There were 10 flocks of the 203 flocks tested in which infection was 

 found, as compared to 23 infected flocks the previous season. 



Of the flocks in which infection was found. 4 flocks had been tested 

 100% for two or more consecutive years and of these flocks two were Pul- 

 lorum Accredited (two or more lOO^o tests — no reactors) and two were 

 Pullorum Free (one 100% test — no reactors). Of the formerly Pullorum 

 Accredited flocks .8 of 1% of the 1,901 birds tested were reactors. There 

 were .07 of 1% reactors of the 3,866 birds tested in the two formerly Pull- 

 orum Free flocks. 



Five flocks testing all birds for the first time showed 12.8% of the 2,582 

 birds as reactors. One flock testing only part of the flock had 1.6% of the 

 298 birds which were reactors. There were no reactors found in the 14,643 

 males tested. (C. A. Botforff and C. L. Martin — Miscellaneous Income.) 



Record of Performance Report 



New Hampshire poultrymen, in spite of troubled times, have shown a 

 decided interest in better breeding, and more trapnesting and pedigree work 

 is being done than ever. Record of performance work, which is merely offi- 

 cially supervised trapnesting and breeding, has kept pace with this trend. 

 Through the medium of eight annual inspections by a representative of the 

 Experiment Station the breeder secures official recognition of his records. 



Developments in Record of Performance this season include an increase 

 in membership to nine breeders (1 of Barred Rocks ; 1 of White Rocks ; and 

 7 of New Hampshire Reds). A major change in rules has been made to 

 give recognition to the breeding value of individual birds, taking into con- 

 sideration the performance of the progeny of an individual mating. Minor 

 changes in rules, involving egg weights and body weights, have also been 

 made. 



Results of the third season of Performance show 1,608 birds entered in 

 the project, 272 meeting the requirements for R.O.P. Certificates (200 eggs 

 or over, 24 oz. in size) ; 106 birds winning advance certificates (240 eggs or 

 over, 24 oz. in size). A total of 378, or 23.5%. This shows progress over 

 previous seasons' averages of 22.12% for 1931-32. and 23.4% for 1932-33.

Certification of Poultry 



There were 16,066 birds handled for certification during the period July 

 1, 1933 to July 1, 1934. Certification work entails the handling of a flock by 

 a member of the Experiment Station staff and grading the birds into classes 

 of breeders, layers and culls. 



Due to changes in the terminology of the poultry Hatchery Code, the 

 work will be known in the future as "Approval" rather than "Certification."

Distribution of Fowl Pox Vaccine 



The Poultry Pathology Laboratory distributed a total of 274,800 doses 

 of fowl pox vaccine during the fiscal year. New Hampshire poultrymen 

 used 254,200 doses, an increase of 62,650 doses over the previous season.
