14 and 15 show difference between use of alfalfa and native hay. 

 19 and 21 show results with rape pasture. 



PROBLEMS. 



1. In ration 1, how many pounds of each kind of feed will be re- 

 quired to produce one pound gain in lambs? 



2. In ration 7, how many pounds of each kind of feed will produce 

 one pound in grain? 



3. In ration 23 how many pounds of each kind of feed will be re- 

 quired to produce one pound of weight? 



Feeding Problems. 



1. If 4.98 pounds of corn plus 3.83 pounds of clover hay will produce 

 one pound of gain in lambs; what is the gain or loss in feeding corn at 

 70c a hundred and clover at $10 a ton at the present price of lambs? 



2. What will be the cost of a ration that will produce one pound 

 of gain in lambs, if it consists of 4.12 pounds of clover hay plus 4.47 

 pounds of corn and oil meal mixed (5:1), if hay is $12 per ton and corn 

 is 50c a bushel and oil meal is $32 per ton, when lambs are selling for 8c 

 a pound? 



3. If a feed consists of: 



Corn and Oil meal 5:1 5.07 pounds. 



Corn stover , 5.27 pounds. 



Compare cost of ration at present prices with the present selling 

 price of lambs per pound. 



4. If ration number 6 in the table will produce an average daily gain 

 of .36 of a pound, what will be the cost of a ration that will produce a 

 pound gain if it is composed of the same foods mixed in the same ratio, 

 when lambs are selling at the present price?
