sincer nu stiu ce sa mai cred, sunt atat de multe pareri pro si contra incat ma gandesc sa trec la mamaliga clasica, fara betaine robin roade, glmeuri si alte din astea greu de pronuntat si de cumparat.
Betaine, L-alanine, L-glutamic acid, L-arginine, glycine and inosine are known as dietary feeding attractants for many fish species. However, these additives also have very important physiological functions within the animal body. For example, betaine given singly or mixed with other attractants has been found to have a positive effect on fish growth and survival rate. Betaine is also a very important substance for methyl donation and osmoregulation during the transfer of salmon and trout from freshwater to seawater. Similarly, L-alanine and L-glutamic acid can readily enter the citric acid cycle and be used for energy supply in fish and fish larvae. Moreover, L-arginine is an essential amino acid for fish, glycine is an important constituent of collagen and elastin, and inosine is a nucleoside and has vitamin activity in many fish species.
Betaine and certain free amino acids give the opportunity to fish nutritionists in preparing more palatable feed for fish during the different growth stages. As a mixture of attractive substances, they can usually beneficially affect both feed consumption and fish growth.
