Evaluation of barothermally processed casein as a component of trout starters. II. The effect on fish growth

Abstract

Six experimental trout starters containing 8-40% of processed casein were tested. The experiment lasted 50 days. Rainbow trout fry of average individual body weight 1.5-1.7 g was used. The best results were obtained with the starter containing 32% of caseinate – final fish body weight was 18.07 g/ind., feed conversion rate 0.85, PER – 2.32, and aNPU – 33.50.
