Pasture Stocking Rates
Damon Pollard, Extension Agent, Livestock
Stocking rates are positively related to forage health. Overstocking stresses forage
stands and eventually leads to low producing pastures.
When talking about pasture stocking rates, we can lump all livestock together by
converting them into the concept of an animal unit. An animal unit is based on the
beef cow and her calf, which is one animal unit. The bull is also one animal unit, as
is one horse. Sheep and goats, due to their small size, take 6-8 head to equal one
animal unit.
It generally takes 2-3 acres to support one animal unit in hay and pasture. If hay is
cut elsewhere and brought in it reduces the acres needed. Acreage needed can also
be reduced through improved pasture management and improved forage varieties.
A really good manager can support one animal unit on an acre and a half.
Stocking rates as high as 2 animal units per acre are present in Burke County, and
not even weeds can produce in this setting. Two acres per animal unit allows
producers to mitigate drought and reduce hay feeding days as more grazing days
are available and forage could be stockpiled.
Pasture management is more complex than just putting the right number of head on
the right number of acres, however, getting the stocking rates right is basic to any
good management system.
