DAIRY FARMING 



assumed, the cow becomes unconscious and remains so until 

 death, which occurs within about 24 hours if treatment is 

 not given. Fortunately the air treatment, which was dis- 

 covered a few years ago by Anderson in Denmark, makes it 

 possible to relieve nearly every case. 

 When this is properly applied, the cow 

 will recover completely within a few 

 hours and no bad effects follow. With- 

 out treatment, recovery seldom occurs. 

 An approved apparatus is shown in 

 Fig. 45. The essential parts are a 

 milk tube, a receptacle of some kind 

 in which clean cotton is placed to catch 

 the dust in the air pumped through it, 

 and a rubber bulb or pump of some 

 kind. In case a regular apparatus is 

 not at hand, one that will serve the 

 purpose can be improvised from mate- 

 rials generally found in a drug store. 



In using the apparatus the operator 

 should first thoroughly clean his hands, 

 likewise the cow's udder and teats, 

 with warm water and soap, followed 

 by a 2 per cent solution of carbolic 

 acid or creolin. That portion of the apparatus which 

 holds the cotton, the rubber tube, and milk tube, must be 

 clean, and preferably boiled for 15 minutes before using, 

 then disinfected by the use of the carbolic acid or creolin. 

 The receptacle for holding the cotton is filled with ordinary 

 cotton, or, better still, absorbent cotton, which may be 

 purchased at most drug stores. The milk tube is inserted 

 into one of the teat openings without drawing any milk, and

 outfit. The milk tube is 

 inserted in the milk duct 

 of the teat and air is 

 pumped through steri- 

 lized cotton placed in the 

 small cylinder.
