NINTH ANNUAL YEAR BOOK— PART Vt 223 
ask a question that has been puzzling me for two years. Some of 
my strong pigs from the time they are a day or two old have little 
sore places just below the knees. They have good dry beds and I 
can find no reason for it but the skin seems to wear off and get 
sore. I would like to know the cause of it. ' ' 
Mr. Hockett thought it was caused by the sensitive skin coming 
in contact with polluted bedding, but Mr. Buck stated that he had 
noticed it in thirty-six hours after the pigs were farrowed and in 
good bedding. 
Albert Sundell of Paton, Iowa, had this explanation to offer: 
"I think it is caused a good deal at the time the pig is fighting 
for the right of his table. You always find that when the pig is 
born the first thing he does is to get to work and there is a good 
deal of fighting done during the first twenty-four hours until they 
get their fill and I think they do a good deal of rubbing that skin 
off in getting their rights the first twenty-four hours." 
Mr. Harding said : " I have noticed this a good deal and I think 
you find it on almost all pigs and I don 't think there is any question 
as to what causes it. I may be wrong, but I think it is the doubling 
of that joint back and as they scramble for their place stand on 
that joint and rub it on the bedding. The hair is all turned the 
wrong way and in a short time it becomes irritated and soon forms 
a sore." 
Joe Steward remarked that it might be a breed characteristic as 
he had never seen it on his pigs, and ]\Ir. Buck replied that they 
were cross bred hogs, Poland Chinas and Durocs. In answer to 
Mr. Swallow's question if it was found in small litters, he said he 
had not noticed any difference, that all the pigs had had it for the 
last two years regardless of the size of the litter. 
There being no further remarks on this subject, the subject of 
"Fulfillment of Sale Ring Guarantees" was taken up. The sub- 
ject had been assigned to A. W. Holland of New London, Iowa, but 
Mr. Holland was unable to be present for the reason that his large 
barn and a good deal of his stock was destroyed by lightning lately 
with a considerable loss and for the additional reason that he was 
holding a public sale on this date. 
In regard to this subject H. F. Hoffman of Washta, Iowa, said : 
"I have never had much experience as I never had but one public 
sale. It looks to me as though a public sale guarantee should be 
just the same as a private sale. When a person sells a bred sow 
she should be in pig and should farrow on the date of service he
