Differences in government policies and climate make Progressive Dairy â Canada useful to subscribers up north. In my area, I recommend having no fewer than 16 paddocks, as this is the minimum that I’ve found in my area for adequately managing the grazing concepts. Before increasing stock density above what is achieved from implementing a well-managed grazing program, ask yourself what you wish to achieve. Then, determine through trial what stock densities is best for your intended objective. These timely themes deliver information relevant to forage producers and other forage professionals to help them be more successful and profitable in their areas of operation. Decrease diet selectivity by forcing the consumption of plants that are less palatable or less preferred. The immediate conclusion of this calculation indicates that this ranch is slightly understocked; there is more feed available for grazing than there are cattle to consume it. Since forage demand is typically affected by an animalâs bodyweight, a common âbaseâ must be used to determine animal demand for forage. Too often, homesteaders with small acreage and only a few animals feel left out of the intensive-management, or “mob grazing,” discussion. Rotational Grazing Systems. To get a sense of what one AU is equal to, below are some equivalents to enable forage needs to be compared across different animals (Table 3). In this example, there is an excess of approximately 142.5 AUMs that will go unused during the year (961.5 AUM supply â 819 AUM demand). used rotational grazing, generally moving cows about every 36 hours. Plus, another information you will need is the daily … The AUM calculations for forage demand are: 100 cows x 1.2 AU x 6 months = 720 AUM 4 bulls x 1.5 AU x 6 months = 36 AUM 5 replacement heifers x 0.7 AU x 6 months = 63 AUM Total AUMs needed = 819 AUM. After having practiced rotational grazing or MIG for decades, I can assure you that the management is indeed intensive. Stocking rate is usually expressed in terms of total number of mature head, or head per acre (or acres per head). A functional cattle unit was upheld in the Archibald vs. Scone Council Land & The yield data provided by NRCS is for all forage produced during an entire year. Assume 100 1200-lb dairy cows eating 3 percent of their body weight grazing for 1/2 day on pasture with 2,000 lb of dry matter present per acre (Table 1) of which they consume 70 percent. With stocking densities between 100,000 to 500,000 lbs or more of body weight per acre, animals are usually moved several times per day. Progressive Cattle magazine captures the essence of the cattle producer and ranching experience. Progressive Dairy magazine combines current news and events, market reports and industry trends with dairy management and production articles, publishing information dairy producers can rely on to help serve their farmsâ needs. Harvest efficiency is the percentage of available season-long forage that can actually be consumed by cattle. The most effective application is where one uses a temporary electric fence intentionally constructed as required to address each unique situation and achieve the desired outcomes. Rotational grazing systems are generally the most efficient way to get the best use of pastures and maximum beef production per acre, as well as being healthier for the land and plants. It is assumed that a 1,000-pound cow consumes 2.6 percent of her bodyweight in feed daily (on a dry matter basis). Under these conditions, the 100 cows would graze down 1.3 acres in 12 hours or 2.6 acres in one day. Unfortunately, the most accurate method of determining annual forage yield is via the very time-consuming and labor-intensive process of hand clipping and weighing forages from pastures. The number of cows you can keep without damaging the soil varies from state to state, so you’ll need to do a calculation based on your number of animal units, length of grazing season, and stocking rate. Estimating carrying capacity: How many cows can I graze? University of Nebraska Extension Educator Terry Gompert says, “The objective is to create a major disturbance and then move on and give the pasture an extended period of rest — up to a year or more — before it is grazed again.” And what is the effect on the land? Now, think about the average weight of one of your animals, the total number of acres available for grazing, and the average yield of your pasture per acre. With experience, the tool of stock density becomes much easier to apply. ... on the animals you can graze per acre, and therefore on your wallet. ... Stock densities of 3 to 5 cows (or their equivalent) per acre … Calculating an operationâs carrying capacity should be done annually to account for predicted fluctuations in forage availability and to improve overall profitability. The main costs associated with transitioning rotational grazing are purchasing fencing, fencers, and water supply materials. If the property was managed such that each of the 50-acre pastures were subdivided into 10-acre paddocks for grazing, stock density in each paddock would be five cows per acre (50 cows divided by 10-acre paddock), or 6,000 pounds per acre (1,200 pounds per cow multiplied by five cows). Each issue of Progressive Forage contains articles which focus on a particular topic area within the forage industry. ), harvest efficiency, average cow weight, etc. If you have 500 acres and 50 cows, the stocking rate is 50 cows, or one cow per 10 acres. The magazine is published monthly with a sizeable portion of articles unique to Canadians. Recovery is dependent on the severity of disturbance and the intensity of grazing. Factors such as previous grazing management, forage species, age of stand, soil type, texture, fertility level and moisture conditions all impact forage yield and consequently … Stocking rate is usually expressed in terms of total number of mature head, or head per acre (or acres per head). Frequency and duration of grazing have to do with how often a pasture is grazed, how long a pasture is grazed and how long it is rested between g… It should be noted that some additional aspects of this operation were not accounted for in these calculations. Thus, it is crucial that operations properly balance forage supply with forage demand needed by their cow herd. As one can imagine, the grazing duration for the cow herd becomes shorter as the pasture or paddock size becomes smaller. The greater the stock density, the greater the impact upon a resource. Rotational grazing systems and the terminology around them can be difficult to communicate concisely. Variables such as season of application, management issue being addressed, long-term objective, type of soils and forages, terrain, herd size and weight, etc., also impact the application of stock density. Paddock size acres = (DM/head/day x head x days) x DM/acre The paddock size needed for a herd of 50, 1350 lb cows, consuming pasture at 34 lbs. We use Facebook Pixel and other cookies to optimize user experience. Often producers have called this rotational grazing and that is where HSD grazing begins. a breeding herd of 40 cows. These range from a large dairy farmer who rotationally grazes 1,600 head on his 2,100 acre all-grass farm to much smaller dairy, beef, sheep, hog, and even chicken operations. If harvest efficiency has been improved through the implementation of a properly managed grazing system, multiply total AUM by the guideline multiplier value found in Table … And the operation uses a simple rotation grazing system in order to have 30 percent harvest efficiency. “Up at Joel’s farm in his county they measure the grass in what’s called 'the average cow days per-acre.' In a sense, it provides the âguard railsâ for deciding on how many cows to run, impact of increasing harvest efficiency, the number of cows to increase or decrease due to high or low precipitation, etc. For instance, in grazing cattle, the distance to water and amount of slope present can both contribute significantly to harvest efficiency. Progressive Dairy - en français expands PDâs mission of providing useful dairy information by offering a publication specific to French-speaking dairy producers in Canada with a local touch. Example: The herd will graze each paddock for 3 days when 1000 pounds of pasture are available. Why use rotational grazing? Continuing on with our business of ranching series, we take a look at how we determine how many cows the ranch can support along with grazing … Download What Is High Stock Density Grazing? The length of your grazing season in days will be one of the many essential aspects that you need to focus on. This equals 750,000 pounds of forage that is available per year on the operation. How many cows per acre will fit on my land? However, it is crucial to realize several things, including the fact that all calculations are based on estimates including forage yield (which is based on soil survey data, precipitation, etc. 500 cows — or more — per acre. What is Intensive Grazing? “Even though I no longer own the cattle, I think rotational grazing under irrigation is still more profitable than corn right now, considering cattle prices,” he says. In reality, this calculation does not allow carrying capacity to be fine-tuned to a very specific number of animals. Influence more uniform grazing utilization of pastures by strategic fencing, forcing utilization of areas that are avoided or grazed disproportionate to production. Rotational grazing (RG) has been promoted by many land-grant universities and USDA-NRCS (Natural Resources Conservation Service) for a number of years. Substantial research has shown rotational grazing to have many benefits, including improvements to soil fertility and health, reductions in hay feeding, increased stockin… It will make your pasture last longer and reduce the incidence of internal parasites in the goats. This equals 750,000 pounds of forage that is available per year on the … A few simple steps can be taken to determine carrying capacity and to compare forage supply with demand. Rotational grazing involves the frequent movement of groups of stock through a series of paddocks and allows small landholders to decide when and for how long a pasture will be grazed and … In the January 2016 News and Views, there is an article titled âPotential Mob Graziers Should Consider Precautions.â The focus is on ultra-high stock density (UHSD) grazing, which is the management tool of using grazing livestock in much higher than normal concentrations to achieve landscape-focused objectives with the long-term goal of enhancing soils, forages and livestock production. It is usually expressed in pounds of live-weight per acre at a given moment in time. ... Kelsie is from southwest Missouri … The trade expectations... Progressive Cattle provides practical beef operation management articles, timely news, cutting-edge technology information and thought-provoking opinions to you at no cost. If you have 500 acres and 50 cows, the stocking rate is 50 cows, or one cow per 10 acres. Cattle have to be moved (rotated) to a fresh paddock more often, depending on the amount of grazing forage that is available and the amount of forage residual desired to remain after the grazing event. It is the intentional application of grazing livestock in higher than normal concentrations to achieve landscape-focused objectives. There is a simple calculation to help you work out how much land you need for your cows. It looks like our rule-of-thumb held up pretty good, 11 cows on 20 acres, is 1.8 acres per In drier areas you may need up to 100 paddocks. emailProtector.addCloakedMailto("ep_9a036c8e", 1); Jason K. AholaemailProtector.addCloakedMailto("ep_fc6c56fe", 1); Associate Professor Beef Management Systems Colorado State University. The Pasture Project provides very useful guidelines around terminology of various Grazing Systems such as how many cows per acre … In a simple grazing rotation, stock density increases while stocking rate remains the same. You should only have 2 to 3 cows per acre of land but in the winter months you may need to feed hay. Historical knowledge of an operation can help to determine likely forage yield per acre, including past stocking rates, but it can be inaccurate at times. General guidelines as to the expected observed results of the properly managed application of HSD grazing at increasing stock densities as it relates to the variables of selective grazing, grazing distribution and animal impact.
