  15. Forage Production

  16. Pasture Productivity

  17. Pasture Productivity

  18. Forage Production • DBH should range from about 50 to 65 ft/ac to help ensure stand longevity and maximized productivity. • Silvopasture produces about 60% of the dry matter of equivalently managed open pasture.

  19. Herbage Quality

  20. Herbage Quality • With too little sunlight: plant crude protein can be excessive, nitrate level can be high, sugar content is low, and energy content is not balanced with protein. • Resulting in: decreased intake, lowered performance, and possibly animal loss (high nitrate). • Adequate light penetration a must.

  21. Animal Response

  22. Lamb Performance

  23. Summary • Silvopasture produces about 60% of the dry matter of open pasture. • Animal performance is similar between pasture types, with lambs achieving 0.20 lb ADG under our management scheme.

  24. The authors thank Danny Carter, Matt Huffman, Joe Ketz, Mark Peele and Joyce Ruckle for their: diligent work, invaluable design discussion, lab and data analysis, and presentation help.
