    In cattle breeding, the generation-to-generation characteristics of stable transmission to generations belonging to the same species and the structural structures of the cattle breed are discussed, and the formation of independent types in the climatic and pasture conditions of each region is studied.

The article provides information on effective methods of using purebred cattle, taking into account the breed and age of dairy cows, determining lactation periods, and producing maximum milk in order to produce high-quality milk products in cattle breeding.

The ways of intensive rearing influence on the meat productivity of the stunted young cattle of Simmental breed and the ways of rational using of genetic possibilities of the animals of the studied groups for increasing the production of high-quality beef and
increasing the profitability of the branch have been revealed. The experimental data replenish the scientific information and substantiate the comprehensive research on improving the Simmental breed and give practical recommendations for organizing the rearing of young animals, taking into account the weight and age specificity. The determined biological laws of growth and development of the tissues supplement and expand the views on the quantitative and qualitative estimation of the meat productivity of young animals.

Definition and value of feeding factor of mulberry-trees leaves by caterpillars influencing the development and productivity of silk worms is lightened in the article

In the article, the revitalization and maintenance of mulberry silkworm breeds and hybrid seeds at different temperatures and humidity has been proven on a scientific basis, theoretically, data has been obtained and analyzed in depth. The goal is to prepare silkworm eggs, to improve the productivity and technological properties of cocoons based on the adaptation of silkworms to the rapidly changing natural climatic conditions of Uzbekistan. In the maintenance of mulberry silkworm breeds and hybrids adapted to the conditions of Uzbekistan, effective scientific solutions for the care of new breeds and hybrids in sharply changing temperature and humidity have been determined by basing the effective agrotechnology of silkworm feeding on the influence of the temperature of the mulberry silkworm, relative air humidity, the amount of food on the biological, cocoon productivity and technological properties of the silkworm.
