Description
Da-Hye Kim and co-authors published this study in 2023. It asks how cold housing affects laying hens: their egg output, egg quality, and signs of physical stress. Cold snaps are a routine management problem in poultry regions with hard winters.
Forty hens spent four weeks in chambers held at chilly or normal temperatures. The cold group ate more, gained weight, and converted feed less efficiently, though it laid comparably. Their skin ran cooler while core temperature held steady, showing the body defended its core first. Eggshells from cold hens showed deeper color. Stress chemistry in the yolk spiked briefly in the first week, then settled, and blood fats rose under cold. The authors conclude the cold disturbed fat metabolism and early antioxidant defenses without triggering a lasting stress response. Producers, they suggest, should watch feed costs and egg quality during cold spells.
