Phytase helps win the fight for dietary phosphorus

As the demand for phosphate fertilizers continues to rise to meet increases in global crop production to feed developing nations and produce ethanol, feed producers face the challenge of sourcing sufficient quantities of feed phosphates to meet animal requirements.

Feed phosphate prices have rocketed in recent months, reflecting the imbalance between global supply and demand. The UK's Agricultural Industries Confederation has recently reported that over the coming months supplies of feed phosphate will continue to be limited, which means that the price of feed phosphate will continue to rise.

New generation bacterial phytases have been shown to be more effective at releasing plant-bound phytate phosphorus than traditional fungal phytases. At a standard inclusion rate of 500 FTUs/kg feed, Danisco’s bacterial phytase (Phyzyme XP) can replace an additional 1.3 kg dicalcium phosphate (DCP) in pig and broiler feed formulations, compared to traditional fungal phytases.

“With the current phenomenal rise in the price of feed phosphates, producers should consider increasing the inclusion of phytase in their feed”, explains Dr Peter Plumstead, Danisco’s Technical Services Manager.

“We have a wealth of data to show that doubling the dose of phytase in pig and poultry feed allows at least an additional 1.9 kg dicalcium phosphate to be removed from the feed, without negatively affecting animal performance,” Peter continues.

500 FTUs /kg feed tends to be the standard phytase inclusion rate in broiler and pig feeds and 300 FTUs/kg feed for layer feeds. With current DCP prices at around €550/tonne, the economic optimum phytase inclusion rate is currently around 1000 FTUs/kg feed for broiler and young pig feeds and 600 FTUs/kg feed for layer diets.

“1000 FTUs/kg feed will currently reduce broiler feed costs by around €4.60/tonne. This allows a further 17% reduction in dicalcium phosphate, resulting in an additional feed cost saving of €0.60/tonne compared to the standard inclusion rate of 500 FTUs/kg feed. Increasing the phytase dose to 600 FTUs/kg feed will allow layer producers to further reduce their feed formulations costs by around €0.53/tonne, reducing dicalcium phosphate inclusion by around 30%” Peter concludes.

Danisco Animal Nutrition Achieves FDA Agreement for Highly Cost Effective Phytase Dose for Swine

MARLBOROUGH, UK, June 5, 2013 - Danisco Animal Nutrition, a business segment of DuPont, will celebrate over 25 years of animal nutrition innovation at World Pork Expo in Iowa by showcasing tried and tested nutritional solutions to help overcome key challenges currently facing the pork industry worldwide. As animal producers face rising feed prices as a result of weather volatility, escalating oil costs and other market factors, it will become increasingly important to improve the efficiency by which animals convert feed into protein and to shorten the cycle time of production.  

Achieving optimum performance and cost benefits from increasingly complex mixes of raw materials is an issue facing all animal producers and we have a rich heritage of providing innovative new solutions to help them achieve these goals. For example, our innovative, patented bacterial phytase, Axtra® PHY, minimizes the anti-nutrient and energy draining effects of phytate throughout the digestive system.  Porzyme®, a xylanase-based enzyme solution, reduces fibre-related anti-nutrient effects and improves performance and feed cost effectiveness by allowing addition of cheap fibrous energy sources - such as DDGS and wheat middlings - to corn diets. Extensive trials have shown faster and more efficient gain in pigs at all stages of growth, with economic benefits of up to $2.72 per pig in the late finishing phases. 

We will also showcase solutions that help producers to be more environmentally sustainable and spend less money on complying with increasingly strict legislation.  To use a local example, the Environmental Protection Agency’s plan for stepped-up regulation around manure management will put producers in Iowa and their 20 million hogs at the centre of a national debate on the sheer cost of compliance.  Maximizing  production needn’t mean that more resources will have to be spent on managing pollution if additives are used that improve digestibility and reduce the resulting harmful effects of animal waste.  Axtra® PHY and Phyzyme® XP, the first E.coli phytase on the market, are hugely effective in slashing manure application costs by reducing phosphorus in the manure. We are also advancing phytase thermostability with our TPT technology to ensure ease of use.

Producers can also achieve performance benefits even before piglets are born and continue to save them money as they grow using our Betafin® natural betaine solution, which will also be featured at the show.  An osmolyte and methyl donor produced in a highly-purified form from sugar beet, Betafin® natural betaine is particularly effective during the dry summer months when heat stress is an issue and fertility can also be depressed.  As a methyl donor, Betafin® natural betaine improves biological functions such as reproduction, increasing litter size and piglet vitality.  In addition, it offers wide-ranging osmolytic benefits during weaning when dehydration is a major challenge and thus helps alleviate the impact of weaning stress on piglet performance.  For grower finisher pigs, Betafin® natural betaine has been shown to improve daily lean gain via its energy boosting role. 

Gwendolyn Jones, technical services manager at Danisco Animal Nutrition commented, “Making a profit on pigs is a challenge in an increasingly volatile and regulated environment. Our goal is to develop innovative combined and single additive solutions that help pig farmers stay on course for profitable pig production in a sustainable way”
