|
These experiments were executed to develop an effective rearing or collecting equipments for silkworm excreta. The rearing devices were an assembly one equipped with wheels, and its weight was reduced so that the convenience was improved. In the amount of collecting silkworm according to the size of mess, the size of 7.0*7.0 mm had 36% more than the size of 5.0*5.0 mm. However, the falling silkworm had a little (0.3%) occurred for the period of rearing the 5day-silkworm. The amount of collecting silkworm excreta using the devised collecting equipment was 19.7 kg per box at the two-floored rearing boxes. In the budget of labor hour, the devised collecting equipment have reduced the labor of traditional handy work to 65% and the productivity of labor (kg/hour) was increased to 55%. The cost of production was also decreased to 35.9%.
