Laboratory. These represented 1,072 

 cases. 



A total of 2,393 birds were ex- 

 amined. There were 933 cases of 

 birds other than turkeys; the remain- 

 der of the specimens consisted of 154 

 turkeys (68 cases) and 196 Miscel- 

 laneous (71 cases). 



In addition to those mentioned, 

 98 Hemagglutination Inhibition tests 

 for Newcastle disease were run on 

 pooled flock sera obtained from the 

 pullorum samples. Three of these 

 proved to be positive for Newcastle 

 disease. The Newcastle work was 

 not staarted until April 1948.

The National Poultry Improve- 

 ment Plan. The National Poultry 

 Improvement Plan became operative 

 July 1, 1935 under the sponsorship 

 of the Federal Government with the 

 co-operation of the states on a vol- 

 untary basis. Acceptance of the plan 

 is optional with the individual. That 

 the plan has met with general accept- 

 ance is now evidenced by the fact 

 that it is in operation in 47 states. 



The chief objectives of the plan are 

 to improve the breeding and produc- 

 tion qualities of poultry, to reduce 

 losses from pullorum disease, and to 

 identify the quality of breeding stock, 

 hatching eggs, and baby chicks with 

 uniform terminology applicable 

 throughout the country. In New 

 Hampshire, the plan is administered 

 by a board of 10 active poultrymen 

 with the co-operation of the Univer- 

 sity of New Hampshire, the Agricul- 

 tural Experiment Station, and the 

 State Department of Agriculture. 



During the past year, 290 poultry- 

 men owning 813,766 birds partici- 

 pated in the various breeding stages 

 of the plan in New Hampshire. In 

 addition, 357 poultrymen, owning 

 573,029 birds,, participated in the 

 pullorum eradication stages but not 

 in the breeding stages of the plan. 

 Fourteeen poultrymen have flocks 

 participating in the Record of Per- 

 formance breeding stage of the plan. 

 These flocks contain 6392 R.O.P. 

 candidates under trapnest and 148 

 special mating pens containing 2061 

 R.O.P. females.
