The article provides a review of domestic patent information on the effectiveness of using modern probiotic feed additives in pig farming practice. The inclusion of probiotic feed additives in the diets of pigs is aimed at excluding pathogenic and opportunistic microflora from the intestinal microbiocenosis, increasing the productive action of feed and intensifying metabolic and immune processes in the organism. The introduction of probiotic feed additives into the diet of pregnant sow and suckling pigs, as well as weaned piglets, allows achieving high indicators for the safety and productivity of young animals, which is very important for the cost-effective development of production. The ability of probiotic feed additives to normalize the microflora of the gastrointestinal tract of newborn piglets provides increased resistance to mass gastrointestinal diseases, as well as increasing the safety and viability of piglets. Thus, probiotic feed additives are an important component of the modern diet of farm animals at all stages of their development. At the same time, the most popular and effective for modern pig farming are multicomponent probiotic feed additives that contain a complex of probiotic cultures with different biological effects on the organism, sorbents that often act as prebiotics, enzyme preparations and other biologically active substances that provide a positive multifunctional effect on the organism of farm animals

The article presents the results of scientific and industrial experience in identifying the effect of feed additives on the productivity and biochemical parameters of bull calves’ blood in fattening. The calves of Holstein-Friesian breed at the age of 30 days were selected as objects of research. In the diet of the bull calves of the experimental groups, we used feed additives in the main diet: probiotic feed additive “Cellobacterin+”, feed vitamin-mineral concentrate “Tetra+”, complex feed concentrate. We found that the most active weight gain is observed in the group of calves that received complex feed concentrate. In all experimental groups of bull calves, we observed a decrease in the activity of hepato-indicator enzymes and a thymol sample. Based on the data obtained, it can be concluded that the use of the complex feed concentrate containing biologically active substances and the additive “Cellobacterin+” (in comparison with the control and other experimental groups) leads to maximizing the increase in the average mass of bull calves, which is associated with the synergistic effect of biologically active substances and living microorganisms Enterococcus faecium 1 - 35. The same tendency is observed with respect to the activity of hepato-indicator enzymes - AST and ALT, which, compared with the control group, decreases by 35.6% and 28.2%, respectively

The article analyzes the patented in different countries methods of using of the ionizing radiation in processes of storing and processing of plant materials. Description of nature of the radioactive treatment and the ionizing radiation is given; examples of possible sources of the ionizing radiation are listed. Advantages and disadvantages of the radioactive treatment are shown. The patent search in databases of the WIPO was carried out. Patents, registered in countries like Korea, China, Japan, etc., were analyzed. Methods, realization of which allows sterilizing of material and increasing its storing period, and also improving its processing, were systematized. The carried out survey of the patent documentation revealed, that at the present time there is quite a number of methods of using of the ionizing radiation in storing and processing of plant materials, which can be explained by the fact, that irradiation allows to solve quite effectively a number of important tasks, such as sterilizing the material and modifying chemical substances in its content. In the article it is also shown, that, nevertheless, issues of safety and quality of irradiated products have not yet been fully resolved. In the end, the conclusion was made about the relevance of further research in this field

The article provides an overview of domestic and foreign patent information on existing recipes and methods for producing complex feed additives containing probiotic microflora for cattle. Introduction of probiotic cultures of microorganisms to feed additives, along with biologically active substances, allows us to influence the processes of microbiocenosis of the intestines of animals, and, therefore, digestibility and digestibility of feed, which, in turn, leads to an increase in animal productivity. In addition, probiotic cultures contribute to the biodegradation of mycotoxins, which helps prevent mycotoxicity of animals. The most popular in modern livestock breeding are complex feed additives with broad-spectrum probiotic preparations, performing various biological functions

The article presents the results of the patent research in the field of modern production technologies of Inulin from plant material. It has been established that the differences of the currently known methods of production of inulin are concluded in selecting raw materials pretreatment inulin-containing modes type extractant and extraction methods, methods of purification inulincontaining extract and methods for producing the final product. A significant amount of Inulin production methods is based on use of freshly feedstock. A number of methods have been patented involving the extraction Inulin from plant raw materials previously stabilized by drying. In most of the methods, inulin extraction is carried out at elevated temperatures with water or aqueous salt solutions. Several technologies involve extraction with organic solvents at low temperatures. Have been patented several processes in which the extraction is replaced by a separation process using inulincontaining juice and physical and mechanical methods. Some of the known processes provide for the extraction process to further operations, such as blanching vegetable raw materials, sonication, vibration impact, processing enzymes. The most promising direction to improve manufacturing technology of inulin from fresh plant raw materials is to conduct research on the use of electromagnetic fields at microwave frequencies, the inactivating effects of which on enzyme systems is an established fact that, in turn, would eliminate the use of chemical agents for inactivation of oxidative enzymes. In addition, considering that more effective are the methods for the preparation of inulin from freshly harvested plant material, are relevant researches on development of innovative technologies to prepare it for storage and its storage, which will provide inhibition of unwanted biochemical and microbiological processes that occur during storage and lead to a loss of inulin

The article analyzes the proprietary methods of processing of vegetable raw materials and secondary resources with the use of electromagnetic fields (EMF SHF). Analysis of the database of Rospatent World Intellectual Property Organization led to the conclusion that EMF SHF used in the processing of vegetable raw materials in the following processes: drying, reduction of microbial contamination (decontamination), juice production and extraction. It is established that the application of EMF SHF is the most effective in preparation for drying a plant raw material and not directly at the stage of drying, thus reducing the loss of heat-labile active compound in the drying process, and therefore obtain a finished product of higher quality and nutritional value. The patented methods of extraction of vegetable raw materials extraction process performed that extracting directly EMF SHF does not allow pre-hold inactivate enzymes contained in the raw material and lead to undesirable oxidative and hydrolytic processes, and hence a decrease in the yield of extractable substances in the extract and the deterioration of its quality . Therefore, as in the case of drying plant material, EMF SHF can be more effectively used in preparation for an extraction process. Based on the analysis, it was concluded that the relevance of developments in the field of technologies of processing of vegetable raw materials and secondary resources using EMF SHF at the stage of their preparation for such basic processes - drying, extraction, etc.
