A feeding study was conducted to elucidate the role of two different fibers, cellulose and agar, and mixture of the two fibers on fecal mucinase activity in rats. Fiber-free basal control diet was mixed with either 15% cellulose, 15% agar or half cellulose (7.5%) and half agar (7.5%). These diets were fed for 5 weeks to groups of 6 male Sprague-Dawley rats. Mucinase activity was assayed in fresh rat feces. Body weight gain of rats fed different diet groups did not show significant difference (p>0.05). Specific and total mucinase activity was highest in rats fed fiber-free control diet and 15% agar diet, intermediate in rats fed the fiber mixture group and lowest in rats fed 15% cellulose diet. The differences among the three groups were significant (p<0.05).
