Conducting scientific experiments with selective breeding materials of the silkworm. Based on experiments and observations by scientists, it has been established that the silkworms from the breeding materials are currently in the third, fourth, and fifth instar stages. Staff members ежедневно determine the biological and production indicators of families of breeding lines, breeds, and hybrids of silkworms and record them in working journals. In order to increase silkworm productivity and improve cocoon quality, the required rearing standards are being followed: mulberry leaves are chopped and fed to the silkworms. The silkworm families are in good physiological condition, and the environmental conditions within the rearing facility have been adjusted to comply with established standards.
