started pigs with new milk, shorts and a little corn. He thought 

 that the milk of one cow i'ed to a litter of tive pigs would make the 

 pigs have a value in the fall sufficient to pay for a good cow. 11. R. 

 Blake said he fed new milk, oil meal, and tankage and gave the pigs 

 the run of a clover pasture. Secretary Hancher fed a variety, in- 

 cluding oil meal, tankage, bran and shorts three times a day with 

 shredded corn two times a day and gave them access to a blue grass 

 pasture. He increases the proportion of corn as the pigs grow older. 

 Nothing, he said, finishes a pig as well as corn. He fed bran to add 

 bulk. He said that little pigs fed five times a day did well, but that 

 for older ones feeding three times a day answered the purpose. He 

 feeds tankage and oil meal on pasture. He slops before giving the 

 grain feed. He uses 100 pounds of bran and 400 pounds of shorts 

 and includes about a quart of salt to each barrel of slop. He be- 

 lieves in feeding often and only so much as the pigs will clean up 

 each feeding time. 



METHODS OF CONTROLLING AND ERADICATING HOG CHOLERA 



IN IOWA. 



Dr. Stange took up as the subject of his talk "Methods of Controlling 

 and Eradicating Hog Cholera in Iowa." He stated that the eradication 

 of hog cholera is most difficult in practice. Cholera had first presented 

 itself in Ohio in 1833, and it had gradually spread until it was now 

 common in practically every country in which hogs are raised. It 

 seemed that hog cholera came in waves, that it would become prevalent 

 for three or four years with increasing fatality, and that it would then 

 begin to disappear. This year, he said, it would probably reach the 

 high point in Iowa and begin to grow less. Pew disease germs have 

 so great vitality as those of cholera. Carbolic acid does not injure them 

 and the germs have been known to live for two years. Hogs that once 

 pass through cholera do not have it the second time. Sucking pigs do 

 not become readily infected. Some preventives may have merit. Most 

 of them claim too much. There are two forms of hog cholera lesion, 

 one of which appears in the lungs and the other in the intestines. When 

 they have the form found in the lungs the affection is commonly spoken 

 of as swine plague. This form is most serious. Buyers should quaran- 

 tine animals brought to the farm for three weeks before permitting 

 them to mingle with the farm stock. After an animal has been exposed 

 to cholera the contamination will show itself in less than three weeks. 

 Every precaution should be taken. Hogs should not have access to 

 streams rising outside the farm. Streams are the most common means 

 of spreading cholera. Stray dogs assist. Crows- and pigeons do their 

 share. Hog buyers and neighbors should be excluded from the herd 

 in times when cholera is threatened. Dr. Stange thinks the simultaneous 

 method of inoculation is the only one of real merit. He thinks that the 

 introduction of cholera at the time of inoculation should be through
