The researches were carried out in ООО “Rossyia” of the Mozhginsky district of the Udmurt Republic. The object of the research was the sows of the main herd of a Large White pig breed. The reproductive qualities of the sows were studied according to such indicators as: the multiple births, the milkness, the mass of a nest in 2 months. The study of reproductive qualities was carried out using breeding cards of the sows and a book for registering farrowing and offspring of the pigs. The evaluation of the reproductive qualities of sows was carried out by calculating the indicators of a variational statistics: the arithmetic mean, the mean quadrate deviation, the coefficients of the variation, the heritability, the correlation. The indicator of a variational statistics was calculated according to the method of N.A. Plokhinsky. The reliability of the coefficients of the heritability and the correlation was determined using Student's t-test. Then studying the reproductive qualities of the sows of the main herd it was established that the multiple births in the average was 10.61 heads, the milkness — 51.34 kg, and the mass of a nest in 2 months — 156.72 kg. Hereat the coefficient of the variability on the multiple births was 12.95%, on the milkness — 8.41%, and on the mass of a nest in 2 months — 10.02%. The coefficient of heritability on the multiple births was 15.00%, on the milkness — 20.00%, and on the mass of a nest in 2 months — 25.00% (P > 0.999). The coefficients of the correlation between the multiple births and the milkness and the multiple births and the mass of a nest in 2 months, respectively, were r = +0.769 and r = + 0.474, and the coefficient of the correlation between the milkness and the mass of a nest in 2 months — r = + 0.754 under the probability of the infallible prognoses P > 0.999.

The results of studies of the reproductive ability of sows of different genotypes are given taking into account the polymorphism g.1426G> A of the MC4R gene, the factor of repeatability of characters is determined, and the economic efficiency of the research results is calculated. The experimental part of the research was carried out in the conditions of the «Druzhba-Kaznacheevka» LTD in Dnipropetrovsk region. The objects of research were sows of the Large White breed. It was determined that sows of the main herd, according to signs of reproductive ability, belong to class I and class elite. The experiment showed that sows of genotype AG exceeded their peers of others (GG and AA) in terms of “born piglets total, heads” by 1.6 and 0.7 heads, “Live piglets born (multiple births), heads - by 1 6 and 0.9 heads, “the mass of the litter at the time of birth, kg” - by 2.7 - 1.3 kg., “the mass of the litter at the time of weaning at the age of 28-35 days, kg” - by 5, 1 - 3.9 kg. The difference between animals of the indicated genotypes is: for large-foetus - 0.06-0.01 kg, the index "evenness of the sow’s litter in live weight of piglets at birth, points" - 1.05-1.84 points, index of N. D. Berezovsky - 3.75 -2.36 points. The index of the safety of piglets before weaning ranged from 84.4 to 93.0 %. It was proved that the minimum value of the index “evenness of the sow’s littar in live weight of piglets at the time of birth, points (7.76 ± 1,082 points) are characterized by sows of genotype AA, in which the rate of multiple pregnancy ranged from 8 to 14 pigs, and the value of the sign“ large-foetus, kg "equaled 1.37 kg. The repeatability coefficient for sows of the main herd and sows of the Large White breed of different genotypes for the melanocortin 4 (MC4R) receptor gene ranges from -0.916 ± 0.1418 (І-IV farrow, genotype - GG, sign - “piglet safety before weaning, %) to 0.978 ± 0.0738 (I-V farrow, genotype - GG, sign - “large foetus”, kg ”). The maximum value of the phenotypic consolidation coefficient was found in sows of genotype AA according to the following quantitative characteristics: “live piglets (multiple births), heads.”, “litter weight at the time of birth, kg”, “litter weight at weaning age of 28-35 days, kg "," the safety of piglets before weaning ,% ". The sows of the genotype GG belong to the unconsolidated group according to the signs of reproductive qualities. The use of sows of the genotype for the melanocortin 4 (MC4R) AG receptor gene provides additional products at the level of 5.15 %, and its cost is 165.41 UAH /head.

The Large White pig is the most commonly raised commercial pig breed in the world. The aim of this work was to investigate D-loop mtDNA in Large White pigs (n = 402) of various selections bred in the Russian Federation from 2000 to 2019. The general sample consisted of three groups: Old (n = 78) (Russian selection, 2000–2010); Imp (n = 123) (imported to Russia in 2008–2014); New (n = 201) (2015–2019). The synthesized score (Fz) was calculated by analyzing the main PCA (principal component analysis components). An affiliation to Asian or European haplogroups was determined according to the NCBI (National Center for Biotechnology Information). In the study, we defined 46 polymorphic sites and 42 haplotypes. Significant distinctions between groups Old, Imp and New in frequencies of haplotypes and haplogroups were established. The distribution of Asian and European haplotypes in the groups was Old: 50%/50%, Imp: 43%/57%, New: 75%/25%, respectively. The variety of haplotypes and haplogroups in the pigs of the group New is related to the farms in which they breed. Haplotype frequencies significantly differ between the clusters Old_Center, Old_Siberia and Old_South. This study will provide information on the genetic diversity of Large White breed pigs. The results will be useful for the conservation and sustainable use of these resources.

The research was carried out on the basis of the farm of LLC "Russia" Mozhginsky district of the Udmurt Republic. The object of research was sows of the main herd of Large White breed in the amount of 100 heads. The age of the sows was 24 months under two farrows in the year. The aim of the research was evaluation of the  reproductive qualities of the sows of the main herd in the context of families, by calculating a complex indicator of the reproductive qualities. The index evaluation of the reproductive qualities was carried out to take into account such indicators as: the prolificacy, the milkness, the number of piglets in 2 months and the masse of the nest in 2 months. The obtained experimental data were processed in a tabular redactor program Microsoft Excel - 2010. The evaluation of the reproductive ability of the sows in the main herd in the context of families showed that the sows of the families Beatrisa, Ovatsia and the Volshebnitsa differed from the sows of the families Skazka, Soya and the Palitra more higher prolificacy- by 0.36-1.44 heads, a mass of the nest in 2 months - by 2, 58-22.46 kg and the number of piglets in 2 months - by 0.35-0.78 heads. The complex indicator of the reproductive qualities of the sows of the families Beatrisa, Ovatsia and the Volshebnitsa, exceeded the complex indicator of the reproductive qualities of the families Skazka, Soya and the Palitra by 3.52-12.82 points.  The evaluation of the reproductive qualities of the sows of the families Beatrisa, Ovatsia and the Volshebnitsa showed that they exceeded the average level on the herd on the prolificacy- by 3.04 heads, the mass of the nest under weaning piglets in 2 months of age - by 9.03-28.72 kg, the number of the piglets under weaning in 2 months of age - by 0.62-1.64 heads, and on the complex indicator of reproductive qualities - by 8.90-19.39 points. The results of the research made it possible to select the best sows for the breeding stock and use them widely in the reproduction of the herd.

Leptin receptor is one of the components of the system of regulating energy homeostasis of the organism. Leptin receptor gene (LEPR) polymorphism is associated with pig carcass index of the content of intramus- cular fat in its valuable parts, which is particularly important when assessing the quality of their carcasses for processing. Intramuscular fat is associated with meat fl avor characteristics and partly determines its tenderness, juiciness, and other parameters. Aim. To analyze LEPR gene (SNP NM001024587.1, p. 1987 C > T) polymor- phism in populations of various pig breeds and to establish its relationship with the quality of both meat and fat of pigs of Large White breed of Ukrainian breeding. Methods. Genetic-population analysis of nine pig breeds, associative analysis on the search connection of LEPR gene polymorphism with quality of both meat and fat of pigs of Large White breed of Ukrainian breeding. LEPR locus genotyping was performed by High Resolution Melting (HRM). Results. All the studied breeds are characterized by polymorphism of the leptin receptor gene (SNP NM001024587.1, p. 1987 C > T), signifi cant breed specifi city in the distribution of frequencies of alleles was established. Statistically confi rmed effect (p < 0.05) of genotypes LEPR on the content of intramuscular fat, total dry matter and moisture in the meat, as well as the moisture content in the back fat of pigs of Ukrainian Large White breed was revealed. Higher content of intramuscular fat was found in the animals with genotype TT, while a smaller amount of intramuscular fat and more moisture in fat was revealed in heterozygotes. Conclusions. Genetic marker LEPR SNP NM001024587.1, p. 1987 C > T can be used in the marker-assisted selection to predict and improve the performance quality of the meat of pigs of Large White breed of the Ukrainian breeding. These results suggest that porcine leptin receptor gene controls the quality of fat comp- lex – inside muscles and in the dorsal part of the carcass.

ABSTRACT Objective: The purposes of this investigation were to determine the horizontal distances between the mandibular posterior teeth and the WALA ridge in a sample of Peruvians with normal occlusion and to compare them by tooth type, sex, arch side, and age groups. Methods: 65 dental casts of subjects with normal occlusion were collected. Posterior teeth, except for third molars, were evaluated. The horizontal distances between the occluso-gingival midpoints of the buccal surfaces (FA points) of each tooth and the WALA ridge were measured using a modified digital caliper. The values between each different tooth type within the sample were compared using the ANOVA and Scheffe tests, while comparisons by sex, arch side and age groups, using the Student’s t-test. Results: The mean distances in the sample was 0.96 mm for first premolars, 1.45 mm for second premolars, 2.12 mm for first molars and 2.55 mm for second molars. Statistically significant differences between each of the four tooth types were found. There were no significant differences found between sex, arch side and age groups. Conclusion: The horizontal distances between the mandibular posterior teeth and the WALA ridge increased progressively from the first premolars to the second molars in Peruvians with normal occlusion. The WALA ridge was a good landmark to evaluate the positions of posterior teeth in Peruvians with normal occlusion.

Topographic analysis of SVEPs in the medium frequencies range was performed in 30 migraineurs without aura, 20 migraineurs with aura and in 20 control subjects. The mean absolute power values of the fundamental component F1, the subharmonic F1/2 and the first harmonic F2, corrected by logarithmic transformation, were computed in each group and then compared using Student's t-test. The interhemispheric coherence of the F1 component was also evaluated. The 18, 21 and 27 Hz F1 components were increased in both migraineurs with and without aura, particularly in the temporo-parietal regions. The 24 Hz F1 component was augmented only in migraineurs without aura in the parieto-occipital regions in comparison with migraineurs with aura and controls. Migraine with aura patients had a reduced interhemispheric coherence mostly of 12 Hz and 15 Hz F1 components in frontal and temporo-parietal regions. Results of the study confirm abnormalities of SVEPs in migraineurs with and without aura. These consist of widespread increases of F1 components in the medium frequency range over the temporo-parietal regions.

Introduction: The changing proportion of older adults in society necessitates the need to determine the attitudes of health care professionals toward older adults. The purpose of this study was to explore attitudes of ageism and its correlates among health care professionals working with older adults. Method: This descriptive study was conducted in seven hospitals in five cities in Turkey. A total of 628 health care professionals participated in this study. The Fraboni Scale of Ageism (FSA) was used to collect data. Descriptive statistics, student’s t test, one-way analysis of variance and multivariate linear regression were used for data analysis. Results: The mean total score from the FSA was 56.9 ( SD = 8.0). Education (β = −.18, p < .001) and difficulty with the care of older adults (β = −.10, p < .05) were statistically significant predictors of the FSA score. Conclusions: The attitudes of health care professionals toward older adults were generally positive and affected by difficulty in providing care and the educational status of the health care professionals.

Studies were carried out on the main indicators of the chemical composition and physical properties of muskulus longissimus dorsi of pigs of different genotypes during hybridization. The indicators of the chemical composition and physical properties of muskulus longissimus dorsi were determined by conventional methods. The materials of experimental studies were processed using methods of variation statistics. According to the amount of moisture, no significant difference between the control and experimental groups was established. According to the amount of protein in meat, a tendency to a slight decrease, compared with the control group by 1.4 (group III) … 1.9 % (group II) was established. The use of boars of Poltava meat breed led to a decrease in intramuscular fat in descendants by 0.25 % compared with peers of a large white breed (P <0.95), and precocious meat - to a real increase of this indicator by 0.43 % at P> 0 , 95. A tendency towards an increase in the amount of tryptophan (by 0.04 ... 0.05) and oxyproline (by 0.004 ... 0.005) in the muscles of hybrid animals was revealed in comparison with peers of pure breed of large white breed. In terms of the biological usefulness of meat proteins, animals of group III were the best - in terms of the quality of the protein of the longest muscle of the back, their advantage over peers of group II was 0.07, and compared with purebred peers. Group I - 0.12 (p <0.95). It was found that with the same area of the meat spot both in purebred large white breeds of animals and hydrides of different genotypes, there is a tendency to increase the latter compared to the control in a humid place: with a «share» of «blood» ½ pm by 2.2 %, and with a «share» of blood ½ cm - 1.4 %. A tendency has been established to increase the pH value of the longest back muscle in animals with a «share» of blood of specialized meat breeds compared with a large white breed. In hybrid animals with a «share» of blood of Poltava meat and precocious meat breeds, there is a tendency to increase the pH value in comparison with the large white breed by 0.15 (2.8 %) and by 0.17 (3.1 %), i.e. the meat of hybrid pigs, the pH of which has a shift towards alkalinity due to less accumulation of lactic acid, has a worse preservation.
