AGN370 Forages Name:

Forage/Grazing Stick Estimates

In this exercise you will estimate the quantity of forage available in a paddock. Use your textbook and notes to make your decisions.

  1. You want to renovate this pasture to a novel endophyte tall fescue + legume pasture. Explain what you will need and describe your goals. See attached soil test results.

To renovate the pasture you must destroy the existing stand, figure out forages for spring and fall seedings, also prevent seedhead production with the existing infected stand of toxic endophyte.

  1. Field size estimate: ___________________ ft2 ÷ _________ft2/A = _____ acres

Field limitations or problems? (e.g. slope, wet areas, etc.).

  1. What are your recommended (see Southern Forages, table 12.1):

    1. Seeding rate

    2. Seeding date

    3. Seed bed preparation

    4. Amendments (one time vs annual?)

    1. Anticipated problems/solutions

Use the formula below to estimate the number of days you could graze four 600 lb steers (i.e. “stockers”) on this paddock. Assume you have 8 pastures (paddocks) of similar productivity.

Days = Total lbs Forage/Ac x Ac x % Grazing Efficiency

Avg animal Wt. x intake rate in % Body Wt. x animal number
