Factors affecting the iron and manganese content of plants with special reference to herbage causing “Pining” and “Bush-sickness.”

Abstract

In the account of “Pining” in sheep given by McGowan(1) there are so many points of similarity, both in the symptoms and in the general environmental conditions under which the disease is developed, with the disease known in New Zealand as “Bush-sickness,” as to suggest that these two diseases may be of a similar nature.
