SWINE. 259 



pigs will improve it. Any of the supplemental feeds should not 

 be added in large enough quantities to induce scouring. 



PROBLEMS. 



1. If it requires on an average about 5 pounds of corn to produce 

 one pound of weight in growing hogs, would it pay to feed 95c 

 corn, to 5c hogs? What would be the gain or loss per pound? 



2. At the rate of one pound grain for each 5.5 pounds of corn fed 

 in fattening swine, what will be the results on the ledger in 

 feeding 50c corn to 7c hogs? 



3. At the present price of hogs and corn, does it pay to feed corn? 

 (See daily market reports.) 



Feeding Hogs. 



PROBLEMS. 



Tests at the Nebraska State Experiment Station show that hogs 

 fattened on alfalfa hay and corn put on gain at a cost of $3.40 per 100 

 pounds ; while hogs fed on corn alone cost $4.48 per hundred pound gain ; 

 what was gained >by feeding a drove of hogs on a mixture of alfalfa hay 

 ajid corn until they gained 1,640 pounds over another lot that made the 

 same gain fed on corn alone? 



2. The Kansas State Experiment Station reports that a bunch of 

 hogs fed on corn and alfalfa made a gain of 90.9 pounds per hog in 10 

 weeks, while a similar bunch fed on corn alone gained 52.4 pounds per 

 head in the same time. Each lot had all the corn they wanted. Those 

 fed alfalfa had better digestion of corn eaten. The hog receiving alfalfa 

 with corn gained how much more than the one that received corn alone? 

 How much gain would that be on 1,000 pounds weight at present prices? 



3. It is claimed by good authority that sows kept on alfalfa pasture 

 will raise more pigs, and that at 3 months old they will weigh 25 per 

 cent more than pigs raised without alfalfa pasture; what would be the 

 gain in selling 100 pigs grown by this method if pigs raised by other 

 methods are selling at $2.50 per head when 12 weeks old? 



PROBLEM. 



The Alabama Agricultural Experiment Station, after three 

 years' work in swine production, gives following result : 



1. When corn was used alone the average daily gain for each hog 

 was .375 of a pound; when soybeans were pastured, with a fourth of a 

 ration of corn the gain was 1.102 pounds; soybeans with half a ration 

 of corn produced 1.006, and with three-fourths of a ration of corn the 

 production was 1.329 pounds of gain per hog daily; what was the gain 

 per cent by the use of three-fourths ration of corn with soybeans over the 

 feeding of corn alone?
