New research explores 'triple benefit' of adding phytase to tilapia feed

Two recent studies have demonstrated that adding phytase to tilapia diets offers producers a threefold benefit of improvements across nutrient digestibility and retention, as well as mineral status and feed conversion rates. “Strategies for reducing feed costs – which can account for 60% of total production expenditure – and minimizing ecological damage are becoming increasingly important in the fish industry. The effect of phytase represents benefits for both: the improved mineral status spares 0.25% of available phosphorus, reducing production costs, whilst the increased retention of nutrients results in lower levels of water pollution.” The studies will be presented AB Vista at this month’s LACQUA.

New research explores 'triple benefit' of adding phytase to tilapia feed

October 11, 2018

The trials, conducted in partnership with the Federal University of Parana in Brazil, showed that the addition of 2,000 FTU/kg of Quantum Blue phytase to tilapia diets resulted in improvements across nutrient digestibility and retention, as well as mineral status and feed conversion rates.

The studies also indicated that such performance benefits impacted positively on feed costs and environmental welfare. 

“Strategies for reducing feed costs – which can account for 60% of total production expenditure – and minimizing ecological damage are becoming increasingly important in the fish industry," stated Alexandre Barbosa de Brito, AB Vista LAM Technical Manager. "The effect of phytase represents benefits for both: the improved mineral status spares 0.25% of available phosphorus, reducing production costs, whilst the increased retention of nutrients results in lower levels of water pollution.” 

“Quantum Blue breaks down the phytate found in plant-based ingredients, releasing phosphorus that otherwise would not be available," stated Mr. deBrito. "In addition, calcium ions are released, which are usually linked to the phytate molecule – and therefore are unavailable for absorption.

“In addition, it was demonstrated throughout these recent trials that phytate affects endogenous secretions by the animal, and reduces the digestibility of various nutrients in the intestinal lumen of the animals, which can be attenuated by the addition of phytase.” 

The research will be presented during the 4pm session on October 25th at LACQUA, taking place in Colombia from October 23rd to 26th.
