The use of substandard grain in the technology of compound feed of increased nutritional value

Abstract

The article discusses the complex processing of substandard grain and by-products of processing agricultural raw materials in the technology of obtaining a combined feed with increased nutritional value.A method for processing feed with polysteam lactic acid ferment based on whole-ground soy flour and wastes from processing soybeans in the presence of 0.5% lactose solution is proposed. The optimal modes of feed biofermentationhave been established: pH – 5.2, medium temperature - 25°C. There was an increase in the finished product of reducing substances by 23.3%, crude protein up to 12.8%.The proposed method in the production of compound feed allows you to process substandard wheat grain, obtain a protein mass, dispose of production waste - soybean meal, thus eliminating sources of environmental pollution.
