PRINCIPLES OF FEEDING 211 



Manurial Value of Feeding Stuffs. On account of 

 the value of certain foods as manure, it is also necessary 

 to figure on the manurial value of a food as well as on its 

 feeding value. From the Table on page 261, it may be 

 seen that some substances are of far greater value as 

 manure than others, and this fact should be considered 

 in making a profitable ration, and in determining what 

 foods to sell and what to purchase. 



PROBLEMS AND EXERCISES. 



1. Make a ration for a milch cow of about 1,000 pounds 

 weight, using silage, alfalfa, and wheat bran. 



2. Suppose a farmer has ground oats, corn meal, red 

 clover hay, and stover (cornstalks) on his farm. Could 

 a balanced ration for a dairy cow be made from these 

 alone? Select additional foods from the table to make 

 a balanced ration for a dairy cow (1,000 Ibs.). 



3. Make a ration for a dairy cow (1,000 Ibs.), having 

 the usual ratio of i : 6, of red clover hay, mangels, corn 

 meal, oats, wheat bran, and gluten meal. 



4. A farmer fed his cows, averaging about 1,000 

 pounds each, 10 pounds timothy hay, 13 pounds stover, 

 and 6 pounds straw. His cows averaged but 156 pounds 

 of butter each year. Why does he get such poor results? 

 Suggest changes in the feed that would be likely to in- 

 crease the amount of butter produced. 



5. A fanner feeds a i,ooo-pound steer in the second 

 period of fattening the following ration: 40 pounds of corn 

 silage, 10 pounds of red clover hay, 4 pounds of corn and 

 cob meal, 3 pounds of oats and 6 pounds of gluten meal.
