A CALENDAR OF LIVESTOCK PARASITES 13° 
YEAR-ROUND PARASITE PRECAUTIONS 
Permanent pastures perpetuate parasites! Change your stock 
from one pasture to another, and change the kind of stock on the 
same pasture as far as possible. Follow sheep and cattle with horses 
or swine. 
Don’t overstock. Overstocking concentrates pasture infection, 
resulting in more worm eggs and young worms to an area, and 
increases the chances of stock picking up the infection. 
Use the swine-sanitation system in raising pigs. It will put 
money in your pocket and build up your bank account. 
Put your young livestock on clean and safe areas away from older 
animals other than the mothers and away from areas which have been 
occupied by the older animals. Older animals carry parasites and 
diseases, and the areas occupied by them are infected. Young 
animals are more susceptible to trouble from these causes. Give 
the young animals special care and attention, as you would a baby. 
Most of the losses among livestock occur in young animals. 
If animals are unthrifty, the trouble is probably poor breeding, 
poor feeding, or parasites. If it isn’t the first two, suspect parasites 
of being the cause. 
Chickens and turkeys are a bad mixture. Turkeys convey gape- 
worms to chickens, and chickens convey blackhead to turkeys. 
Raise one or the other, but not both unless you can keep them well 
separated. 
Preventing trouble by sanitation and good farm practice is the 
business of the farmer. When disease is actually present it is advis- 
able to call in a competent veterinarian and to do it early, before 
losses occur. It is better to sacrifice a sick lamb or chicken to find 
out the cause of trouble than to lose a large part of the flock. 
Quarantine all new stock brought on to the place to be sure you are 
not introducing parasites and disease. 
Burn or bury carcasses to prevent the breeding of screw worms 
and the transmission of dangerous parasites directly or as a result 
of dogs’ eating the carcasses and spreading infection. 
Drain or fill in the wet areas on your farm. Such places breed 
parasites. 
Keep your dogs free from parasites, as some of the parasites that 
infest them are transmitted to man and livestock. 
Spread manure frequently and plow it in. Don’t keep it around 
- to breed flies. In the spring, plow your old straw stacks and loose 
straw under, or burn them; they breed stable flies. 
In the South parasites are likely to be prevalent throughout the 
year or to occur earlier in the year than in the North. 
Send any unusual parasites to the Department of Agriculture for 
identification and write for advice. 
Clean up your yards, corrals, stables, and all small inclosures every 
spring and fall, and keep the entire premises in reasonably clean and 
sanitary condition at all times. Parasitic diseases and other diseases 
flourish in dirty places. Cleanliness is profitable to the farmer and 
stockman. ;
