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 ma\' carry or spread the infection. 



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

 cluding fowl other than chickens). 



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

 where infected eggs or stock may be found. 



12. Poultr\men 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 infecti\-e material unless it is properly cleaned and sterilized or 

 disinfected. 



TESTING OF FOWL OTHER THAN CHICKENS 



During the past year 28,427 fowl other than chickens were tested, including 

 21,231 turkeys, 4,959 pheasants, 2,022 quail, 150 geese, 50 ducks, 3 pigeons, 9 

 chukars, and 3 pea fowl. No pullorum infection was detected. 



The majority of turkey flocks contained less than 500 birds. The following 

 summary gives the range in flock sizes for the turkey flocks tested.

For the last two successive years, no pullorum infection has been detected in 

 fowl other than chickens. Flock owners are advised to continue their vigilance 

 against the introduction of pullorum disease. 



NON-REACTING AND POSITIVE FLOCKS CLASSIFIED BY COUNTIES 



In Table 4 the non-reacting and positive flocks are listed by counties. A total 

 of 452 non-reacting flocks, representing 1,171,363 birds, was detected in 12 coun- 

 ties. Among the 452 non-reacting flocks, 439 were 100 percent tested, represent- 

 ing 1,161,599 birds; whereas 13 flocks were partially tested and contained 9,764 

 birds. In Barnstable, Dukes, Essex, Hampden, and Plymouth Counties, all the 

 non-reacting flocks were 100 percent tested. 



.Six flocks, representing 8,118 birds, were classified as positive at the close of 

 the testing season. Of the six flocks, five were 100 percent tested and one was 

 partial h- tested. The number of positive flocks and birds in such flocks is con- 

 siderably less than in the previous season. It is encouraging to note that the 

 number of infected flocks is declining. When infected flocks are detected, definite 

 plans should be adopted whereby the infection can be eradicated in the shortest
