The Transbaikal horse belongs to the ancient aboriginal breeds and is most adapted to the local climatic conditions of dry, hot summers and frosty winters with little snow. It is unpretentious, hardy, and has a strong constitution. Research is aimed at preserving the breed’s genetic diversity by studying polymorphic variants of whey proteins, which are reliable genetic markers due to their codominant inheritance and comprehensive polymorphism. In the albumin locus, two alleles and three genotypes were identified. In the esterase locus, there are six alleles and 13 genotypes. In the transferrin locus - 7 alleles and 18 genotypes occur with different frequencies in the studied herds, which makes it possible to characterise their genotypic characteristics. Rarely encountered genotypes of the transferrin locus (less than 10 %) include eight genotypes: TFDD, TFDH, TFDI, TFDR, TFFI, TFFM, TFOR, TFR; esterase locus – 6 genotypes: EsGI, EsHH, EsHI, EsHO, EsII, EsGI. Based on the frequency of genotypes and alleles, homozygosity was calculated for each whey protein system and for the entire sample from the herd, the level of which ranges from 7.87 to 12.25 %. The overall homozygosity rate varies from 34.35 to 43.36 %, and the number of effective alleles (Na) in all herds is almost the same (2.30–2.91). Genetic variability ranges from 56.96–63.74 %. The index of gene similarity between herds is at the level of 0.8439–0.9058. The analysed herds form two subclusters: the first includes horses from the APC (Agricultural Production Cooperative) Livestock Breeding Farm named after. Kalinin and SPK “Rassvet”. In the second - animals from APC (Agricultural Production Cooperative) “Livestock Breeding Farm “Rodina” and AC (Agricultural Cooperative) “Taptanay”.","PeriodicalId":124451,"journal":{"name":"Bulletin of NSAU (Novosibirsk State Agrarian University)","volume":"18 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140506086","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}

Calcium concentration in wool was determined by atomic emission and mass spectrometry (AES–ICP and MS–ICP). According to the results of this analysis and comparison with previously developed reference intervals, we formed four groups of sires: I – level of Ca concentration less than 25th percentile, II and IV – within 25–75th percentile (physiological norm: 1597–2926 mg/kg) and III – more than 75th percentile. As a result of this distribution, the Ca concentration in the wool of animals of Group II was higher by 75.9 % compared to Group I; in turn, individuals of Group IV exceeded Group III – by 27.9 %. According to the results of semen quality characteristics evaluation, it was found that in the group of sires with Ca level within the previously developed reference intervals, the concentration of spermatozoa was higher by 15.3 % and their activity – by 0.17 points in fresh semen in comparison with the group with its reduced level (below the 25th percentile). High Ca content (above the 75th percentile) in wool contributed to a 9.0 % decrease in the concentration of spermatozoa compared to its average values. Thus, the calcium concentration, assessed by its level in the fur, affects the concentration and activity of sperm. It is necessary to evaluate it to improve the quality characteristics of sperm systematically.","PeriodicalId":124451,"journal":{"name":"Bulletin of NSAU (Novosibirsk State Agrarian University)","volume":" 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139620035","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}

The impact of maternal genotype on the concentration and variability of triiodothyronine in complete siblings of Landrace pigs was studied. For the study, blood serum samples were taken from 33 pigs using the vacuum method from the jugular vein. Blood samples were taken according to generally accepted practices. The studies were carried out in the laboratory of the biochemistry of the Novosibirsk State Agrarian University using the technique of competitive enzyme immunoassay with a set of reagents “Steroid ELISA-triiodothyronine” to quantify the concentration of triiodothyronine in blood serum. Enzyme immunoassay was performed on a Thermo Scientific Multiskan FC analyser. In pig breeding, the content of heavy metals in water, soil, feed, organs and tissues was constantly monitored. The concentration of chemical elements did not exceed the MPC level. Statistical processing of experimental data was carried out using standard methods of descriptive statistics and the statistical programming language or data analysis environment RStudio (using the functions: descrstats, summary, sd, read.table, write. table, aes). The strength of the influence of the genotype of mothers of the Landrace breed on the triiodothyronine content in complete siblings in the conditions of Western Siberia was established, which amounted to 4.6 %. In some mothers’ offspring, the triiodothyronine level was 1.9 and 1.8 times higher than in others. Two clusters of mothers were identified according to the concentration of triiodothyronine in complete siblings, which included three groups of mothers with an average level of 2.26 nmol/l and five groups with the attention of 1.30 nmol/l. The reference limits of the triiodothyronine level in Landrace pigs in the conditions of Western Siberia were established.","PeriodicalId":124451,"journal":{"name":"Bulletin of NSAU (Novosibirsk State Agrarian University)","volume":" 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139618330","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}

The maximum effect was obtained in the 3rd experimental group. The absolute increase in body weight of animals in this group significantly exceeded the control indicator - by 16.92 %. Thus, sequential separate feeding of thyme extract and probiotics to calves had a more pronounced positive effect on their growth. The improvement in growth rates of calves in the experimental groups can be explained by the normalisation of the composition of the intestinal microflora under the influence of the probiotic drug SBT-Lacto and the activation of digestive processes by substances contained in the thyme extract. A synergistic effect was obtained with the combined sequential use of these factors.","PeriodicalId":124451,"journal":{"name":"Bulletin of NSAU (Novosibirsk State Agrarian University)","volume":" 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139620131","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}

In affected birds, inflammatory changes were observed in the larynx, upper part of the trachea and infraorbital sinuses, and fibrin clots were observed in the respiratory sacs. Pathological material was subcultured in brain heart broth in the presence of antibiotics. Analysis of subcellular localisation of the OR77 protein was carried out using the SignalP-6.0 method. The immune epitope database (IEDB) was used to search for B-dependent epitopes of the OR77 gene. Primers for cloning were designed, and cloning regions of the OR77 gene containing B-dependent epitopes were simulated by ligating BamHI and HindIII into the polylinker of the shuttle vector pBE-S. Experiments were carried out to clone the active epitope sequence of the O. rhinotracheale OR77 protein in Bacillus subtilis and use it orally to identify immune activity and other possible adverse reactions. Nucleotide sequence analysis was performed using the UniproUGENEv program. The amplification procedure was carried out.

The relevance and problems of their use are noted. Alternative strategies for determining the resource potential of honey-bearing lands are shown. Scientific methods of identifying honey plants are described: the study of vegetation, analysis of the chemical composition of honey and its properties, the use of drones to survey honey grounds, and the use of artificial intelligence to process large amounts of data about honey grounds. GPS (global positioning system) technologies, which allow accurate geospatial mapping of homelands, are currently the most widespread. The identification of honey plants to improve the food supply is carried out by various methods: floral analysis of vegetation, pollen analysis, informational analysis of vegetation, and observation of the behaviour of bees in hives. New techniques for determining the land’s honey reserves and the flowering intensity of honey plants are presented: collecting nectar samples and sugar content in nectar, which helps collect data on nectar productivity and nectar quality with greater accuracy and efficiency. RFID tags are widely used for producing and managing honey stocks, monitoring the condition of hives, and determining bee colonies’ productivity. Thanks to advances in technology and scientific research, many new approaches allow for more accurate and efficient selection of resource aspects of honey lands.","PeriodicalId":124451,"journal":{"name":"Bulletin of NSAU (Novosibirsk State Agrarian University)","volume":" 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139619033","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}

With the participation of the People’s Commissariat of Agriculture and its people’s commissars - V. G. Yakovenko and A. P. Smirnova. An explanation is given for revising the Bolshevik model of Russian development in 1921, expressed in the transition to the NEP as a policy of partial “retreat to state capitalism.” Economic priorities and the main elements of the new agricultural policy are noted: allowing trade and financial freedom for peasants, restoring money circulation, diversity of forms of land use in the countryside, renting land, and using hired labour while maintaining a state monopoly on land. In the context of the ongoing transformations, the participation of the People’s Commissars of Agriculture and their role and influence in restoring Russian agriculture in the search for effective ways to develop the industry is considered. The most important facts of the personal biography of the People’s Commissars are reproduced. Against the backdrop of the consistent implementation of NEP in agriculture, there are also relapses from the Civil War era in the form of the final destruction of large landowner farms. Despite this, on the eve of the completion of the restoration process and the victory of the collectivisation course, the People’s Commissariat of Agriculture supported state support for individual solid farms and their cooperation. It advocated the exclusion of administrative measures concerning the peasantry.","PeriodicalId":124451,"journal":{"name":"Bulletin of NSAU (Novosibirsk State Agrarian University)","volume":" 28","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139619132","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}

Histological study of such internal organs as the liver, kidneys and spleen was carried out using the generally accepted method. As a result of the analyses, it was established that a characteristic feature of the pathomorphological manifestation of aspergillosis was a topical lesion of the respiratory system with the formation of multiple tumour-like foci of two types in the lungs anddestructive changes in the structure of the tissue of the liver, kidneys and spleen. Congestive venous hyperemia is expressed in all organs, which indicates chronic heart failure.

Data processing was done using Microsoft Office Excel and the R programming language in the data analysis environment RStudio version 2023.03.1 (RStudio, PBC). In most cases, the distribution did not correspond to normal, and the variances were not homogeneous. Based on the average value and median, a descending ranked series of copper content in tissue was established: cattle < yaks < sheep < pigs, in numerical terms based on the median: 1.57: 1.29: 1.02: 1.0. The medians for copper in cattle, yaks, sheep and pigs were 1.40; 1.15; 0.024; 0.91; 0.89 mg/kg, respectively, reference intervals are 0.40–2.13, 0.30–2.16, 0.39–1.43 and 0.28–1.47 mg/kg. The most significant range of variability,based on the standard deviation and the ratio of extreme variants, is characteristic of cattle. Based on the Kruskal-Walli’s test, muscle copper accumulation differed significantly between species (H = 18.277, df = 3, p < 0.001). Pairwise comparison showed significant differences in the pairs “cattle – pigs”, “cattle – sheep” and “pigs – yaks”. Two clusters were identified based on the similarity of copper accumulation: cattle - yaks and sheep - pigs.
