ADVANTAGES OF CENTRIFUGAL CREAM SEPARATOR 



TO FARMERS. 



1. If farmers have been accustomed to haul their milk to a 

 creamery and bring back skim milk from the factory, the cost of 

 this hauling is seldom less than 10 cents per 100 pounds of milk, 

 or about three cents per pound of butter. 



356. If the milk of a cow contains 200 pounds butter in a 

 year the farm separator, by saving this cost of hauling, earns $6 

 per year or $60 for a herd of ten cows. The cream hauling, how- 

 ever, costs about one cent per pound butter fat and this will re- 

 duce the $60 to $40 gain per year by cream instead of milk hauling. 



2. The feeding value of the skim milk as it comes from the 

 farm separator directly after milking is better than at any other 

 time. Mixed creamery skim milk is not only older, but may be 

 diluted somewhat, and it may also be the means of spreading 

 tuberculosis from one herd to another. 



357. The condition of the creamery skim milk is often the 

 cause of keeping some whole milk on the farm to feed calves. 

 This is rather expensive feed when butter is worth 30 cents per 

 pound, but the calves will not need whole milk when they can get 

 sweet skim milk from the farm separator. The farm skimming 

 therefore helps not only in raising calves economically, but it 

 helps to increase the amount of milk fat sold to the factory. 



3. The farm separator reduces the loss from an occasional 

 can of sour milk which may be sent to the creamery when whole 

 milk is delivered. 



4. The farmer can keep more cows when a farm separator 

 is used, as he has more time at home than when delivering whole 

 milk. 



5. There is more demand for cream than for milk and it can 

 be economically shipped longer distances and thus give farmers 

 the benefit of a wider territory or more extensive market than he 

 is able to get for his milk. 



358. All these advantages which may be obtained from the 

 use of a farm separator are based on its supplying a perfectly
