The article presents the results of monitoring bovine pneumoenteritis in the Republic of Belarus in 2024–2025, an analysis of the dynamics of pathogen circulation over the period 2020–2025, and an assessment of the economic efficiency of implementing domestic PCR test systems. A statistically significant trend towards an increase in the proportion of associative forms of infection caused by bovine viral diarrhea virus from 63 % to 77 % has been established (p<0,05). The high cost-effectiveness of the developed diagnostic tools is confirmed (economic benefit of 5,1 rubles per 1 ruble spent).
This article explores the role of bumblebees Bombus spp. as highly effective pollinators in agricultural ecosys- tems. It outlines morphological and behavioral characteristics that provide bumblebees with clear advantages over the honey bee Apis mellifera, including the ability to perform buzz pollination, forage in low temperatures and under re- duced light. The paper presents an overview of international practices in the use of bumblebees in agriculture (including the EU, Canada, Japan, and Ukraine), emphasizing their impact on crop yield and quality. The study also highlights key ecological threats such as neonicotinoid pesticides and climate change, and identifies measures aimed at bumblebee conservation under the conditions of Belarus. It was concluded that it is highly advisable to use bumblebees in protected and open ground.
The article presents the main studies of the effectiveness of the action of recombinant lactoferrin obtained from the milk of transgenic goats, with antibacterial substances. The results of the study of antimicrobial activity, antibacterial properties, the rate of formation of antibiotic resistance, bactericidal and bacteriostatic activity of recombinant lactoferrin and antibacterial substances.
This article presents a diagram of the application of an experimental repellent sample on livestock farms. The study concluded that the best response (92,65 %) after application of the experimental repellent sample was achieved in group 2 facilities, where treatment was administered twice daily, 7 days apart. In group 3, where treatment was administered twice daily, 14 days apart, the response was 91,26 %.
This article summarizes data from two experiments examining the effectiveness of ultraviolet irradiation on various developmental stages of the red fowl mite, Dermanyssus gallinae, using proprietary 120 W units.
The article presents experimental data on the development and evaluation of the effectiveness of decontamination schemes for transplanted cell cultures from Mollicutes class bacteria (mycoplasma and acholeplasma). The efficacy of three antimicrobial regimens, commercial Plasmocin and Plasmocure, as well as the combination of tylosin and doxycycline, was compared in mycoplasma-contaminated EPS and 3KG cell lines. The high efficiency of all schemes in their adaptation to specific cultivation conditions has been established. Mechanisms of action of applied antibiotics and their potential activity against mycoplasmas and acholeplasmas, considering common targets in prokaryotic cells, are considered. Principles and algorithm of actions for development of effective decontamination schemes are formulated.
Complex study of recombinant interferon influence on indicators of protein, nitrogen, energy and mineral metabolism in calves is carried out. Biochemical analysis of blood serum showed no statistically significant negative effect of interferon on the functional state of the liver and kidneys. It was found that its use in a dose of 1,0 ml/10,0 kg contributes to the normalization of initially disturbed carbohydrate, lipid and mineral metabolism. The results indicate the high metabolic safety of recombinant interferon for calves and justify the feasibility of its use in the prevention and therapy of viral diseases.
Environmental protection does not lose its relevance in agricultural production from year to year. Animal husbandry accounts for the greatest environmental burden on the environment. Farms and complexes increase the number of animals, which leads to an increase in the volume of waste from the livestock sector of agriculture and as a result, the problem of their disposal, storage and processing arises. Many agricultural organizations do not bother to process manure, but simply bring it to the fields. Such ac- tions can lead to further environmental pollution and can be harmful to human health, since any animal waste products can be infected with parasites, dangerous viruses and weed seeds. All of the above leads to the need for a set of measures to eliminate pests and diseases found in animal waste products. The article discusses manure processing methods that improve the nutritional properties of organic fertilizers and reduce the release of unpleasant odors and greenhouse gases into the atmosphere.
