Accomplishments
Report from Paul Rodgers, American Sheep Industry, Association. Paul thanked the committee for the opportunity to meet with them and to continue the association between the National Sheep Improvement Program (NSIP) Technical Committee meeting and NCR-190.
The article summarizing the findings of the cooperative project conducted by committee members, Length of docked tail and incidence of rectal prolapse in lambs, was written by D. Thomas and has been submitted to the Journal of Animal Science. Two other publications summarizing the cooperative efforts of NCR-190 members on: Crossbreeding K. Leymaster, and Out of Season Breeding D. Notter are also in the final stages of review. Both of these articles will be published in a special issue of the Sheep and Goat Research Journal. Following publication there, Leymaster and Notter will take the initiative to edit the articles as necessary for further publication and distribution in industry channels including popular press magazines, ASI newletter, and electronic media options.

Impacts
- Collaborative research on tail dock length has been conducted and summarized, and is being disseminated to academic and industry audiences.
- Research conducted and published by this committee constitutes the national resource for implementation of out-of-season breeding.
- Communication with the American Sheep Industry Association has resulted in the definition of timely crossbreeding research objectives.
