Description
Shahab Bahadoran, Saeed Hashemi, and Hossein Hassanpour study how heat and crowding harm meat chickens at the cell level, in a 2025 paper. Heat and tight housing are top stressors on broiler farms. Both can raise oxidative harm and may speed cell aging. The team tracked caps on chromosome ends, called telomeres, plus a guard protein group that tends them.
Birds were split into plain, hot, crowded, and hot-plus-crowded groups. Stress groups showed more oxidative harm and shorter telomeres. Growth lagged in the hot groups. Two guard genes rose in stress groups, most in crowded birds. The authors urge better farm care to cut this cell harm.
