From Cortisol to Comfort: Understanding Stress in Feedlots

When cattle enter the feedlot, they encounter big changes — transport, new pens, new diets, unfamiliar animals — and all of this creates stress. While short-term stress helps animals adapt, chronic or repeated stress can reduce feed intake, slow growth, weaken immunity, and increase the risk of respiratory disease. In this video, we explore: • What actually happens inside the animal’s body during stress • The role of the HPA axis and sympathetic nervous system • The difference between acute and chronic stress • Why cattle straight from auctions are more vulnerable • How heat, transport, mixing, and diet changes affect behaviour • Simple management tools to improve adaptation and performance • Why calmer animals = better welfare and better profit From cortisol spikes to feed intake and rumination time — understanding stress is key to successful feedlot performance. The calmer the transition, the stronger the animals. Because stress is unavoidable — but suffering is not. #FeedlotFarming #BeefProduction #LivestockManagement #AnimalHealth #RuminantNutrition #CattleHealth #FeedlotCattle #BeefCattle #HerdHealth #AnimalWelfare #StressManagement #BRD #TransitionNutrition #FarmManagement #AgriSA #SouthAfricanFarming #VeterinaryScience #LivestockPerformance
