Characteristic of a Good Free Choice Mineral Supplement
Modified from McDowell, 1992
1. Supplies minerals and vitamins not supplied by the forage
2. Calculate intake goats 1 oz maybe 2 oz3. Should contain 6-8% total P. Low P soils 8-10%4. Has Ca:P ratio not substantially over 2:1 -4:1
with acidifier like ammonium chloride

Characteristic of a Good Free Choice Mineral Supplement
8. Provides a significant proportion, 50%, of trace mineral requirements for Co, Cu, I, Mn, Zn (Zn, Se, Cu 100% in KY)
9. Locate mineral by water source for improve intake
10.Salt stimulates intake/don’t added more salt

Characteristic of a Good Free Choice Mineral Supplement11.Buy high quality mineral salts providing the best
biologically available forms of each.
12.Must be palatable to insure good intake.13.Backed by a good manufacturer with mineral
supplement label. READ the LABEL.
14.Formulated for the area involved, the environment, temperature humidity (Mg in KY)

Idea II Grazing Plans for 25 acres
•June 1, 75 does for 10 days
•Divide field with Polly-Fence
Tall Fescue and Red Clover
Grazing each paddock for 10 days and rotate
•Graze June-October by rotation•28 days rest / 10 grazing = 3 paddocks + 1 = 4 paddocks

There may be a need for an emergency grazing paddock August and September

Why can this work for you?Plant Energy Levels Are Not Constant
•100% dependent on stored CHO’s
•Decrease until 6-8”
•Return to precut level by early bloom
•Allow 30-35 d rest
•Cut at 2 inches
•Most legumes have similar cycle. For example – Red Clover

Maintain Healthy Root Systems
• Close continuous grazing depletes carbohydrates needed for topgrowth and root growth.
• Regrowth is high quality but there is very little of it.
• Additionally: less drought tolerance, less nutrient uptake, etc…
•Root area decline 30% per year in a continuously grazing system

•Apply nitrogen to ½ of 12 acre block in August 15th for Stockpiled Tall
Fescue
•Graze fescue to maintain vegetative state or make hay August and Sept. •Begin graze 2 paddocks Fescue and Red Clover October 1 and graze •Graze Stockpiled Tall Fescue November-January
•Graze Sericea Lespedeza July-September by rotation•30 days rest / 10 grazing = 3 paddocks +1 = 4 paddocks
