A Look Inside: Histopathological Examinations of Different Tail Tip Lesions in Dairy Cows

This study investigated tail tip lesions in 16 dairy cows, identifying 59 lesions including alopecia, annular constrictions, crusting, scaling, and swelling. Histopathological analysis revealed granulation tissue, purulent-necrotizing inflammation, and hyperkeratosis, suggesting that reduced blood flow, or ischemia, may cause these lesions, leading to necrosis. The study highlights the need for further research to confirm this hypothesis and explore the relationship between blood flow disturbances, feeding practices, and tail lesions in dairy cows. Despite the small sample size, the findings underscore the complexity of tail lesions and the necessity for detailed histopathological evaluation.
