To assess morphological parameters of skin, as well as the commercial characteristics of the raw materials obtained, we formed three groups (one control and two experimental) of 3-month-old males (25 animals in each group) and females (50 animals in each group). Control … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 1 · 5 Feb 2022 · 6,507 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrevention of Heat Stress in Lactating CowsVladimir Zaitsev, Vasily Korotkiy, Nadezhda Bogolyubova et al.In summer, when the air temperature rises, dairy cattle are very susceptible to heat stress, which results in a significant decline in productivity. The goal of the study is to assess how a Coniferous Energy Supplement (CES) made from raw materials derived from forestry waste affects lactating cows' ruminal digestion, milk production, and quality in extreme temperatures. Two sets of … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 1 · 19 Dec 2023 · 5,113 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpatial-Dynamics of Trace Metals Accumulation and Physicochemical Characteristics in Ikpukulu-Ama Creeks, Rivers State, NigeriaDavies Ibienebo Chris, Khang Wen Goh, Davies Imachrist Ibienebo et al.The study examines the spatial-dynamics variability of water parameters and trace metal concentrations between January and June 2023 at the Ikpukulu-Ama sites of the Bonny River, Nigeria. Key parameters analyzed include temperature, salinity, pH, transparency, dissolved oxygen, and trace metals (Ni, Pb, Cd, Cu, Zn) across three sites. The highest temperature, 32.56°C, was recorded at Site 2, indicating potential thermal … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 29 Jul 2026 · 494 accessesView PDFCite
Research ArticleOpen accessIn the abstractChanges in the Composition and Diversity of Pasture Grass Due to the Influence of Grazing in the Steppe Zone of Northern KazakhstanAliya Baitelenova, Balzhan Akhylbekova, Meisam Zargar et al.Overgrazing poses a serious threat to the sustainability of steppe pasturelands in Northern Kazakhstan, where intensifying livestock pressure drives significant changes in vegetation composition, species diversity, and soil fertility. This study investigated the effects of grazing intensity on pasture vegetation and chestnut soil properties in the Zhaksyn district of the Akmola region. Field surveys were conducted in July-August 2024 using … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 31 Mar 2026 · 1,338 accessesView PDFCite

Research ArticleOpen accessIn the abstractA Hybrid Machine Learning Approach to Predictive Analytics in Precision Agriculture for Sustainable Crop OptimizationJignesh Kariya, Pankaj MudholkarDriven by data-enabled technologies, precision agriculture is evolving into an innovative way to increase agricultural productivity and sustainability. Conventional agricultural practices face several challenges, such as poor soil quality, inappropriate crop selection, improper resource utilization, and unpredictable climate conditions. To address these limitations, this paper proposes a hybrid machine learning framework for sustainable crop optimization and predictive analysis in precision … …Journal of Computer Science, Vol. 22, Issue 10 · 10 Oct 2026 · 865 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Water Bath Heating on Tannin Content and Quality Improvement Potential of Gambier (Uncaria gambir Roxb.)Daimon Syukri, Bastian Nova, Rina Yenrina et al.Gambir (Uncaria gambir Roxb.) is a source of natural phenolic compounds rich in catechins and tannins and has potential as a sustainable industrial raw material. During heating, phenolic compounds may undergo structural changes, including possible oxidation and polymerization, which can affect gambier quality beyond its catechin content. This study evaluated the effect of indirect heating duration using a water bath … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 23 Sep 2026 · 704 accessesView PDFCite
