| Abstract;The aim of this study was to investigate the effect of dietary fiber sources on growth performance and developmental changes of the intestinal morphology in chicks. A total of 140 newly hatched male White Leghorn chicks were randomly divided into following 4 groups; ad libitum access to water and 1) a commercial grower mash diet (CP; 21%, ME; 2950 kcal/kg), 2) 5% dietary cellulose diet, 3) 5% dietary alginic acid (Sodium Salt) diet and 4) 5% dietary pectin diet groups. Until 5-week-old, feed intake was checked every 5 days, and body weight and length, weight and area in each intestinal part were measured every week. At the end of each feeding experimental period, light microscopic samples for intestinal villus height, cell area and cell mitosis in the crypt were fixed with Bouin solution. Scanning electron microscopic samples were fixed with a mix solution of glutaraldehyde and paraformaldehyde. Compared with the intact controls, dietary cellulose diet did not induce a specific alteration in feed intake, body weight gross and micro anatomical changes in the intestine except for the villus surface morphology showing an atrophic function. In chicks fed a dietary alginic acid diet, feed intake, body weight and gross anatomical morphology in the intestine were decreased. In chicks fed a dietary pectin diet, although body weight was decreased the intestinal villus height and cell area were increased, and villus surface morphology showed a slightly activated function. Among these dietary fiber sources, alginic acid induced the most decreased feed intake and body weight followed by pectin. On the other hand, pectin induced the most increased villus height and cell area followed by alginic acid.... (author abst.) |
