Abstract
Until 2020, Russia has a state program for the development of agriculture, therefore the organization of livestock complexes is actively initiated and supported. In this regard, the arises the question of inexpensive feed for farm animals availability. More recently, the demand for protein feed products largely was covered by imports. However, at present, there is an economically determined decrease in demand for imported goods, which naturally increases interest in domestic analogs of protein feed products. One of these products is fodder yeast. Currently, this kind of feedstuffs was undeservedly forgotten and most production facilities in Russia curtailed. In the production of fodder yeast, for example from post-alcohol stillage, the profitability of grain processing is significantly increased. In addition, the processing of carbohydrate-containing wastes from grain processing enterprises reduces the negative impact on the environment. According to the results of the studies, the most effective protein producing strains and nutrient media were selected based on secondary raw materials from grain processing, as well as the optimal mode and conditions for their cultivation. It was found that the most effective strain was Rhodosporidium diobovatum 115 using post-alcohol stillage as a nutrient medium.
