20.500.12556/RUL-185478 Effects of selenium nanoparticles and chitosan on meat quality, lipid profile, tissue mineral content and tibial bone morphometry in heat stressed broilers Učinki nanodelcev selena in hitozana na kakovost mesa, lipidni profil, vsebnost mineralov v tkivih in morfometrijo golenice pri toplotno obremenjenih brojlerjih This study aimed to assess the effects of selenium and selenium nanoparticles with chitosan on broiler chickens during heat stress. In this study, total 336 chicks were raised. These birds were split into seven groups, each with six sets of eight birds, depending on the treatments they received. There were two control groups: one with the regular diet (negative control) and another with the regular diet plus heat stress (positive control) known as A and B Groups respectively. The remaining groups were as follows: Group-C (Basal diet+0.3mg/kg selenium), Group-D (Basal diet + 0.3mg/kg nano selenium + heat stress), Group-E (basal diet+300mg/kg chitosan+heat stress), Group-F (basal diet+0.3mg/kg selenium+300mg/kg chitosan+ heat stress) and Group-G (0.3mg nano selenium + 300mg/kg chitosan/+basal diet + heat stress). The various parameters were analyzed, including drip loss, cooking loss, lipid profiles, mineral content, and bone characteristics was significantly improved in Group G, receiving nano selenium and chitosan under heat stress. Moreover, Group G showed higher selenium, calcium, and phosphorus content in breast muscle tissue, along with tibial bone characteristics such as weight, length, wall thickness, density, and medullary canal diameter as compared to group-B. Although weight/length index showed no significant differences, Group G demonstrated the highest Tibiotarsal Index (TTI) and Robusticity Index (RI). These findings suggest the beneficial effects of nano selenium and chitosan supplementation, particularly evident under heat stress conditions. selenium nano-selenium chitosan muscle quality lipid status tibial bone broiler heat stress true false true Angleški jezik Slovenski jezik Članek v reviji 2026-08-06 13:04:57 2026-08-06 13:05:03 2026-08-07 04:08:23 0000-00-00 00:00:00 2025 0 0 Str. 177-187 iss. 3 Vol. 62 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-01-01 636.52/28:69.058.5:546.23 2385-8761 10.26873/SVR-2101-2024 285591299 effects.pdf effects.pdf 1 D926C65118DB68FC092D0768272A5545 7d7b975f46054d32f17fa5d994454503015418c2d4b6615bea0a4e0d5a0dded0 77d86c97-9186-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=244009 https://www.slovetres.si/index.php/SVR/article/view/2101/925 1 55854c95-9186-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=244008 Veterinarska fakulteta Slovenian veterinary research 0 0 0
