The use of acids was tested in tropical warm water species, like tilapia (Ramietal.,2005) and cat fish (Owen et al.2006).
Aim of the trial
This study was conducted to investigate the effect of a well balanced combination of organic acids (buffered mixture of formic and propionic acids) based on a sequential release medium (Biotronic® SE) in cat fish feed to improve the growth performance. Different inclusion levels were tested to determine best dosage for the application of the product.
