1 Range Condition & Stocking Rate

2 Range Condition Determining the health of a range Need to know: –Region (Eastern Glaciated Plains) –Range Site (Thin Silty) –Plants Present and amounts of each in percent Place plants in correct categories on worksheet Rule out any invaders Determine maximum allowable per plant

3 Determine the Range Condition Eastern Glaciated Plains “Clayey” Range Site Bluebunch Wheatgrass25% Green Needlegrass20% Plains Muhly15% Smooth Brome10% Western Yarrow10% Drummon Milkvetch10% Rubber Rabbitbrush10%

4 Determine the Range Condition Complete Range Condition Worksheet Fill in plants and percentages that are present

6

7 Range Condition Determine the Total Percent of plants you are allow to have Put these maximums in the second column of the worksheet Determine Condition –Poor = 0% - 25% –Fair = 26% - 50% –Good = 51% to 75% –Excellent = 76% - 100%

9 Determine the Range Condition Determine the Adjusted Maximum Percentages Allowed Choose the “smaller” number of the first two columns and place in the last column

11 Determine the Range Condition Determine Range Condition Rating –70% Determine the Range Condition –Good Complete Stocking Rate Problems

12 Terms Animal Unit = forage consumption of a 1,000 # cow (dry or with calf) –all other animals are compared to a cow –Bull & Horse = 1.25 AU –Sheep =.2 AU Animal Unit Month (AUM) = amount of forage required to feed one AU for one Month

13 Calculating Stocking Rates AUM’s/acre X Acres = Total AUM’s.2 AUM’s/acre x 1000 acres = 200 AUM’s 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 Calculating Stocking Rates 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

15 Calculating Stocking Rates How many cows along with 50 sheep and 4 horses for 4 months? AUM / M = AU 200 / 4 = 50 AU 50 AU = (50 x.2) + (4 x 1.25 ) + cows 50 = 10 + 5 + cows 35 = cows
