Some economically useful signs of the pigs of a Large White breed in OOO “Rossyia”

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.

Hematological condition of breeding bulls after a long winter period of operation in the conditions of the Udmurt Republic

Purpose: to study hematological parameters of blood in bulls-producers of dairy breeds on the day of semen collection in the Udmurt Republic after a long winter period of operation, depending on the breeds, age and place of selection.Materials and methods. The work was performed at the Federal Research Center for Animal Husbandry named after Academy Member L. K. Ernst on the basis of AO "Udmurtplem" of the Udmurt Republic in the period from 2020 to 2021 on dairy bulls (n=20) aged 15-69 months, including a purebred Holstein breed of domestic selection (n=6), a Holstein black-and-white breed of European selection (the Netherlands, n=6), a black-and-white breed with blood transfusion on Holsteins on at the level of 94-98% (n=8). The content of white blood cells, red blood cells, hemoglobin and hematocrit, depending on age and breed, was studied on the ABC VET hematological analyzer on the day of taking the seed.Results. It was found that on average, in 20 bulls aged 15-69 months, the level of white blood cells was at the level of reference values of 8.8±0.25 x 109/l, red blood cells 10.3 x 1012/l, which is 50% more than the reference values. The concentration of hemoglobin is 128.0±2.92 g/l, hematocrit is on average 54.3%, with a norm of 24-46%. Breeding bulls at a reliable level, differing in age, showed that some animals had high indicators for red blood cells of 10.3±0.26 x 102, for hematocrit of 54.3% against 24-46% of reference values. Also, according to hematological indicators, there was a tendency to increase the concentration of hemoglobin and hematocrit in European-bred bulls.Conclusion. The study of the variability in hematological parameters depending on the selection showed that there is no significant difference in leukocytes and all indicators are at the level of reference values, and in erythrocytes more than 50% than the highest indicators. The highest hemoglobin values were at the level of 141-156 g/l instead of 128 g/l according to the highest reference values. Hematocrit also showed high max values in all groups in comparison with the reference values of 59-66% versus 46% in the norm. It is necessary when analyzing hematological blood parameters in addition to the average statistical indicators (M+m) also, monitor the variability (min-max) in order to obtain more objective information.

Results of researches of some rare species of raptors in the Nechkinsky National Park, Russia

This report presents the selected results of rare birds of prey studies in the Nechkinsky National Park (Udmurt Republic, Russia) 20 years after the first studies undertaken here by I.V. Karyakin in 1991–1996. The main efforts were directed to the study of the White-Tailed Eagle (Haliaeetus albicilla). At the same time, the identification of other rare species was made. The studies were carried out during short visits to the territory in 2016, 2017, 2019 and 2021. In the national park (NP), within the previously known breeding areas, 3 new nests were identified. They were 0.9–1.6 km displaced from the locations of the old nests found 20 years ago. A new breeding territory was found in the adjacent area near the border of the NP. Despite the incomplete study of the area, it is assumed to be 8-9 breeding areas in the national park, and 2–3 areas directly along its borders. The number of breeding pairs of eagles in comparison with the first half of the 1990s, according to the author, remains stable, and population increase, as happened on the Lower Kama in Tatarstan, has not been observed here. Eagles nest on large, old-growth pines and larch trees, with a distance of 130–530 m deep into the forest from the outer edge. The distance to the Kama River is 0.68 km on average (0.13–1.3 km, n=4). The minimum distance between the nearest neighbors in the Kama valley, unregulated by the reservoir, is currently 3.6 km, the average (n=3) – 3.9 km. Eagles breed occasionally on and off. No reproduction was recorded for 2–3 years. The period of egg laying extends for a month from the beginning of March to the beginning of April. The death of young birds on 6-10 kV power lines was revealed, as a result, the owners were obliged to equip the power lines with bird protection devices. White-Tailed Eagle nestlings were ringed with colored rings. Two repeated observations were obtained from the lower reaches of Kama. The Greater Spotted Eagle (Aquila clanga) continues to inhabit the National Park, which is confirmed by the meetings of adult birds. There has been two-three times population of the Peregrine Falcon (Falco peregrinus) in comparison with the first half of the 1990s. Breeding of this falcon was found on 2 territories with a distance of 16.5 km between them.

BIVALVE MOLLUSCS (BIVALVIA: UNIONIDAE, DREISSENIDAE, SPHAERIIDAE) OF UDMURTIA

The results of the studies of fauna of bivalve molluscs of Udmurt Republic are summarized. The annotated check-list of species of bivalve molluscs of the waterbodies of Udmurtiya is presented. After examination of own collections and critical assessment of published data, 26 species of bivalves from 74 localities (14 rivers, 2 reservoirs, 8 pounds and 2 oxbow lakes) have been included into the final list. In studied region 11 species of bivalves are recorded for the first time. From the zoogeographical point of view most species belong to the European-Siberian faunistic group (46 %), also a considerable part of fauna are European species (26,9% of overall species composition), which are located in the region at the Eastern border of the range.

GEOGRAPHICAL ANALYSIS OF THE ROAD TRAFFIC AND PARKING SPACE IN A LARGE CITY (ON THE EXAMPLE OF IZHEVSK)

One of the most important components of the territorial socio-economic complex of a city (especially a large one) is the system of urban passenger transport, which, in turn, consists of two subsystems: urban public transport and personal vehicles. In 2000-2020. many large and medium-sized cities in Russia are going through a period of active motorization. Izhevsk is no exception in this regard. The level of motorization of the population has been increasing in recent years both in the city and in the Udmurt Republic as a whole. There is a growing need to reduce the flow of personal vehicles towards more active use of public transport. Urban public transport (for all its significant scale) has, as a rule, 2-3 owners and therefore is largely manageable, which cannot be said about personal vehicles. It is not possible to force car owners to switch to public transport by order. But it is possible to create such conditions when the resident himself does not use his own car, but gives preference to public transport. For example, to organize the work of a single parking space, in which the placement of paid parking lots will make it unprofitable to visit many of the most attractive objects (especially in the central part of the city) by private vehicle. An example of such relevant work is shown in the proposed article. By order of the Administration of Izhevsk, the authors of the article have identified the most optimal locations for paid car parks. The choice was determined based on the results of step-by-step work to assess: the location of the potential of Izhevsk public transport, the intensity of traffic flows, the density of the population, the availability of existing parking areas, points of attraction for vehicles.

INFORMATION ABOUT FLORA OF THE UST-BELSKY NATURE PARK (UDMURT REPUBLIC)

The article presents the results of a long-term study of the indigenous flora of the Ust-Belsky Nature Park. A list of vascular plants is given. There are 588 plant species from 299 genera and 87 families. The territory of the park consists of 2 clusters. They are located on different banks of the Kama River. The list contains cluster information for each plant species. Only 477 plant species are common to the two clusters, while the remaining species are characteristic of individual sections of the natural park. There are 68 such types in cluster 1, and 43 in cluster 2. In the course of floristic studies in different years, the growth of 23 rare plant species listed in the Red Book of the Udmurt Republic was recorded on the territory of the Ust-Belsky Natural Park.

Mari of Udmurtia: Factors of Preserving Traditional Culture in Modern Conditions

The factors of preservation and intergenerational transmission of the traditional culture of the local group of Mari living in the territory of Udmurtia in a different ethnic environment is examined in the article. The source basis of the article was the field ethnographic materials collected in 2007 among the Mari of the Karakulinsky region of the Udmurt Republic and introduced into scientific circulation for the first time. The socio-economic situation of the respondents, the established mechanisms of adaptation to market relations, the preservation of traditional rituals and holidays, material and spiritual culture, the use of the native language, ethno-demographic processes, the activities of the Mari community to support ethnic culture are showed in the work. The author notes that the historically formed mechanism for ensuring the viability of the Mari society includes practices of demographic behavior, ethnic socialization of youth, reproduction of elements of spiritual and religious culture (prayers, family and calendar rituals, songs) and the material world (national costume, elements of architecture, musical instruments, national cuisine), the use of the Mari language. It has been proven that the ritual sphere of the Mari is undergoing transformations, but at the same time it continues to remain an inseparable part of the life of the people. In the course of the work, it was also revealed that the local group of Mari in modern conditions for self-preservation needs to constantly generate ethnic markers based on traditional culture. The key role in this is assigned to the village community, educational institutions and public organizations.
