1) An announcement was made that station reports were to be filed within 60 d of the meeting.
2) Due to a catastrophic hard disk failure, the proposal must be reconstructed. This effort was to be performed by D. P. Froman with detailed input from members. Input was requested by November 30th. Proposal reconstruction would begin in December 2005.
3) The proposed site for the 2005 meeting was Las Vegas, Nevada. Tentative meeting dates were identified: October 27 and 28 or November 3 and 4. Jim Milam agreed to host the meeting.
DC305 was formed for the purpose of transitioning between S-285 Reproductive Efficiency of Turkeys into a regional project that addressed reproductive efficiency of poultry in general. This goal was realized as evidenced by retention of core scientists who participated in the prior project and the addition of new scientists whose specialties enhance the expertise of the group. As such, the group of scientists within the new project have the capability of addressing the range of problems encountered in commercial poultry reproduction, which includes laying hens and broiler breeders in addition to turkeys. While fundamental expertise was retained with respect to the study of photorefractoriness and broodiness in turkeys, significant expertise has been added with respect to broiler breeders. This is noteworthy due to the per capita consumption of broiler meat within the U.S.
- The intended outcome of DC305 is the preparation of a new regional project to be completed in early 2005. The potential impact of this effort will be the formal alignment of the foremost U.S. scientists who study poultry reproduction, a biological process that underlies a multi-billion dollar industry within the U.S.
None as the objectives of DC305 was the development of a new multistate project as opposed to the completion of experimental objectives as evidenced by peer-reviewed journal articles.
