New generation of phytase improves growth performance in tilapia Daniel Arana, Huvepharma
According to the FAO, aquaculture has projected growth to produce nearly 109 million metric tonnes by 2030. The global trend to be more sustainable is paramount in the aquaculture industry and is leading to better use and optimization of all the ingredients often used in the feed industry. It is known that phytase enzymes maximize the phosphorous (P) availability in plant-based ingredients
and also afford cost-effective feeds by optimizing the animal’s use of the nutrients in raw materials. This is also valid for omnivorous fish species produced and consumed around the world. Tilapia is the second most cultivated fish in the world, just after carp and ahead of salmon. Production is growing at an estimated 7% annually over the last decade. This growth demands more resources
