ERADICATION OF PULLORUM DISEASE 1930-31 17 



"Government Tested," should be avoided when advertising a pullorum dis- 

 ease-free flock. These terms have been used from the time testing for pullor- 

 um disease was first started. They are general terms and are misleading. 

 Owners of pullorum disease-free flocks should so word their advertisements 

 that there may be no doubt in the buyer's mind as to what the status is. 



There are tests for other poultry diseases beside the agglutination test for 

 pullorum disease infection, and flock owners should say for what the flock 

 was tested; that is, they should not stop with the phrase "State Tested," but 

 should specify the test as "State Tested for Pullorum Disease." Flocks 

 which had every bird on the premises tested should so state, i. e. "100 Per 

 cent State Tested for Pullorum Disease." Owners of flocks which are 100 

 per cent tested and are free from pullorum disease should make these facts 

 known. These flocks are the safest from which to purchase stock and are of 

 great importance in the program of eradication. 



Following are a few examples of advertisements used by poultry flock own- 

 ers where every bird was tested for pullorum disease and where no infection 

 was found. 



A. "State Tested." 



For 5 consecutive years 100 per cent tested and 100 per cent free 

 from Pullorum Disease (B.W. D.)^ — never had a reactor. 



B. 100 Per cent— State Tested— Free from B. W. D. 



C. Every Bird Tested— 100 Per cent Clean. 



D. 100 Per cent State Tested— 100 Per cent Clean. 



B, C, and D would be strengthened by wording as follows: — 



B. 100 Per cent— State Tested for Pullorum Disease (B. W. D.)— Free. 



C. Every Bird Tested for Pullorum Disease — 100 Per cent Free. 



D. 100 Per cent State Tested for Pullorum Disease — 100 Per cent Free. 

 The following advertisements also describe flocks of the same status as the 



preceding. While they are clear in conveying the fact that no pullorum in- 

 fection was found, the buyer does not know what portion of the flock was 

 tested. 



A. State Tested, 100 Per cent Pullorum Disease Free. 



B. 100 Per cent Free from Pullorum Disease by State Test. 



C. From Blood Tested Stock, 100 Per cent Pullorum Disease Free (B. 



W. D.). 

 The following terms should be avoided as they may be used where pullor- 

 um infection is present or by hatcheries buying hatching eggs from many 

 sources. 



A. From Our Own Disease-Free Stock. 



B. Trapnested, Blood Tested. 



C. Tested Chicks of Proved Quality. 



D. State Tested Stock. 



E. Officially Blood Tested. 



The following points should be considered in describing the status of a 

 poultry flock as regards pullorum disease: — 



1. Tested for what? 



2. What portion of flock is tested? 



3. Year flock was tested. 



4. Under whose supervision was test made? 



5. Results of test.
