Save $ 20 Per Cow Per Year 
With a De Laval Milker 
According to an investigation by the University of 
Illinois on 66 dairy farms, it was found that 133.9 hours 
per year were required to milk a cow by hand. A De Laval 
Milker will cut this time in two and save at least 62 hours 
per cow per year over hand milking, and at 15 cents per 
hour a saving of $9.30 per cow per year will be effected. 
Save Time 
This is a very conservative way of figuring the value of 
the time-saving feature of a De Laval Milker. In actual 
use it may save a man; or if a man is still retained it may 
mean that more cows can be kept or that he can devote 
all his time to other work, the owner looking after the 
milking himself. Or it may mean that a boy or some 
other person not capable of doing much milking by hand, 
with the aid of a De Laval can take the place of a grown 
man. 
Get More Milk 
But saving time is only part of the advantage of a De 
Laval Milker. Suppose a De Laval, because of its uni¬ 
form, vigorous and stimulating action, will increase 
production 10%. Of course the De Laval Company can’t 
guarantee such an increase, as there are so many uncon¬ 
trollable factors, such as health, feed, climate, care, etc. 
But practically all De Laval Milker users, and especially 
those who weigh their milk and know, do say they get 
more milk, taking the h.erd as a whole over a period of a 
year—some as high as 20%; and 10%, based on the results 
obtained by many users, seems conservative. Ten per 
cent of 3000 pounds of milk per year—about the average 
production per cow per year—is 300 pounds, which at 
$2.20 per cwt., the average price of fluid milk in the 
United States delivered at country stations during 1922, 
would be $11.00 per cow per year. Then add this to the 
value of the time saved, which is $9.30, and you will have a 
total gain of $20.30 per cow per year, due to the use of a 
De Laval Milker. 
Multiply this by 10, 20, 30, or the number of cows you 
are milking by hand, and you get a very conservative idea 
of what a De Laval Milker really will make you in profit. 
Makes Dairying More Pleasant 
and Profitable 
In addition, when it is considered that cleaner milk 
can be produced, that the drudgery and dislike of hand 
milking are eliminated, and that dairying is made more 
pleasant for owner, son or hired man, you have the 
answer why so many people are installing De Laval 
Milkers—and especially when it is borne in mind that a 
De Laval Milker can be bought on such liberal terms 
and such long time that it will actually pay for itself as 
it is being used.
