General Extension Focus

My responsibilities include development of a progressive statewide educational program in swine nutrition that increases the understanding of current nutrition principles, and evaluates feed products that enhance animal performance. Particular emphasis has been on phase feeding recommendations, nutrient management of growing pigs, and the development of future pork producers.

Goals and Objectives

Overall, the success of the MO-Pork and Youth Education programs focuses on promoting Missouri pork production and reducing feed costs on Missouri pork operations. The intended audience is for Missouri pork producers, Missouri citizens interested in pork production and Missouri youth.

The MO-Pork Program

  • Provide educational presentations and on-farm demonstrations on feeding management and other nutritional factors affecting profit, dietary formulations effect on manure nutrients, specific research updates, and product quality issues to Missouri swine producers.
  • Evaluate feed ingredients and products marketed to swine producers.
  • Provide diet specifications and recommendation for swine operations to bid out feed ingredient or complete ration needs.
  • Lower the total cost of production on swine operations in Missouri by reducing feed costs.
  • Improve feed efficiency by minimizing feed wastage, managing feed quality and particle size.

The Swine Youth Program

  • Show Me Quality Assurance.
    • Promote safe and wholesome food for all Missouri youth who exhibit food producing animals (beef, dairy, swine, sheep, goats, rabbits and chickens).
    • Unique opportunity for 4-H, FFA, and the University of Missouri Extension to work together.
  • Pork Institute.
    • Three-day event for high school sophomores, juniors, and seniors.
    •  Learn about careers in the swine industry and compete for two $500 CAFNR scholarships.
    • Nearly 80% of the Pork Institute participants have enrolled at MU focused on a career in agriculture with half active in the swine industry.
  • MO State Fair Skillathon.
    • Competition consists of a software-assisted quiz bowl about current swine production issues, a hands-on laboratory practical, and a 15-minute interview with a swine industry expert from Missouri.
    • Overall scores for the Swine Skillathon competition have increased over the past eight years from an average of 45% in 1999 to an average of 78% in 2006.  These increased scores indicate that participating Missouri youth have improved their overall knowledge of swine production and become more familiar with the swine industry.
  • MO State Fair Growth and Quality Barrow Classic. 
    • Show combines visual appraisal with growth performance and pork quality (pH, color, marbling, and tenderness).
