222 DAIRY CATTLE AND MILK PRODUCTION 



still in the experimental stage, the milking machine is at present 

 sufficiently well developed to be a commercial success in the 

 hands of some operators. It is thoroughly demonstrated that 

 it will milk cows, and that by its use a skillful operator can do 

 as good work as the average milker. It seems, however, that 

 it is not yet equal to a good milker in the amount of milk that 

 will be secured. The cow is not inj ured in the least, and in fact 

 prefers machine to hand milking. Most users have found it 

 more difficult to hold up the yield of milk with the machine 

 through the entire lactation period than when hand milking 

 is practiced. If the machine is properly cleaned and used, the 

 sanitary condition of the milk is much improved over any 

 ordinary conditions ; but with careless handling the quality of 

 the milk may be even worse than hand milking. So far it is 

 only practical for herds of 30 cows or more. 



The Hegelund Manipulation. This system of manipula- 

 tion was originated by Dr. J. Hegelund, a teacher in a Danish 

 agricultural school in 1900. It was brought to the attention 

 of dairymen in this country by Professor Woll of Wisconsin. 

 It is really a manipulation of the udder made by the milker as 

 soon as the regular flow of milk has ceased, in order to secure 

 all the milk secreted by the cow. This manipulation serves 

 the same purpose as ordinary stripping, but is claimed to be 

 more efficient. The system has been tested by Woll l and by 

 Wing and Foord. 2 The manipulations, three in number, are 

 described as follows by Woll.
