Base-line survey of blood trace element status of 50 dairy herds in the south of Ireland in the spring and autumn of 1991


, : Base-line survey of blood trace element status of 50 dairy herds in the south of Ireland in the spring and autumn of 1991. Irish Veterinary Journal 47(3): 115-122

Blood samples were collected from approximately 10% to 16% of cows in each of 50 dairy herds during the spring (541/4839 cows) and the autumn (627/4711) of 1991 to determine the herd copper, selenium and iodine status. For each of the trace elements, the mean value for all of the samples collected in a herd was used to classify the status of the herd with regard to that element as very high, high, normal, marginal, low or very low.
