Abstract
A pH-stat in vitro assay method using enzyme fraction from fish pylori c ceca was developed for estimating protein digestibility in salmonid diets. The data obtained by pH-stat method were compared with those ob tained by pH-shift methods and with in vivo digestibility in fish. Res ults indicated that the pH-stat method better predicts the range of pr otein digestibility of the samples studied than pH-shift methods. The method has potential as an accurate way to estimate the digestibility and biological value of alternate protein sources for salmonid feeds.
