can also be used to determine initial stocking rates. Stocking rate refers to the actual number of animals grazed, which may not match forage production. Jeffery S. Terhune. Table 1. Carrying capacity, tourism Carrying capacity is a concept that has been widely applied in tourism and recreation studies since the 1960s, although some authors trace its emergence to as far back as 1930. Some of these regional differences can be explained by animal movements during the production year. Carrying capacity is how many animals your pasture can support in a period of time. of dry forage Animal unit month AUM 780 lbs. Stocking rate can be calculated from the number and type of grazing animals, and there should be an allowance for native and feral herbivores. cow with calf Animal unit day AUD 26 lbs. The AUM provides us with the approximate amount of forage a 1000 lb cow with calf will eat in one month. carrying capacity of grazing animals on rangelands. In adaptive management, trends in vegetation change are used to adjust the stocking rate of an area according to the management objectives of that area. Stocking rate & carrying capacity . This stocking strategy is based on an assessment of expected market conditions and rangeland capacity for sustainable livestock production, often referred to as grazing capacity or carrying capacity. This report provides the updated potential carrying capacities, methodology used to calculate these and … Carrying capacity in terms of the animal unit (AU) concept. Stocking density is the number of animals on a particular piece of land at a particular point in time. For example, a herd of 30 cows on a 20-acre rotational grazing paddock has a stocking density of 1.5 animal units per acre, even though the stocking rate for the 160 acre pasture remains at 0.75 AUMs/ acre. Carrying capacity is the stocking rate that is sustainable over time per unit of land area. Stocking rate is a management decision of how many cattle to put on the pasture. Another way of calculating the current stocking A major driver of natural resource condition trend is the level of total grazing pressure over time. Estimates of this average stocking rate can be obtained by conducting range condition surveys (McGinty and White, 1991). 10 dry sheep @ 60 kg each in a 2 hectare paddock. Evidence suggests most don’t really understand stocking rate & carrying capacity? Carrying Capacity is how it should be ideally. Improved Utilization of Pond Carrying Capacity by Increasing Initial Stocking Rates and Subsequent Stock Division 1. Thomas E. Schwedler. View Essay - Understanding-Pasture-Stocking-Rate-and-Carrying-Capacity.pdf from ECONOMICS 238 at Harvard University. Carrying capacity is the stocking rate that achieves a targeted level of animal or economic performance over a defined period of time with-out causing deterioration of the pasture ecosys-tem. CARRYING CAPACITY REVIEW Spektrum Review PCC 2018 ABSTRACT This report was commissioned by Landgate to reassess the Potential Carrying Capacity of the majority of the leases in the Kimberley, Pilbara and Southern Rangelands. A critical factor to evaluate is how well the stocking rate agrees with the carrying capacity of the land. i.e. QUICK DEFINITION: Stocking Rate is defined as the amount of land allocated to each animal for the grazable period of the year. A sustainable stocking rate is one which does not degrade the natural resources or permanently reduce pasture productivity as a result of overgrazing, species loss and weed growth. Managing grazing pressure so that a negative trend in condition is avoided requires an understanding of the carrying capacity of your property and individual paddocks and how these differ to stocking rates. 1 AU / 15 Acres How many cows will your land support in Texas? Both involve matching pasture supply to cattle feed intake requirements. This AUM was established to be 800 lbs of forage on a dry weight basis (not green weight). Thus, carrying capacity is set by mother nature, through soil and climate characteristics; stocking rate is set by humans, through livestock or wildlife management. It takes into account the mix of land types, their condition, the climate and animal production and land condition objectives. It has been defined as an ox which weighs 450 kg and which grows at 50 g per day on a grazing field which are 55% digestible. Carrying capacity and stocking rate.
