Генетичний поліморфізм свиней породи ландрас на основі мікросателітних маркерів

The aim of this study was to analyze the genetic variability and population structure of the Landrace population by using 12 microsatellite markers. A total of 90 pigs representing one commercial breed (Landrace) were sampled. Twelve microsatellite loci (SW24, S0155, SW72, SW951, S0386, S0355, SW240, SW857, S0101, SW936 SW911 and S0228) were selected and belong to the list of microsatellite markers recommended by FAO/ISAG. GenAIEx software was used to calculate the allele frequencies, effective number of alleles (Ae), observed (Ho) and expected (He) heterozygosity, within-population inbreeding estimate (Fis), Shannon’s information index (ISh). Overall allele frequency values ranged from 0.006 to 0.9333 (at allele SW951120). The number of observed alleles (Na) detected ranged from 5 (S0155 and SW911) to 13 (SW72), with an overall mean of 9.00 ± 0.80 and a total of 108 alleles were observed at these loci. However, the effective number of alleles (Ae) ranged from 1.57 (SW951) to 5.49 (SW240) with a mean of 3.29 ± 0.33. Shannon’s information index (ISh) which measures the level of diversity, was sufficiently high – from 0.79 (for SW951) to 2.01 (for SW240) – with a mean of 1.43 ± 0.09. The overall means for observed (Ho) and expected (He) heterozygosities were 0.578 ± 0.009 and 0.662 ± 0.004, respectively, which ranged from 0.307 (SW951) to 0.814 (SW857) and 0.361 (SW951) to 0.818 (SW240), respectively. Of the 12 microsatellites analyzed using Fisher’s exact test, 50% were in Hardy-Weinberg equilibrium, and 6 were out of equilibrium (P < 0.05). Three mutation models namely, infinite allele model (I.A.M.), two phase model (T.P.M.), stepwise mutation model (S.M.M.) were estimated using the BOTTLENECK software. The results are indicated that the Landrace pig population is non-bottlenecked and remained at mutation-drift equilibrium. The study stands first in genetic characterization of the Ukrainian Landrace pig population through microsatellite markers. The various parameters and values used to quantify genetic variability, such as the high mean (and effective) number of alleles and the expected and observed heterozygosities, indicated high genetic variability in the Ukrainian Landrace pigs. The population has not undergone any recent and/or sudden reduction in the effective population size and remained at mutation-drift equilibrium.Мета цього дослідження полягала в тому, щоб проаналізувати генетичну мінливість і структуру популяції свиней породи ландрас з використанням 12 мікросателітних локусів. Всього було досліджено 90 свиней, які представляють одну комерційну породу (ландрас). Було обрано 12 мікросателітних локусів (SW24, S0155, SW72, SW951, S0386, S0355, SW240, SW857, S0101, SW936 SW911 і S0228), які входять до списку мікросателітних маркерів, рекомендованих ФАО / ISAG. Для розрахунку частот алелей, ефективного числа алелей (Ae), фактичної (Ho) і очікуваної (He) гетерозиготності, оцінки інбридингу (Fis), інформаційного індексу Шеннона (ISh). використовувалося програмне забезпечення GenAIEx. В цілому, частота алелей варіювала від 0,006 до 0,9333 (для алелі SW951120). Число алелей (Na) варіювало від 5 (S0155 і SW911) до 13 (SW72) із середнім значенням 9,00 ± 0,80. Загалом для цих локусів було виявлено108 алелей. Однак ефективне число алелей (Ae) варіювало від 1,57 (SW951) до 5,49 (SW240) із середнім значенням 3,29 ± 0,33. Інформаційний індекс Шеннона (ISh), який свідчить про рівень різноманітності, був досить високим – від 0,79 (для SW951) до 2,01 (для SW240) – із середнім значенням 1,43 ± 0,09. Середні значення фактичної (Ho) та очікуваної (He) гетерозиготності становили 0,578 ± 0,009 і 0,662 ± 0,004, відповідно і варіювали від 0,307 (SW951) до 0,814 (SW857) і від 0,361 (SW951) до 0,818 (SW240) відповідно. Із 12 локусів мікросателітів, проаналізованих з використанням точного тесту Фішера, 50% перебували в стані рівноваги Харді-Вайнберга, а решта – відхилялися від нього (Р < 0,05). З використанням програмного забезпечення BOTTLENECK оцінювалися три мутаційні моделі, а саме: модель нескінченного числа алелей (I.A.M.), двохфазна модель (T.P.M.), модель покрокової мутації (S.M.M.). Результати свідчать, що для популяції свиней породи ландрас не відзначено bottleneck-ефекту і вона перебувала в стані рівноваги між мутаційним процесом і дрейфом генів. У дослідженні вперше наведена генетична характеристика української популяції свиней породи ландрас з використанням поліморфізму мікросателітних локусів. Різні параметри, які використовуються для кількісної оцінки генетичної мінливості, дають високі оцінки середнього (і ефективного) числа алелей, очікуваної і фактичної гетерозиготності, що вказує на високу генетичну мінливість української популяції свиней породи ландрас. Популяція не зазнала будь-яких недавніх і/або раптових скорочень ефективної чисельності і залишалася в стані рівноваги між мутаційним процесом і дрейфом генів.&nbsp

Analysis of the spatial distribution of the ecological niche of the land snail Brephulopsis cylindrica (Stylommatophora, Enidae) in technosols

The aim of our work is to describe the ecological niche of the land snail Brephulopsis cylindrica (Menke, 1828) in terms of the edaphic properties and properties of the vegetation cover and to show the spatial features of the variation of the habitat preference index within the artificial soil body – technosols (soddy-lithogenic soils on loess-like clays) using the ecological niche factor analysis (ENFA). The research was carried out at the Research Centre of the Dnipro Agrarian and Economic University in Pokrov. Sampling was carried out on a variant of artificial soil (technozems) formed on loess-like clays. The test site where the sampling was conducted consists of 7 transects of 15 samples each. Test points form a regular grid with a mesh size of 3 m. Soil mechanical impedance, aggregate-size distribution, soil electrical conductivity, vegetation physiognomic characteristics, and Didukh phytoindication scales were used as ecogeographic predictors of the mollusc’s ecological niche properties. Phytoindication assessment indicates that the technosol ecological regimes are favourable for sub-mesophytes, hemi-hydrocontrastophiles, neutrophiles, semi-eutrophs. The test for statistical significance showed that an axis of marginality of the ecological niche of B. cylindrica and axes of specialization are significantly different from the random distribution. We found that the ecological niche of the mollusc is determined by both edaphic factors and ecological features of vegetation. The marginality of B. cylindrica ecological niche over the entire period of study is determined mainly by preferences for physiognomic vegetation types, higher values of the continentality and thermality regimes. Often greater content in the soil of aggregates 1–3 mm in size coincides with greater numbers of B. cylindrica individuals. Individuals of this species avoid physiognomic type III and areas with higher soil alkalinity and mineralization detected both by means of the phytoindication approach and soil electrical conductivity data. Ecological niche optima may be presented by integral variables such as marginality and specialization axes and plotted in geographic space. The spatial distribution of the B. cylindrica habitat suitability index (HSI) within the technosols is shown, which makes it possible to predict the optimal conditions for the existence of the species

Charm production nearby threshold in pA-interactions at 70 GeV

The results of the SERP-E-184 experiment at the U-70 accelerator (IHEP, Protvino) are presented. Interactions of the 70 GeV proton beam with C, Si and Pb targets were studied to detect decays of charmed $D^0$, $\overline D^0$, $D^+$, $D^-$ mesons and $\Lambda _c^+$ baryon near their production threshold. Measurements of lifetimes and masses are shown a good agreement with PDG data. The inclusive cross sections of charm production and their A-dependencies were obtained. The yields of these particles are compared with the theoretical predictions and the data of other experiments. The measured cross section of the total open charm production ($\sigma _{\mathrm {tot}}(c\overline c)$ = 7.1 $\pm$ 2.3(stat) $\pm$1.4(syst) $\mu$b/nucleon) at the collision c.m. energy $\sqrt {s}$ = 11.8 GeV is well above the QCD model predictions. The contributions of different species of charmed particles to the total cross section of the open charm production in proton-nucleus interactions vary with energy.Comment: 4 pages, 6 pages, 38th International Conference on High Energy Physics 3-10 August 2016, Chicago, US

Method of individual forecasting of sow reproductive performance on the basis of a non-linear canonical model of a random sequence

Improvement of sow reproductive performance is a key factor determining the efficiency of the pig production cycle and profitability of pork production. This article presents the solution of an important scientific and practical problem of individual forecasting of sow reproduction . The population used for the present study is from a pig farm managed by the Limited Liability Company (LLC) ‘Tavriys’kisvyni’ located in Skadovsky district (Kherson region, Ukraine). The experimental materials used for this study consisted of 100 inds. of productive parent sows of the Large White breed.The litter size traits – the total number of piglets born (TNB), number of piglets born alive (NBA) and number of weaned piglets (NW) – were monitored in the first eight parities over an eleven year period (2007–2017). The method of the forecasting of sow litter size is developed based on the non-linear canonical model of the random sequence of a litter size change. The proposed method allows us to take maximum account of stochastic peculiarities of sow reproductive performance and does not impose any restrictions on the random sequence of a litter size change (linearity, stationarity, Markov property, monotony, etc.). The block diagram of the algorithm presented in this work reflects the peculiarities of calculation of the parameters of a predictive model. The expression for the calculation of an extrapolation error allows us to estimate the necessary volume of a priori and a posteriori information for achieving the required quality of solving the forecasting problem. The results of the numerical experiment confirmed the high accuracy of the proposed method of forecasting of sow reproduction. The method offered by us almost doubles the accuracy of forecasting of sow litter size compared to the use of the Wiener and Kalman methods. Thus, average forecast error decreases across the range of features TNB (1.71), NBA (1.68) and NW (1.25 piglets). Apparently, this may reflect a higher level of manifestation of the genetically determined level of individual sow fertility at the moment of piglet weaning. The higher adequacy of the developed mathematical model with regard to NW can be also due to the fact that the relations between sow litter size in different farrowings primarily have a non-linear character, which is taken into maximum account in our offered model. Given non-linearity, on the other hand, turns out to be a significant factor determining a lower estimation of the repeatability value for NW compared to the estimations for TNB and NBA. The use of the developed method will help to improve the efficiency of pig farming
