586 BOARD OF AGRICULTURE. 



anxious, too much has been done; impressions and effects have been 

 produced which checls growth and cause loss. In this respect I say it 

 is bad. 



Here, gentlemen, to me is where the shadows and clouds appear; 

 where there is uncertainty and doubt about the constitutional effects pro- 

 duced with the means furnished. Whether they are a facsimile of those 

 produced by the pig being farrowed in cholera, or the effect of some 

 poison. Until this question is settled we are virtually in the dark at this 

 point. 



The theory of immuning pigs in utero or through lactation seems 

 plausible, but further investigation must be had by which the means 

 may be developed in which there is uniformity of strength and action, 

 so that injury to pigs may be avoided. 



If the serum treatment given to us by our friend Ridgeway will im- 

 mune or destroy that particular element of the system upon which the 

 cholera germ subsists, then nothing but such an article should go into 

 the hands of anyone. We must know what we are doing and how we 

 are doing it. 



It has not been my privilege to test pigs treated by the serum process, 

 therefore can not speak of its efficacy from experience. 



CHEAPEST FOOD FOR HOGb'. 



WALKER S. JOHNSON, NEW AUGUSTA, IND. 



Mr. President and Gentlemen of the Indiana Swine Breeders' Asso- 

 ciation—The subject assigned me, "Cheapest Feed for Hogs," is no doubt 

 the most important subject confronting the breeder at this time. 



We are all aware of the fact that the coming year bids fair to be one 

 of the most successful in the way of a strong demand for breeding stock 

 that we have ever experienced, but in order to make a financial success 

 of it Ave are confronted by the subject assigned me, "Cheapest Feed for 

 Hogs." 



Now for me to say any certain kind or kinds of feed would be cheap- 

 est would be saying too much, for what would be cheapest in one locality 

 might not be in another; therefore I do not think any practical rule can 

 be laid down. But in our own State I would recommend the following, 

 and will say in our own herd, for winter, we use rye pasture with a 

 small amount of corn night and morning, when one can let them on rye, 

 and in summer Ave allow our entire herd the run of a clover pasture as 

 near as possible. For soft feed for our brood sows and breeding males 

 we use one part corn, one part oats and one part bran. The corn and
