Meconium was present on the fleece of 114 newborn lambs in sixty-two per cent of the cases. It was observed in forty per cent of the firstlings of primiparae, whereas the highest proportion (eighty-two per cent) was seen in the group of the lambs of pluriparous ewes, which were born later. A short normal gestation period (less than 144 days), a low birth-weight (less than 4.0 kg.) and a short period of parturition appear to result in a reduced incidence of the presence of meconium.
