What is AUM on ranch?
An AUM is the amount of air-dry forage a 1,000-pound cow and her un-weaned calf will. consume (the ‘Animal Unit’) in one month. The AUM was developed in the mid-twentieth century when average cow weights were closer to 1,000 pounds than today’s weights.
How many Aum is a yearling?
0.67 AU
Various other types of stock are assigned AUM equivalents based on size and consumption. For example, a mature bull is the equivalent of 1.3 AU, a yearling steer or heifer is 0.67 AU and a weaned calf is 0.5 AU. These are equivalents established by the discussions of various agencies specializing in range management.
How many AUMs is a horse?
Wild horses have what is called an Appropriate Management Level (AML) of 12,811 that translates to 153,732 AUMs.
How do you calculate AUM cattle?
AUM is based on an animal intake of 2.5% to 3% of body weight per day on a dry matter basis, that is adjusting for moisture content of feed. For example: A 1,000-pound cow eating 2.5% of its body weight eats about 25 pounds per day (1,000 pounds x 0.025).
What does AUM stand for in cattle?
Animal Unit Month
An Animal Unit Month (AUM) is the amount of forage required by one animal unit for one month. The Natural Resources Conservation Service (NRCS) uses 30 pounds of air-dry forage per day as the standard forage demand for a 1,000- pound cow and her calf (one animal unit).
What is AUM pasture?
Stocking rate is the number of animals on a pasture during a month or grazing season, and is usually expressed in animal unit months (AUM) per unit area.

How much acres does a horse need?
two acres
In general, professionals recommend two acres for the first horse and an additional acre for each additional horse (e.g., five acres for four horses). And, of course, more land is always better depending on the foraging quality of your particular property (70% vegetative cover is recommended).
Is an acre enough for a horse?
If you are attempting to figure the carrying capacity of land for a horse, then a good rule of thumb is 1-1/2 to 2 acres of open intensely managed land per horse. Two acres, if managed properly, should provide adequate forage in the form of pasture and/or hay ground. But this is highly variable depending on location.
What is AUM in range?
The animal unit month (AUM) concept is the most widely used way to determine the carrying capacity of grazing animals on rangelands. The AUM provides us with the approximate amount of forage a 1000 lb cow with calf will eat in one month.
How much is an AUM?
Online Tuition & Fees Tuition for non-Alabama residents enrolled in fully online programs $353 per credit hour for undergraduate classes and $463 per credit hour for graduate classes. All students taking online classes at AUM are assessed the Online Course Fee of $40 per credit hour.
How many acres do you need per cow in Texas?
Stocking Rates in Texas vary from 1 cow per acre on heavily managed pasture in the Eastern portion of the state to 1 cow per 150 acres (4 cows per section) in the Trans Pecos Region of the state.
What does Aum mean in cattle?
Animal Unit Months. Often grazing plans and recommendations use terminology such as Animal Unit Months (AUMs) to describe the carrying capacity of a given forage or pasture. This is simply a system used to standardize the forage needs of cattle and the forage available. In this system, a 1000 lb. animal is considered 1 AU making a 600 lb.
What are animal unit months (AUMs)?
Often grazing plans and recommendations use terminology such as Animal Unit Months (AUMs) to describe the carrying capacity of a given forage or pasture. This is simply a system used to standardize the forage needs of cattle and the forage available.
What is Aum and why is it important?
Such an understanding can help in determining stocking rates to produce the maximum returns without causing damage to the available grassland resources. By definition, the AUM is the amount of forage needed by an “animal unit” (AU) grazing for one month.
How can Aum be used to determine stocking rates?
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.
