Smith, R. E.
MetadataShow full item record
A disorder of cattle, which has been reported to be caused by excessive amounts of molybdenum in forage, occurs in the southwestern portion of the Swan River Valley of Manitoba. Field and laboratory investigations, herein reported, indicate; that molybdenum in quantities toxic to cattle is contained in forage; that the minute quantities of molybdenum contained in the water supply has no contributing effect on the disorders encountered; that the levels of molybdenum in soils of the affected area are relatively high in molybdenum; and that Thunder Hill, an outlier of Porcupine Mountain might contain the source of the element.
