PROBIOTIC FEED ADDITIVES USED IN PIG FARMING

abstract 1572003001 issue 157 pp. 1 – 13 31.03.2020 ru 354
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

abstract 1301706050 issue 130 pp. 727 – 738 30.06.2017 ru 690
The article provides an overview of Express-methods of quality evaluation and identification of lipidcontaining plant raw materials (oil seeds) and its processed products (oil cakes, oilseed meals, vegetable oils, lecithins) using pulse method of nuclear magnetic resonance. Development of express methods of quality evaluation and identification of lipid-containing plant raw materials and products of its processing is a priority, as these methods are environmentally safe and also allow us to regulate technological conditions of refining processes, are characterized by low error of determination, i.e., high precision, and, in some cases, it is only possible to use because of its non-destructive effects on the analyzed sample. Currently, we can distinguish the following main directions of quality evaluation and identification of lipid-containing plant raw materials and products of its processing on the basis of the pulse method of nuclear magnetic resonance: assessment of quality and identification of oilseeds (sunflower, canola, flax, soybeans); evaluation of quality of products of processing of oil raw materials (cake and meal); the quality evaluation and identification of vegetable oils; assessment of the quality of the lecithins obtained from vegetable oils. The methods of quality evaluation and identification of lipid-containing plant raw materials and its products are patented and have several advantages: short time (5 minutes) spent on the implementation of the single analysis; eliminates the use of toxic chemicals; does not require special training of laboratory personnel; non-destructive character, which is especially important for oilseeds from the point of view of breeding work. On the basis of the conducted survey we can conclude that the pulse method of nuclear magnetic resonance has found wide application for assessment of quality and identification of lipidcontaining plant raw materials and products of its processing, through rapid capabilities, high accuracy and ease of analysis

abstract 1271703051 issue 127 pp. 745 – 753 31.03.2017 ru 686
There were presented comparative analysis’ results of criteria rice quality used in Russian and international standards. Also there were shown summarized statistical analysis’ results of rice quality that was processed in 2013-2016 on rice mill plant at “Krasnodarzernoprodukt” Company. The purpose of research was to find factors that had influence on combining rice bulk effectiveness on specialized elevator. It was found that diapason of rice moisture content was quite small. Red rice content was ranging from 1.08 to 5.10 % with confidence interval of 1.98- 2.56 % that is evidence of small amounts of rice bulks with extreme high or low red rice content. Broken rice content varied in the wide range from 3.43 to 9.26 % with confidence interval from 5.84 to 7.26 % that shows necessity in length grading procedure applying for broken kernels removing at the elevator unit. Grain impurities content exceeded basic norm in 3-4 times that is a sign of low efficiency in the process of separation. During the treatment of rice bulks combined at the grain cleaning unit of rice plant broken rice cereals output varied in wide range from 3 to 9 % during single shift that is seems to be connected with kernels cracking increasing and rice moisture decreasing. Moreover, rice bran output also varied in a wide diapason from 10.2 to 17.0 % that could be explained by big swing in rice moisture, glassy texture and cracking of rice grains. According to our research it was investigated that current rice quality control system that is a base instrument of rice bulks forming for further processing is not quite efficient and as a result there should be created and implemented new methods and technical devices for quick and proper grain control that could assure stable technological regimes at different stages of rice treatment process and that would provide the best quality and the biggest output of rice cereals
