The digestibility of proteins and lipids matter in recirculating aquaculture systems to ensure maximum performance of the fish and the system. By increasing the protein digestibility, improving the right amino acid profile and increasing lipids in ORBIT feeds, proteins are used for growth instead of just being catabolised.
ORBIT feeds are formulated with a well-balanced digestible protein and digestible energy ratio (DP:DE) which is specially designed to meet the specific needs of recirculating aquaculture systems.
The right amino acid profile provided by the right combination of raw materials gives increased digestibility and high retention of the proteins.
When energy comes from the breakdown of protein, the result is undigested nitrogen, which is released as ammonia from the gills and urine. It is important to increase the utilisation of lipids as the energy source, which results in less nitrogen discharge in the water.
