Forage Quality Matters

• Low 40-55 % TDN

• Good 55- 70 % TDN

• Concentrates 70-90 % TDN

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)

15.Monensin or Decox additives

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

•6.25 ac

•6.25 ac

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

Delay in Maturity and Enhances the Vegetative State

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

Idea III Grazing Plans for 25 acres


•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

•Drill annual ryegrass in to SL Sept. 1
