The efficiency of beef production in the donbass region according to organic principles using fodder pumpkins

The Ministry of Agriculture of the Russian Federation has set a task to increase the production of organic livestock products at least 5 times in the coming years. Largely, this applies to beef production. To solve this problem bulls can be used, which cultivation is not profitable today. When producing beef according to organic principles, the price of its sale should increase significantly, and the production itself will acquire economic meaning. To achieve such a result, it is necessary to develop a new technology for growing bulls, which will ensure their sufficiently high growth rate and will comply with the provisions of the law on the production of organic products. Due to our own research, we have proposed an organic system for growing bull calves using a two-stage technology, which is based on the introduction of crushed fodder pumpkin into the composition of fully mixed rations of young animals. The possibility of increasing the live weight of bulls by 21.1 kg (6.2%) has been reliably proven. The level of productive use by bulls of a full-fledged silage-concentrate mixture with the introduction of pumpkin into its composition is as high as possible (98-98.3%), which is 6-7.4 absolute percent more than peers who consume only silage-concentrate rations. The replacement of 30-50% of corn silage with pumpkin in the bulk part of the rations of bulls provides an increase in the coefficient of transformation of the total energy of the technological process of beef production into energy of weight gain of young animals from 3.01 to 3.11%, and the level of profitability of organic beef production by 17%.
