fork or in a hamper should be determined once for all. 

 With this knowledge the weight of fodder may be 

 Closely estimated without actual weighing at each 

 feeding. 



Questions 



1. What is meant by a ration? 2. What Is meant by nu- 

 tritive ratio? 3. What are feeding standards? 4. How are 

 feeding standards determined? 



PROBLEMS 



1. We wish to mix a ration for a fattening ox weighing 

 1,000 pounds, and for food have decided to use 30 pounds 

 corn ensilage, 5 pounds cottonseed-meal and 5 pounds mixed 

 hay. How much wheat straw must be added to complete the 

 ration? 



2. Suppose we have a herd of wool-growing sheep and 

 wish to feed them during the winter. Our sheep weigh 

 about 130 pounds each, so that eight sheep weigh about 

 1,000 pounds. The food we have to give them consists of 

 shelled corn and mixed hay. Calculate the amount of each 

 food necessary to supply the proper ration. 



3. Calculate the nutritive ratio in a ration supplying 2.3 

 pounds of protein, .88 pound fat and 14 pounds carbohy- 

 drates.
