62 SWINE PRACTICE 



Ether may be used for a general anesthetic in swine but must be 

 carefully administered. 



Chloral hydrate is a narcotic that is probably more applicable to 

 swine, as it is much less dangerous than chloroform or ether. Chloral 

 is easily administered in solution by rectal injection. The usual 

 dose is one dram per 100 pound weight of the hog. It requires 

 about twenty minutes to produce stupor, although in some cases 

 profound narcosis will result within twenty minutes after the chloral 

 has been administered. 



Some practitioners use a combination of chloral and chloroform, 

 administering the chloroform about fifteen to twenty minutes after 

 the chloral is injected. This combination should be employed in 

 cases in which it is necessary to maintain anesthesia for a long 

 period of time. 



Other practitioners have reported good results from the admin- 

 istration of H. M. C. tablets dissolved and injected into the ear vein. 

 The dosage for a mature animal is one tablet composed of hyoscin 

 1-100 grain, morphin % grain and cactoid 1-64 grain. About fifteen 

 minutes are required after the injection before the influence of the 

 drug is noted and operations such as cesarean section can be done 

 within twenty to twenty-five minutes.
