THE RESEARCHES OF RECEIVING A PELLETED FEED FOR POULTRYBASED ON BINARY COMPOSITIONS

Poultry farming in the Russian Federation is a dynamically and successfully evolving branch of agricultural production at the present stage of national economic development. The question of effective and efficient feeding in aviculture has always been a very acute problem. In the struc-ture of the final cost of products formation feeding stuffs reach 75% according to various es-timations. The most expensive in the production of feed mixtures are suchprotein components of the food ration as fish meal and bone tankage, soy and sunflower meal, protein additives and concentrates. However, as the study shows, the possibilities of such high-protein cultures, as soybean are not fully in use for feed production. Along with soybean and its processed prod-ucts, it is also possible to use food waste products from the meat and fish industry, in respect that the waste processing of poultry is more than 30% of the bird’s carcase weight. These com-ponents of the feedstuff are also quite valuable, because they are rich in high-grade protein and able to meet the daily demand of poultry in amino acids. Until now, it has not been paid enough attention to applied researches, related to obtaining binary soy-meat and bone meal, soy-fishbone meal, soy-herb and soy-luminaria feed mixtures. In such combinations, the mois-ture contained in the raw material is average and, therefore, it is possible, at least twice, to re-duce the energy costs for its removal during drying. At the same time, as a result of the analyti-cal review, it was revealed a contradiction between the desire and endeavor of producers to improve the efficiency of poultry production by finding rational methods of preparation, appli-cation of modern technologies and improved technical means in the preparation of feed pellets based on binary compositions on the one hand and a known level of scientific knowledge about the laws of obtaining meat-bone, fish-bone or vegetable-grass pastes, the processes of averaging of moisture in the binary compositions and mechanisms of formation of the final product, namely, seals, molding pellets with a low crumbling and their subsequent drying on the other hand. In this connection, studies aimed at improving lines for production of feed products in the form of protein-mineral and protein-vitamin compositions using soy component are relevant and have important economic significance. The presence of this problem is also due to the lack, at modern stage of development, of special equipment and technologies, as well as scientifical-ly-based data for the design and construction. The paper proposes the design of a promising device ¬- a press granulator designed for the preparation of granulated feed for poultry on the basis of soy-meat and bone compositions and the results of experimental studies.
