Feed enzymes help increase the nutritional value of feed, enabling more sustainable and economical farming


Adding exogenous enzymes to animal feed improves its digestibility and allows greater nutrient absorption, enabling farmers to produce more with less in a more economical and sustainable way. In this way, feed enzymes from Novozymes support improved feed conversion ratios and faster weight gain. Contact Novozymes Animal Nutrition

The DSM-Novozymes feed enzymes alliance

By combining their complementary competences, Novozymes and DSM have been able to introduce  many innovative and successful feed enzymes to market, putting them at the forefront of feed enzyme technology. And – through the alliance – the two companies continue to bring new and more efficient feed enzymes to market quickly, to provide even greater value to the livestock industry. Below you can see how the alliance works.


The DSM-Novozymes feed enzyme alliance has brought groundbreaking products to market in the following classes:

Phytase enzymes
Phosphorus is essential for animal metabolism and therefore plays a key role in livestock growth and reproduction. Phytic acid is the principal storage form of phosphorus in cereals and oilseed meals – the most common feedstocks – and in this form it is mostly inaccessible to swine and poultry.  As a result, inorganic phosphates must be added to animal feed to meet phosphorus requirements, leading to increased costs. Adding Novozymes phytase enzymes to feed enables poultry and swine to access and digest the phytate bound phosphorus already present in the plants. This leads both to a reduction in feed costs and in levels of phosphorous excreted, which in turn lessens the environmental impact of livestock production.

Protease enzymes
Amino acids, the constituent elements of protein, are essential for muscle growth in animals, and – after energy – protein is the most costly part of animal feed. By enhancing the digestibility and utilization of amino acids from all protein sources, proteases from Novozymes help to reduce the total protein content required in feed, thereby reducing feedstock costs. They also help reduce levels of nitrogen excreted, reducing the impact of livestock production on the environment.

Carbohydrase enzymes
Cell walls are made of fiber - also known as non-starch polysaccharides - which are a source of carbohydrates. However, non-starch polysaccharides also increase viscosity in the digestive tract, limiting the digestibility of nutrients, especially in wheat and barley grains. Enzymes that degrade non-starch polysaccharides, such as xylanase and beta-glucanase, break down fiber into smaller fractions, reducing viscosity and increasing the digestibility of nutrients locked into the cell walls. Amylase further improves the digestibility of starch so as much value as possible can be extracted from the cereal grains for optimized animal performance and reduced feed costs.
