Growth study was made on 96 male rats with treatments (15g diet, 03.g N/day): wheat bran (B) 5%, 2.1% neutral (NDF) and acid (ADF) detergent fibers, pectin (P), cellulose (C) and no‐fiber (No‐F) at two levels of energy (57 and 67 Kcal/day) for 4 wk and extended period. II. until 8 wk. In Period II. B and NDF diet resulted in significantly higher (P < 0.05) weight gain and protein efficiency ratio than No‐F, in spite of increased fecal N excretion. Urinary N excretion was the most for NoF and the biological value the least (P < 0.05). Data suggest, at marginal intake of protein and energy closer to the requirement, dietary fiber has a role in the rat's growth and improved utilization of absorbed N.
