Prosaf® is a premium yeast extract obtained from the primary culture of a proprietary Saccharomyces cerevisiae baker’s yeast strain. The yeast cells are autolyzed before centrifugation to separate the yeast extract from the yeast cell wall. The strain selection and standardization process guarantee the high quality and batch-to-batch consistency of Prosaf®.


  • Enhances feed preference and intake of shrimp fed with low-fishmeal diet
  • Improves dietary protein and essential amino acids digestibility
  • Increases growth performance and feed efficiency
  • Support natural defenses of shrimp fed with low-fishmeal diet

Mode of action

With a high protein content (› 63%), mainly consisting of free amino acids, small size peptides, glutamic acids and nucleotides from yeast cell content, Prosaf® increases shrimp feed attractability and palatability by releasing small soluble molecules in the water. Thanks to its complete and highly bioavailable amino acids profile, Prosaf® improves the protein digestibility of low-fishmeal diets. Thus improving feed efficiency and growth performance. Prosaf® has also proven ability to improve the overall health status of shrimp.
