PREVENTION, SYMPTOMS AND TREATMENT jo, 



seat of disease. The parasites may be discovered by examination 

 of the scrapings of these parts with a low power lens. 



Preventive treatment includes the destruction of the feces and 

 litter by fire, the use of pure drinking water, the isolation of the 

 sick, and the treatment of infected pastures with lime. Turpentine 

 and thymol have proven the best anthelmintics. Oil of turpentine 

 may be given to cattle in 4-ounce doses, in a pint of linseed oil, and 

 thymol to sheep (lambs, 3ss; sheep 5i-iss) in 1 per cent, watery 

 solution of cold tar creosote. 



A chronic, epizootic condition (strongylosis) occurs in sheep 

 due to several species of strongylus in the abomasum, often assoc- 

 iated with tape and hook-worms in the bowels. This — like hook- 

 worm disease in dogs — leads to loss of flesh, strength, appetite and 

 spirits. The wool drops out and the animals die in the course of 

 months of anemia and exhaustion, with fetid diarrhea toward the 

 last. Ova are found in the feces and strongylides on scraping the 

 mucosa of the abomasum. Treatment is comprised in isolation of 

 the sick, treating pastures with copperas, 80 lbs. to acre in 10 per 

 cent solution ; good feeding, plenty of salt and the administration on 

 bran once daily of 100 gr. of areca nut with 2 gr. of arsenic for 

 each sheep for a period of five or six days. 



Gapes. — This disease is caused by the Strongylus or Syngamus 

 trachealis, which attacks hens, turkeys and other birds. The em- 

 bryos live in the soil and may inhabit earth-worms and when taken 

 up by birds lodge in the upper part of the trachea, where they de- 

 velop into small, round worms. 



The disease is shown by dulness, gaping, coughing, and ejec- 

 tion of the parasites. Suffocation is often produced, when the birds 

 appear to gasp for air. Ova of the parasites appear in the feces. 

 Treatment includes isolation of the sick and the burning of bodies 

 of the dead. 



By means of a feather dipped in turpentine some of the para- 

 sites may be removed from the trachea and others killed, or trach-
