The paper presents the results of the study of signs of long-term adaptation and indicators of reproductive qualities of sows of the universal direction of productivity, as well as calculates the economic efficiency of research results. The experimental part of the work was performed in the agricultural formations of the Dnipropetrovsk region and the laboratory of animal husbandry of the State Institution “Institute of Grain Crops of NAAS of Ukraine”. The work was performed in accordance with the research program № 31 “Genetic improvement of farm animals, their reproduction and conservation of biodiversity (Genetics, conservation, and reproduction of bioresources in animal husbandry)”, task – 31.02.01.18. pigs of different genotypes and to develop an integrated system for creating a highly productive population” (№ DR 0121U107903). Evaluation of sows on the indicators of long-term adaptation and reproductive qualities was carried out taking into account the following characteristics: life expectancy, months; duration of breeding use, months; farrowing was obtained; received piglets total, ch.; obtained live piglets, ch.; multiplicity, ch.; nest weight at the time of weaning at the age of 28 days, kg; safety of piglets before weaning, %. The index “level of adaptation” was calculated according to the method of Smirnov (2003), the index of reproductive qualities – according to the method of M. D. Berezovsky. Economic efficiency of research results and biometric processing of the obtained data were carried out according to generally accepted methods. It is established that sows of large white breeds of the controlled herd are characterized by rather high indicators of reproductive qualities and level of adaptation to conditions of intensive technology of operation. The life expectancy of sows in the main herd is 44.1 months, the duration of breeding use – 32.8 months, the index “level of adaptation” – 11.87 points. According to the indicators of fertility and nest weight at the time of weaning, the animals of the main herd belong to the first class and the elite class. Taking into account intra-breed differentiation according to the index “level of adaptation” sows of class M- significantly outperformed peers of class M+ in life expectancy by 54.77 %, duration of breeding use – by 71.48 %, index “level of adaptation” – by 66.09 %. Significant differences between groups of animals of these classes were found by multiplicity (td = 2.22; P < 0.05), nest weight at the time of weaning at the age of 28 days, kg (td = 2.56; P < 0.01) and index MD Berezovsky (td = 2.60; P < 0.01). The coefficients of pair correlation between traits that characterize the level of adaptation and reproductive qualities of sows range from -0.704 (tr = 10.80) to +0.982 (tr = 213.05). The use of sow class M- according to the index “level of adaptation” provides an increase in additional products at the level of +5.71 %, or 140.80 UAH. We propose to select repair young stock from sows of the leading group with the index “level of adaptation” of 6.55–8.08 points in the conditions of breeding plants and breeders, as well as industrial complexes.

The article presents the results of research on the reproductive qualities of sows of different breeding value, as well as determines the economic efficiency of their use in the industrial complex. The study was conducted in agricultural formations of the Dnipropetrovsk region (LLC "Druzhba-Kaznacheyivka", LLC "Vidrodzhennia") and the laboratory of animal husbandry of the State Institution Institute of Grain Crops NAAS. The work was performed according to the research program of NAAS №30 "Innovative technologies of breeding, industrial and organic production of pig products" ("Pig breeding"). Evaluation of sows on the grounds of reproductive qualities was carried out taking into account the following indicators: fertility, head; high fertility, kg, number of piglets at weaning, head, nest weight at the time of weaning at the age of 28 days, kg, nest weight at the time of weaning at the age of 60 days (estimated), kg, safety, %. The breeding value of animals was determined by the multiplicity and weight of the nest at the time of weaning (according to Annex 7 of the Instructions for grading pigs) and the selection index of reproductive qualities of sows (SIVYAS). The index of alignment (homogeneity) of the sow's nest by live weight of piglets at the time of their birth (ІВГ0) was calculated according to the method of V.I. Khalak (2012), the economic efficiency of research results - according to conventional methods. Biometric processing of research results was performed according to the methods of G.F. Lakin (1990). It was found that sows of the "elite" class were superior to peers of the "extracurricular" class in terms of multiplicity, several piglets at weaning, nest weight at weaning at 28 days and nest weight at weaning at 60 days (estimated) by an average of 28, 76%. The difference between sows of classes M + and M- (distribution class for SIVYAS) in terms of multiplicity, number of piglets at the time of weaning, the weight of the nest at the time of weaning at the age of 28 days and weight of the nest at the time of weaning at the age of 60 days (estimated) is 34.32. 34.78, 27.60 and 28.30 %, respectively. The coefficients of pair correlation between the absolute indicators of reproductive qualities of sows, the index "alignment (homogeneity) of the sow's nest by live weight of piglets at birth" and the selection index of reproductive qualities of sows (SIVYAS) at 83.33-100.0 % are reliable from -0.446 to +0.989. The criterion for the selection of highly productive animals according to the Instructions for grading pigs is the class "elite", according to the selection index of reproductive qualities of sows (SIVYAS) - 97.85-123.99 and more points. The use of sows of the class "elite" and М+ (according to SIVYAS) provides additional products at the level of +11.84 - 16.49 %.

The results of studies of life expectancy and breeding use, as well as the main indicators of reproductive qualities of sows of large white breed of different types of adaptation, the economic efficiency of the research results and the level of correlation between traits are calculated cost-effectiveness of research results and the level of correlation between traits. The research was conducted in the conditions of agro-formations of Dnipropetrovsk region (LTD “Agro-Elita”, SLTD “Druzhba-Kaznacheevka”). The object of the study was sows of large white breed. Evaluation of sows of experimental groups (I – superadaptive, II – mediumadaptive, III – minusadaptive type of adaptation) according to the indicators of the level of adaptation and the main indicators of reproductive qualities were carried out taking into account the successor of quantitative traits: life expectancy, months, duration of breeding use, months, farrowing received, piglets total, head; live pigs obtained, naked; multiplicity, head; weight of the nest at the time of weaning at the age of 28–35 days, kg; duration of intergrowth, days. The adaptation level index and the coefficient of productivity were calculated according to the method of Smirnov V. S. (2003) and Long T. E., Short T. H., Bates R. O (2003) respectively. The economic efficiency of the research results was calculated by according to the indicator “mass of the nest at the time of weaning at the age of 28–35 days, kg”. Analysis of the research results shows that sows of superadaptive type will outperform peers of the opposite class (minusadaptive type) in terms of adaptation level and reproductive capacity by 58.36 and 43.63 % respectively. The proportion of indicator “duration of breeding use, months” to the indicator “life expectancy, months” in animals of superadaptive type is 81.8 ± 0.76 %, minusadaptive – 54.1 ± 2.67 % (lim = 27.7 %; td = 10.00; P < 0.001). An integrated assessment of sow reproductive performance by the performance factor confirms the superiority of sows of the superadaptive type to this group of animal traits of other adaptation types. The paired correlation coefficients between adaptation level indices and reproductive traits in sows of different types of adaptation range from -0.815 (tr = 6.45; adaptation level index × obtained farrowing) to +0.995 (tr = 45.05; life expectancy × duration of tribal use). In order to accelerate the breeding process and create a high-yielding herd of pigs, we suggest that the leading group of sows select animals with an index of “adaptation level” of 6.55–8.90 points.

The article presents the results of studies of indicators of reproductive qualities of sows of large white breed of various intrabreed differentiation according to some evaluation indices, the criteria for selecting highly productive animals and the economic efficiency of their use are determined. On the basis of experimental data, аppendix 10 to the Instruction on the grading of pigs (correction factor for correcting the weight of the piglet nest at weaning at 60 days of age) has been modified and a new method has been developed for assessing sows according to the indicator "uniformity (uniformity) of a sow's nest in terms of live weight of piglets at weaning time" (IVG60). The studies were carried out in the «Druzhba - Kaznacheevka» JLLC in the Dnepropetrovsk region and the animal husbandry laboratory of the State Institution Institute of Grain Crops of the NAAS. The work was carried out in accordance with PSR NAAS No. 30 “Innovative technologies for pedigree, industrial and organic production of pig products (“Pigbreeding”). The assessment of sows in terms of reproductive qualities was carried out taking into account the following characteristics: multiple fertility, head, large fertility, kg, number of piglets at weaning time, head, nest weight at weaning time, kg (actual), nest weight at weaning time of 60 days, kg (calculated), safety, %. A comprehensive assessment of sows in terms of reproducti-ve qualities was carried out according to breeding indices of reproductive qualities of sows (SIVKS) (A. N. Tserenyuk et al., 2010), the index of N.D. Berezovsky (cited by P. A. Vashchenko, 2019), biometric processing of research results – according to the methods of G. F. Lakin (1990). It was found that 26.4 7 % of sows of the controlled herd, according to the characteristics of reproductive qualities (abundance, head, nest weight at the time of weaning at the age of 60 days (calculated), kg) belong to the elite class, 65.44 – I class, 7.35 – II class. The number of animals, according to the average score, are categorized as "out of class" is 0.73 %. The multiplicity of sows is 11.1 ± 0.15 heads. (Cv = 15.76 %), large fruit – 1.41 ± 0.009 kg (Cv = 7.88 %), the number of piglets at weaning time – 9.7 ± 0.13 head (Cv = 16.60 %), weight nests at the time of weaning, kg (actual) – 74.3 ± 0.85 kg (Cv = 13.48 %), weight of the nest at the time of weaning in 60 days, kg (calculated) – 175.9 ± 2.160 kg (Cv = 13.43 %), safety – 87.9 ± 0.49 % (Cv = 6.84 %). The index of uniformity (uniformity) of a sow's nest in terms of live weight of piglets at the time of birth is 5.21 ± 0.076 points (Cv = 17.11 %), at the time of weaning – 8.32 ± 0.156 points (Cv = 21.98 %), selection sow reproductive qualities index (SIVKS) – 88.31 ± 1.118 points (Cv = 14.77 %). Coefficients of pair correlation between the estimated indices IVG0, IVG60, SIVKS and signs of reproductive qualities range from -0.438 (index of uniformity (uniformity) of the nest of a sow in terms of live weight of piglets at the time of weaning, point (IVG60) × large fruit) to + 0.988 ± 0, 0020 (breeding index of reproductive qualities of a sow (SIVKS) × multiple pregnancy). The maximum increase in additional products received from animals of class M+ – 27.60 %, and its cost is equal to 685.33 UAH/head. Key words: sow, reproductive qualities, integrated assessment, evenness (uniformity) of the nest, variability, correlation, economic efficiency.

Key Characteristics

The tropical ecosystem had high biomass productivity but still less in economic values. Integrated Bio-cycle Farming System (IBFS) was an alternative system that harmoniously combines agricultural sectors (agriculture, forestry, animal husbandry, fishery, plantation estate, horticulture) and non-agricultural aspects (industry, household, infrastructure, the marketplace) on integrated ecological management. The key characteristics of IBFS developed in UGM University Farm were (i) an integration of agriculture and non-agriculture sector, (ii) value of environment, esthetics and economics, (iii) rotation and diversity of plants, (iv) artificial and functional biotechnology, (v) management of closed organic cycle, (vi) ecosystem health management, (vii) agropolitan concept, (viii) specific management of plant and (ix) holistic and integrated system. The management of cycle of energy, organic matter and carbon, water, nutrient, production, crop, money conducted through 9R (reuse, reduce, recycle, refill, replace, repair, replant, rebuild, reward) to obtain optimal benefits for global environment and livelihood. The system had a sustainable multifunction and multi-product (food, feed, fuel, fiber, fertilizer, biopharma, water, energy, oxygen, edutainment, eco-tourism). They would meet the expected basic need for daily-, monthly-, yearly- and decade’s income at short-, medium- and long- term periods. IBFS was a good prospect for sustainable economic, environmental, and socio-culture aspects.

SUMMARYMany valuable local breeds of farm animals in the USSR have either been lost or are in an endangered state. Concern about this loss of gene resources has led to the inclusion of a genetic resources programme in the overall state plan for the genetic improvement of livestock. It includes programmes for live animal conservation and setting up of gene banks. The former activity is carried out in special state gene pool farms, one for each geographical zone, where 500 purebred cows are maintained under a rotational outbred system of mating. Semen banks of most local breeds of livestock have also been established at animal husbandry institutes. Current research emphasis is on long term embryo storage and establishment of banks of somatic cells of local breeds.

Modern animal husbandry in Ukraine is an integral part of the market economy and is based on the use of advanced production technologies and not a large number of highly productive domestic or foreign breeds of farm animals. It has been established that the progress of the livestock industry is not possible without determining the changes that occur with breeds and livestock of breeding animals in the subjects of breeding business. It is well known that only breeding animals are able to display high genetic potential for productivity and to pass it on to offspring. Understanding of the state of the breeds is necessary to forecast product volumes that are consistent with country safety, and to determine the populations that need to be preserved or restored in the context of the global problem of wildlife biodiversity conservation. The purpose of the work was to identify the species and breeds of farm animals that have formed the livestock sector of Ukraine at the beginning of the third millennium, and to identify changes that have occurred with the genetic resources of farm animals and to identify the breeds most vulnerable to the number of females under control. Analysis of the state of dairy and combined dairy and meat breeds in the breeding herds of Ukraine made it possible to conclude that as of January 1, 2019, compared to the beginning of 2002, the number of cows in Ayrshire, Angler, Lebedyn, Simmental, Ukrainian Red-and-White Dairy, Ukrainian Black-and-White Dairy, Polish Red and Red Steppe decreased breeds. The increase in the number of cows occurs among the Ukrainian Whiteheaded, Holstein and Swiss breeds. Breeding herds for breeding cattle of Carpathian Brown, Ukrainian Brown Dairy  breeds and Pintsgow are not functioning. The endangered include Angler, Ukrainian Whiteheaded, Ukrainian Brown Dairy and Polish Red breeds. A comparative analysis of the number of cows of beef breeds in the subjects of breeding business of Ukraine in the dynamics of 2002–2019 indicates the preservation of all breeds, except for pentiges. In 2019, compared to 2002, cows increased in herds of Aberdeen-Angus breed, Hereford, Limousine, Southern Beef, Polissian Beef, Light Aquitan, Ukrainian Gray and Charolais. A significant decrease in the number of cows in Volinian Beef breed, the Znamensk type of Polissian Beef, Simmental Beef and Ukarainian Beef. The few in Ukraine at this stage include Hereford, Light Aquitan and Ukrainian Beef. The state of pig breeding in the breeding farms on 01.01.2019 indicates the disappearance of breeding herds in which pigs of English selection Large White breed, Large Black and Myrgorod breeds were breed. At present, only Large White breeds and Landrace pigs can be competitive in numbers, and the rest should be considered non-numerical. Sheep breeding, which is represented in Ukraine by the largest number of breeds and breed types, did not have any breeding herds in 2019, where in previous years bred Askanian Fine-Fleece breed, Askanian type of Black-Headed sheep with crossbred fleece, Olibs, North-Caucasian, Polwars, caucasian the Kharkiv type of the Ukrainian Meat-Fleece breed, the Tsigai breed and its two types, as well as the multi-breed type of the Karakul breed. Simultaneously with the disappearance of the above breeds new breeds or types appeared, among them: Bukovyna type of Askanian Meat-Fleece breed with crossbred fleece, Merinolandshaft, Dniprovian Meat  (Dnipropetrovsk type), Romanivska. The smallest number of breeding queens of falcon and dark-headed Latvian breeds was established. The changes that took place in the field of horse breeding of Ukraine during 2002–2019 relate to the creation and elimination of breeding herds in which horses were bred by Budyonnivska, Russian Heavy Draft and French Trotter breeds. No information is available in the State Register of Breeding Herds about the Gutsul and Torian breeds, as well as the Shetland Pony, may be regarded as the disappearance of these breeding herds. In 2019, compared to 2002, the number of mares of Newolexandrian Heavy Draft, Orlov Trotter, Russian Trotter, Trakenian, Ukrainian Saddle and Thoroughbred Saddle horse breeds declined significantly. The gene pool of horses has expanded only due to the Hanover breed. Analysis of the status of other species and breeds of farm animals is not optimistic and indicates a decrease in the number of females and, consequently, a decrease in the gene pool of these breeds.Without the introduction of effective state conservation and support programs, as well as policy changes in the agricultural sector, Ukraine will continue to reduce livestock of agricultural animals, especially domestic autochthonous or local breeds, continuing the sad tradition of the world in reducing breed biodiversity.

The purpose of the article is to highlight the main milestones in the life and creative path of the famous scientist in the field of animal husbandry, Doctor of Biological Sciences, Professor I. V. Smirnov, his contribution to the formation of the sectorial experimental work and the spread of higher professional education. Research methods – general scientific (analysis, synthesis, classification), special historical (problem-chronological, comparative-historical, biographical), source studies. The scientific novelty of the article lies in the detailed study of the Terezyno period of I. V. Smirnov's activities, during which the new technological solutions were established and implemented contributing to the development of the theory and methodology of artificial insemination of farm animals. It is proved that on the basis of the Kiev Experimental Station of Animal Husbandry "Terezyno" the scientist implemented the concept of the development of higher professional education, based on the combination of the educational process with long-term industrial practice; laid the foundations for international cooperation in the field of reproduction biotechnology in animal husbandry. The main components of the I. V. Smirnov's creativity are highlighted, namely: methods of sperm long-term storage, technologies and techniques of artificial insemination, biology and physiology of reproduction of farm animals, etc. The researcher developed the theory of anabiosis, the theory of cold sperm shock, established the methods for mammalian sperm diluting and evaluating. He updated research on the use of blood groups for testing the lineage of animals and artificially regulating the sex of the offspring. It is shown that the method of mammalian sperm long-term storage formed the theoretical basis for the reorganization of domestic breeding on the basis of the widespread introduction of artificial insemination, contributed to a fast transformation of the gene pool of farm animals due to the involvement of genetic resources of foreign breeding in the selection process. It has been proved that thanks to the I. V. Smirnov's creative initiatives, the foundations have been laid for the development of a new direction in the science of the reproduction of organic species – reproductive biotechnology of farm animals.

Многолетними исследованиями с люцерной (1997–2020 годы) показано, что в перспективе эта культура может занять достойное место среди кормовых культур, возделываемых в хозяйствах Дальнего Востока. В связи с приоритетным развитием животноводства актуально внедрение люцерны в научно обоснованные кормовые севообороты, что стабилизирует посевные площади кормовых культур, покроет дефицит белка, снизит себестоимость животноводческой продукции. Люцерна — универсальная культура, имеющая огромное значение в системе устойчивого сельского хозяйства, в решении проблемы производства энергонасыщенных высокобелковых кормов и восстановления почвенного плодородия Дальневосточного региона. Агромелиоративная роль люцерны заключается в обогащении почвы питательными веществами, увеличении количества ценных водопрочных агрегатов, увеличении коэффициента структурности почвы. Это обеспечивается хорошо развитой подземной массой, способствующей снижению водной и ветровой эрозии. Для обеспечения высокой продуктивности люцерны в условиях Приморского края наряду с агроприёмами большое значение имеют правильно подобранные участки и организованная система использования травостоев в строгом соответствии с биологией культуры. Современные сорта люцерны более продуктивны, зимостойки, менее требовательны к термическим и эдафическим факторам окружающей среды, устойчивы к повышенной кислотности почвы, т.е. вполне реально подобрать сорта люцерны для почвенно-климатических условий Дальневосточного региона. При соблюдении технологических приёмов возделывания, таких как известкование, внесение минеральных и органических удобрений (птичьего помёта), инокуляция семян перед посевом, подбор травосмесей, оптимальный способ и срок посева и т.д., можно создать высокопродуктивный травостой длительного пользования, обеспечивающий сельскохозяйственных животных сбалансированными кормами отличного качества. Long-term experiments on alfalfa (1997–2020) have shown that it is a promising crop for the farms of the Far East. Due to the active development of animal husbandry, it is important to introduce alfalfa into optimized feed crop rotations. This will stabilize the stands of feed crops, cover the protein deficit, and reduce the cost of livestock products. Alfalfa is a universal crop for sustainable agriculture, producing energy-rich high-protein feed and restoring soil fertility in the Far East. Alfalfa is a meliorative crop: it enriches the soil with nutrients, increases the number of valuable water-resistant aggregates and the coefficient of soil structure. This is obtained by a well-developed underground mass, which helps to reduce water and wind erosion. To obtain high productivity of alfalfa in the Primorsk Territory, besides cultural practices, effective field and sward usage is of great importance. Modern alfalfa varieties are more productive and resistant to frost, soil stresses and increased soil acidity, i.e. it is possible to choose alfalfa varieties for the soil and climatic conditions of the Far East. Developing a long-term highly productive swards, providing farm animals with balanced feed of excellent quality, is directly dependent on cultural practices, such as liming, application of mineral and organic fertilizers (bird droppings), seeds inoculation, selection of grass mixtures, optimal method and time of sowing, etc.

The article deals with the reproductive qualities of Large White breed sows of Hungarian origin and their operational value. We also determined they economic efficiency. The experimental part of the research was conducted in agricultural formations of Dnipro region (AALLC "Druzhba-Kaznachejivka", Ltd. "Vidrodzhennja") and livestock laboratories of the State establishment Institute of Grain Crops NAAS. Evaluation of sows on the main indicators of the level of adaptation and reproductive qualities was performed taking into account the following quantitative characteristics: life expectancy, months, duration of breeding use, farrowing was obtained, total piglets were obtained, heads, live piglets were obtained, heads, fertility of heads, nest masst at the time of weaning at the age of 28 days (kg), preservation (%), duration of between farrowing period, days, number of unproductive days per farrowing. It is defined that sows of Large White breed of the controlled herd on the main indicators of reproductive qualities (fertility, head; nest mass at the time of weaning at the age of 28 days, kg) meet the minimum requirements of class I and elite class. A significant difference between the groups of animals of the categories "high operational value" and “low operational value” was defined by indicators “life expectancy, months” (29.9 months, td = 13.71), ”duration of breeding use, months” (29.6 months, td = 14.50), "farrowings were obtained" (5.7 farrowings, td = 14.50), "total piglets were obtained, heads" (70.5, heads, td = 13.85), "obtained live piglets, heads" (67.7 heads, td = 20.83), "fertility, heads " (3.3 heads, td = 10.31), nest mass at the time of weaning at the age of 28 days (6.5 kg, td = 2.55). Coefficients of phenotypic consolidation of signs of reproductive qualities in sows of different operational value ranged from -0.785 to +0.856. The maximum supplement in additional products on the indicator “nest mass at the time of weaning at the age of 28 days, kg” was obtained from sows of the category "high operational value" - 6.03%.

One of the top priorities at the present stage of development of pig breeding remains the development of a set of measures aimed at increasing the resistance animals to various diseases, especially – to colibacteriosis .One of the recent and effective approaches to prevent colibacillosis is using markers of selection; it involves pig genotyping by genome locuses. Chosen locuses are associated with animal sensitivity to the disease and selection of the results of genotyping of animals with increased resistance. Due to researches, one of such locuses is alpha-fukozyltrasferаza 1 gene (FUT1). Gene FUT1 is located in chromosome 6. As a result of its sequencing in the swine breeds of Large White and Swedish Landrace, single-nucleotide polymorphism (g.307 G > A SNP) has been detected. AA genotype determines the resistance of animals to colibacteriosis, while AG and GG genotypes are susceptible to this disease. According to the results of previous studies, the positive effect of allele A was determined not only on the resistance of pigs to colibacteriosis, but also on indicators of fattening and meat productivity and on reproductive performance. In Ukraine, the studies of polymorphism FUT1 g.307 G > A SNP were held fragmentedly and only on certain populations of Ukrainian Meat and Large White breed but without establishing its association with the indicators of productivity of pigs. The aim of our work was to study the genetic structure of Ukrainian Large White breeds, type 1 and the establishment of association. g. 307 G > A SNP FUT1 gene with pigs indicators of productivity. For research the 96 samples of hair were used. DNA isolation from samples with biomaterial were carried out using ion exchange resin Chelex-100. Genotyping was performed by PCR-RFLP by method of Jorgensen et al. (2006). Using DNA analysis of this breeds locus FUT1 was determined by genetic structure. Allele frequency of allele G (0,573) and allele A (0,427) was established The distribution of genotype frequencies was not statistically significantly different from the theoretically expected, calculated by the Hardy-Weinberg criterion. Thus, according to the locus of FUT1 g.307 G > A, the breeds investigated are in a state close to the genetic equilibrium. The negative value of the fixation index by the locus FUT1 g.307 G > A indicates an excess of heterozygotes in the population, and hence the lack of targeted selection for this marker. The valuation was performed by calculating the PIC (polymorphic information content) – information content of polymorphism marker. In the analyzed pig herd for this marker, the PIC has an average value (0,367), which indicates the high level of polymorphism of the given locus and is favorable for the possibility of conducting a search for links between individual genotypes and indicators of productivity. To establish the association g.307 G > A SNP FUT1 gene with indicators of animal productivity, a one-way analysis of variance of the experimental data was used. Based on the results of a one-way analysis of variance, a significant effect of the genotypes of the FUT1gene (g.1849 G > C) on the indicator of the average daily weight gain (р ≤ 0,001), the thickness of the bacon at the level of the VI-VII vertebrae (p ≤ 0.01), reaching live weight of 100 kg (р ≤ 0,001) and breeding index of fattening qualities (р ≤ 0,01) was found. The parameter of the influence of the genetic factor on the test feature was 28,54%, 10,4%, 33,4% and 8,8% respectively. According to the investigated indicators of productivity, animals with genotype AA, which determines resistance to colibacteriosis, dominated the animals with genotypes GG and AG. Based on the results of our research and pre-published data, the multiple effect of the g.307 G > A SNP FUT1 gene is observed, which is associated with the indicators of productivity, which again confirms the polygenicity of the quantitative trait loci of farm animals. Taking into account a high level of polymorphism of the investigated gene and reliable associations of genotypes with indicators of productivity found, it can be recommended to carry out breeding of pigs using genetic information of the g.307 G > A SNP gene FUT1.
