Animal feed ingredients
& feed enzymes
 Animal feed comprises 5 main nutrient groups
 1. Protein                        Soybean seed/meal, fishmeal…
 2. Carbohydrates                  Cereals (corn, wheat, barley…)
 3. Other energy sources           Oils or fats
 4. Minerals                       Mined resource
 5. Micronutrients (vitamins…)     Various

 Feed enzymes comprises 3 key groups improving the digestion of nutrients
 Proteases:       to improve protein digestibility by 3-6%
                  and reduce the nitrogen output by 1/3
 Carbohydrases:   Xylanase et beta-Glucanase are the main enzymes to
                  increase Energy utilization from grains by 3 to 8%
 Phytases :       to hydrolyse plant phytate (antinutritional factor) and
                  release phosphorus, calcium, minerals, energy, a. acids

Clear Benefits of Enzymes
in Animal Nutrition
Besides usual feed costs savings from feed reformulation with DIF values
(Digestibility Improvement Factor for Carbohydrase) or matrix values (for
phytase and protease), the use of feed enzymes significantly reduces the
impact of animal production on the emission of Green House Gas

Advantages of using feed enzymes:
       – Reducing consumption of scares resources
           e.g. phosphorus, protein
       – Reducing emissions of phosphorus and nitrogen
           from manure into water systems and air
       – Reducing energy consumption and sulphur emission
           from using biotechnology vs other technologies
       – Releasing millions of hectares of arable land

Raw material savings and uses


                                                 The environmental advantages of using new
                       Saved       Used          RONOZYME® HiPhos (M) over MCP are :

                                                 - reduced consumption of a scarce resource of
                                                 rock phosphate from MCP production

                                                 - reduced algae bloom by reducing phosphorus
                                                 emissions from manure into lakes and rivers

                                                 - reduced energy consumption and CO2
                                                 emissions because RONOZYME® HiPhos (M)
            9.0 kg                               production is 50 times less energy intensive
          Phosphorus                             than MCP production



                                     0.020 kg
                                    HiPhos (M)
All data are per one ton of feed
Feed enzymes for sustainable animal nutrition
Feed enzymes use play key roles in global resource management and global
environmental impact of animal protein production as


• We need more and more grains and vegetable protein to feed the planet

• Raw material prices go up alongside the demand and limited arable lands,

• Mineral phosphate is a limited resource in both quality and quantity, so…

• Reduction of Phosphorus and Nitrogen emission and soil contamination is a

   must

Our mission at DSM is to create brighter lives for people today and generations
to come.

• Are the enzyme effects additive ?
   – Complex problem to resolve
        • What enzymes are being considered, at what dose
        • What nutrients are affected
        • What raw materials are being used at what level (%)

• Are they additive (a + b = ab)

• There is no additivity (a + b = a)

• Additive but at lower level (a + b = ab)

• Additively may be synergistic (a + b = AB)

• May have negative effect (a + b =    ab)

Consideration for nutrient enhancement when
multiple feed enzymes are used
 • Age/animal species and breed

 • Substrates available from feed raw materials for the enzymes to act

 • Physical characteristics of enzymes (e.g. particle size distribution,
   thermostability, pelleting stability etc) and processing/storage
   conditions

 • First match nutrient enhancement to the primary effect of each enzyme
   E.g. phytase for minerals, carbohydrases for energy and proteases for
   protein/AA

 • Taking all of the above come to the final nutrient enhancement
   attributed to the enzymes

Micronutrients (vitamins…) Various Feed enzymes comprises 3 key groups improving the digestion of nutrients Proteases: to improve protein digestibility by 3-6% and reduce the nitrogen output by 1/3 Carbohydrases: Xylanase et beta-Glucanase are the main enzymes to increase Energy utilization from grains by 3 to 8% Phytases : to hydrolyse plant phytate (antinutritional factor) and release phosphorus, calcium, minerals, energy, a. acids Page

    Clear Benefits ofEnzymes in Animal Nutrition Besides usual feed costs savings from feed reformulation with DIF values (Digestibility Improvement Factor for Carbohydrase) or matrix values (for phytase and protease), the use of feed enzymes significantly reduces the impact of animal production on the emission of Green House Gas Advantages of using feed enzymes: – Reducing consumption of scares resources e.g. phosphorus, protein – Reducing emissions of phosphorus and nitrogen from manure into water systems and air – Reducing energy consumption and sulphur emission from using biotechnology vs other technologies – Releasing millions of hectares of arable land Page

    Enzyme Combinations • Arethe enzyme effects additive ? – Complex problem to resolve • What enzymes are being considered, at what dose • What nutrients are affected • What raw materials are being used at what level (%) • Are they additive (a + b = ab) • There is no additivity (a + b = a) • Additive but at lower level (a + b = ab) • Additively may be synergistic (a + b = AB) • May have negative effect (a + b = ab) Page After Kleyn 2010

    Consideration for nutrientenhancement when multiple feed enzymes are used • Age/animal species and breed • Substrates available from feed raw materials for the enzymes to act • Physical characteristics of enzymes (e.g. particle size distribution, thermostability, pelleting stability etc) and processing/storage conditions • First match nutrient enhancement to the primary effect of each enzyme E.g. phytase for minerals, carbohydrases for energy and proteases for protein/AA • Taking all of the above come to the final nutrient enhancement attributed to the enzymes Page
