302 SHEEP FARMING IN AMERICA. 



of union of the rubber and metal tubes, he can 

 easily control the flow of the fluid by pinching 

 the rubber hose. Care must be taken not to 

 hold the patient's nostrils closed, otherwise the 

 dose will enter the lungs. 



It is usually advisable to fast animals 12 to 

 16 hours; before dosing. 



POSITION OF ANIMAL DUKING DEENCHING. 



Different persons prefer to hold the animals 

 in different positions during drenching. Thus 

 (1) the animal may be left standing on all foui' 

 feet; or (2) it may be placed on its haunches,- 

 one man holding its back tip against his own 

 body; or (3) it may be placed directly on its 

 back on a sloping piece of ground, its head be- 

 ing in a direct line with its back, and higher 

 than its rump; or (4) it inay be placed upon its 

 side, the head being brought around so that the 

 horns are squarely on the ground; the operator 

 may then place one foot on one of the horns 

 • (especially in the case of semi-wild cattle) and 

 thus aid in holding the animal still. 



So far as administering the doses is con- 

 cerned, the position on the back (3) is by far 

 the easiest in the case of sheep, aad the side 

 position with head down (4) is the easiest in 

 dosing cattle; furthermore, in these positions 

 there is much less danger of an accident by 

 getting the dose in the lungs. If animals are 

 dosed standing or on their haunches, the nose 

 should never be allowed to go above the eyes; 

 otherwise the drench may pass down the wind- 

 pipe into the lungs.
