7. Which is probably the best feed for fattening

8. Suppose all kinds of hay sell at the uniform price

9. Which is the cheapest feed? 



10. What is the best kind of straw to feed, and 

 why? How do we find the "nutritive ratio"? What 

 is the nutritive ratio of clover hay? Is it a balanced 

 ration ? 



n. Find the nutritive value of all the feeds given 

 in the tables. 



12. Which are most nearly "perfect" feeds i. e., 

 which have a ratio of about 6 to I ? 



13. Which are the poorest feeds i. e., which have 

 the lowest ratio of protein? 



14. W r hich are the feeds having the largest propor- 

 tion of protein? 



15. Are any of the feeds given in the table so poor 

 that, in themselves; they are practically worthless? 

 If so, name them. 



Illustration. One ton of mixed hay contains 88 Ibs. protein 

 and 880 Ibs. carbohydrates. Its ratio is i to 10. Let us mix it 

 with some other feed to bring the ratio up to about I to 6. We 

 shall try peas. We shall feed I bu. of ground peas with every 

 hundred Ibs. of hay. 



Feed. Protein. Carbohydrates. 



100 Ibs. hay contain 4.4 44 



60 Ibs. peas contain 10. 32 



160 Ibs. mixed contain 14.4 76
