DISTRIBUTION OF TESTS AND REACTORS 



Table 1 gives the number of tests and reactors by counties. P'lock owners in 



12 counties were given testing service. A total of 1,225,594 samples was tested 

 which revealed 0.12 percent reactors. In only one county, Dukes, were no 

 reactors found among the birds tested. However, seven counties (Barnstable, 

 Bristol, Essex, Middlesex, Norfolk, Plymouth, and Worcester) had either 0.1 

 percent or less reactors among the samples tested. Bristol, Middlesex, Norfolk, 

 Plymouth, and Worcester counties led in the number of samples tested, all 

 exceeding 150,000. Middlesex county had the largest number of tests, 224,109. 

 This number approaches the total number of samples tested in the entire State 



13 years ago (1933-34). 



The following breeds were tested: Bantam, Barnevelder, Barred Phmouth 

 Rock, Brahma, Crosses, Dark Cornish, Jersey White Giant, New Hampshire, 

 Rhode Island Red, White American, White Leghorn, White Plymouth Rock, 

 and White Wyandotte. Reactors were detected among the Rhode Island Reds, 

 Barred Plymouth Rocks, White Plymouth Rocks, New Hampshires, and Crosses. 

 The three leading breeds in Massachusetts are Rhode Island Red, New Hamp- 

 shire, and Barred Plymouth Rock. Of the total samples tested 57.7 percent were 

 taken from the Rhode Island Red, 19.3 percent from New Hampshire, and 18.5 

 percent from the Barred Plymouth Rock. The balance was taken from the other 

 breeds listed. 



Of the 1,112,569 samples collected from females, 79,113 were from hens and 

 1,033,456 from pullets. The incidence of reactors was higher among the hens 

 (0.27 percent) than among the pullets (0.11 percent). The 113,025 samples 

 tested from males showed 0.12 percent as reactors. The incidence of reactors 

 among males was about the same as among pullets.
