SPECIAL STORY 54 FEED & ADDITIVE MAGAZINE August 2023 INCREASING EFFICIENCY OF RAW MATERIALS Thanks to the 20-year alliance between dsm-firmenich and Novozymes, we enable the animal industry to further optimize nutrition and ensure we can achieve more with less. Our phytase RONOZYME® HiPhos can take feed phytase to the next level. Less inorganic phosphorous needs to be added to the diet, resulting in substantial savings on feed costs. The reduction of the amount of finite rock phosphate used in diets leads to a decrease in phosphorus excretion to the environment and less eutrophication of freshwaters. The supplementation of diets with HiPhorius™ can increase digestibility of phosphorus up to 19%, 35% and 22% in seabass, tilapia and rainbow trout respectively, when compared to diets including inorganic phosphorus. Our RONOZYME® ProAct is dsm-firmenich best-in-class feed protease which increases protein digestion across a range of feed ingredients, thereby reducing feed costs. RONOZYME® ProAct optimizes amino acids digestion, reduces costs, mitigates effects of feed protein variability, reduces adverse effects of anti-nutritional factors as well as improves gastrointestinal functionality. RONOZYME® ProAct can increase protein digestibility in tilapia up to 10%. When compared to shrimp diets with reference levels of crude protein or fish meal standard inclusion levels, the use of RONOZYME® ProAct can maintain animal performance when either crude protein or fish meal content is decreased. SUPPORTING EMISSIONS REDUCTION Intensive pond aquaculture produces large amounts of organic waste, most of which settles at the pond bottom, negatively affecting water quality, health and growth performance. The oxidation of this organic material depletes oxygen levels and forms toxic metabolites such as hydrogen sulfide and nitrogen wastes. Probiotics can help in improving water quality and maximize survival and growth, reducing at the same time the need for lengthy and often expensive manual organic sediment removal between production cycles. Our AquaStar® is the most complete aquaculture probiotics range on the market as bioremediation tools to improve pond management and increase productivity. The multi-species approach builds on synergies and complementary modes of action between different bacterial species, and ensures users are provided with maximum benefits. AquaStar® drives enzymatic breakdown of organic matter, reduces N-metabolites and toxic hydrogen sulfide. Thanks to its quorum quenching properties, AquaStar® is ideal for pathogen and biofilm control. Field trials in shrimp have demonstrated that AquaStar® can reduce ammonia in the water column by 60% and nitrite by 25%, improving survival by 18%. Digestibility of phytate-P can be improved by using enzyme technology, such as phytase, to break down phytic acid, providing economic and environmental benefits for both the feed producers and farmers. For example, our phytase HiPhorius™ improves phosphorus digestibility and can significantly reduce phosphorus emission in the water by up to 83% in sea bream, 80% in tilapia and 77% in sea bass.
