Urinary iodine concentrations were determined in 672 dairy cows of 22 herds. Less than 20 micrograms per L, 20 to 50 micrograms per L, 50 to 100 micrograms per L and more than 100 micrograms per L were found in 27.5, 24.6, 16.8, and 31.3% of the cows, respectively. In terms of the ICCIDD grading, moderate iodine deficiency was recorded in 68.9% and normal iodine intake in 31.3% of the cows. The mean urinary iodine concentrations were 94.8 micrograms per L at the peak of the lactation period (n… CONTINUE READING
