We must look at stocking density as animal concentration and a tool used to accomplish our goals of intensive grazing management. Registered in England and Wales. Stocking rate is the number of animals on the pasture, while carrying capacity is the number of animals the pasture will support year after year while achieving an acceptable level of performance. Stott writes, “The productivity of a given piece of land is dependent on site characteristics which vary with location. Think of stocking rate in terms of either animals per acre or liveweight per acre. Informa Markets, a trading division of Informa PLC.

Nix, … Note that stocking density applies only to grazing animals; it does not involve hay or silage or fallow land. Stock density is essentially animal concentration, and is a tool we use to accomplish many management goals in MiG. Stocking rate is often used interchangeably with carrying capacity, which is also incorrect. All rights reserved. Management of stocking density is one such relationship between grazing cattle and pastures. Dry sheep equivalent and stocking density A DSE is used as a method of standardising an animal unit and is the amount of feed required by a two year old, 50kg Merino wether to maintain its weight. Then, calculate the stocking rate as before. Although the research was done in the USA, we can still make use of the recommendations with little or no adjustment to suit our tropical environment and African catfish that we culture in our region.

For most pastures, most stocking rates are typically calculated using a 50 percent utilization rate, or "take half, leave half." Dairy producers overstock to save building costs per cow or when growth exceeds capacity to build new facilities. Stocking rate is measured in terms of dry sheep equivalents (DSE). You can find out more about pasture utilisation for cattle producers in the MLA More Beef from Pastures pasture utilisation module. A particular area of the pasture is only being grazed 2.5% of the time and rested 97.5% of the time. Jim Gerrish is a grazing management consultant based in May, ID, and former lead pasture researcher at the University of Missouri's Forage Systems Research Center in Linneus. For example, if 30 cows weighing 1200 pounds were grazing for six months, the forage demand equation to calculate Animal Unit Months (AUM) demand would look as follows: 1.2 AUE x 30 head x 6 months = 216 AUM’s.

But we can't automatically double or triple carrying capacity by embracing the newest fad in grazing management. Now, every acre is being rested 90% of the time and grazed 10% of the time. Any tool also can be used to smash a fine cabinet to pieces in the hands of someone ignorant of its intended use. A sustainable stocking rate is … In each of these scenarios, the stocking rate hasn't changed but animal impact has changed profoundly. Now let’s talk about “stocking density.” We define stocking density as the amount of biomass grazing a given area at a single point in time, expressed as pounds per acre. Each hundred pounds over or under the 1000 pound baseline is either an addition or subtraction of 0.1 (e.g. Livestock units and stocking rates. Registered in England and Wales. “With forage production and amount of forage consumed per month per head, we can now calculate the AUM’s for availability.

High stock density is a tool to achieve more uniform grazing with less selective grazing, a high utilization rate on stockpiled forage, manipulate species composition of a pasture, accelerate the nutrient cycling process, and a host of other management factors. Animal size is taken into account using an Animal Unit Equivalent (AUE). It determined that market cattle can probably be stocked at 35-37 square foot per steer in hoop barns, with no affect on carcase characteristics. Stocking rate, carrying capacity and stock density are expressed as number of animals or animal liveweight/acre. To calculate stall stocking density (%) the number of cows in the pen and the number of useable stalls were counted and multiplied by 100, and the length × width of the pen was divided by the number of cows in the pen to calculate area/cow (m(2)).

In the article, Stott provides links with videos that further explain how to calculate stocking rates, as well as a demonstration on how to use the hoop method to calculate pounds per acre. Utilizing alternative feeds such as distillers grains, wheat midds or corn are cost-effective methods of stretching hay supplies.". Stocking Rate Calculator Step 1. Most ranchers aren't there yet, In a recent UNL Beef Watch newsletter, Stott explains, “Calculating forage demand captures three important elements: animal size, length of time grazing and number of animals. Livestock Units(LUs) are a way of comparing the nutritional requirements of grazing animals.They therefore assist with the calculation of stocking densities. This is our availability.”. Regarding the 100 steers on 100 acres scenario, if the pasture is continuously grazed with animals potentially present on every acre every day, stocking rate and stock density are the same: one steer/acre or 700 lbs. The stocking density of Florida pastures can impact beef cattle production, forage production, and enterprise profitability. An acre of land will only produce so much forage and support only so many livestock. However, there is considerable variation in … Stock density is now 7,000 lbs./acre. Stocking rate or Carrying Capacity The number of cattle carried in a paddock or on a property - usually expressed as the number of cattle or breeding units per hectare. How to manage stocking densities: Ensure you always remain compliant with stocking density limits. Current stocking density: Stocking density worked out using eligible land and farmed grazing livestock numbers in the LFASS claim year. *Rotation frequency recommendations are based on a 25 day rest period for each paddock. Clipping forage inside the dimensions of a small frame or hoop is the most common method for determining forage production if no previous production records exist. Beef stocking rates and farm size hunter region. The farm stocking rate (DSE/ha) = number of stock of each class x DSE per head, divided by the number of hectares on the farm. Remove cattle from cornstalks when soils begin to thaw, Cover crops offer potential grazing benefit for cattle operations. Enter new feeds not on the list as long you know the DM, ME and CP values. I've heard stock density described as a hammer. Expressed Carrying Capacity: AUM ÷ total acres ÷ AUE5 = AUEM/ac 1 Relative production value (Table 4). We're delivering 10 times the animal impact on an acre as before, but staying there for less time. Regarding the 100 steers on 100 acres scenario, if the pasture is continuously grazed with animals potentially present on every acre every day, stocking rate and stock density are the same: one steer/acre or 700 lbs. “After clipping, forage should be dried (for calculating on dry matter basis) and weighed in grams (remember to take into account weight of sample bags!

Total Land Area ÷ [(# AUs) x (grazing season)] = Stocking Rate 100 ÷ (60 x 6) = 0.27 acres per AUM or 1.7 acres for the season. For example, if 30 cows weighing 1200 pounds were grazing for six months, the forage demand equation to calculate Animal Unit Months (AUM) demand would look as follows: 1.2 AUE x 30 head x 6 months = 216 AUM’s. If we have 100 acres and 100 yearling steers weighing 700 lbs., the stocking rate is one steer/acre or 700 lbs. an 1100-pound cow equals 1.1 AUE). The livestock density index measures the stock of animals (cattle, sheep, goats, equidae,pigs, poultry and rabbits) converted in livestock units (LSUs) per hectare of utilised agricultural area (UAA).. Stocking rate affects the pasture's overall productivity, species composition, likelihood of soil compaction occurring, individual animal performance, and a host of other factors in the pasture-livestock relationship. The applied stocking rate on any section of land allocated to a particular flock of sheep or herd of cattle, is usually expressed as x - number of hectares per animal, since the capacity of the natural pastures of South Africa to carry stock is so low on account of the low … One DSE represents the energy requirement of a non-lactating 50 kg ewe at maintenance; 8.3 megajoules metabolisable energy per head per day (MJ ME/hd/day). If we build on the previous example, we have the same 100 acres, now split into ten, 10-acre paddocks for our 100 650lb stockers. However, if the plant density is lower than 75 percent and forage height is 6 inches (15.2 cm) or less (a short, thin stand with a bit of bare ground showing between plants), the utilization rate should be low, such as 25 or 30 percent. Calculate total “available” forage by using the “take half, leave half” method, either divide total production by 2, or multiply by 0.5. Share with us in the comments section below. How is the grazing season shaping up in your neck of the woods? The changes to stocking density are not as simple as 0.3 LU/HA.
