Quick Links . Grazing Calculator (Free app) from North Dakota State. The construction of a single series of index values based on different variables for different plant groups is inappropriate. The NDSU Grazing Calculator helps land manager/owner estimate carrying capacity and set initial stocking rate for their grazing resources. Background . Next, estimate the number of animal units that could be stocked on the pasture given the above forage production potential. Long-term carrying capacity refers to the average number of animals that a paddock can support over a planning period (5-10 years) and depends on the: Mix of land types. CALCULATION. What we have learned from stocking rate studies.

This calculation is then compared to a table of values representing each type of animal and their AU equivalencies (for example, an adult horse is equivalent to 1.25 AU). Category: Uncategorised. Grazing capacity calculation . Long-term carrying capacity. Carrying capacity calculated in this way was found to be a fair reflection of actual observed stocking rates. Stocking rate is how things are, good, bad or ugly. Online Forage Calculators These calculators explore the number and type of livestock your land can support based on forage need and the forage available. Calculate grazing capacity: Grazing capacity = forage supply ÷ forage demand/cow = 261,000 kg ÷ 2,920 kg/cow = 89 cows/year. Updated. Evidence suggests most don’t really understand stocking rate & carrying capacity? Grazing capacity integrated with reforestation..... 24 APPENDIX 3. The calculation of the LTCC for a property (land parcel or land parcel) is based on a number of factors, including: the long-term median annual native pasture growth; the safe utilisation rate of the pastures; the property topography and tree density. The only time that the value of veld or grazing directly correlates with carrying capacity is in budget calculations. Calculations were made based on the dry matter yields and closure rates of the kermes oak in the study. The most accurate method to calculate forage production is the clip-and-weigh method. Estimate Stocking Rate, Expenses, and Total Return – represent the grazing capacity; P.V. OR To extend your grazing season (ie, add more days), you may choose to graze for a limited number of hours per day. of Forage DM . Whenever I’m talking to a grazing group or event, I always ask who knows what these numbers are. Look for obvious signs of grazing and cattle activity at a number of points away from water and work out the furthest point cattle range. Anonymous National Anti-corruption Hotline: 0800 701 701. However, the opportunity to graze ewes on lucerne needs to be compared to other option such as finishing lambs or growing weaners during the summer/autumn months. Stocking rate Conversions..... 25 3. It can vary from year to year on the same area due to changes in forage production. In reality, this calculation does not allow carrying capacity to be fine-tuned to a very specific number of animals. If SR equals GC the rangelands are properly grazed, but if SR does not equal GC then grazing is improper and irrational and should be adjusted. The stocking rate calculator is designed to determine the number of cattle or sheep you should put into a paddock based on its carrying capacity. T o determined the relationship between rangeland condition. Carrying capacity is a measurement of how much forage a unit or piece of ground is able to produce on an average year. It also explains the process for map development and related carrying and grazing capacity procedures in GLIMPS. x c were: G.c. Carrying Capacity is how it should be ideally. scripts. However, it important not to include areas that are outside a realistic grazing distance from water. Research by Botha (unpublished report, 1991), revealed that the index values currently used to calculate the veld-condition score, may lead to either over- or under-estimation of the current grazing capacity. a.
