No consistent pattern of plasma zinc concentrations was observed in the peri-parturient period in 17 ewes, although large transitory depressions of plasma zinc levels were recorded in five ewes including one non-pregnant control. Sheep with dystocia did not exhibit a fall in plasma zinc similar to that recorded in cattle.
