HOW TO PRODUCE FARM ANIMALS 211 



should be made by adding feeds having a narrow nutritive 

 ratio (one having a large proportion of protein), such as 

 clover hay and a small amount of cotton-seed meal.

The corrected ration conforms to the standard more closely 

 than is really necessary in actual feeding practice. 



In standardizing rations it is desirable also to pay some 

 attention to the money value of the feeds used. Often an 

 inexpensive feed which has the same feeding value as an 

 expensive one may be used. Again, preference should be 

 given to feeds grown on the farm, if they can be produced 

 more cheaply than they can be bought. Here it is a question 

 of deciding which is cheaper, home-grown or purchased feeds. 

 For example, one farmer found that he could get the best 

 return from his land and labor by raising potatoes and selling 

 them, and then buying grain for feeding purposes. Making 

 correct decisions in such matters is an important factor in 

 successful farming. There are many things to take into 

 consideration; conditions will vary in different localities and 

 even on different farms in the same community. It happened 

 that the farm just referred to was well adapted for potato 

 growing and situated near a good market. Perhaps other 

 farms in the same region were not so well suited for potato 

 production and could not make such a system profitable. 



Preparing and compounding a ration. After the ration 

 has been standardized it is an easy matter to prepare it.
