This experiment was conducted to investigate the feeding value of silk-worm excreta in the diet of growing chickens. Forty-fire day old 180 White Leghorn male chicks were divided into 3 treatments imposed, and each group involved 3 replications of 20 chicks each. The experimental diets were contained 0%, 5%, and 10% of silk-worm excreta, respectively. The wire-floored batteries were used throughout the period of feeding trial. Following the four weeks feeding trial period, 4 chicks with artificial anus were kept in individual metabolism cages to determine the digestibility of tue experimental diets. Under these conditions, body weight gain, feed intake, feed efficiency, and the digestibility were observed. The experimental results obtained were as follow: (1) The body weight gain was slightly decreased in the 5% lot and the 10% lot, respectively, but there was no significant difference between treatments. (2.) In feed intake, there was no significant difference between treatments, but birds fed higher silk-worm excreta consumed little higher amount of feed. (3) In feed efficiency, no significant difference was observed between treatments, however, birds fed higher silk-worm excreta diet showed slightly over feed efficiency. (4) The digestibility was also slightly decreased when the sick-worn excreta was fed, but no significant difference was found. As a result of these experiments, it was found that the diet contains of sills-worm excreta can be satisfactorily used for the growing chickens.
