence, added to feed, Natuphos® joins the limited range of endogenous enzymes present in the gastrointestinal tract of pigs and poultry to ensure the efficient release of dietary phosphorus from phytate, thus making it readily digestible.

      Why the element phosphorus is elementary

      An essential micronutrient

      Phosphorus is an essential mineral for pigs and poultry, which require it for various biological functions. It plays a key role in bone formation and mineralization and is involved in many other metabolic processes like energy transfer as well as protein and nucleic acid assembly. Phosphorus is also one of the building blocks of cell membranes. Phosphorus deficiency causes poor bone mineralization and impairs important production parameters such as growth rate, carcass leanness and carcass quality. To ensure good animal health and performance, it is therefore essential to supply adequate amounts of phosphorus in the feed.

      Sources of phosphorus

      Feed ingredients contain varying amounts of phosphorus that is basically available for metabolic functions. However, phosphorus from feedstuffs of plant or animal origin is usually less digestible than inorganic phosphorus added to animals’ diets. The cost of inorganic phosphorus feed supplements can be quite high, depending on the supply situation. Prices are expected to rise in the long-term because known global phosphorus reserves are limited. Phosphorus use is currently increasing at a rate of over 3.2 percent annually (FAO, 2008), mainly driven by a rising need for crop fertilization. So making use of plant phosphorus by adding phytase to feed will ensure a long-term, environmentally friendly supply.

      Dosage recommendations and matrix values

    It is recommended to include the matrix values as indicated in Tab. 1a/b/c/d up to the following levels in linear programming. The efficacy of Natuphos is documented by a substantial number of scientific experiments. The following equivalences have been proven:
    Pigs  

    1,000 FTU = 1.20 g dig. P = 1.50 g P (from MCP) = 1.73 g P (from DCP)

    500 FTU = 0.80 g dig. P = 1.00 g P (from MCP) = 1.15 g P (from DCP)
    Broilers, turkeys, ducks  

    1,000 FTU = 1.04 g dig. P = 1.30 g P (from MCP) = 1.50 g P (from DCP)

    500 FTU = 0.80 g dig. P = 1.00 g P (from MCP) = 1.15 g P (from DCP)

    500 FTU/kg = 100 g Natuphos 5000 per metric ton of feed/ 50 g Natuphos 10000 per metric ton of feed

    1,000 FTU/kg = 200 g Natuphos 5000 per metric ton of feed/100 g Natuphos 10000 per metric ton of feed
    Laying hens  

    600 FTU = 1.04 g dig. P = 1.30 g P (from MCP) = 1.50 g P (from DCP)

    300 FTU = 0.80 g dig. P = 1.00 g P (from MCP) = 1.15 g P (from DCP)

    300 FTU/kg = 60 g Natuphos 5000 per metric ton of feed/ 30 g Natuphos 10000 per metric ton of feed

    600 FTU/kg = 120 g Natuphos 5000 per metric ton of feed/ 60 g Natuphos 10000 per metric ton of feed
