A CALENDAR OF LIVESTOCK PARASITES 3 
MARCH 
Plan to raise young pigs free from roundworms 
by following the system of swine sanitation. 
Clean up places that later may breed flies. 
In the South help eradicate cattle ticks by dip- 
ping regularly. 
In your spring farrowing operations, follow the system of swine 
sanitation developed by the Bureau of Animal Industry. This will 
enable you to avoid large losses from such parasites as roundworms 
(ascarids) (fig. 3) and from kindred conditions associated with dirty 
hog lots, such as bullnose and simi- 
lar troubles. It will not prevent 
losses from bad breeding, bad feed- 
ing, bad management, bad judg- 
ment, chilling, 
accidents, and 
similar causes; 
you will have to 
prevent these by 
appropriate meas- 
ures. However, 
the system of san- 
itation has paid 
big returns to the 
men who have 
used it. It will 
pay you. Write to 
the Department 
— of Agriculture for

your scattered 
straw stacks to breed stable flies. Plow straw under or burn it. 
Write for Farmers’ Bulletin No. 1097 (3). Scatter manure on fields 
to prevent fly breeding. Write for Farmers’ Bulletin No. 1408 (10). 
Dip that tick. The cattle or fever tick (fig. 4) transmits Texas 
fever, reduces beef and milk production, makes costly and annoying 
quarantine necessary, and ticky cattle sell for one-half cent to 2 
cents per pound less than tickless cattle. Southern cattle owners in 
areas quarantined for the fever tick should begin now and by dipping 
every 14 days until November eradicate this pest. In regions where 
the blue bug or fowl tick occurs, spray henhouses, and especially 
the nests, with anthracene oil. (See Farmers’ Bulletin No. 1070 (2).)
