172 SHEEP DISEASES. 



ing on the severity of the invasion, death may 

 take place in from two weeks to two months. 



A postmortem examination reveals the pres- 

 ence of clumps of reddish-brown worms, about 

 half an inch long, and size of a hair, living in a 

 brown liquid, in the lower part of the fourth 

 stomach or abomasum. 



Treatment: In a small band of sheep, treat- 

 ment can be instituted with a fair degree of suc- 

 cess if started in time. Segregate all suspected 

 cases and keep them in a corral. Drive the ap- 

 parently healthy ones to another pasture, pref- 

 erably a high and dry one. Keep all food away 

 from the ones to be treated for a whole day, al- 

 lowing plenty of water. That evening give to an 

 ordinary lamb one-half ounce each of gasolin 

 and raw linseed oil, to which may be added four 

 ounces of fresh cow's milk. Repeat this dosage 

 for three evenings, allowing food several hours 

 after giving each dose of medicine. Very weak 

 lambs may be fed more often, and a little stim- 

 ulant given. Ten days later, give another course 

 of this same treatment. 



Prevention of stomach worms is more to be de- 

 sired than any treatment however successful. 

 It is best accomplished by frequent change of 

 pasture. In case this is impossible, it is a good 

 plan to go out of the sheep business, for stomach 

 worms and profit do not go hand in hand. Fight- 

 ing this disease is not only an expensive battle, 

 but an uphill task as well.
