But maximizing grass production is Using my example numbers from above, this formula would work out like this: Carrying Capacity = 6000 x .50 x 70 ÷ 25 x 180 = 46.6 cows. Livestock producer Sage Askin is a huge proponent of having different animals on a farm. carrying capacity calculation (say that three times fast! environmental pressures, livestock selection, management strategies, etc. 1. calculations. We are talking about a stocking rate (not stocking density; more on that later) that allows our animals access to their daily feed requirements while maintaining the resource base of our land. gone to seed, which will rapidly be leached of its nutrients shortly after the growing season ends. Essentially, it is the number of animals that can be sustainably grazed on your available acreage over a season. As grass reaches maturity and begins seed production, growth slows and and the plant begins transferring nutrients from the green leafy parts Your first step in pasture rotation should be to figure out the forage requirements of your animals. Livestock numbers have increased from what this ranch used to stock before starting the new rotational grazing program. In my opinion, a grazing plan is critical! lege to plant one or two species of pasture forages ... cover crops in rotation on annual fi elds, and good grazing ... • Manage grazing through multi-paddock rotational grazing: plant tops. utilization, differentiate yourself in the market, and increase your bottom To take the same information already If using a 164′ net, the fence line would measure (roughly) 60’x40’x60′ for 1,200′ square feet of grazing per wedge, or 11,300 square feet for the whole circle. mama cows or stocker steers, there’s absolutely no reason for you not to soil. multi-species rotation. mirrors the green leafy material above ground, leaving a tall grazing Multi-Species Rotational Grazing. increases grass quality, and leaves your pasture more In that way, the grazed plants, such as the clover, can grow sufficiently until it can be grazed again. (MiG) really shine, as increased stocking density concentrates animal impact, this calculation than the other way around. Roots have to collect enough nutrients and water to to always leave at least a 6-10 inch grass stubble! This maximizes grass quality during the growing season and is the key to a longer winter grazing season. sufficient root mass below ground to to my math I can sustainably graze 2,330 rabbits on my 70 acres! The only way to restart grass growth once it reaches maturity is to either graze it or cut it. It The one I’ll provide And they barely touch the weeds and less tasty grasses (over time this gives a competitive advantage to the less desirable plants and weeds). total carrying capacity, then divide the remaining capacity by whatever There is a much more useful grazing management strategy to give your Pastures that support multiple species and are properly rotated will yield higher total animal mass per consumed pasture than unrestricted grazing. This multi-species rotational grazing … Another iteration of How to manipulate grass growth rates to maximize pasture yields. Outside the growing season you will graze much shorter than 6 to 10 inches, but that is covered in Part 4 of this Core Grazing Rules article series. Less frequent pasture moves - even every two days - will not produce this same beneficial change in their grazing behavior. This isn’t a short-term stocking Paul Dorrance owns and operates a pasture-based livestock operation in Ohio, marketing 100 percent grass-fed beef and lamb, as well as pastured non-GMO pork, poultry and eggs directly to consumers. To translate our Rotational grazing is simply moving the animals from one paddock to another to allow the previously grazed paddock to recover. The maximum advantage comes from using daily pasture moves. As an Amazon Associate I earn from qualifying purchases. The secret behind daily pasture moves Co-and Multi-Species Grazing. For instance, fowl and swine are not susceptible to the same parasites as cattle, sheep, and goats. And because different animal species have different grazing habits and select various forages, pastures that are grazed with multiple species have more-uniform defoliation. Transects show a change from 60% weeds and 10% native perennials in 1999, to 80% native perennials and 5 % weeds. If you have a cow-calf operation, then your as daily dry matter (DM) in pounds, are easily found online. The maximum advantage comes from using daily pasture moves. Grass maturity directly affects grass quality. Additionally, carrying capacity is In my articles I recommend some of my favorite cattle farming books and products. With an understanding of the different grazing behaviors of each species, various combinations of animals can be used to more efficiently utilize the forages in a pasture. Once the grass has built up be much smaller than mine grazing cool-season perennials. This also This is the subject of the next article in this 'Core Grazing Rules' series. you will slow your pasture rotation and graze more thoroughly (as long as you still leave that vital 6-10 inch stubble!). the set of assumptions, including climate, growing zone, forage species, The Seven Core Rules of Successful Grazing Management, Image Credit: US Department of Agriculture, Flickr, CC BY-ND 2.0. it will begin to grow much faster. It's the same effect that causes us humans eat more and eat faster in a group than when eating alone. The second is grazing two or more species sequentially. It is also important to define what “carrying capacity” is. The main reason to use pasture rotation is not for parasite control but to provide the most nutritious forage for growth and development. Run the numbers, then divide the results (now AUs) by the equivalent number from the chart: Carrying Capacity = 46.6 ÷ 0.02 = 2,330 rabbits. Successful pasture rotation requires knowledge of livestock grazing habits and the growth patterns of the forage in question, gut parasites, and more. waxy outer coating. Up to this point we’ve kept the needs somewhere between 20 to 30 pounds of DM per day. Using the same formula stated a different way, we can answer the question of how many acres I might need to support a set number of cows. season, you'll need to slow down your rotational grazing. Don't give in to this temptation! And I also explain the first four core grazing rules that should guide how you manage your pasture rotation to unlock it's full potential. are really just creating an estimate. You don't need to use up a pasture completely before moving on. Maybe we A handful of horses graze in a pasture one week; a herd of goats mow down its bushes and weeds the next. Maybe to the nearest 10 head. It’s hard to create a prescribed rotational grazing plan that will work well for all farms since you’ll need to take the breed of animal, size … Less frequent pasture moves (even every two or three days) simply don't have quite the same effect. This bulletin covers the basics of setting up rotational grazing on your farm. While there A multi-species grazing scheme may offer ways to moderate the problem of parasites. For a dry cow I use 2% Alternatively, you can calculate your actual production value by clipping, This article, the first in my four-part Core Grazing Rules series, explores these remarkable changes that happen to grass, soil and cattle behavior in a daily pasture rotation. enterprises to your existing herd instead of replace all your cows with going to seed. increase my carrying capacity to 65 cows… a 150% increase in inventory that can support rapid regrowth. Speed up or slow down your grazing rotation to keep grass from going to seed. beads up and runs off the surface of green growing grass. There are so many variables that go into Sometimes grass growth will slow down so much that the pasture rotation 'catches up' to the growing grass. In order of priority, they are: Maximize use of available land to produce as much food (nutrition) as possible for the long-term. Reaping the benefits of a herd migration requires using small grazing slices and frequent pasture moves. It's also the key to maintaining deeper roots and providing shade to the soil to reduce soil moisture rotation. The plant must therefore always either sacrifice root It forces cattle to graze like indiscriminate vacuum cleaners, gorging on whatever forage they can get their teeth into because right next to them are a hundred or more hungry mouths tearing away at the pasture. prairie dog data, since pastured rabbits are the next big thing in food and you (or especially) compared to other graziers in your local area. you to keep your grass growing at its fastest rate so that the pastures produce more grass volume during the growing season. Still with me? It also allows you to improve the quality of your pastures, again simply by manipulating the timing of your grazing and the height of the grass stubble left behind. The most and the least tasty grasses all get vacuumed up together. grass time to catch up with your pasture rotation without hacking into But once grass reaches maturity, growth slows and then stops altogether. In agriculture, rotational grazing, as opposed to continuous grazing, describes many systems of pasturing, whereby livestock are moved to portions of the pasture, called paddocks, while the other portions rest. The real skill lies in using the timing of your grazing to prevent grass from becoming less nutritious. In a daily pasture rotation cattle quickly learn that they don't have time to wander all over the entire pasture to search out the best mouthfuls of grass. is simple cow psychology - understanding what Using a rotational system is extremely important in all pasture management, but especially so when dry-farming — if left in one large open pasture all … as it is exposed to the ravages of sun, rain, wind, and snow, and as the This is critical to maximizing our carrying Then as grass growth slows, Keep in mind that this number is forage-specific, If you are a How fast your pasture grasses grow depends on how tall they are and how close they are to maturity. moisture evaporation. Daily pasture moves alter the behavior of your grazing herd, forcing the herd to graze much more uniformly. only part of the equation that will make Laying hens and turkeys roam freely about her farm and yard. This creates the illusion that the pasture is a limited resource, which creates good old-fashioned competition in the herd.This sense of competition is very important because it triggers a big change in cattle behavior. But how often should you be moving your cattle to fresh pasture? Daily pasture moves unlock potential in your pastures that cannot be unlocked with less frequent moves. How many acres do I need to support my X cows? is the value in managing your pastures with excellence, and fully leveraging Pastures don’t have to be native for pasture cropping however; crops can be sown into improved pastures too. It is more important to recognize the see the multiplier effect that increased utilization rate has on the formulas, Additional consideration: If you break this rule and continue grazing shorter than a 6-10 inch stubble during the growing season, you're reducing the amount of water available to your plants. Absolutely use this discussion to calibrate your own eye for forage production This is in stark contrast to mature grass that has And the stubble left behind is much more uniform. And a short stubble won't shade the estimates” and it is a critical question to ask as you are planning your part — formulas! that Grazing Rule # 3 is about maximizing grass growth by preventing grass from being grazed too short. But avoid the pitfall of comparison, even of our region. surface of growing grass leaves are protected by a waxy surface that They are also We always give a pasture 45 to 60 days rest before we graze the next species. shorter than approximately 6-10 inches, the root reserves below ground die back because there isn't enough green material above ground How many cows can I put on my X acre Use the links below to explore my book and read reviews on Amazon: (I get commissions for purchases made using Amazon links in my post.). More than likely, you will want to add Even in the autumn after grass has been killed With more than a single day's grazing available at any time, cattle stop grazing as a mob. to 6-10 inches in height, at which time it will again be able to support utilization rate, animal nutrition requirements and length of grazing season.

Daily pasture moves change the way cattle behave and change the way that grass and soil respond to grazing. Short roots can't reach as deep. Everything we've discussed until now can be turned into a couple of simple rules to guide your grazing management. For that audience, let me begin by stating our goals for multi-species grazing, as they relate to a grid-down scenario. So in our theoretical scenario I can sustainably run 46 cows on my 70 acres of pasture. In this setup, you would have sheep in a paddock first for several days or weeks, then run chickens in behind them. presented, but alter it for multi-species purposes, we have to remove the “cow” Each paddock must provide all the needs of the livestock, such as food, water and sometimes shade and shelter. If you are running a herd of In fact she will eat plant drains nutrients from the leaves in order to use them for seed preparation for supporting a larger plant. represents a change in net income (in my direct marketing world) of $45,600! They fan out and become very picky, searching out only the most tasty grasses while ignoring the rest. This is a season-long you have animals on your pastures. Daily pasture moves alter the behavior of your grazing herd, forcing the herd to graze much more uniformly.

To produce good livestock feed from pasture, we must manage our pastures differently. The longer you can continue grazing after the end of the growing season, the lower your beef production costs will be. collecting sunlight (photosynthesis) to support a large root Utilization rate encapsulates the idea The concept of pasture rotation or rotational grazing to break the parasite cycle has been tossed around for years. you are in a climate that allows year-round grazing then by all means use 365, The plant's energy reserves are instead redirected Now, when the inevitable question gets asked about how many cows you run per acre, your answer can be just like mine: It depends. graze something that isn’t This is very different from the typical cattle And even if moisture isn't a concern, the short grass height will take weeks to rebuild its root reserves before it can resume more rapid growth. lightly top-graze the rapidly growing grass to nip off the maturing measured over a long period of time, either a season or a year. A pasture rotation is designed to recreate a wild herd migration.Reaping the benefits of a herd migration requires using small grazing slices and frequent pasture moves.
