THE COMPUTATION OF RATIONS 65 



turing enterprises or on chop feeds and other grain 

 materials that may be purchased often as cheaply 

 as hay. The result is, in neither instance are the 

 cows fed as they ought to be. The cow in the 

 country gets too little protein and too much carbo- 

 hydrates and fat; the village cow too much of pro- 

 tein and too little of the carbohydrates and fat ; and 



MIXING THEIR OWN RATION 



These cows have the run of a large area in which several kinds of grasses 

 flourish. Rape is growing in the foreground. 



the best results are not obtained in either case. The 

 country cow loses in weight ; she gets poor ; she is 

 forced to take from her own body much protein 

 stored in flesh to use for milk and tissue repair. 

 The village cow may or may not thin down, but the 

 necessity of using the protein in the food for meet- 

 ing all the functions of the nutrients acts to her dis- 

 advantage and she is never able to be at her best.
