 Alberta Agriculture and Forestry (AF) has revised its Using Animal Unit Month (AUM) Effectively factsheet.

“The concept of the ‘animal unit month’ (AUM) is useful to help range and pasture managers calculate suitable stocking rates for pastures under a wide variety of conditions,” says Karin Lindquist, forage/beef specialist, AF, Stettler. “To optimize the use of available pasture resources, it’s important to understand how the AUM is defined and used. This understanding can help to calculate the best stocking rate to produce the maximum returns without causing damage to grassland resources.”

The factsheet includes sections on defining the animal unit, determining the AUM, differences in consumption rates, and more.

“A land manager can use the AUM definition as a starting point in determining stocking rates, but must remember to make the necessary adjustments to animal size, consumption rates, trampling and spoilage effects to predict realistic disappearance rates,” says Lindquist.

“Coupling these aspects with reasonable estimates on forage production, both as initial growth and re-growth, makes it possible to establish stocking rates for any given range or pasture.”

The newly revised factsheet is available from AF’s website. Hard copies are available from AF’s publications office at 780-427-0391 or via e-mail at publications.office@gov.ab.ca.
