FEEDING FOR MILK PRODUCTION 



283 



This is still a little high in energy and low in protein. It can 

 be made nearer the standard by replacing one pound of the 

 corn with bran : 



This ration approaches the standard close enough for practical 

 purposes, although still a little low in protein. 



The ration must be modified to meet the requirements of 

 individual animals to some extent, especially regarding the 

 richness of milk produced. The standard as stated is based 

 upon the requirements for average milk. A cow of the 

 Channel Island breeds will presumably require a somewhat 

 higher allowance for the milk, while one of the Holstein breed 

 may use rather less. An exact agreement with the require- 

 ments is not essential, even when the milk produced is of 

 average composition, since the composition of the feeds varies 

 to some extent, and the individual requirements of the ani- 

 mals are also subject to some variations. 



The Cost of the Ration. In the foregoing no attention 

 has been given to the relative cost of the feeds used in making 

 up the ration. This question is one of great importance, and 

 must always be taken into account. In general the tendency 

 is for the mill products, such as bran, oil meal, cottonseed meal, 

 and the great variety of others on the market to be sold
