Customer driven solutions for the global feed industry

With the global feed industry currently feeling the stress of high feed ingredient prices, the seminar provided the latest insights into how enzyme technology can ease the pressure of increasing feed costs.

Dr Peter Selle, Honorary Associate with the Poultry Research Foundation, University of Sydney, and Dr Aaron Cowieson, Senior Scientist with Danisco Animal Nutrition provided new insights into phytase inclusion in poultry diets.

Drs Selle and Cowieson both pointed out that it is not just the level of phytate in the diet that needs to be taken into consideration when using phytase. Phytate interactions with other nutrients, such as protein and fibre, may affect response to phytase. In addition, the dietary calcium:phosphorus ratio can have a substantial effect on the response to phytase addition, and should considered by nutritionists when formulating feeds.

Dr Cowieson advised that due to the current phenomenal rise in the price of feed ingredients, producers have the opportunity to further drive down costs of production by increasing the inclusion of phytase in their feed. He further recommended the use of new generation bacterial phytases, which are more effective than traditional fungal phytases, and to take account of energy and amino acid matrix values together with phosphorus and calcium.

He concluded that where 500 FTUs /kg feed tends to be the standard phytase inclusion rate in broiler feeds, with current feed ingredient prices, the economic optimum phytase inclusion rate is currently around 1000 FTUs/kg feed.

For producers feeding wheat-based diets, Dr Alexandre Péron, Technical Services Manager with Danisco, explained how nutritionists can use enzyme technology to manage wheat variability. Wheat is highly variable. Scientific literature has reported huge differences in wheat AME, from 8.5 to 15.9 MJ/kg, DM basis. Dr Péron went onto explain that because it is difficult to accurately predict the AME of wheat , feeding wheat-based diets may result in reduced growth, poor nutrient utilisation and variable bird performance.

Wheat viscosity mainly affects fat absorption, grain hardness affects starch digestibility - starch digestibility being lower in hard wheat cultivars, and fibre all contribute to variations in AME. Feed processing (grinding and pelleting) and bird genetics also impact wheat digestibility. Dr Péron reported that whilst xylanase enzymes are abundantly used in wheat-based broiler diets to improve wheat digestibility and reduce variations in bird performance, research from the University of Massey, New Zealand suggests that using phytase in combination with xylanase has additional benefits on performance of birds fed wheat-based diets.

Dr Ceinwen Gilbert, Technical Services Manager for Danisco presented the latest tools producers can use to reduce the cost of corn-based feeds. Corn is the most commonly used grain in poultry diets and widely regarded as a consistent raw material. In fact, corn can be extremely variable in terms of both its nutrient content and availability, and consequently its financial value to the feed producer.

Broiler feeds are often formulated using fixed nutrient values, which take no account of batch-to-batch variation and risk under-exploiting bird growth, feed conversion and profit. Representing a breakthrough in feed enzyme technology, Danisco’s Avicheck Corn service calculates the increase in corn energy value by enzyme addition.

She explained that including this energy matrix value into the producer’s feed formulation provides opportunities to reduce feed costs. Typically the higher energy corn replaces some more expensive high-energy ingredients, for example fat or oil.

Dr Ed Moran, Professor of Poultry Science at Auburn University, USA, comprehensively described how adding carbohydrase enzymes with phytase to corn-based broiler diets potentiates the effect of phytase in terms of improving nutrient digestibility, increasing weight gain and feed conversion efficiency and producing more lean meat.

Looking to the future, Dr David Cadogan, an eminent pig nutritionist, described how the poultry industry could benefit from adopting net energy systems used widely in the pig industry, to more accurately formulate poultry feeds.

Danisco Animal Nutrition (, a business unit of leading global ingredient specialist Danisco A/S (Denmark), pioneered the development and use of enzymes and betaine in animal nutrition. Its products are now widely used by poultry and pig producers throughout the world. The company’s mission is to deliver innovative, sustainable solutions that increase efficiency and safety of the food production chain in an environmentally sensitive way.

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”
