218 DISEASES DUE TO INTERNAL PARASITES. 



yield to treatment sets in, the effect of which is to so increase the 

 debility and wasting that the animal falls down unable to rise, 

 quickly succumbing from exhaustion.

This is also both curative and preventive. Where taenia 

 expansa is suspected in a flock all the animals should be dosed, 

 as the well ones if allowed to graze in the same pasture as those 

 already affected are sure to pick up the eggs of the parasite, and 

 in turn become mediums for its distribution. Before adminis- 

 tering vermifuges to the sheep they should be prepared for the 

 same by being kept without food and water for at least twelve 

 hours. They should be all dosed at one time and kept confined 

 for at least twenty-four hours after receiving the medicine, so 

 that the segments and eggs, which will be voided, are not dis- 

 tributed over the pastures. When the owner or foreman is satis- 

 fied that the medicine has had the desired result, the sheep should 

 be allowed access to the pasture, and the yard in which they were 

 confined should be thoroughly covered with quick lime to de- 

 stroy all evidences of the disease. One of the best and simplest 

 taeniacides to use is kamala. This is obtained in the form of a 

 coarse red powder, its effects on the sheep for the expulsion of 

 tapeworm being very satisfactory. Take 



Kamala 3 drachms 



Mix thoroughly in three ounces of linseed gruel ; this is the 

 dose for adult sheep, lambs take from one to two drachms, ac- 

 cording to their age. This should be administered very slowly 

 to the animal to insure its passing into the fourth stomach and 

 so on into the intestines, as, if it should be hastily given, it is 

 liable to enter the rumen, where its effects would in all probabil- 

 ity be nil. Should the kamala not prove efficacious the follow- 

 ing can be tried.
