82 SHEEP DISEASES. 



For disinfecting a shed or corral, perhaps as 

 good as any disinfectant is lime and sulphur dip. 

 Put a half bushel of unslaked lime in a fifty- 

 gallon barrel, and add enough water to make a 

 smooth paste: Add about twenty gallons of water, 

 stirring constantly, and then add the coal tar dip, 

 about three gallons will be sufficient, and fill the 

 barrel up with water. Allow to stand over night, 

 and by not agitating the solution, one can use a 

 spray pump with little annoyance from clogging. 



The most common western method is to dilute 

 the sediment from the lime and sulphur clips, and 

 throw it around over the corral or pens. 



For detailed formulae of the various dips, see 

 Section on Parasites, page 161. 



Blue vitriol and common lime are the solutions 

 most used in foot rot on the range. 



The Value of Postmortem Examinations. 



Perhaps in no species of animal is an autopsy 

 more valuable than in sheep. To ascertain with 

 reasonable certainty the exact trouble is more than 

 half the battle, and preventive measures can be 

 taken to eradicate the malady, if at all practicable. 



Sheep that have been dead more than twenty- 

 four hours are not good subjects for postmortem 

 examination. The putrefactive organisms and gas 

 have caused such changes that one cannot tell 

 anything about the original ailment. 



Examine the head for grub ; the trachea for lung 

 worms; the fourth stomach for stomach worms; 

 the liver for liver flukes; the skin for scab mites 

 or ticks, and every organ for pathological lesions.
