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...

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 isonitrogenous diets. We confirmed that the mixture of AA simulating the AA pattern of cod-meal protein and gelatine (46:3, w/w) was used with the same efficiency as cod-meal protein and gelatine. From the deletion experiment an optimum balance between the IAA was derived. Expressed relative to lysine = 100, the optimal balance was: arginine 76 (SE 0.2), histidine 28 (SE 2.2), methionine + cystine 64 (SE 1.7), phenylalanine + tyrosine 105 (SE 1.6), threonine 51 (SE 2.4), tryptophan 14 (SE 0.7), valine 59 (SE 1.7). No estimates were made for isoleucine and leucine. Expressed as g/16 g N, the optimal balance was: arginine 4.0 (SE 0.0), histidine 1.5 (SE 0.1), lysine 5.3 (SE 0.2), methionine + cystine 3.4 (SE 0.1), phenylaline + tyrosine 5.6 (SE 0.1), threonine 2.7 (SE 0.1), tryptophan 0.7 (SE 0.0), valine 3.1 (SE 0.1). This AA composition is close to that of the Atlantic salmon whole-body, but using it as an estimation of the IAA requirements may lead to an overestimation of the branched-chain AA requirements and an underestimation of aromatic and S-containing AA requirements. The results are discussed in accordance with the key assumptions associated with the model used (broken-line model, IAA efficiencies and maintenance requirements).
