Determination of the threonine requirement for maintenance in Atlantic salmon (Salmo salar L.) fry with the diet dilution procedure
A study was conducted to evaluate the threonine (Thr) requirement for maintenance in Atlantic salmon using the diet dilution procedure (DDP). Fourteen groups of 60 salmon fry [1.46 g initial body weight (BW)] were fed on seven semi-purified diets containing graded levels of N (3-64 g kg(-1) dry matt...
