Effect of pancreas disease caused by SAV 2 on protein and fat digestion in Atlantic salmon
Abstract Salmonid alphavirus (SAV) causes pancreas disease (PD) in farmed Atlantic salmon ( Salmo salar L.), and exocrine pancreas tissue is a primary target of the virus. Digestive enzymes secreted by the exocrine pancreas break down macromolecules in feed into smaller molecules that can be absorbe...
