DISEASES OF SHEEP TREATMENT 209 



four ounces turpentine and eight ounces olive oil ; mix well and inject into the 

 windpipe by means of a hypodermic syringe once a day for three days. Place 

 the animal on his rump and hold between the knees while inserting the hypo- 

 dermic needle into the windpipe two or three inches below the throat, in- 

 jecting the medicine gradually. 



Maggots From Blow Flies. 



Most of the maggots on animals are caused by the flesh-fly. The adult 

 fly deposits her eggs (larvae) on the surface of wounds or in the wool of 

 sheep where manure and other filth has collected. The larvae, as they de- 

 velop, will work their way into the skin, causing sores. When the tails of 

 lambs are docked, the cut surface must be treated with a proper antiseptic and 

 the lamb watched to guard against the fly. 



Treatment. The essential treatment is cleanliness. Heavy wooled sheep 

 should have all wool cut away from parts where it is liable to become soiled 

 and filthy, especially in the spring before the flies come. In case a wound 

 has been attacked, all dead tissue, and as many of the parasites as possible 

 should be removed. Oil or tar, turpentine and lard or kerosene oil are about 

 the best and handiest remedies for preventing the flies from laying the eggs, 

 and also kills the eggs that have been laid. 



Nodular Disease. 



This disease is caused by a parasitic worm which burrows into the walls 

 of the intestines causing nodules or bunches. The trouble is most common 

 and serious in the South and older sheep are more often affected than lambs. 

 The disease is spread by allowing well sheep to graze on pasture which has 

 been used by diseased sheep. Lambs should be prevented from getting the 

 disease. 



Symptoms. General debility; loss of appetite and flesh; the eyes are 

 dull and yellow and the wool is rough. 



Treatment. No. medicinal treatment is satisfactory in ridding sheep of 

 this trouble. Prevent the lambs from grazing after their mothers if there is 

 suspicion of the disease existing. They may be kept on bare lots and fed green 

 crops from racks, carefully removing all food remaining after each feeding. In 

 this way there is little danger of lambs becoming infected even if the ewes 

 are badly attacked by the parasite. The ewes which are infested may thus be 

 kept for breeding purposes without danger of transmitting the disease to the 

 lambs. 



Pneumonia. 



This is the same in sheep as in all other animals affected with it, and 

 develops from exposure to cold which can in most cases be prevented. The 

 simple diseases are not serious in themselves, but it is what they may develop 

 into that should make one especially careful in prevention. 



Symptoms. A chill, followed by fever, great thirst ; panting and heaving 

 at the flanks; quickened respiration and coughing.
