• 1 Animal Unit (AU) = 1,000 lbs
  • 25 lbs feed/day per 1 AU
  • Sheep & Goats (mature) = 1/7 AU = 3.5 lbs feed/day
    • I think 0.2 for sheep is better = 200 lbs.
  • Lambs & Kids = 1/14 AU = 1.8 lbs feed/day
  • 1 sm sq bale = 50-75lbs / 3.5lbs = 14-21 days

Wintertime Feeding

  • 5/7 AUs (3 sheep, 2 goats)
  • = 18 lbs/day = 1/3 bale/day = 11 bales/mo
  • x 6 months = 66 bales for winter

Land Production (as of 2015)

  • 28 large sq bales (1 missed cutting, allowed for)
  • 15 sm sq per 1 large bale = 420 bales
  • / 3.5 acres = 120 bales/acre (up to 180) per year
  • - half to farmer
  • = 210 sm sq bales  each yr (up to 315 3rd cutting)

Grains/Supplements

  • Goats: Corn, minerals, molasses mix = 1 handful per day (1/2 lb) per goat
  • Sheep: Sheep feed = 1 lb per day per sheep (#8 can = 3 lbs)
  • #/yr?

Pasture Stocking for Intentional Managed Grazing

  • 3.5lbs/day * 4 sheep = 14 lbs/day
  • 1.8lbs/day * 4 lambs = 7 lbs/day
  • Total ~ 20 lbs/day
  • Land production = 10 large sq bales / acre = 7,500 lbs/acre
    • / by 5 Months (May – Sep) = 1,500/month
    • / by 30.5 Days = 50 lbs per day per acre
    • Reverse Calc: 50 lbs = 1 sm sq bale * 150 days (5 months) = 150 small squares
    • 150 / 15 sm sq = 10 large sq per acre (checks out)
  • 50 lbs per day per acre, need only 20 lbs per day per acre = 0.4 acres for the herd

Managed Intensive Rotational Grazing (MIRG)

  • 33,333 lbs/acre (33 AU/ac)
  • 1-day rotation
  • 165 sheep/acre (1 Sheep = 0.2 AU)

Ultra High Density Stocking (UHDS) or MOB Stocking

  • 100,000 lbs/acre (100 AU/ac)
  • 8-hour rotation
  • 500 sheep/acre

Modified MIRG for 4 sheep

  • 33,333 # / Acre = 165 Sheep / Acre (Using 0.2 AU)
  • 1,320 sq ft / 1 AU animal = 264 sq ft per sheep per day
  • 3-4 day rotation = ~900 sq ft per animal * 4 = 3,600
  • 3,600′ = 60’x60′ paddocks (rotational paddocks should be square as possible)
  • Requires 10 paddocks to achieve 29-day rest period
    • Paddock 1 = Day 1 – Mon
    • Paddock 2 = Day 4 – Thurs (Paddock 1 rests)
    • Paddock 3 = Day 8 – Mon (P1 = 5 days)
    • Paddock 4 = Day 11 – Thurs (P1 = 8 days)
    • Paddock 5 = Day 15 – Mon (P1 = 12 days)
    • Paddock 6 = Day 18 – Thurs (P1 = 15 days)
    • Paddock 7 = Day 22 – Mon (P1 = 19 days)
    • Paddock 8 = Day 25 – Thurs (P1 = 22 days)
    • Paddock 9 = Day 29 – Mon (P1 = 26 days)
    • Paddock 10 = Day 32 – Thurs (P1 = 29 days)
