 from eggs obtained from any other locality.

National Poultry Improvement Plan (R. C. Durgin and David Flagg) 



Record of Performance. During the past year, 13 flocks, consist- 

 ing of 7,576 chickens, were entered in the United States Record of 

 Performance program. Of this number, 1873 birds, or 32 per cent, 

 qualified for certificates. To meet the Record of Performance re- 

 quirements for certificates, birds must lay a minimum of 200 stand- 

 ard-sized eggs in a laying year. 



United States Approval and Certified Stage. This year 44,305 

 birds were banded and selected according to the requirements of the 

 United States Approval Stage of the National Plan. Eighteen flocks 

 were approved, as compared with eight flocks in 1939-40. Nine flocks 

 met the requirements of the United States Certified Stage, as com- 

 pared with two flocks last year.

 Poultry Autopsies 



Autopsies were made on 2913 specimens, consisting chiefly of 

 adult chickens, chicks, adult turkeys, and poults. Among the 1534 

 adult chickens examined, the most prominent diseases were blue 

 comb, ruptured egg yolk, and traumatism. With chicks, the major 

 diseased conditions were naval infection, chronic coccidiosis, ulcer- 

 ated gizzard, and pneumonia. Blackhead and omphalitis were the 

 principal diseases found among both the adult and the young turkeys, 

 although cases of many other diseases were found.

Pullorum Testing 



Among the 782,626 birds (chickens and turkeys) tested for pul- 

 lorum, 336 reactors, all females, were segregated. The largest per- 

 centage infection was found among the White Plymouth Rocks, 

 0.264 per cent of which were reactors. The Barred Plymouth Rocks 

 had 0.017 per cent infection, and the New Hampshire's, 0.045 per cent. 

 The other breeds tested showed no reactors, and all turkeys tested 

 were free of the disease.

 Textile Research Project 



Interest and cooperation in a textile research project conducted 

 by home economics research workers continued through 1940, al- 

 though not a large number of samples have been secured. To date, 

 there have been 83 pieces of material sent to State College, Pennsyl- 

 vania, for testing purposes, 



The ultimate reason for making this study is to find (1) what per- 

 formance can be expected of textile fabrics of different constructions 

 and dyed with different dyes, and (2) what changes, if any, should 

 be made in present methods of testing fabrics in the laboratory, so
