A CAREFUL CONSIDERATION of this parasite-control 
calendar may save you time and money, may help to 
save your livestock, and may even save your life. It gives 
timely warnings as to seasonal troubles from parasites and 
suggests ways and means of avoiding or controlling them. 
More detailed information may be obtained, on request, from 
the United States Department of Agriculture. 
The year-round suggestions at the end of this publication 
should be kept in mind as practical measures for preventing 
losses and increasing your income from livestock. 
The time arrangement in this calendar is based on conditions 
in the East, Middle West, North, and in the Rocky Mountain 
region of the United States. It is not so definitely applicable 
to conditions in the South, Southwest, and the Pacific coast. 
However, the control measures noted are generally applicable, 
and more precise information will be found in the various publi- 
cations mentioned here.
