Goat Population

In recent years, goat breeds with a dairy-meat-wool or combined productivity type, represented by local breeds that are bred mainly in the foothills and mountainous regions of the North Caucasus, Altai, Tyva and Khakassia, have become increasingly widespread in Russia. The Karachay goat population is the most interesting for research, since in their breeding was aimed at obtaining animals with a number of unique productive characteristics and capable of producing the required outputs under the harsh conditions of the mountain and foothill zones of the Caucasus. In view of the limited research on these animals, in particular their reproductive functions, the aim of this study was to investigate the natural implementation of the reproductive function of the Karachay goats in different geographical areas of breeding. There are slight differences in some parameters of Karachay goat reproduction in high mountain zone (from 2000 m a.s.l.) and middle mountain zone (1000–1500 m a.s.l.). An important conclusion is that the recognized low fertility of the Karachay goats is not genetically determined. Analyzing the number of ovulations and fresh yellow bodies in the ovaries by laparoscopy using Karl Storz (Germany) endoscopic equipment, the authors found a potential fecundity of 3.1 (2.8 to 3.4).

The issue of the use of mineral forms of nitrogen for legumes is still a source of debate among scientists. Under the environmental conditions of the foothill zone of RNO-Alania, the field experiments were laid to study the activity of the symbiotic system and the productivity of the alfalfa depending on the type of nitrogen nutrition and the presence of a virulent active strain of rhizobia. The research was carried out in 2017– 2019. Soil – chernozems leached. Objects: crops of Medicago varia Mart.; industrial strain of rhizotorphin 425a; inoculum of high-mountain strains of nodule bacteria; starting doses of nitrogen fertilizers. The dimensions of the symbiotic apparatus were studied according to the G.S. Posypanov method. The specific activity of symbiosis was 4.2 to 9.0 mg/kg. The maximum amount of air nitrogen (456.1 kg/ha) for three years of experiments was fixed by the symbiotic system of alfalfa in the variant with pre-sowing seed inoculation with high-mountain strains of nodule bacteria. This indicates their higher activity and competitiveness compared to the industrial strain of rhizotorphin 425a and indigenous strains of rhizobia from the pre-mountain zone of RNO-Alania. Mineral forms of nitrogen significantly inhibited the activity of the symbiotic system. As a result, the amount of fixed nitrogen decreased by 3.5–9.0 %. In the pre-mountain zone, under natural conditions, the growth and development of plants were provided with atmospheric nitrogen by 66 %, the rest of the need for the element (34 %) they satisfied with soil nitrogen. The maximum involvement of molecular nitrogen of the atmosphere in the biological cycle was distinguished by the variant with pre-sowing inoculation of seeds by virulent active strains of rhizobia, in which the share of air nitrogen participation in plant nutrition averaged 71–73 % over the three years of research.

Zones And Subzones

Rangeland deterioration and restoration management has been one of the prominent issues. The present study focuses on the composition, cover, and yields accumulation of rangeland plant species from different ecological zones and subzones. Pasture yield in Mongolia varies in ecological zones and subzones (p≥0.001), so 39 sheep, during the summer, comfortably graze in one-hectare area in high mountain zone, - 72 in forest steppe, 21 in steppe and 13 in arid steppe area respectively. Whereas types and cover of plant species in high mountain rangelands are more than other areas, yield accumulation is most in forest steppe. The impact of climate change has dramatically increased recent years, considerably affecting on pasture plant cover and yield. During a dry season or period of drought, amount of yield reduces 40% in high mountain zone; 49% in forest steppe, 52% in semi-arid steppe and 55% in arid steppe. Since rangeland productivity varies due to the nature and climate in the ecological zones and subzones, pasture shall be utilized under appropriate policy that regulates this depending on its capacity, resource and natural and climate feature of area.

Main Attraction

The "Sustainable Development Complex Policy in Mongolia 2030" document represents the "Nomadic Culture" as a tourist hub, indicating that nomadic lifestyle is the main attraction in tourism. One of the main issues of concern for tourism in Mongolia is to focus on the herder lifestyle that differs from each other depending on natural zones. Therefore, we aim to study the different types of farming and lifestyle in such regions, as the Gobi, arid steppe, steppe, forest steppe and high mountain zone and determine which types of tourism are more convenient in each region.
