Changes In The Main Production Characters Of Silkworm Hybrids During The Spring And Summer Fattening Of Silkworm Caterpillars In Hot Climate Of Uzbekistan

Abstract


In the less favorable hydrothermal and fattening conditions of a summer silkworm nursery, the average indicators of cocoons and silk weight were observed as decreasing by 22.0 and 25.0% respectively, in comparison with the favorable conditions of the Spring season. The hybrids (a 'hybrid' pertaining to biology, is an animal or organism that is the result of the crossing-breeding of two different species or varieties) have been revealed, which are more suitable to the specific conditions of summer silkworm fattening. We have started tests focused on increasing the silk productivity of the silkworm by repeated fattening using nitrogen antiseptic sources.
