The Croup in Calves, 339 



S3n^ptoms. — Tliere are a hoarse cough, discharge of spittle 

 from the mouth, and running from the nose. The animal 

 does not thrive, swalloAvs with an effort, and in drawing in 

 its breath a whistling or crowing noise is heard. 



As the disease progresses the breathing becomes more 

 labored, the cough is more violent and in paroxysms, and 

 shreds of false membrane are coughed up. 



Treatment. — A moderate purge at the outset will be found 

 of use, and small doses of saltpetre in the drinking water, to 

 allay the feverish symptoms. To relieve the throat of the 

 false membrane, it will be of benefit for the calf to in- 

 hale the vapor from slacking lime (taking care that it is not 

 too concentrated).

Cause. — These worms generally attack calves under one 

 year old, and especially such as are pastured in low-lying 

 lands, near rivers, and subject to flood. They are mostly 

 seen in the months of August and September. Sometimes 

 they are very numerous, and are found after death congre- 

 gated together in a ball in the windpipe, thus choking the 

 animal to death. " 



Symptoms. — The complaint is marked by a hoarse, bron- 

 chial cough, called the " husk ^' or " hoose," loss of flesh, dif- 

 ficulty of breathing, and suffocation to a- greater or less de-

 be detected. It is white in color, the body an inch* or two 

 long, and slender as a thread. Whenever in the autumn
