F48 ELEMENTARY TREATISE ON STOCK FEEDS AND FEEDING 



A ration to meet the protein standard using red top hay alone 

 would take 48 Ibs. 



There is an excess of 20.7 Ibs. of dry matter and a waste of 

 9.29 Ibs. of carbohydrates in such a ration. A horse could not 

 perform hard work with this ration as it would be impossible for 

 this class of animal to consume such a large quantity of hay. 



2. Using 15 Ibs. of corn (grain), it will take 40 Ibs. of tim- 

 othy hay to approximate the protein requirement. 



This combination is unsatisfactory because it exceeds the dry 

 matter standard by 25 Ibs. and there is a waste of 15.7 Ibs. of 

 carbohydrates. Both of these feeds are proportionately high 

 in carbohydrates. 



3. Substituting alfalfa hay (which is nitrogenous) for the 

 timothy it will take 10 Ibs. of the former to satisfy the protein 

 standard with 15 Ibs. of corn. 



This combination practically balances the ration although the 

 carbohydrates are slightly in excess. In this ration the corn
