The possibility of including SUB-PRO probiotic instead of Maxus G feed antibiotic in the diet of broiler chickens of Ross 308 cross was studied to obtain products free of drugs for antimicrobial resistance usage. The dynamics of live weight and carcass weight of cockerels at 1-, 21-, 28-, 34-, 38- and 42-days old was determined. The males of the control group (group 1) reached live weight of 2619 ± 44.9, experimental - 2739 ± 46.2 or more by 4.38%, at P≤0.05 by 42 days of age, and those which received feed antibiotic ( group 3) - 2677 ± 45.1 (further, meat productivity of the latter was not studied, since they are not of practical importance). The mass of carcasses of the experimental group was equal to 1704 ± 23.1 g, which is 4.60% more than the control, at P≤0.05; the relative mass of muscle tissue increased with age by 10.78% in the experimental group in comparison with the 1-day -olds, in the control group - by 10.0%, whereas the mass of bones decreased by 16.75 and 16.59%, respectively (by the difference); the diameter of muscle fibers of superficial pectoral muscle of 42-day-old broilers of the experimental group increased with age by 6.94 times and amounted to 57.9 μm; in terms of microbiological parameters, carcass meat meets the requirements of the interstate standard GOST 31468—2012. At the age of 42 days, cockerels of the control group showed dystrophic changes in the superficial pectoral muscle in the form of an expansion of the endomysium diameter, with the accumulation of interfiber fluid (albuminous degeneration), while some cockerels of the experimental group have fibers with vacuoles and infiltration by immunocompetent cells (leukocytes, phagocytes). Adding SUB-PRO probiotic in the broilers’ diet instead of the feed antibiotic does not reduce productivity, but excludes the negative consequences of feed antibiotics.

The article provides a comparative analysis of Czech and Russian literary and dialectal phraseological units that characterize a wealthy person and prosperous life. Contemporary studies mostly deal with literal and colloquial idioms, whereas dialectal phraseology is rarely used for the comparative studies. It may stem from the fact that there are no large dictionaries of Russian dialectal phraseology. For this article, we used the materials for the Phraseological Dictionary of Russian Folk Dialects, which is being prepared under the supervision of prof. V. M. Mokienko. The Russian part of the research is represented by approximately 250 idioms, the Czech part totals about 150 units. Czech and Russian phraseological units were grouped together according to their common internal image,the themes of components, similar syntactic models, or similar logical motivations. As an example in the group that combines Czech and Russian phraseological units with a similar figurative basis, we show the model 'animal or bird refuses to eat any kind of food' known in different languages. There are different variants of the model known to Czech and Russian dialects, which represent different animals and birds, and different types of food. The analysis of the idioms grouped together on the basis of the themes of their components have led to the conclusion that in Czech and Russian idioms, the image of wealth is often interpreted through the images of money, storage, satiety, food (mostly fat-heavy and also sweet – in Russian idioms), fantastic abundance, etc. For the Russian dialect phraseology, we describe one characteristic syntactic model, which marks a rich person: one cannot be reached / hurt with any tool. This model was not found in Czech idioms. A comparative analysis showed that in Russian dialect phraseology, which characterizes a comfortable life, one often observes tautological constructions with the lexeme ‘live’. In the Czech part of the materials, there was no tautology. Thanks to the dialectal phraseology the materials for the comparative study of the Czech and Russian idioms have qualitatively and quantitatively grown. Because of these dialectal units, parallels in the semantics and syntactic structure of many phraseological phrases in the studied languages have been made obvious. We have also managed to identify several Czech-Russian phraseological internationalisms, further historical and etymological study of which seems to bring us closer to the issue of the typological or genetic similarity of these idioms in two Slavic languages. Usage of dialect phraseology also lets us reveal several syntactic features typical only for Russian phraseology.

We studied dynamics of live weight and morphological composition of carcasses in Ross 308 chickens at 1-, 21-, 28-, 34-, 38- and 42-day ages when SUB-PRO probiotic was included in the diet instead of Maxus G feed antibiotic in amount of 100 g/ton of feed. By the age of 42, chickens in the control group (I) reached a live weight of 2234 28.4 g, chickens in the experimental group (II) - 2329 27.3 g, and chickens who took feed antibiotic (III) - 2320 33.4 g. Live weight of chickens of the II group by the age of 42 days exceeded the I group by 95 g or 4.25 % (P 0.05), the III group - by 86 g or 3.85 %. In terms of carcass weight, the experimental group exceeded the control group by 4.60 % (P 0.05), group III - by 4.53 %. The meat productivity of chickens taking antibiotic was not studied further, since that had no practical significance. Over the entire period of rearing, the average daily gain in live weight in control chickens was 52.20 g, in the experimental chickens - 54.46 g. The relative muscle weight in broiler carcasses of the experimental group increased from 55.34 to 66.37 %v from 1 to 42 days of age, while the relative bone weight decreased from 33.23 to 16.78 %. By the age of 42, absolute muscle and bone weight had 123.47- and 51.91-fold increase, respectively, in comparison with diurnal weight. The data of anatomical cutting of chicken carcasses showed that, in terms of muscle and bone content, the most valuable were: breast - 84.63 and 8.25 %, thigh - 75.66 and 12.54 %, respectively; less valuable: drumstick - 67.86 and 20.98 %, wing - 50.58 and 33.53 %, respectively. Diameter of muscle fibers of superficial pectoralis muscle in 42-day-old broilers was 55.20 m; water content - 75.10 %, fat - 1.60 %, protein - 22.31 %. In terms of microbiological parameters, carcass meat meets the requirements of GOST 31468-2012 interstate standard. The inclusion of SUB-PRO probiotic in chicken diet instead of antibiotic does not reduce productivity, but excludes the negative consequences of antibiotic use.
