Abstract: A total of 258 dairy cows, 52 downer cows (fresh calving, resistant to therapies cows) and 206 apparently healthy cows at 14 dairy farms were investigated. Blood serum parameters as aspartate transaminase (AST), creatinine kinase (CK), urea, creatine, cholesterol and the trace elements as manganese (Mn), cobalt (Co), selenium (Se), copper (Cu) and zinc (Zn) were analyzed. Glyphosate was also tested in urine and feeds using ELISA. Downer cows had significantly higher CK (p < 0.0001), AST (p < 0.0003) and urea levels (p < 0.05) and significantly lower cholesterol (p < 0.0001) than healthy cows. The Co and Mn levels were generally too low in all animals based on reference standards. Downer cows excrete significantly less glyphosate in urine than their healthy comparisons which could be due to kidney damage. Significantly reduced cholesterol concentrations in the downer cows indicate that vitamin D3 is deficient and, with both Mn and Co deficiency, would negatively influence cellular immunity and increase the risk for rhabdomyolysis.
