ОСНОВЫ ТЕХНОЛОГИИ ПРИГОТОВЛЕНИЯ КОНЦЕНТРАТОВ ИЗ РАСТИТЕЛЬНОГО БЕЛКА ДЛЯ КОМБИКОРМОВ

Abstract

Legumes are a great reserve of high-grade protein feed for pig production, creating a solid base for the production of import-substituting additives that provide a balanced feeding of animals and increase the competitiveness of the industry. It is recommended to extend a science-based use of vegetable protein, especially legumes, using special technology of processing of raw materials for inactivation of anti-nutritional substances. It was established that the technological processing of soy and lupine (micronizing, flaking, extrusion) improves the quality characteristics of the feed, which is beneficial to absorption of nutrients. Studies have shown that the use of micronized, extruded and autoclaved soy and shelled extruded lupine reduces the cost of the balancing concentrate without compromising its quality. At the same time, the productivity of animals does not decrease, the intestinal microbiocenosis does not go beyond the norm, and the metabolism remains at a high level. This has been shown to improve nutrient absorption. The optimal mode of moisture-thermal treatment of soybeans by the micronization method was determined: soybean moistening up to 19%, its IR irradiation for 60 s at a temperature of 130 ° C, followed by tempering (exposure) at 90 ° C for 15 minutes. A technological scheme for the manufacture of balancing concentrates is given. These concentrates are cheaper than fishmeal, their use allows you to reduce the cost of feed, get additional income and, as a result, contributes to the high profitability of the pig industry.The composition of high-grade protein concentrates are maked. The productivity of animals is not decreased bowel microbiocenosis did not go beyond the limits of Maximum Permissible Concentrations, digestion of nutrients was high enough. It is shown that it is beneficial to the assimilation of nutrients. Optimum processing mode using moisture and heat by micronization soya: soya hydration to 19%, an IR irradiation 60c for her at 130 ° C with subsequent tempering (extract) at 90 ° C for 15 minutes is defined. Technological scheme for producing of additives is shown. Are developed highprotien concentrates alternatively to import analogues and forages of an animal origin for mixed fodders. Industrial tests of mixed fodders with different developed concentrates in the conditions of pig-breeding complexes on different stages was fulfill. Growth of pigs are registrated.
