Welcome to our new audio article from Ceva Sounds Ruminants. The topic of today is How temperature and humidity affect cattle feed intake. A content developed by Ana Sofia Santos (Head of Research and Innovation at FeedInov CoLAB).

Temperature and humidity have a direct and significant impact on cattle feed intake, which in turn affects animal welfare, productivity, and efficiency. This article explores the physiological responses of cattle to thermal stress, explaining how heat stress leads to reduced feed consumption due to metabolic heat production, while cold stress prompts increased intake to support thermoregulation. It emphasizes the role of the Temperature-Humidity Index (THI) as a valuable tool in identifying risk thresholds for heat stress and outlines key mitigation strategies, including diet adjustments and environmental modifications to maintain animal health and performance in both hot and cold climates.
