TLDR High selenium levels in some areas cause health issues in cows and buffaloes, but blood tests remain normal.
The study investigated selenium levels in the animal-plant system in Punjab, focusing on chronic selenosis in 112 crossbred cows and 187 buffaloes across 22 districts. Selenium levels were normal in 20 districts but significantly high in Nawansheher and Hoshiarpur. Chronic selenosis symptoms included poor health, emaciation, overgrown hooves with cracks, horn issues, alopecia, hair loss, decreased productivity, and reproductive problems. Despite these clinical signs, there were no significant changes in hematological parameters like Hb, PCV, TLC, and TEC.
