Animal Feed Additives


For several decades, DuPont Danisco Animal Nutrition has helped animal producers resolve “profit, performance and planet” challenges and maximize the return on their feed investment through the delivery of optimized feed enzyme, betaine and probiotic technologies. The introduction and the implementation of these revolutionary industry leading technologies offers radical cost savings through enhanced animal performance and liveability. They also minimize the impact of nutrition-related environmental and sustainability challenges. The challenge of feeding the world in a sustainable way dates back to the 1960s, when population growth started to escalate, more than doubling by the turn of the century. Increasing the efficiency by which animals convert feed into protein and shortening the cycle time of production has become increasingly important. Traditional feed costs, already high at around 70% of total production budgets, have escalated in line with a growing demand for meat, fish, egg and dairy products.

Carbohydrase and protease feed enzymes.

Reducing the impact of variability by improving nutrient uptake and digestion has been DuPont Danisco Animal Nutrition main aim since delivering a series of unique products based on xylanase, amylase and protease in the late 1980s.

Phytase feed enzyme solutions

Phytase is the most widely used feed enzyme in the world, included in ~90% of poultry – and ~70% of pig – diets. DuPont Danisco Animal Nutrition highly bio-efficacious phytase feed enzymes offer unprecedented digestibility and phytate destruction benefits, increasing the availability of phosphorus, calcium, energy and amino acids to the animal.


Axtra® XB

The first enzyme combination for pigs and all poultry, including game birds. It is a combination of xylanase and beta-glucanase that improves digestibility of pig and poultry diets, based on mixed grain. Poorly digested feed reduces animal performance, increases the costs of production and lowers profitability. By targeting these fibre components, Axtra® XB improves digestion by helping release nutrients; reduces digesta viscosity; reduces the production of excessive secretions into the gut (reduced endogenous losses) and improves litter quality and faecal consistency.

Danisco Xylanase

is a preparation of endo-1,4-ß-xylanase produced by Trichoderma reesei that improves pig and poultry performance by improving nutrient uptake and minimizing the impact of anti-nutrients. Danisco Xylanase is designed and extensively tested for use in pig and poultry diets. It targets the arabinoxylan fraction of the fibre in many raw materials e.g. grains, grain by-products and vegetable protein meals. Danisco Xylanase improves digestion and reduces production costs by releasing nutrients, reducing digesta viscosity and the production of excessive secretions into the gut; reducing variability in the feeding value of grain and other raw materials, improving litter quality and faecal consistency.


is the high performance enzyme combination for poultry diets. It is a poultry-specific xylanase, amylase and protease combination that improves digestibility in a variety of diets and targets the key anti-nutrients in mixed grain poultry diets, containing vegetable protein sources. Avizyme® releases encapsulated energy and amino acids, providing a reliable solution to the feed formulation needs and opportunities for radical feed cost reduction, especially during periods when the price of protein is high.

Axtra® PHY

The fast-acting phytase to help producers and animals finish first. Axtra® PHY is a patented, highly bio-efficacious phytase, offering radical feed cost savings compared to E.Coli equivalents. DuPont Danisco Animal Nutrition animal trials and results have proven that Axtra® PHY has the highest bio-efficacy, compared to all other phytases currently available in the market. It works quickly in the digestive tract and has the highest activity at low pH. This doubles the rate of early phytate destruction to release more phosphorus overall and overcome phytate anti-nutrient effects.
