Genetic aspects of polledness in sheep (review)
Submitted by Гость (not verified) on Sun, 07/13/2025 - 22:08The analysis of the genetic mechanisms underlying the presence or absence of horns is of interest both for understanding evolutionary processes and for realizing the economic benefits of breeding polled animals. The creation of polled sheep breeds has become an important breeding goal in many countries with developed sheep breeding industries, as these breeds are more technologically efficient to manage and require less feed.
Use of streptomyces for biocontrol of pests and virus mitigation in tomatoes in arid zones
Submitted by Гость (not verified) on Sun, 07/13/2025 - 22:08The “greening” of crop production technologies is fundamental to the modern concept of phytosanitary optimization of agroecosystems. Environmentally friendly plant protection products based on actinobacteria, with their novel mechanisms of action and high physiological and biochemical potential, are of particular interest. While soil streptomyces are technologically scalable, have long shelf lives, and are field-friendly, their effectiveness can vary due to limited knowledge of the properties of introduced actinobacteria.
Introducing Viburnum opulus L. into the dendroflora of Arkhangelsk
Submitted by Гость (not verified) on Sun, 07/13/2025 - 22:08Viburnum is a valuable ornamental tree species in the urban flora of Arkhangelsk. It is characterized by rapid growth, resilience to urban environmental conditions, strong soil-protecting properties, and high ornamental value. Viburnum has proven successful in northern green spaces due to its high adaptive capacity. The purpose of the research is to study the biological, ecological, and phenological features of the growth and development of common viburnum ( Viburnum opulus L. ) in the conditions of introduction in Arkhangelsk. Viburnum opulus L.
Solutions for intestinal health: a new direction in feeding monogastric animals (review)
Submitted by Гость (not verified) on Sun, 07/13/2025 - 22:08Realizing the genetic potential of monogastric animals depends on a well-functioning gastrointestinal tract, which not only digests and absorbs nutrients but also protects against harmful microflora. This intestinal function is energetically expensive, requiring up to 40% of daily protein and energy intake to support rapid enterocyte turnover – these cells are replaced approximately every three days. This article reviews current perspectives on using probiotics, prebiotics, and butyric acid-based complexes in modern industrial pig and poultry farming.
Influence of sire genotype and cattle breed gene pool on sperm cryosurvival
Submitted by Гость (not verified) on Sun, 07/13/2025 - 22:08This study characterized sires of Red-and-White, Black-and-White, and Red Steppe cattle breeds at JSC Barnaul Bull Stud Enterprise (Altai Krai, Russia) in terms of sperm production quality and resistance to freezing. A total of 50,388 ejaculates were examined before cryopreservation, including 38,333 that were frozen. The influence of individual sires was assessed on 1,716 ejaculates. Sires of the Black-and-White breed had the highest rate (31%) of sperm culling before cryopreservation. This rate was 9–18.2 percentage points higher than sires of the other two breeds (p < 0.001).
Application of amino acids and algae-based fertilizers in floriculture
Submitted by Гость (not verified) on Sun, 07/13/2025 - 22:08The aim of the research is to study the effects of amino acid-based and seaweed-based fertilizers on the linear and physiological parameters of different garden iris varieties (Cherry Garden, Lace Caper, Pink Pincurls). The experiment utilized Beres brand preparations (BeresAminoComplex and Beres Super Extract of Seaweed).
Assessment of insect resistance in a spring wheat genetic collection
Submitted by Гость (not verified) on Sun, 07/13/2025 - 22:08Spring wheat is one of the most important food crops both in Russia and worldwide, occupying approximately 80 million hectares in developing countries. However, sap-sucking pests are significantly impacting spring wheat yield and quality. This highlights the importance of integrated pest management (IPM), a holistic approach combining preventive and curative measures. Host-plant resistance is a cornerstone strategy within IPM. This study assesses pest resistance levels in a spring wheat ( Triticum aestivum L. ) genetic collection.

Federal state information systems in Russian agriculture: problems of use and possible solutions
Submitted by Гость (not verified) on Sun, 07/13/2025 - 22:08Federal state information systems (FSIS) in Russian agriculture are a key result and driver of digital transformation within the industry. Considering practical application and user needs, FSIS can be improved based on the identified shortcomings experienced by agricultural producers. An online survey was conducted in the first half of 2024, gathering responses from 957 operating agricultural enterprises across all constituent entities of the Russian Federation. The survey focused on experiences using the systems and the problems encountered.
