The National Poultry Improvement Plan became operative July 1, 1935, and the National Turkey 

 Improvement Plan became' operative September 25, 1943, with the approval of the Secretary of 

 Agriculture. On December 3, 1971, the two Plans were combined under one title, "The National 

 Poultry Improvement Plan," with separate provisions applicable to the different types of 

 poultry. 



The Plan operates through an appropriation made by Congress to the United States Department 

 of Agriculture to be used in cooperation with the State authorities in the administration of 

 regulations for the improvement of poultry, poultry products, and hatcheries. Authority for the 

 administration of the Plan is now contained in the Department of Agriculture Organic Act of 

 1944, as amended (7 U.S.C. 429). 



Provisions of the Plan are changed from time to time to conform with the development of the 

 industry and with new information as it becomes available. These changes are based on 

 recommendations made at the Biennial National Plan Conferences by official delegates 

 representing participating breeders, hatcheries, and flockowners from all cooperating States. 

 Current provisions of the Plan are described in a publication entitled "The National Poultry 

 Improvement Plan and Auxiliary Provisions." The publication is available from Official State 

 Agencies or on request to the National Poultry Improvement Plan, APHIS-VS, Room 828, FCB #1, 

 Hyattsville, Maryland 20782.
