78 STOCK AND FEED PROBLEMS 



EXERCISE 



1. What is the nutritive ratio of a ration consisting of 

 1 bu. of oats mixed with 1 bu. of corn ? 



2. What is the nutritive ratio of a ration consisting of 

 5 Ib. of corn, 1 Ib. of cottonseed meal, 8 Ib. of cowpea hay, 

 and 30 Ib. of corn ensilage ? 



3. What is the nutritive ratio of 100 Ib. of wheat bran 

 and 1 bu. of corn ? Is this a suitable cow feed if a nutritive 

 ratio of about 1 : 6 is a balanced ration for a dairy cow ? 



4. What is the cost of feeding a work team 56 ears of 

 corn per day during January, at 50$ per bushel (100 ears to 

 the bushel), and 32 Ib. of timothy hay daily at $12 per ton? 



5. It has been demonstrated at a state experiment station 

 that a farm horse at steady work should be fed each day 

 1 Ib. of grain and 1.2 Ib. of hay for each 100 Ib. of its weight. 

 If 100 ears of corn make 1 bu. (56 Ib.), how many ears 

 should be fed per day to a work horse weighing 1200 Ib. ? 

 to a horse weighing 1500 Ib. ? 



6. A state experiment station that made recent tests in 

 feeding farm horses reports that the present method of 

 feeding horses as practiced by most farmers is uneconomi- 

 cal, as to the amount and kind of grain fed. The average 

 loss per day on each horse is placed at 20. What is the 

 annual loss in feeding a team ? 



7. The department of agriculture of a Western state esti- 

 mates that the average farm horse of that state works about 

 1000 hr. per year, and is fed about 5215 Ib. of grain and 

 7073 Ib. of hay annually. If the grain is worth f per 

 pound, and the hay %$ per pound, find the cost of the horse 

 labor per hour. 



8. If a mule doing the same work as a horse can be fed 

 for 30 less per day than the horse, what is the annual sav- 

 ing to a farmer in using a mule team instead of a horse team?
