Implementation of “Digitalization of Agriculture” program by 2021 will allow solving a number of problems existing in this industry (food security of the country, export potential increase, etc.) and creating a high-tech branch. One of the directions of “Digitalization of Agriculture” program at the regional level is “smart sectoral planning” which will allow optimizing farmer’s activities when making a decision under the conditions of limited time. Currently, digitalization of agriculture in our country is at a low level. There is a lack of scientific and practical knowledge on technologies and methods in this field, a low level of forecast prices for agricultural products, etc. Let us consider the issue of adaptive forecasting in agricultural sector. The real processes in this industry take place in changing conditions, so the economic system has to adapt to them. The model describing economic system behavior will constantly adapt to the economic process. Adaptive forecasting methods allow building a class of self-adjusting models of economic systems that are able to reflect dynamic, changing over time processes in regional agricultural sector, to highlight the most significant parameters and to give fairly accurate forecasts of processes in future. The goal of this paper is to study using of adaptive methods for forecasting in the agricultural sector of the region. Using the data on the agricultural sector efficiency in certain region (Lipetsk Region), we show the mechanism of action of naive, adaptive and rational expectations models. As economical time series, statistical data were used on agricultural sector efficiency in the Lipetsk region – profitability level, parameters for output technological efficiency. As a result of studying the mechanism of action of naive, adaptive and rational models, conclusions were drawn about the feasibility of the wide acceptance of adaptive method for forecasting in the agricultural sector of the region as one of the factors for digital agriculture development. Keywords—adaptive model, naive expectations model, rational model, profitability level of agricultural products, parameters of technological efficiency of agricultural production.","PeriodicalId":216563,"journal":{"name":"Proceedings of the International Scientific and Practical Conference “Digital agriculture - development strategy” (ISPC 2019)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114269573","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 purpose of this study was a comparative analysis of poliovulation induction results in donors received one or several FSH injections. Experimental animals (n = 256) in group I (n = 96) received injections of “FSH-super” drug eight times, every 12 hours for 4 days; in group II (n = 73) there was one injection of “FSH-super” combined with polyvinyl alcohol with a molecular weight of 15,000 Da; in group III (n = 87) there was one injection of “FSH-super” combined with polyethylene glycol with a molecular weight of 6,000 Da. The number of donor cows with positive response to hormonal treatment in groups I-III was similar: 94.8%, 95.9%, and 95.4%, respectively, what shows the effectiveness of one injection of long acting FSH. At the same time, group III (with polyethylene glycol as prolongator) was the leader in the effectiveness of induced poliovulation – here the highest ovarian poliovulatory reaction was obtained with the formation of 15.2 yellow bodies per one donor (in groups II and I – 14.0 and 10.5, respectively). The number of obtained proper embryos in group III was higher by 9.6% than in group II, and by 15.6% than in group I, while the number of degenerated embryos in group III was 2.5% less than in group II and 15.0% less than in group I. In group III, there were the highest level of ovum fertilization rate (82.2%), the largest number of excellentand good-quality embryos (optimal for cryopreservation) – 89.9%, and also, of embryos at the stages of late morula, early blastocyst and expanded blastocyst (optimal for transplantation) – 93.3%.

The causative agent is widely spread all over the world, including the Russian Federation. The main symptom of the disease is the malignant proliferation of cells of the hematopoietic organs with a violation of their maturation. Developing quantitative and qualitative disorders of the hematopoietic system are noted in the diseased organism. This paper presents data on the effects of leukemia virus on the process of hematopoiesis in cattle in the conditions of the Ural region. Infected animals of the Tyumen region were identified by serological studies (RID, ELISA) and molecular genetic studies (PCR) of isolates of bovine leukemia virus. The RFLP method established the predominant presence of the “Belgian genotype” in the samples. The env (glycoprotein envelope) gene of leukemia pathogen was sequenced. The immunehematological studies of cattle, infected with leukemia virus in the conditions of the Ural region, were conducted. The obtained data showed a significant increase in the number of leukocytes, lymphocytes in the blood of leukemic animals, a sharp decrease in the number of eosinophils, monocytes, CIC (circulating immune complexes), phagocytosis, T and B lymphocytes.
