FIFTY-SECOND ANNUAL CONVENTION 233 



Exercise t?ie animal by walking. If this does not help, 

 give 2 tablespoonfuls of liquor cresolis compositus (U. S. 

 P.), mixed with 2 quarts of warm water as a drench. After 

 bloating has subsided, give 1 pound of Epsom salt in 3 pints 

 of warm water as a drench. If these remedies are not ef- 

 fective, and in urgent cases where the gas must be allowed 

 to escape without delay, it may be necessary to puncture the 

 paunch. This is best done with a trocar and canula. The 

 trocar is a sharp-pointed instrument which fits smoothly 

 into a hollow tube called the canula, leaving the sharp 

 point exposed. After inserting the trocar and canula, by 

 a quick, firm thrust inward, downward, and forward, the 

 trocar is pulled out and the canula left in the opening. This 

 will allow the gas to escape. The paunch is punctured on 

 the left side with the trocar at the center of a triangle 

 formed by the last rib, the hip bone, and the loin. 



The animal should be fed sparingly on easily digested 

 feed for several days after bloating has stopped, so that all 

 fermenting material may pass out of the stomach. 



Drenching 



Medicine is usually given to cattle by ''drenching," 

 This is commonly done by mixing the medicine with water 

 and giving this by the aid of a long-necked bottle or drench- 

 ing horn through the mouth. The medicine should be given 

 slowly, to prevent choking. A simple drenching tube can 

 be made by using an ordinary tin funnel with a piece of 

 rubber hose. 



Care must be used in drenching to prevent the medi- 

 cine from passing down the animal's windpipe to the lungs, 

 causing pneumonia. In giving a drench the head of the 

 animal should be held in an elevated position. The mouth 

 of the bottle is inserted at the side of the mouth in front of 

 the jaw teeth and on top of the tongue. If the animal 

 coughs, the head should be immediately lowered, to pre- 

 vent the liquid from passing to the lungs. Care should also 

 be taken in holding the animal, to avoid stopping breathing 

 through the nose. Unless one has had considerable ex-
