Promising Direction: Use Of Insects As Raw Material For Chitosan Production
No full textThe article examines the possibility of using insects as an alternative source of chitosan. The chemical composition of insect exoskeletons, the main stages of the technological process for obtaining chitosan, and the advantages of this raw material in terms of sustainable development are described. It has been shown that insects can be considered as a promising and environmentally safe raw material base for the production of chitosan. Chitosan is a natural biopolymer with high biological activity and a wide range of practical application
Effects Of Chitosan And Whey Powder Supplementation On Mineral Metabolism And Digestive Enzyme Activity In Broiler Chicks: Evidence Synthesis And A Methodological Framework
No full textImproving feed efficiency while reducing reliance on antibiotic growth promoters remains a key challenge in modern broiler production. This paper synthesizes international and CIS literature on chitosan (a cationic biopolymer) and whey powder (a dairy by-product rich in high‑biological‑value proteins and bioactive peptides), focusing on two mechanistic endpoints: mineral metabolism (Ca, P, Mg) and digestive enzyme activity (amylase, lipase, protease). Using a scoping‑review approach, studies published between 2010 and 2026 were mapped across PubMed, Cambridge Core, MDPI, Google Scholar, and open regional databases. Data were extracted on dosage, duration, measurement protocols, and key zootechnical outcomes. The synthesis indicates that chitosan may modulate intestinal barrier integrity, microbiota balance, and mineral bioavailability through adsorption and ion‑exchange properties, whereas whey powder may support metabolic stability via high‑quality protein fractions and peptides, with downstream effects on gut morphology and nutrient utilization. Local studies from Uzbekistan report beneficial shifts in growth performance, mineral indicators, and bone‑related metrics when chitosan and whey are applied in combination. The paper proposes an evidence matrix, a conceptual mechanism model, and practical methodological recommendations for future controlled trials

Issues Of Ensuring Food Security Under Climate Change Conditions
No full textSharp climate changes pose serious risks such as reduced water resources, an increase in natural disasters, and a decline in agricultural productivity, which altogether hinder the sustainable development of our region. These consequences primarily have a negative impact on vulnerable segments of the populatio
The importance of pumpkin (Cucurbita L) in medicine and folk medicine
No full textPumpkin (Cucurbita L.) has long been recognized not only as a nutritional food source but also as a plant of significant medicinal value. This article explores the multifaceted importance of pumpkin in both modern medicine and traditional folk healing practices. Rich in bioactive compounds such as carotenoids, tocopherols, flavonoids, and essential fatty acids, pumpkin exhibits a range of therapeutic properties including antioxidant, anti-inflammatory, antimicrobial, and antidiabetic effects. Clinical studies and ethnobotanical records reveal its use in managing conditions such as diabetes mellitus, hypertension, intestinal parasites, and prostate disorders. Moreover, pumpkin seed oil has gained prominence in urology and dermatology due to its beneficial impact on benign prostatic hyperplasia and skin regeneration. In folk medicine, various cultures have utilized different parts of the pumpkin—seeds, pulp, and peel—for healing wounds, boosting immunity, and improving digestion. This article presents a comprehensive review of recent scientific findings and historical applications, emphasizing the plant’s role as a bridge between natural remedies and evidence-based medical interventions
Morphological and Morphogenetic Characteristics of Dark Gray Soils (in the Example of theBakhmal District, Jizzakh Region)
No full textThis study investigates the morphological and morphogenetic characteristics of dark gray soils developed under natural conditions in the Bakhmal district of the Jizzakh region, Uzbekistan. The research was conducted on uncultivated dryland dark gray soils formed on deluvial–proluvial and loess parent materials within a semi-arid climate and a complex geomorphological setting. Field investigations included the description of soil horizons, determination of humus horizon thickness, and analysis of carbonate accumulation patterns. Laboratory analysis complemented field data to assess the physical structure and textural composition of the profile

Based on the results of the study, samples of durum wheat with high productivity indicators were selecte
Mechanisms Of Adaptation Of Small Mammals In Natural Biotes
No full textThe article assesses the adaptation mechanisms of small mammals in the natural biota of the Southern Aral Sea region to environmental conditions. Small mammals are an indicator species that respond with sensitivity to environmental factors (temperature, humidity, soil properties, anthropogenic factors). Depending on environmental factors, adaptation mechanisms are formed in their population

Problems And Opportunities Of The Beekeeping System In Uzbekistan
No full textThis article explores the current status and development potential of beekeeping in Uzbekistan, focusing on its regional, climatic, and agro-economic dimensions. Beekeeping has gained strategic importance in the country, with the establishment of the “Uzbekistan Beekeepers Association” in 2017, which led to key reforms such as tax exemptions, soft loans (UZS 36 billion via Aloqabank), and technology introduction. In 2023, Uzbekistan produced 31,500 tons of honey a 16% increase from the previous year. Meanwhile, in 2020, production stood at 21,410 tons. However, average honey yield per hive remains low, below 20 k
