STOCK FEEDING. 13 



be expected only from about 50 per cent, of the total nutrients 

 required by the cow. This means that a cow on a full ration 

 will yield practically twice as much milk as she would on three- 

 fourths of a ration. Yet there are thousands of dairymen who 

 fail to supply the last quarter of a ration and thus bring ruin 

 upon themselves and their business. 



TABLES GIVING COMPOSITION OF FEEDS. 



At the beginning, it was stated that a knowledge of the com- 

 position of feeds was necessary for two reasons : first, to enable 

 the feeder to determine the relative value of the feeds at his 

 disposal ; and second, to assist in determining what quantity of 

 feed is necessary to supply the required nutrients. To afford 

 the feeder as wide a choice as possible, a long table of feeds is 

 herewith presented, showing not only the digestible, organic 

 nutrients, but also the fertilizing constituents. This long table 

 is taken from Henry's "Feeds and Feeding," by permission of
