Chairperson: M. F. Hutjens, University of Illinois,
Urbana-Champaign
Whippletree, University Centre
Panel members will speak for up to 5 minutes on each of the following topics to stimulate discussion. Topics and panel members:
- Cation-anion effects on calcium balance. E. Block, McGill University, St. Anne de Bellevue, Quebec, Canada.
- Monitoring herds using urine pH. P. W. Jardon, University of California, Davis.
- Formulating rations to prevent hypocalcemia. G. R. Oetzel, University of Wisconsin, Madison.
- Controlloing potassium in diets. J. P. Goff, National Animal Disease Center, USDA, ARS, Ames, Iowa.
- Oral calcium preparations to reduce hypocalcemia. W. K. Sanchez, University of Idaho, Moscow.
- Where should we set dietary calcium? L. Rodriguez, Michigan State University, East Lansing.
Audience members are encouraged to bring up to 2 slides to help stimulate discussion. Respondents to date indicate they would like to discuss some of the commercial anion sources available and their relative merits, and effects of hypocalcemia prevention on secondary disease prevention. Audience members with slides should contact Dr. Jesse Goff, USDA-ARS, Ames, IA (phone 515/239-8547; e-mail: em:jgoff@nadc.ars.usda.gov) to arrange for projection of slides.
