The introduction of the newest technologies of organic pig breeding has the basic principle of minimizing the use in pigs of chemicals, trace amounts of which in pig production adversely affect the quality of products and the health of consumers. The transition to herbal remedies, the maximum possible rejection of chemical synthesis products, is inhibited, in the main, by the relatively small spectrum of plant compounds with the investigated activity. According to the results of previous studies, six working solutions of Juglans regia L phytosupply extracts - potential phytosine disinfectants were developed: To investigate the bactericidal activity of the experimental preparations of Juglans regia, flushes were made from the internal structures and technological equipment of the housing of the pig stock of the experimental base v. Takhtaulove. Obtained samples of typical banal microflora of the pig complex were mixed to obtain a bacterial-containing suspension averaged over the concentration of microbial bodies and the spectrum of types of microflora in the microbiota. When cultured on nutrient media, with the superficial sowing of a suspension of banal microflora of a pig in the presence of a potential phytodisinfectant, processes of development of individual colonies of the microflora are observed. The amount and intensity of their development, the degree of inhibition of life, assess the level of bactericidal activity of the extracts. The highest bactericidal and fungicidal activity, and consequently, the potential efficacy as a possible disinfectant in the technology of organic pig breeding was revealed by the extracts of phytosupply Juglans regia L No. 2 (extractant - acetic acid to 5 %, nut of wax ripeness) and 4 (extractant, alcohol 20 % nutrient wax ripeness (proven after obtaining the primary extract of up to 5 % alcohol), which have bactericidal properties against gram-positive cocci and gram-negative sticks, but have a weak effect on the spore-forming bacilli. Key words: organic pig breeding, bactericidal activity, phyto-disinfectant, commonplace typical microflora of a pig complex, phyto row materials, walnut extract.

Apples are seasonal fruits, and thus after harvesting apples of optimal picking maturity, it is important to prepare them properly for storage and to ensure proper storage conditions in order to minimize changes in the chemical composition and commercial quality of the apples. We studied the quantitative composition of triterpenic compounds in the whole apple, apple peel and apple flesh samples before placing them in the controlled atmosphere (CA) chambers, and at the end of the experiment, 8 months later. HPLC analysis showed that highest total amount of triterpenic compounds (1.99 ± 0.01 mg g−1) was found in the whole apple samples of the ‘Spartan’ cultivar stored under variant VIII (O2—20%, CO2—3%, N2—77%) conditions. Meanwhile, the highest amount of triterpenic compounds (11.66 ± 0.72 mg g−1) was determined in the apple peel samples of the ‘Auksis’ cultivar stored under variant II (O2—5%, CO2—1%, N2—94%) conditions. In the apple peel samples of the ‘Auksis’ cultivar stored under variant I (O2—21%, CO2—0.03%, N2—78.97%) conditions, the amount of individual triterpenic compounds (ursolic, oleanolic, corosolic, and betulinic acids) significantly decreased compared with amount determined before the storage. Therefore, in the apple flesh samples determined triterpenic compounds are less stable during the storage under controlled atmosphere conditions compared with triterpenic compounds determined in the whole apple and apple peel samples.
