TLDR High selenium levels in some areas cause health issues in cows and buffaloes, but blood tests remain normal.
The study conducted by D.K. Grewal and colleagues aimed to assess selenium levels and the effects of chronic selenosis in dairy animals in Punjab. It involved 112 crossbred cows and 187 buffaloes from 22 districts. Selenium levels were generally normal, except in Nawansheher and Hoshiarpur, where they were significantly high. Chronic selenosis manifested as poor health, emaciation, overgrown hooves with cracks, horn issues, alopecia, and hair loss, particularly on the trunk and tail. Additionally, affected animals showed decreased productivity and reproductive problems. Despite these clinical signs, there were no significant changes in hematological parameters like Hb, PCV, TLC, and TEC.
