The kind, class and size of livestock will … Livestock stocking rate impacts not only a livestock operation and operation economics, but impacts wildlife habitat as well. 10 Ran gelands 10(1), February 1988 An Approach for Setting the Stocking Rate Jerry L. Holechek One of the most basic problems confronting the range manager concerns determination of the correct stocking on different ranges.Although this problem has received consid- erable attention since the beginning of scientific range man- agement in the early 1900's, specIfic procedures or approach- Researchers Study Modified Intensive-Early Stocking Rates. When forage is reduced below threshold levels, rainfall doesn’t infiltrate the soil as deeply and animals don’t perform as well. The most common cause of degradation is simply that ranchers expect animal productivity from their rangelands to be much higher than is realistic (Pressland and Graham, 1989). OR: My stocking rate is 640 acres ÷ 385.2 AUMs = 1.66 acres per AUM. Once stocking rate decisions are made, they should be implemented as soon as appropriate. 191-199. Pinchak, W. E., S. K. Canon, R. K. Heitschmidt and L. Dowher. I could easily do a cow/c per 1.5-2 acres. This is always the same number, .04, or 4%. 0000005039 00000 n Thus, when properly stocked, rangeland will achieve about a 25 percent harvest efficiency (25 percent actually consumed by livestock). 1991. Stocking rates refer to the number of stock, e.g. Stocking rate is the number of animals per unit area of land. The daily forage consumption of an animal unit is 17.64 pounds. The ability to calculate stocking rate and make timely management decisions is vital At the same time, projected forage demand in the coming months can be determined and compared to the forage supply to determine if adequate forage is available. Terminology for grazing lands and grazing animals. Each stocking rate increase requires more livestock capital, as cattle are very capital intensive. Coffey said that increasing stocking rate by 0.8 of a cow per hectare, with a minimal increase in supplementation, produced an extra 264kg/ha of milk solids. A second approach to quantifying forage production is to monitor the disappearance of range forage by comparing grazed areas with small, fenced areas which are left ungrazed (Figure 7). This equals 12.8 animal unit days of grazing per acre (225 divided by 17.64 pounds per day) before grazing must be stopped until regrowth occurs. Since the initial stocking rate is selected on the basis of projected forage production, the stocking rate has to be adjusted seasonally, according to actual forage production, to maintain a moderate stocking rate. The stocking rate for grazing animals is a crucial decision which affects the rangeland and, therefore, the success of the ranch. Stocking rate refers to the actual number of stock per unit area at a particular time. The process of estimating annual forage production becomes easier if a rancher gathers historical data and pays attention to trends. Ungrazed herbage is an investment in future forage production. The use of the range affects all other ranch resources, the achievement of goals and the sustainability of the ranch. Range Term Glossary Committee. Sustainable Stocking Rate Animal Unit Month (AUM) Beef Cattle Grazing Management Livestock Rangeland Management Stocker Cattle Stocking Rate Forage utilization is assumed at 70 per cent of available forage. Individual farm stocking … The proper stocking rate for a pasture is affected by its topography, accessibility and range site characteristics, as well as by animal diet preference and grazing behavior. A grazing area's stocking rate is different, but related to, its carrying capacity. This procedure is the essential link between planning stock numbers for the cattle enterprise and achieving the highest efficiency of green pasture utilisation. My paddocks range from 3-8 acres accordingly to the terrain and how I could access the water system. Cattle may overgraze the most productive sites and preferred species before they use less preferred sites and species. But is this always the case? Calculate proper stocking rate for cattle: Stocking Rate = Available forage Pounds eaten/month 5. Stocking rate decisions should be made before the ranch’s resources are jeopardized, and adjusted seasonally to balance forage demand with forage supply. The usual measure is dry sheep equivalents (DSE) per hectare (ha), however, this may also be expressed in terms of cattle per unit area, such as breeders (cattle) per ha or square kilometre. Denver, Colorado. To achieve maximum production and profit, livestock numbers must be matched to current and projected forage levels, not to an average carrying capacity. If a conservative stocking rate is chosen initially, the rancher may not have to reduce the number of grazing animals, but may underharvest the forage resource. My land can support my 100 cows for 2.65 months (utilizable lbs forage ÷ lbs of feed consumed per month) 272,000 ÷ 102,720 = 2.65 months . 1988.
