Free amino acids

To improved performance in aquaculture

Kera Aqua

A unique mix of 17 natural free amino acids.

The origin of BCF Life Sciences products is a renewable bio-resource raw material. This procurement approach is part of a sustainable circular economy. From a single source, poultry feather, Amino Acids are extracted from keratin, the unique matrix composing the feathers.

This sustainable protein source contributes significantly to the reduction of marine inputs in formulations. In addition, by helping to improve food efficiency, it helps to preserve the resource and limit the impact on water quality.

Our products are composed of 17 amino acids mainly in free form (aspartic acid, threonine, serine, glutamic acid, proline, glycine, alanine, valine, cystine, methionine, isoleucine, leucine, tyrosine, phenylalanine, lysine, histidine, arginine).

The low molecular weight of these amino acids gives them a level of digestibility close to 100% and rapid assimilation by young organisms. In addition, these small molecules are easily detected by shrimp chemoreceptors and strongly stimulate food intake. The benefits result in a significant improvement in zootechnical performance.
