The optimal combination of seed sprouting and extrusion processes reduces the energy, economic and labor costs of germination and decreases the loss of sprouted seed. To obtain sprouted seed, various pre-treatment methods were evaluated before the extrusion process. It was found that the optimal pre-treatment of seeds before sprouting is treatment with microwave radiation of 1400 W/dm3 for 20 s or 3% hydrogen peroxide for 10 min. When using such treatment methods, not only microflora suppression but also activation of the feed seed sprouting process are provided. The first sprouts appear in 12 hours. In 60 hours, the amount of sprouted seeds reaches 70-90 %. The length of sprouts at this stage of germination is optimal for further processing and is from 5 to 25 mm.

The use of local raw materials in the mixed fodder formulations for broiler chickens, including non-traditional raw materials, allows to expand the range of manufactured feeds possessing high nutritional properties and biological value. In order to improve the quality and to reduce the production costs of the mixed fodder due to the cheap raw materials use and the reduction of the premix use share, the mixed fodder formulation for broiler chickens was developed. The nutritional and energy value, safety of mixed fodder are determined. It is established that the nutritional and energy value of the mixed fodder with extruded mixture of non-crushed wheat, peat and cones meets the requirements of the current standard for complete feed for poultry and is obtained in accordance with the rules of the production technological process organization and supervision in the mixed fodder industry. The obtained mixed fodder with the use of non-traditional additives is non-toxic. There is no pathogenic microflora. Replacement of the expensive premix with peat, cones and introduction of non-crushed wheat grain into the mixture before extrusion helps to reduce the cost of finished products. In the production of extrudate from non-crushed wheat (98.8 %), peat (0.6 %) and cones (0.6 %), grinding and mixing with other components of the mixed fodder, the proportion of premix P5-1 decreased to 0.52%. The mixed fodder quality improvement is due to the enrichment with vitamins, essential amino acids and vegetable protein by adding cones and peat.

Development of modern feed production imposes the need for energy-resource-saving technologies that increase the nutritional value of finished feed. The extrusion of grain and other components included in the animal feed formulation is an additional resource of high-energy feed. Of practical interest is the production of extruded feed using protein-vitamin coagulate from green mass sap. Extrusion technology enables production of a high-quality product, provides bacterial purity of feed and ensures its high safety, which determines the effective use of extrudate in rations. Studies have been carried out to improve the technology for producing extrudates from a mixture of wheat grain and protein-vitamin coagulate obtained from alfalfa sap. An experimental production line for producing extrudates using protein-vitamin coagulate is proposed. The optimal ratio of grain and protein-vitamin coagulate was determined based on the analysis of the composition and energy value of the extrudate. It is noted that the protein content in extrudates from a mixture of wheat grain and protein-vitamin coagulate is 9%–24% higher than that in extruded wheat. The metabolizable energy in such feed is 1.4–3.1% higher than that in extruded wheat. The proposed technology for extrudate production using protein-vitamin coagulate provides feed and feed components with high protein content and metabolic energy. The mixture of wheat grain and 12% protein-vitamin coagulate is found to be optimal. Extrudates obtained on the basis of the optimal ratio of components contain 17.69% protein and 14.61 MJ/kg of metabolizable energy.
