Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.This research was conducted to identify genetic polymorphisms of the GNRHR gene on Isfahan native hen traits and their relationship with production traits. For this purpose, blood was taken, DNA was extracted, the target fragment was amplified and directly sequenced, and finally it was blasted with the reference gene in NCBI.

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.Natural eggshell sanitation using thyme essential oil reduced microbial contamination and lipid peroxidation while improving embryo viability and hatchability in stored broiler breeder fertile eggs. These findings support thyme essential oil as a promising residue‐free alternative for hatchery egg sanitation.

Spectromicroscopy Analysis of Chicken Egg Shells
X-Ray Spectrometry, Volume 55, Issue 4, Page 587-596, July/August 2026.ABSTRACT Chicken egg shells, taken from farm and backyard eggs of different suppliers from different regions in Brazil were collected for chemical/structural analysis, in order to try to find if there is a relation between egg shells composition and the type of production (farm or backyard), the egg shell color and the region of production.

Journal of Animal Ecology, Volume 95, Issue 7, Page 1151-1162, July 2026.Predation increases close to habitat edges, but how animals cope with local predation variations remained poorly studied. In a mosaic landscape, lapwings were compensating for increased nest predation close to forests. They acted more aggressively towards an avian predator when nesting close to trees, but comparatively tamer against a mammal.
