This study was conducted to examine effects of dietary cellulose levels on growth and nitrogen utilization in young chicks fed equal amounts of nutrients of a 15% protein diet. Body weight gain significantly increased with an increase in dietary cellulose level until 3.5%, then decreased linearly up to an inclusion of 20% of cellulose in the diet (3.5 vs. 0, 10 or 20%, P<0.05). Feed efficiency was not influenced by dietary cellulose levels from 0 to 5%, but decreased by 10% and more dietary cellulose levels(10 vs. 1.5, 3.5 or 5%, P<0.05; 20 vs. 0, 1.5, 3.5 or 5%, P<0.05). Nitrogen(N) retention, N retention rate and retention rate of absorbed N were significantly increased by 1.5% cellulose level (P<0.05), then significantly decreased by 3.5% and more dietary cellulose levels (P<0.05). Apparent digestibility of dietary protein was not influenced by changes in dietary cellulose level. It is concluded that the highest rates of growth and N retention and retention rate are obtained by 1.5% dietary cellulose, and lowered by 3.5% and more dietary cellulose levels when protein intake is restricted to 15% crude protein in chicks.
