The optimum dietary indispensable amino acid pattern for growing Atlantic salmon (Salmo salar L.) fry.
To determine the optimum indispensable (I) amino acid (AA) balance in Atlantic salmon (Salmo salar L.) fry, a single protocol established for the pig was adapted. The balance was calculated from the reduction in N gain after replacing about 45% of a single IAA by a mixture of dispensable AA in isoni...
