The trial was made to study the protein digestion in juvenile turbot during passage of digesta from stomach to rectum. Moreover, diet supplementation with the potential probiotic bacteria, <i>Vibrio proteolyticus</i>, was evaluated with regard to protein digestion. For a 3-week period, fish (25-30 g) were fed by oral intubation and received either a liquid mixture consisting of 40% nonpurified control diet and 60% water or this mixture supplemented with 10 <sup>10</sup> viable <i>V. proteolyticus</i> ml <sup>-1</sup>. Daily dry matter was 1.5% body weight. As digesta progressed from the stomach to the foregut, hindgut and rectum, the increase in apparent nitrogen digestibility was accompanied by higher... |
