Influence of Silkworm Feeding Area and Nutrient Content on Cocoon Yield and Technological Properties

For instance, when a farm doesn't have special worm-nurseries and mulberry plantations, this can influence negatively on silkworm rearing process. Nowadays, some silkworm breeders of particular farms are rearing the silkworm and producing cocoon in their own houses. The rooms for silkworm are small, even though the rooms are intended for a half box worms, instead of this, one box or one and half box worms are reared in these rooms. Accordingly, the feed is not provided to the worms in the norm that leads to different sizes of larva, decrease in their survivability, causes various diseases, decreasing of cocoon productivity and variety grade. In order to solve these problems positively, it is intended to carry out research works on the determination of the amount of silkworm according to ages of silkworm in feeding area and feeding dates, changes in feed amount given on this base, preventing diseases and eventually providing variety grade and productivity in accordance with fixed requirements, and to give appropriate suggestions for production. Therefore, when silkworm passes from age to age (instar), its body enlarges physiologically, accordingly it requires wider feeding area for obtaining normal nutrition. The provision of proper and wide feeding area is of crucial task of today in the cocoon production. If this practice is not performed properly, mulberry leaves are not provided to worms enough due to the imbalance of feeding area resulting improper feeding of silkworms and their difference sizes.
