Mongolia is a country with rich natural resources, including more than 70 million domesticated animals. The livestock sector is the traditional economic sector of Mongolia, and it is a major food source of the nation. Currently, the country faces an overgrazing problem caused by an increase in the number of animals whereas rangeland carrying capacity is limited. Exporting more meat and other products of animal origin has the potential to reduce the livestock population to sustainable levels, reduce overgrazing pressure, and increase the country’s export income. Policies aimed at promoting animal product exports should take the comparative advantages of different types of products of animal origin into account in order to maximize their impact. This paper aims to provide science-based evidence to support such policies by investigating the comparative advantage of meat and other selected products of animal-origin using the revealed comparative advantage index. Official statistics for 81 products over nine years were used for the data analysis. The results suggest that Mongolia’s meat export policy should focus on large volumes and relatively lower processing level products in the short run and should shift to differentiated value-added products in the long run. We recommend that the Government of Mongolia improves its meat sector’s regulation and develops formal supply chains in order to effectively monitor food safety and create high-quality Mongolian brand products of animal origin.

Sheeppox and goatpox are caused by sheep pox virus (SPPV) and goat pox virus (GTPV), members of Capripoxvirus genus, Poxviridae family. SPPV and GTPV damage host animal’s wool and skin and reduce production of mutton and milk. Because of morbidity and mortality of the diseases, they bring huge economic burden to the country. Main goal was to compare Mongolian sheep pox, goat pox sequences with other strains that were registered in Genebank. In this study, two SPPV and two GTPV field strains from Mongolia and Perego M strain (Biocombinat SOI, Mongolia), Russian and Chinese alive vaccine strains were used. The common DNA extraction method was used and samples were amplified on a nested polymerase chain reaction (nested-PCR) which amplify the full p32 gene of Capripoxvirus. The primers were designed based on the conserved sequences just outside of the p32 gene of SPPV or GTPV. By applying this method to the sheep and goat samples, suspected with SPPV and GTPV infection in Mongolia, the nested-PCR products were obtained from all samples on the predicted size, and the presence of SPPV and GTPV were confirmed via full length sequence analysis of P32 gene. Sequence comparison was performed using the online BLAST program. Sequence identities of nucleotides were analyzed using MUSCLE algorithm. A phylogenetic tree derived from nucleotide sequences was constructed for the Capripoxvirus using the neighbor joining method of MEGA (version X) software. Based on the phylogenetic tree, the Mongolian sheep pox virus, 2017 clustered together with Zabaikalsk strain and Perego strain (Biocombinat SOI, Mongolia). The Mongolian sheep pox virus, 2015 was closer to Tunisian and Chinese Gansu, Shanxi province strains. Chinese vaccine strain AV41, sequenced in this study was clustered with EF522181.1 Chinese Goat pox vaccine strain but Russian sheep pox vaccine strain, sequenced in this study was close to Mongolian goat pox viruses, 2009. The present data provides theoretical references to improve the preventive and control strategy. Based on the phylogenetic tree that we made, we conclude that SPPV and GTPV sequences in Mongolia were closer to Chinese SPPV, GTPV sequences therefore they were most likely imported from China.

The main vital cereal crop in Mongolia is wheat (Triticum spp.). There are more than 10000 wheat varieties are released and registered in the world wheat atlas up to the date. Internationally, wheat varieties are identified by their genotypes. However, local wheat varieties are being identified only by its phenotypic traits in Mongolia. Not significant study was carried out on wheat varietal identification. In this study, we aim to differentiate widely planting 6 local wheat varieties Darkhan-34, Darkhan-131, Darkhan-144, Darkhan-166, Tsogt and Khalkh-gol-1 using PCR based common quality and disease 22 markers. As a result, 10 out of 22 markers were detected in all wheat varieties in distinct sizes, 8 markers detected otherwise and 4 markers was not detected at all. Thus, the ZSBy9 marker which is specific marker to distinguish Darkhan-144, ZSBy8 primer which is specific marker to distinguish Khalkh gol-1, GluA1c and GluB1 Bx642 markers those are specific markers to distinguish Tsogt variety from other studied varieties respectively.

Anthrax is a worldwide zoonosis in animals and human. In Mongolia, the confirmed case of anthrax outbreak is reported every year over the past decade. The prevention and control measure of animal anthrax is vaccination using spore of attenuated Sterne strain, but horse does not get vaccinated in Mongolia. In this study, we constructed the recombinant plasmid for over expression of anthrax protective antigen (PA)/GST fusion protein in pGEX-6P-1 vector and purified the recombinant PA (r-PA) using glutathione Sepharose column under native and denaturing conditions. Since both forms of r-PA were recognized by specific antibody against PA, ELISA system to detect antibody titer in vaccinated bovine serum was constructed. Total of 890 vaccinated cattle serum were collected from 178 cattle at 0, 3, 5, 8 and 12 months’ post vaccination. As negative control, 200 cattle serum from Umnugovi aimag were selected which does not have anthrax foci. All serum was tested by rPA indirect ELISA and, antibody to PA were detected in vaccinated cattle serum but were not detected in negative serum. Therefore, rPA should be used in as monitoring of the anthrax vaccination.

Due to the crop monoculture system which has been 60 years continuously played in a key role in the crop sector Mongolia, soil erosion and its fertility decline have been becoming one of the main pressing issues in all crop zones. The main solution of restoration of soil fertility in the steppe zone of Mongolia is not only to reduce bare fallow but also urgently need to apply green manure in all regions. Our study has focused on identifying the appropriate timing to cultivate green manure crops in the Eastern steppe region of Mongolia and to determine the convenient alternatives of crops with a high yield of biomass to use for green manure. We determined the most convenient time to use crop biomass for green manure is between 22-27th.July for the green manure crops cultivated on the 20th of May. For the crops cultivated on the 30th of May green manure time can be determined between 2-6th. August and for the crops cultivated on the 10th of June the convenient time would be between 10-13th.August. We prioritized the best option of the crop alternatives based on the 3 years’ average yield of green mass and concluded that field pea and oat mixture, Sudan grass, and fodder pea mixture can be one of the convenient options for green manure in the steppe zone of Mongolia. According to our study results, convenient alternatives with the highest root mass were yellow clover (27.5-60.5c/ha) and white lupine (27.5-61.4c/ha). In terms of biomass, the convenient alternatives with the highest biomass were the following crops planted on the 20th of May such as mixture of field pea and oat (82.5-112.2c/ha), fodder pea and Sudan grass (67.497.0c/ha), as well as Sudan grass (57.1-110.0c/ha. It is considered that in the steppe zone green manure crops can be used for green manure if the biomass of the crops can exceed 40c/ha. The appropriate timing of the planting period should not be later than the 30th of May.

Four strains of yeasts isolated from some mare’s fermented milk, whey and fruit were identified using their morphology, biochemistry and phylogenetic characteristics. These yeasts belonged to four genera viz: Candida (one strain), Pichia (one strain), Saccharomyces (one strain) and Kluyveromyces (one strain). The physiological and biochemical tests of the yeasts carried out showed all isolates to ferment glucose for their growth. All isolates showed elliptical to round spores. Pichia kudriavzevii was able to ferment xylose of the four isolates. The assimilation and fermentation of most sugars by the isolates was variable. The blast sequence query showed that Saccharomyces cerevisiae and Pichia kudriavzevii had maximum identity (100%) with the genomic DNA sequence of MON-21 and MON-22, respectively at both ITS. Isolate Candida boidinii MON-23 was 100% homologous to Candida boidinii 18S rRNA gene sequence. The blast sequence query showed that Kluyveromyces marxianus MON-24 has the maximum identity (99%) with the genomic DNA sequence of Kluyveromyces marxianus at ITS 1 and ITS 4 sequence with that in the Genbank Library Database. Using MEGA 7 software, the phylogenetic trees were constructed to determine the evolutionary relationship of newly identified yeasts from our experiment and previously published yeast species. The sequences of the yeasts were deposited in the National Center for Biotechnology Information (NCBI) database.

The Mongolian grasshopper component (foreign and Mongolian researchers) study was carried out in the period 1951 to 2019 years during 68 years the materials in main classification unit that is divided 2 periods which are good condition climate before 1990 year and changed climate. We have updated 3 families and 48 genus considering total 110 species of Mongolian orthoptera which was travelers, researchers and biology expeditions known 1951 to 1989 years materials. Also updated 2 families and 33 genus considering total 81 species grasshopper distribution of Mongolia because of tandem with the climate change 1995 to 2019 years. Summing up the results of the study conducted in the period from 1951 to 2019 years, it was known that 4 families and 50 genus considering total 135 species, were distributed in our country.

In the current context of climate change and with the intensification of soil erosion, its fertility is declining and the crop yields are being reduced, thus providing complete protection of the soil from wind erosion, increasing soil fertility, alternating crop yields, and seeding fertilizer fertilization in the field 2016-2018 service research. The yield of 1 ha of wheat per hectare was 0.08 t/ha due to the climatic conditions of the year, compared to the unpaved field in two-grain alternation. It was found that using fertilizer on a covered area, the yield can be increased by 0.73-0.93 t/ha or 0.14-0.34 t/ha by the unpaved area. The protein content of wheat cultivated in a two-sided alternation was significantly higher than the dose of full mineral fertilizer and the secondary dose of gluten was higher than the dose of other fertilizers. Increased wheat protein content, high dose of full mineral fertilizer (N60P45K30), and high gluten content (N40P30K20) were found in two-sided alternation in padded fields.

Baast, Zandraagombo Dovchin, Baatartsol Bumbaldai","doi":"10.5564/mjas.v29i1.1379","DOIUrl":"https://doi.org/10.5564/mjas.v29i1.1379","url":null,"abstract":"In the current context of climate change and with the intensification of soil erosion, its fertility is declining and the crop yields are being reduced, thus providing complete protection of the soil from wind erosion, increasing soil fertility, alternating crop yields, and seeding fertilizer fertilization in the field 2016-2018 service research. The yield of 1 ha of wheat per hectare was 0.08 t/ha due to the climatic conditions of the year, compared to the unpaved field in two-grain alternation. It was found that using fertilizer on a covered area, the yield can be increased by 0.73-0.93 t/ha or 0.14-0.34 t/ha by the unpaved area. The protein content of wheat cultivated in a two-sided alternation was significantly higher than the dose of full mineral fertilizer and the secondary dose of gluten was higher than the dose of other fertilizers. Increased wheat protein content, high dose of full mineral fertilizer (N60P45K30), and high gluten content (N40P30K20) were found in two-sided alternation in padded fields. \u0000Сүрлэн хучлага бүхий хоёр талбайт сэлгээнд тариалсан буудайн ургац, үрийн чанарт бордооны төрөл, тунгийн нөлөө \u0000Уур амьсгалын өөрчлөлт идэвхтэй явагдаж, хөрсний элэгдэл эвдрэл эрчимжихийн хэрээр түүний үржил шим доройтож, түүнээс хураан авч буй ургацын хэмжээ буурч буй өнөөгийн нөхцөлд талбайд сүрлэн хучлага үүсгэснээр хөрсийг салхины элэгдлээс бүрэн хамгаалах, хөрсний үржил шимийг нэмэгдүүлэх, сэлгээний таримлын ургац, үрийн чанарт тарилтын үеийн бордооны үйлчлэлийг судлах судалгааны ажлыг 2016-2018 онд хйиж гүйцэтгэв. Сүрлэн хучлага бүхий талбайн 1 га-ийн буудайн үрийн ургац нь тухайн жилийн цаг уурын нөхцлөөс шалтгаалан 2 талбайт сэлгээнд хучлагагүй талбайнхаас 0.16 т/га-аар, уг хучлагатай талбайд бордоо хэрэглэснээр ургацыг хучлагагүй талбайнхаас 0.14-0.58 т/га-аар нэмэгдүүлэх боломжтойг илрүүлэв. Хучлагатай тариалангийн хоёр талбайт сэлгээнд тариалсан буудайн үрийн уургийн агуулалт, эрдэс бүрэн бордооны өндөр (N60P45K30) тун, цавуулгийн агуулалт дунд (N40P30K20) тунгийн үйлчлэлд илүү нэмэгдэж байна. Иймээс сүрлэн хучлага бүхий технолги мөрдсөн нөхцөлд бордооны төрөл, тунгийн судалгааг технологийн дагуу хэрэглэх зайлшгүй шаардлагатай болох нь харагдаж байна. \u0000 Түлхүүр үг: эрдэс, гумат, ризобактери, уураг, цавуулаг \u0000 ","PeriodicalId":18941,"journal":{"name":"Mongolian Journal of Agricultural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89936466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
