| Popis: | The main goal of the current study was to investigate the effects of low protein diets along with fishmeal replacement by plant protein in rainbow trout diet. In the current study, three protein levels (32, 36 and 40%) and three fishmeal levels (20, 40 and 60%) were tested in rainbow trout. Amino acid content of the diets were balanced by addition of essential amino acids. This led to nine experimental diets and three replicates for each treatment. The results showed that growth parameters were influenced by protein level (p0.05). Maximum growth was observed in fish fed diet containing 36% protein and 40% fishmeal. Both protein level and fishmeal replacement affected TAN excretion in rainbow trout (p |
