In a study conducted by Krista McLennan at the University of Northampton, it was discovered that cows form close bonds with certain fellow cows, which can be considered their ‘best friends.’ During the experiment, heart rates and cortisol (a stress hormone) levels were measured in cows when they were with their preferred partner and when they were apart. Results showed that cows had lower heart rates and were noticeably less stressed when spending time with their favorite buddy compared to when they were isolated or paired with another cow. This discovery highlights the complex emotional life of cows, contrasting with the common perception of them as simple creatures. These findings have important implications for animal welfare in the farming industry, suggesting better herd management and possible reconsiderations for living conditions.
