Rotational grazing is a management strategy used to maximize forage growth and encourage desirable plants and plant parts! [9] The use of multiple species in the pasture helps to minimize weeds. Although shade provides relief from heat and reduces the risk of heat stress, animals tend to congregate in these areas which leads to nutrient loading, uneven grazing, and potential soil erosion. [2], Herd health benefits arise from animals having access to both space and fresh air. Generally, the leaves of plants are much more palatable, nutritious, and photosynthetically active than stems. Rotational grazing is nothing new. 4.ço-ýjVà¾^&³ê´Ø 2003. Additionally, a transition to rotational grazing is associated with low start-up and maintenance costs. The McBride Fencing Rotational Grazing Solution This product has truly helped our farm by managing grazing and maintaining high quality and quaintly pasture for our livestock, as we know it will yours. In rotational grazing livestock are moved to portions of the pasture, called paddocks, while the other portions rest. Mechanical controls such as repeated mowing, clipping, and hand weeding can also be used to effectively manage weed infestations by weakening the plant. Rotational grazing is immediately different from continuous grazing because you’re confining cows to a smaller areas, but moving them when the quality of herbage demands it. A well managed rotational grazing system has low pasture weed establishment because the majority of niches are already filled with established forage species, making it harder for weeds to compete and become established. Resting grazed lands allows the vegetation to regrow. Rotational grazing is the practice of moving grazing livestock between pastures (often called paddocks) as needed or on a regular basis. “With the rotational grazing system, our grass had a chance to rest and it responded so much better compared with neighboring fields that were grazed during that long season.” He grabs another handful of grass. [14][15][16] If a pasture was continuously grazed in the past, likely capital has already been invested in fencing and a fencer system. Established forage plants in rotational grazing pasture systems are healthy and unstressed due to the "rest" period, enhancing the competitive advantage of the forage. It is important to recognize that no single approach to weed management will result in weed free pastures; therefore, various cultural, mechanical, and chemical control methods can be combined in an weed management plan. [13] Cost savings to graziers can also be recognized when one considers that many of the costs associated with livestock operations are transmitted to the grazers. Distribution of grazing is likely to become more uniform when cross-fencing reduces diversity of range s… The first step to rotational … Continuous grazing. The net effect is more productivity per acre at less cost. In addition, these pasture system are less susceptible to erosion because the land base has continuous ground cover throughout the year. Dividing up a pasture into paddocks to prevent overgrazing goes back to the earliest agrarian societies. A TechnoGrazing system on Burleigh, New Zealand. Depending on the management model, plant production has been shown to be equal or greater in continuous compared to rotational grazing in 87% of the experiments. The nutrient content in these manure sources should be adequate to meet plant requirements, making commercial fertilization unnecessary. Sullivan, K., DeClue, R., Emmick, D. 2000. Another consideration is that while production per cow is less, the number of cows per acre on the pasture can i… Rotational (Paddock) Grazing. A continuous grazing system is one where horses are houses on a single pasture for an extended period of time. [2] Cultural controls include: avoiding spreading manure contaminated with weed seeds, cleaning equipment after working in weed infested areas, and managing weed problems in fencerows and other areas near pastures. Rotational grazing is a specialized grazing system that was introduced in the mid-20th century as an important tool to adaptively manage rangelands ecosystems to sustain productivity and improve animal management (Teague et al., 2013). There is significant scope for more farms to exploit its benefits. From: Advances in … Rotational grazing is a system where a large pasture is divided into smaller paddocks allowing livestock to be moved from one paddock to the other easily. The size and number of small pasture cells can vary based on available acreage, the number of animals, the productivity of the pasture, and ho… The longer a pasture rests, … Rest-Rotation Grazing The rest-rotation grazing system was designed by Gus Hormay of the U.S. Forest Service and was first implemented in the 1950s and 1960s. Ramps to Surface Water: [2] Rotational grazing systems are often associated with increased soil fertility which arises because manure is a rich source of organic matter that increases the health of soil. It is therefore important to ensure that the herd is eating enough at the end of a rotation when forage will be more scarce, limiting the potential for animals to gorge themselves when turned out onto new paddocks. High Intensity, Low Frequency Grazing System [9], Ruminal tympany, also known as bloat, is a common serious problem when grazing ruminants on fresh, young pasture, and if left untreated can be fatal. [11] Legumes are able to fix atmospheric nitrogen, thus providing nitrogen for themselves and surrounding plants. With this grazing strategy, stock are allowed to graze one pasture cell at a time. The total grazing capacity of both pastures is combined into one herd, so that the herd is rotated between the two pastures. ïfèç^jº

Small-Scale Rotational Grazing Keeping your cattle, goats, sheep, or chickens moving is the key to successful, controlled rotational grazing on a small homestead. Special care must be taken to ensure that high use areas do not become areas where mud, parasites or diseases are spread or communicated. The animals experience less disease and fewer foot ailments, depending on the rotational system being used. Once the undesired species in a pasture system are identified, an integrated approach of management can be implemented to control weed populations. Although milk yields are often lower in rotational systems, net farm income per cow is often greater as compared to confinement operations. Once forage has recovered, horses can be returned to that pasture to graze. 2. “Rotational grazing is the practice of moving grazing livestock between pastures (often called paddocks) as needed or on a regular basis. [18], System of grazing moving animals between paddocks around the year. However, the system is superior to year-long grazing. [7], A key element of this style of animal husbandry is that either each grazed area must contain all elements needed for the animals (water source, for instance) or the feed or water source must be moved each time the animals are moved. Regardless of animal type, plant variety or the area’s climate, the diversity of vegetation decreases in any area that’s continuously grazed. endstream

[2] The intent is to allow the pasture plants and soil time to recover. It is easily adapted to a three- or four-pasture, single-herd, low intensity, rotational grazing system in which cattle are moved to the next best pasture available. Although milk yields are often lower in rotational systems, net farm income per cow is often greater as compared to confinement operations. Learn about the different methods for getting water to cattle in a rotational grazing system. For example, the grazers actively harvest their own sources of food for the portion of the year where grazing is possible. The previously grazed cell is then allowed to recover; it generally takes about 20-30 days for the forage to regrow to 6-8 inches in height. When forage has been grazed down, animals can be rotated into the next cell. Learn how to get water to cattle in rotational grazing systems. Intensive rotational grazing implies many paddocks are utilized and livestock are moved on a frequent basis. A key step in managing weeds in any pasture system is identification. Watering systems for grazing livestock. Rotational grazing builds links between the health of soils, plants, and animals. Two common types of grazing systems used in horse farms are continuous and rotational. Many pastures undergoing certain types of rotational grazing are less susceptible to soil erosion. Although grazers remove nutrient sources from the pasture system when they feed on forage sources, the majority of the nutrients consumed by the herd are returned to the pasture system through manure. The rotational system provides an opportunity to move livestock based on forage growth, promote better pasture forage utilization, and extend the grazing season. [6] Rotational grazing is especially effective because grazers do better on the more tender younger plant stems. The main costs associated with transitioning rotational grazing are purchasing fencing, fencers, and water supply materials. These grazing regimes are sometimes said to be more resilient and more capable of responding to changing environmental conditions. Block grazing is a rotational grazing system in … Additionally, the system is less prone to excess nutrient fertilization, so the majority of nutrients put into the system by manure sources are utilized for plant growth. [2][13], Managers have found that rotational grazing systems can work for diverse management purposes, but scientific experiments have demonstrated that some rotational grazing systems do not always necessarily work for specific ecological purposes. Use of herbicides may restrict the use of a pasture for some length of time, depending on the type and amount of the chemical used. These plant species will not be grazed by the herd and can be recognized for their prevalence in pasture systems. [2] However, certain species such as thistles and various other weeds, are indigestible or poisonous to grazers. The risk of bloat can be mitigated by careful management of rotations, seeding the non-bloating European legume species Lotus corniculatus in pasturelands, reducing the amount of legumes/increasing grasses, providing sufficient supplemental feeding and extra fodder when turning out on new paddocks, reducing the size of the paddock when livestock is first turned out, and daily rations of the anti-foaming agent poloxalene mixed well into the fodder.[2]. kÌÈ:Oîè8g)c{Yàí b0Î3Ρ1Ò®ó3ß½@õµÿ. Berntsen, J., Grant, R., Olesen, J.E., Kristensen, I.S., Vinther, F.P, Molgaard, J.P., and Petersen, B.M. [3][4][5], Rotational grazing can be used with ruminants such as beef or dairy cattle, sheep or goats, or even pigs. Rotational grazing can utilize two or more paddocks. Appendix E. Water Systems Design Considerations A. This is due to the additional costs associated with herd health and purchased feeds are greatly reduced in management intensive rotational grazing systems. Blanchet, K., Moechnig, H., and DeJong-Hughes, J. 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. Additionally, a transition to rotational grazing is associated with low start-up and maintenance costs. [12] These systems are fertilized with on-farm sources, and are less prone to leaching as compared to commercial fertilizers. There are many approaches and types of grazing that fall under the broad umbrella of rotational grazing.
