DISEASES OF CATTLE 155 



Tkeatment: Preventive measures are important, as 

 damp, marshy soil favors the development of the em- 

 bryos. High sloping ground is preferable for pasture. 

 If low ground is used it should be properly drained ; 

 burning over the pasture will destroy most of the young 

 worms on the grass and on the ground. Cattle should 

 be supplied with water from flowing streams or wells 

 and not stagnant ponds. 



Medical Treatment: Withhold all food for twenty- 

 four hours; then administer Oil of Turpentine, placing 

 it in an ounce capsule and give with capsule gun. Fol- 

 low in six hours with a physic consisting of Aloin, two 

 drams; Ginger, two drams. Place in capsule and give 

 with capsule gun. When this worm develops in calves, 

 give as follows : One dram of Turpentine to a calf three 

 months old, four drams to a calf six months old, six 

 drams to a yearling. To cattle two years and over, give 

 equivalent dose, or an ounce. The physic should l3e 

 reduced in the same proportions as that of Turpentine. 



VERMINOUS BRONCHITIS 



(Lung Worms) 



Cause: Due to worm or parasite called Strongylus 

 Micrurus, a small thread-like worm two to four inches 

 in length, found in the bronchial tubes, a portion of the 

 lungs. The life history of this parasite is not known, 

 but infection is apparently derived through the medium 

 of pastures where infested cattle have grazed. Young 

 cattle are more seriously affected than old animals, es- 

 pecially common in low marshy pastures. 



Symptoms : This form of bronchitis usually affects the 

 entire herd; the animals become poor, unthrifty, hack- 

 ing, coughing, especially at night, and sometimes animals 

 actually cough up worms. 



Treatment: Various treatments have been recom- 

 mended for Verminous Bronchitis, or Lung Worm, as
