BelTA press center spoke about new technologies in agriculture

February 20, MINSK. Nikolay Bakach, Deputy DIRECTOR General for Research of the Republican Unitary Enterprise "Scientific and Practical Center for Agricultural Mechanization of the National Academy of Sciences of Belarus" spoke about the new developments of Belarusian scientists for agriculture, BelTA has learned.

"The efficiency of the livestock industry is 60% dependent on the level of feeding and the quality of the main types of feed, so the feed must meet the needs of the animals. If we consider the process of harvesting haylage and hay, then one of the systematic operations is their raking. Thus, the scientists of our SPC, together with one of companies have developed special rakes, the design feature of which is to ensure minimal contact of the feed with the soil. This prevents dust, earth and stones from getting into the feed. This unit provides a capacity of up to 11 hectares per hour, "said Nikolai Bakach.

In addition, to speed up the process of drying grasses, as well as harvesting hay and haylage in rolls and bales, a device for re-drying cut grasses has been developed. it provides productivity up to 4 hectares per hour. The use of this device, according to the Deputy General Director, makes it possible to speed up the process of drying cut grass by 15-20% compared to traditional methods of forage harvesting, and also to better preserve their nutritional value.

Nikolai Bakach also noted that, according to research, the potential of a cow's MILK productivity is laid down at the stage of calf rearing, and more than 60% of the efficiency of this process depends on the conditions of their keeping and feeding.

“It has been established that from the second week of a calf’s life, in order to form its digestive system, it is necessary to start giving special compound feeds and additives in addition to milk. Thus, technologies and a set of equipment were developed for the production of easily digestible concentrates based on local grain raw materials for animal milk. The basis for the preparation of this feed is the idea of ​​processing a mixture of grain components by extruding and mixing with dry mineral additives.Since the process of extruding the feed itself is quite energy intensive, the technology of extruding preheated grain up to 80 degrees was used to reduce energy costs, where an induction heating system by means of a magnetic field is used" , - explained the deputy general director.

According to him, as tests have shown, the cost of producing this concentrate in this way is 15-20% lower. At the same time, feeding calves with milk concentrate increases their productivity by 6.5%, and reduces the consumption of whole milk.
