Abstract

Cattle producers have commonly supplemented trace elements to prevent deficiencies. The beef cow, primarily grazing forage or fed harvested forage, may be able to store adequate amounts of trace elements in the liver during periods of excess availability to maintain homeostasis during periods of marginal availability. Therefore, the objective of this study was to determine the seasonal effects on trace element status of multiparous cows in the absence of supplementation. Trace element concentrations in the liver biopsy were compared with serum concentrations removed at the same time.
