Water samples from geothermal wells, springs, and surface waters in the region were analyzed for their chemical compositions, stable isotopes, and thermodynamic parameters. The results reveal that the geothermal waters in the Cuona-Woka Rift Zone are characterized by high concentrations of Na+, K+, SO4^2-, and Cl-, with moderate to high temperatures ranging from 60°C to 95°C. Geochemical modeling indicates that the geothermal waters are predominantly influenced by water-rock interaction processes, with the dissolution of silicate and carbonate minerals playing a major role. Isotopic analysis suggests a mixed origin of the geothermal waters, with contributions from both deep circulation and shallow recharge sources. This study provides a detailed understanding of the hydrochemical evolution of geothermal systems in the region and contributes to the broader understanding of geothermal energy resources in Tibet.</p> Dr. Tenzin L.

Aimed at exploring alternative feed additives, the research examines parameters such as weight gain, feed conversion ratio, and health indicators. Results indicate that the inclusion of these natural ingredients positively influences broiler growth rates and efficiency, suggesting their potential as viable supplements in poultry nutrition. This study contributes to the ongoing search for sustainable and effective nutritional strategies in poultry farming.</p> Raxmonov Farxod Xolbayevich, Eshimov Dusmurod, Nuriddinova Muxlisa Isomiddin qizi Copyright (c) 2025 Raxmonov Farxod Xolbayevich, Eshimov Dusmurod, Nuriddinova Muxlisa Isomiddin qizi https://creativecommons.org/licenses/by/4.0 https://www.theamericanjournals.com/index.php/tajiir/article/view/6276 Tue, 17 Jun 2025 00:00:00 +0000
