46 TWENTY-THIRD ANNUAL YEAR BOOK— PART II. 



health certificate, and then if your exhibitor should exhibit animals there 

 that were not on this test then he is liable. 



The wording of the ruling is that all animals exhibited at any of 

 the fairs shall have a health certificate. The ruling on the hogs is 

 that each one must be immuned. The ruling on your tuberculosis is 

 very plain and was amended last year. The first rule put into effect you 

 know about the accredited herd system of the State of Iowa, but up to 

 last year we didn't have very many fully accredited herds. We had 

 up to the first of July 779 herds and at the present time over 1100 herds 

 fully, accredited. That rule was amended last year to take care of herds 

 that had passed a clean test, so that any herd that has passed a clean 

 test has a right now under this ruling to exhibit at any fair for one 

 year. That ruling is applied to accredited herds. In testing out a herd 

 of cattle if you gentlemen have one that has passed a clean test you 

 are not due for another test until one year from date. Therefore it 

 would be a hardship to make this man who has had a clean test record, 

 to require a ninety day retest before exhibiting at the fair, so we 

 amended the rule and it now requires all cattle presented for exhibition 

 or other purposes at the Iowa State fair or any fair or exhibition in the 

 state of Iowa shall be from a tuberculosis free accredited herd or from 

 a herd which has passed one clean test within one year under the plan 

 for the accrediting of herds; and show cattle other than those above 

 specified shall have passed a satisfactory tuberculin test and found to 

 be free from tuberculosis not more than ninety days prior to the date 

 of the exhibition at such fair. That is the rule as it stands now on the 

 cattle. 



The rule on hogs is all swine exhibited at state, county or other fairs 

 or exhibitions in the State of Iowa must be accompanied by a certificate 

 showing that they have been immunized with anti-cholera serum and 

 virus not less than thirty days; when serum alone is used mot more 

 than fifteen days prior to the date of said fair or exhibition. These 

 rules and regulations have all been submitted to the Executive Council 

 and approved by them and they have become law. 



A Member : What are the rules as regards disinfecting buildings 

 and grounds ? 



Dr. Malcolm : We have a rule there that includes your county as 

 well as the state, that they should be thoroughly disinfected. 



A Member: I would like to ask the doctor in case in a county 

 where there is no cholera would you consider it a hardship to compel 

 them to use the double treatment on a herd of hogs if they are going 

 to exhibit 



Dr. Malcolm : You have reference to hogs on exhibit. You will 

 notice in that rule we do not require you to immunize hogs and use 

 virus. We allow you to use serum for your own protection, not 

 for the protection of anybody else, because we are fearful that when 

 you get into a show, some individual or hog may have carried the
