infectious Bronchitis Vaccine 



Commercial vaccines for preven- 

 tion of infectious bronchitis of 

 poultry are not being manufactured 

 due to federal regulations against in- 

 terstate shipment. For this reason, the 

 poultry laboratory produces bron- 

 chitis virus for the poultrymen of the 

 slate. This material is produced in 

 embryonating eggs and packaged in 

 lots of sufficient quantity each for a 

 flock inoculation. It is held frozen at 

 approximately -10°F. During the 

 period from July 1, 1949 to June 30. 



1951, 1,768 lots have been supplied 

 to New Hampshire flocks.

The NPIP Meat Program is an at- 

 tempt to evaluate the meat qualities 

 of different strains and breeds of 

 birds. Of the 10 flocks participating 

 in the United States, New Hampshire 

 has half of them. This program 



measures egg production of the par- 

 ent strain, as well as meat qualities 

 at broiler age. It has led to the es- 

 tablishment of the First New Hamp- 

 shire Broiler Test where the chicks
