In recent years, the world population of dairy goats has grown. Advanced farms have observed a significant increase in the productivity of dairy goats up to 1600 kg of milk on average in the herd. This is ensured by the development of industrial technology, new methods and techniques of feeding, herd reproduction and rearing. Robotized complexes for feed preparation and distribution, etc. are being introduced on farms. The range of scientific achievements in dairy goat breeding includes the technology of prolonged lactation from 600 to 1500 days without tupping.
