Calculating Stocking Rates

• AUMs/acre X Acres Total AUMs
• .2 AUMs/acre x 1000 acres 200 AUMs
• How many cows can you run for 4 months?
• AUM / M AU
• Answer 200 / 4 50
• How many months can you run 25 cows?
• AUM / AU M
• Answer 200 / 25 8 months

14

• How many months for a herd of 50 sheep and 10
  cows?
• AUM / AU M
• 200 / ((50 x .2) (10 x 1)) 10
• How many cows along with 4 horses for 2 months?
• AUM / M AU
• 200 / 2 100 AU
• 100 AU (4 x 1.25) cows
• 100 - 5 95 cows
