A glance at the above Feeding Standards indicates the necessity 

 of the feeder having at hand tables showing the composition of the 

 feeding stuffs he is using. In the tables on page 116 and following, 

 compiled from various sources, (Henry's Feeds and Feeding in most 

 cases) will be found t'he quantity of dry matter, digestible protein 

 and digestible carbohydrates, plus fat, (the latter multiplied by the 

 co-efficient 2-], that is 2-25) in 100 pounds of an average sample of 

 each of the feeding stuffs mentioned. Not infrequently, feeds being 

 fed differ materially in composition from the average as given in 

 the tables just mentioned. This might be due to various causes, 

 as weathering in the case of hay, or drought at filling time in the 

 case of grain. 



Among the feeds in the tables as mentioned above, will be found 

 a number that, so far as composition is concerned, come very nearly 

 fulfilling the requirements of the Feeding Standards. We know 

 that it is impossible, however, without serious injury to the health 

 of the cows and to the yield of milk, to feed them exclusively on 

 any one feed, as roots or grain, or even on good corn ensilage alone, 

 and that to ensure good results, these feeds must be mixed in certain 

 more or less definite proportions, sudh as theory and practical agri- 

 ctuilture have together worked out. 



A study of the different kinds of foods available is, therefore, 

 necessary so that the proper quantities of the substances in the 

 foods, viz, proteins, carbohydrates and fats, may be given to the 

 animals and the best results thus attained. 



Moreover, it is necessary, both for the sake of economy and for 

 the health of the animal, to weigh or measure the amount of feed 

 given to each. In order that a cow may digest her food to the best 

 advantage, she must receive a considerable volume of bulky food,
