Abstract

Using enzyme fractions isolated from the pyloric caeca of farmed Atlantic cod, the in vitro degree of protein hydrolysis (DH) of numerous conventional and novel feed ingredients were measured by a closed-system pH-Stat assay. Regression equations describing the relationship between in vivo apparent protein digestibility (ADC) and in vitro protein DH were used to predict in vitro protein ADC. The equations resulted in good correlation (
