Summary

Use of preparations with beneficial microorganisms in rabbit farming”, doctoral thesis in veterinary medical sciences, Chișinău, 2021. Thesis structure: introduction, 4 chapters, general conclusions and recommendations, bibliography with 260 titles, 6 annexes, 123 pages of basic text, 35 figures, 34 tables. The obtained results are published in 14 scientific papers and a patent obtained. Keywords: beneficial microorganisms, microbiota, dysbiosis, microbiological research, biomass, Streptomyces levoris CNMN-Ac-01, probiotic EM-1®, rabbits, biochemical indicators, nutrient environment, gastrointestinal tract, morph productive indicators. Purpose of the research: evaluation of the impact of Streptomyces levoris CNMN-Ac- 01 biomass and probiotic EM-1® on the microbiota of the gastrointestinal tract, growth and development of domestic rabbits. Оbjectives of the research: obtaining biomass of Streptomyces levoris CNMN-Ac-01; inclusion of Streptomyces levoris CNMN-Ac-01 biomass in the recipe of granulated compound fodder and study of its microbiological composition; preparation of the working solution of the probiotic EM-1® and study of its microbiological composition; study of the influence of granulated combined fodder with and without the addition of Streptomyces levoris CNMN-Ac- 01 biomass and the working solution of the probiotic EM-1® on the microflora of the gastrointestinal tract, physiological condition and morph productive indicators of rabbits; calculation of the economic efficiency obtained as a result of the use of Streptomyces levoris CNMN-Ac-01 biomass and the probiotic EM-1® in rabbit breeding technology. Scientific novelty and originality: for the first time, under the conditions of the Republic of Moldova, it was studied the role of Streptomyces levoris CNMN-Ac-01 biomass and probiotic EM-1® on the legality of formation and regulation of gastrointestinal tract biocenosis at rabbits, health stimulation, animal breeding and development, the chemical quality of rabbit meat and the proposal of these preparations for implementation in rabbit farming. The obtained result, which contributes to solving an important scientific problem: the elaboration and scientific argumentation of two technologies of administration (in food or water) of preparations with beneficial microorganisms, in order to balance the intestinal micro flora and combat gastrointestinal diseases, optimize the physiological, hematological, biochemical, productive and economic indices in the growth of the rabbit youth. Theoretical significance: elaboration of a new concept in the regulation of digestion, growth and development of domestic rabbits through the use of beneficial microorganism preparations (biomass of Streptomyces levoris CNMN-Ac-01 and probiotic EM-1®) and the scientific argumentation of the perspective of their use in rabbit farming. Applicative value of the work: results in the use in rabbit of the biomass of Streptomyces levoris CNMN-Ac-01 and of the probiotic EM-1®, which ensures the increase of the economic efficiency of the branch. Implementation of scientific results: the results obtained were implemented within the vivarium within SPIBZVM – acts of implementation of 03.09.2018 and of 17.09.2018 and JSC „Eco-Fer-Mer” d. Anenii Noi, v. Maximovca - act of implementation of 20.11.2020.
