To eat grass growing in a field. Advantages of Rotational Grazing By Jim Morgan, PhD Rotational grazing is the practice of moving grazing livestock between pastures (often called paddocks) as needed or on a regular basis. They associate the humans with better food. Concentrates manure in the pasture and not by the water tank. Lagging animals are noticed when they all surge past the gate where the shepherd is standing. Putting a mob of sheep into a smaller paddock for a day or two, with a limited amount of forage, encourages the sheep to graze both the plants they love as well as the ones they do not like as well. With controlled grazing, paddocks can be developed for seasonal grazing, whereas this is much harder with a single larger pasture. Control less desirable plants. Two specific things include: Increased organic matter and soil fertility will reduce needs for purchased fertilizers, and result in increased forage production. Many graziers use temporary electric fence systems to manage the size of the paddock. Irrespective of the grazing option selected (paddock, strip grazing or block grazing), there are a number of recommendations common to all systems, as listed below. My ewes don’t listen to me when I tell them this pasture has to last you two weeks. A rotational grazing system should have a minimum of five to six divisions and ideally have seven to eight divisions per grazing group on the farm. Select the animal below that the fence will be used to keep in or out. A monthly publication. The simplest is moving livestock between paddocks every set number of days: But well-managed rotational grazing means that you evaluate the nutritional and forage needs of your animals, assess forage quality and quantity, regulate the acreage of access and control which parts of the pasture/range that the animals have access to. Rotational grazing is the practice of moving grazing livestock between pastures (often called paddocks) as needed or on a regular basis. Under rest rotation, one or two pastures are rested the entire year while the remaining pastures are grazed seasonally, depending on the number of pastures and herds. Controlling paddock size will decrease the amount of hay you buy or allow you to reserve more forage for the weaned lambs that are growing to market size and need much more nutrition. There are many approaches and types of grazing that fall under the broad umbrella of rotational grazing. MiG was coined by Jim Gerrish, a well-respected grazing consultant for livestock. Open a gate and call is often all that you need to do to get the sheep or cattle to follow you to the next pasture or to the working corrals. While less of an issue with sheep than cattle (150 lb ewe versus 1000 lb cow), walking longer distances over the same paths increases soil compaction, which decreases soil fertility, water absorption and ability of forage plant roots to penetrate the soil. Often times rotations are set. 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. Then, you divide the field from there into triangle sections of equal area. Be sure to have fence set up ahead of time so you’re not keeping your stock waiting for fresh forage. Some plants tolerate freezing and other plants have little grazing value after frosts in the fall. Some staff can provide good small ruminant advice, or if not, get them to talk beef cattle — you can then make the small conversions needed to make the beef advice work for sheep. Rangelands are those lands on which the native vegetation (climax or natural potential plant community) is predominantly grasses, grass-like plants, forbs, or shrubs suitable for grazing or browsing use. Of course, certain animals such as late gestation ewes or newly weaned lambs probably will need that extra forage and cannot be limit fed. In the spring, California rangeland is carpeted with wildflowers and dotted with grazing cattle. Generally, the main advantages of the zero-grazing system are: ... A soft bedding provides comfort to a cow and prevents wounds on its skin. Winter should not put an end to your intensive grazing rotation. Monterey County rancher George Work says the beauty of this ever-changing landscape is one of his greatest pleasures because he knows cattle grazing, and other good range management practices, can add greatly to the health and vitality of this imp… Spreading manure around the whole pasture since grazing sheep and cattle typically return to the water tanks or a single favorite shade tree. Rotational grazing also has the potential to reduce machinery cost, fuel, supplemental feeding and the amount of forage wasted. In many years, we are able to put the sheep on the cheat grass areas in early spring and graze them hard. Now is the time to start assessing the overall conditions to decide what management steps must be taken to have a productive pasture for the coming year. We also appreciate that the sheep handle much easier, reducing stress on the people and the flock. Certain paddocks/pastures can be seeded or developed for seasonal grazing. Simply put, rotational grazing is any grazing regime that involves the rotation of grazing animals through 2 or more pastures, which are then allowed to rest for any given period. The main benefits of rotational grazing stem from a focus on plant growth phase. They will eat it all in few days, even at times of the year when they don’t need as much nutrition. Let Premier help decide which fence is best for you. Saving the best forage for the class of sheep that needs it the most. Plants that are over-grazed or less healthy from being grazed every few days have smaller root mass which leads to less soil organic matter. Quality and animal performance can be high since animals are only eating high-quality plant tops. Animal assessment. In continuous grazing, pasture size and shape . Rotational, or deferred grazing, involves moving animals through a series of three or more pastures, in an effort to match the forage availability to the animals' production needs. Select The Best Fence Design For Your Site. Sheep and cattle that are regularly rotated to new pastures every few days in low stress procedures are much easier to manage. Once forage in a paddock is depleted, stock will naturally gravitate to the next paddock once it’s opened. Then more of the broadcast seeds fall on bare soil and are more likely to germinate. Premier’s goats grazing alongside ElectroStop® 10/42/12. The more control a manager has over paddock size, the more he/she can put dry ewes on poorer quality forage and save the best forage for the growing lambs or the lactating ewes. Home » Sheep Guide » Advantages of Rotational Grazing. Jim Gerrish. With adequate fencing and the ability to manipulate size of paddock with portable electric fencing, a shepherd can postpone buying hay for a few days or weeks and save funds. Dividing a pasture into smaller cells and rotating the use of each cell is referred to as Rotational Grazing. Increased soil fertility. Removing sheep from rye grass pastures in late spring/early summer will allow them to go to seed. A plant that is able to recover from a single grazing incident for three weeks or more before being injured by grazing again has more resources to put into growth and can produce 30-70% more forage. Rotational grazing. This results in poor grazing efficiency because only part of the vegetation is utilized at its optimum rate. Increased resistance to drought. This grazing approach is termed “leader – follower”. 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. A well managed grazing program on average should allow 30-70% more stock on the same acreage or a significant reduction in purchased hay for winter feeding or droughts. A 2 inch blade of grass can grow an extra two inches of blade length in one-half to one fourth of the time it takes a 1/2 inch blade of grass to grow 2 extra inches when there is enough moisture and sunlight. On the other hand, if you pen the sheep up right at the end of winter, in two weeks you can quit feeding hay. Rotational grazing supports more diverse bird communities, more amphibians and were just as good as grassy buffers in regards to bank stability and in-stream habitat. Learn More ». All year for perennials to have long-term impact on pasture composition. A flock of ewes or herd of cattle that are given access to 20 times as much forage as they can eat in a day or two will walk a lot of forage into the ground, defecate and spoil forage as they walk to and from the best forage spots over the 3 weeks or more that they are on the pasture time. If your sheep have access to whole pasture all winter, every time there is a little green, they will bite off that leaf. The rule of thumb for most plants is to not graze below a minimum of two inches (though this can vary, as bermuda grass can be grazed much lower to the ground than orchard grass or big bluestem). Rotational grazing allows for better manure distribution that acts as a source of nutrients to the soil. Looking at the overall pasture composition becomes an important step to determining if any improvement is necessary. Only one portion of pasture is grazed at a time while the remainder of the pasture “rests.” Rotational grazing allows plants to remain healthy by renewing energy reserves, rebuilding plant vigor, and giving long-term maximum production. Management-intensive Grazing: The Grassroots of Grass Farming. Grazing Divisions/Paddocks and Rotational Grazing Why use this system? Green Park Press. If the sheep are kept on the area with the broadcast for a day or two, their hooves can be used to help press the seed into contact with the soil. Limit feeding during times of drought. The ability to control paddock size can strongly encourage your sheep (or cattle) to eat the less desirable plants at the times you need them to. Keep stands of favorite forage species.
