Foreword

The National Swine Improvement Federation has, as its primary function, developing and implementing more uniform, effective, and coordinated swine improvement programs. Its members include, but are not limited to, seedstock producers, central test stations, swine testing organizations, A.I. studs, universities, and other seedstock production and marketing groups.

Each year the Federation holds a conference and annual meeting during which the impact and application of swine breeding technology are reviewed and updated. The publication of the proceedings of this conference on the NSIF website serves to advance the Federation’s objective of improving genetic evaluation programs.

The 2009 conference and annual meeting were hosted by the NSIF at the Embassy Suites in Nashville, Tennessee. The program of the 2009 conference brought together speakers who spoke within sessions titled Manipulating Input Costs through Improvement of Feed Efficiency, Animal Welfare and the Sow Herd, Factors that Limit Genetic Expression, A New Look at Our Targets, and Perspectives on Research Needs and Emerging Technology. The program brought together a strong academic and industry-based group of speakers to address these topics.

Once again, the symposium and annual meeting were sponsored and very generously supported through the financial contributions of the NSIF Member Organizations. In addition, genetic suppliers, universities, and industry participants played a key role supporting the program through direct financial contributions, committee involvement, and delivery of materials as speakers. The NSIF Board of Directors would like to sincerely thank the following organizations for their support of the conference and annual meeting: Genesus, Génétiporc, Hypor, Inc., Iowa Pork Industry Center, National Swine Improvement Federation, National Swine Registry, Newsham Choice Genetics, PIC USA, and S & S Programming. Without this support, a high-quality symposium would not be possible.

We hope these proceedings will be useful and informative. The Swine Genetics Handbook containing seventeen fact sheets, the Swine Improvement Program Guidelines, and additional information is available at the NSIF web site: http://www.nsif.com. The Swine Genetics Handbook may also be found at http://www.ces.purdue.edu/extmedia/ansci.htm#9.

Elsewhere in these proceedings you will find a list of the 2009-2010 NSIF Officers and Directors. Please feel free to contact these individuals with questions or comments.
