20b COMMON DISEASES. 



sheep. Lambs four months old take two to four ounces. Older 

 sheep take three to five ounces. If there is any reason to suspect 

 the presence of worms in the intestines, then thymol should be 

 added to the creosote treatment. The dose of thymol is from 30 

 to 100 grains. Each dose of thymol is to be added to the dose 

 of creosote after the latter has been mixed, measured and should 

 then be given immediately. Only the fresh crystalized thymol 

 should be accepted. The affected animals should be kept from 

 feed for 16 to 20 hours before medicinal treatment is given. 



liluestone (copper sulphate) has been commonly accepted as 

 one of the most satisfactory treatments for this trouble, but it 

 needs to be given in carefully regulated doses. This medicine 

 may be made up as follows: Dissolve one pound (avoirdupois) 

 of fresh powdered Milestone in nine gallons of water. For this 

 treatment the animal must be kept off feed from 20 to 24 hours. 

 The dose for a lamb six months old is 40 c. c. ; sheep 12 months 

 old, 60 c. c. (about two ounces) ; 18 months, 80 c. c. ; two years, 

 90 c. c. 



Drenching sheep. — For giving medicine to sheep a drench- 

 ing tube should be used or a large piston syringe, or a long necked 

 bottle. A very satisfactory drenching tube may be easily made 

 with an ordinary tin funnel which is inserted into one end of the 

 rubber hose about three feet long and about one-half inch in di- 

 ameter. A piece of brass or iron tubing four to six inches long 

 is inserted into the other end of the tube. The metal tube is 

 placed in the animal's month between the back teeth, the funnel 

 end is held at a convenient height and medicine poured slowly into 

 the funnel. In administering medicine for treating the stomach 

 worms, it is better to give the medicine with the sheep standing 

 on its feet, because actual experiment lias demonstrated that while 

 the animal is in this position, more of the medicine goes directly 

 to the fourth stomach where it is needed. 



Prevention. — Sick animals must be removed from the flock 

 and put in a pasture or yard from which there is no drainage to 

 the pasture or yard used by the flock. Water must be taken 

 from good wells that do not receive surface drainage. The tank 

 or trough should be high enough above the ground level so that 

 the water cannot possibly be contaminated from droppings. High 

 and well drained pasture is always safer than low pastures, unless
