Abstract

The present research proposal aims to assess digestibility and retention of key nutrients for the growout of farmed shrimp: amino acids and phosphorus. Trials will consist in practical formulation of diets including a target ingredient at different levels (experiment 1: soybean meal -46% CP; amino acid digestibility) or with different ingredients and additives (experiment 2 and 3: supplementation of inorganic phosphorus or exogenous enzyme phytase at low P diets). Amino acid body deposition will be checked at varied dietary inclusion of soybean meal with digestibility and stable isotopes (C and N) feed-body content relationship as potential tools. Different sources of inorganic phosphorus or the phytase supplementation will be assessed in plant based diets in comparison to a P poor control diet. Outputs may assist larger scale trials. A differential for future shrimp feeds in short term will be digestibility data available into farming systems. Present proposal include research tasks suggested by Brazilian farmer´s associations.
