Abstract

The present experiments were carried out to investigate the role of ceca of chickens in the digestion of nutrients, using 4-month-old cockerels of single comb White Leghorn. The results obtained were summarized as follows. 1) There was no significant difference in the digestibility of nutrients between ceca of ligated and non-ligated chickens when they were fed on various diets, such as a conventional diet, conventional diet added 20% of ground rice hull and conventional diet added 10-20% of ground ladino clover hay. 2) The digestibility of nutrients was significantly higher in chickens fed the heated soybean meal diet than that of chickens fed the diet containing raw soybean meal, and no significant difference was observed in the digestibility of nutrients between ceca of ligated and non-ligated chickens. 3) When the chickens were given the conventional diet and conventional diet added 10% of pulp, no obvious difference in the digestibility of nutrients was observed between ceca of removed and non-removed chickens. 4) The digestibility of nutrients in the chickens severed the cecal main vessels or neurectomized of ceca was similar to that of the control chickens when they were fed on the conventional diet.
