Yeast extract targeted at low-fishmeal fish and shrimp diets
Our top performing story on social media last month was the report about Lesaffre’s animal nutrition business unit, Phileo, launching a high protein yeast extract product at Aqua 2018 in Montpellier at the end of August.
The Lille, France headquartered company said ProSaf is aimed at improving protein digestibility, feed intake and growth performance in low-fishmeal shrimp and fish diets, rather than 1 to 1 replacement of fishmeal in the diet.
Free amino acids, glutamic acid and nucleotides from yeast cell content increases shrimp feed attractability and palatability, when those small soluble molecules are released into the water, the product also improves primary defenses in shrimp through increasing the total hemocyte count and phenoloxidase activity, said the company
The pressure to reduce fishmeal usage in aqua feeds is one of the limiting factors for growth in the aquaculture industry, but there are technical challenges associated with low fish-meal diets, said Otavio Serino Castro, global species manager/aquaculture, Phileo Lesaffre.
He told us that inclusion rates with ProSaf range from 0.5 to 2.5% of the complete shrimp feed, making it cost effective: “This is one point of differentiation for us.”
