5. The poultry houses, runs, and equipment, should be thoroughly cleaned 

 and disinfected immediately after removal of reactors. Provide an empty pen 

 to each house to facilitate cleaning and disinfection during the winter months. 

 Use disinfectants approved by the United States Department of Agriculture. 



6. Birds removed from the premises to egg-laying contests, exhibitions, 

 etc., should be held in quarantine and determined free of disease before they are 

 readmitted into the flock. 



7. Purchase of stock in the form of adults, chicks, and eggs should be from 

 known puUorum disease-free flocks. Consult your county agent regarding addi- 

 tions or replacements in your flock. 



8. Eggs should not be saved for hatching until after a flock has been tested 

 and all the infected birds removed. Early pullet testing will permit early hatch- 

 ing. 



9. Fresh and infertile eggs from unknown or infected sources should not be 

 fed to chickens or exposed to birds or animals such as crows, sparrows, and skunks 

 that may carry or spread the infection. 



10. Poultrymen should not custom hatch for untested or infected flocks 

 (including fowl other than chickens). 



11. Owners of pullorum disease-free flocks should not have hatching done 

 where infected eggs or stock may be found. 



12. Poultrymen should not buy feed in bags that have been used or exposed 

 to infection. (Such bags if properly disinfected will be safe for further use.) 



13. Poultrymen should regard fowl other than chickens as a possible source 

 of pullorum infection unless tested and found free from pullorum disease. 



14. Poultrymen should not use equipment that has been exposed to or con- 

 taminated with infective material unless it is properly cleaned and sterilized or 

 disinfected. 



TESTING OF FOWL OTHER THAN CHICKENS 



There has been a marked increase in the number of turkeys tested during the 

 past season. This may be explained to a large degree by the rapid expansion of 

 the turkey industry in Massachusetts, including a tremendously increased demand 

 for locally produced hatching eggs and poults. During the season 82 turkey 

 flocks were tested, 11 of which were on farms with tested chickens. 



The following table summarizes the results of testing fowl other than chickens: 



The percentage of reactors among turkeys is rather high. These reactors were 

 confined to 19 flocks, in which the amount of infection ranged from 0.94 to 46.94 

 percent. Eight of the 19 flocks were subjected to either a partial or a complete 

 retest. In a few flocks a negative test was obtained on retest. The following 

 summary shows the range in size for the turkey flocks:
