Look for signs of liver flukes. 
Dip sheep to kill ticks. 
Control fleas on household pets. 
Along the Gulf and Pacific coasts and the adjoining basins of 
their tributary rivers, look out for evidence of liver flukes in sheep 
and calves. The animals may improve and become fatter in the 
first stages, but later they will begin to get thin and show a persistent 
diarrhea. On post-mortem the liver will be found to be soft, easily 
broken up, and full of flukes, which are flat, leaflike worms (fig. 12) 
an inch or so long. Call in your veterinarian and have him treat 
the animals with small doses of carbon tetrachloride. Consult 
Farmers’ Bulletin No. 1330 (8). 
Fic. 12.—The Fic. 13.—The sheep Fig. 14—The dog flea, 
common tick, enlarged. This enlarged 
liver fluke, is not a true tick 
natural size 
This is a good time to dip your sheep for sheep ticks. (Fig. 13.) 
Write for Farmers’ Bulletin No. 798 (22). 
Is your house full of fleas? (Fig. 14.) They are probably presents 
from your dog or cat. Write for Farmers’ Bulletin No. 897 (Z), or 
Department Circular No. 338 (9). 
Southern cattle may show ox warbles in the back at this season of 
the year. See this calendar for February for suggestions as to 
control. 
If you have any areas on your farm, especially low, wet places, 
and also have had lungworm disease, fluke disease, or similar troubles 
in livestock on that area, keep your animals off that land for a year 
or two if possible. If these areas must be used, use them for mature 
animals of a different species. Keep your young livestock away 
from such places. 
The cost of patent worm remedies for a period of years is usually 
much greater than a veterinarian’s fee for sound advice as to treat- 
ment and prevention.
