Having this number allows you to rotate animals to a new paddock each week with a four-week recovery. Create an open forum for industry discussion and an easy-to-read magazine of expert information about the forage industry. The grazing tolerance trait provides a safety net or insurance against stand damage from overgrazing. Number of paddocksDividing the alfalfa field into smaller paddocks is necessary for rotational grazing. Requirements for grazing alfalfa Establishing the standRequirements for establishing an alfalfa stand for grazing are the same as for hay. Continually grazing a pasture with too many animals will lead to reduced forage availability and quality and animal growth. Any variety for grazing should meet the same requirements for yield and disease resistance that would be expected in a hay variety. ⢠Observe cattle closely when turning in for the first time. Additional fencingAlfalfa must be grazed on a rotational basis. Rotational grazing is the practice of moving grazing livestock between pastures (often called paddocks) as needed or on a regular basis. The problem with rotational grazing is “moving livestock between paddocks every set number of days.” Pasture does not respond to grazing the same way throughout the growing season. All editorial content for Progressive Forage is driven by one primary goal â to provide informational resources that ensure success for forage producers. During peak growth, you may need to cut one or more paddocks for hay or silage to maintain high-quality grazing in the rotation. Also provide a sacrifice paddock for times when the ground is too soft to support hoof traffic. Maintaining the standStands of alfalfa are best maintained under grazing when stresses from insects, diseases and weeds are minimized. Increased area per animal is required as the season advances into the hot summer months, when pasture regrowth slows down. ⢠Do not graze alfalfa for three days following a killing frost (below 24°F). There are many approaches and types of grazing that fall under the broad umbrella of rotational grazing. The use of temporary fence is an inexpensive way to divide fields into the smaller paddocks and can be moved based upon the producers’ preference. Disadvantages of set stocked continuous grazing are that pasture utilisation may be above or below the optimal level at any one time. In times of slow growth, you may need to further divide one or more paddocks to permit longer recovery periods. Overgrazing has been causing huge and incalculable resource losses. Rotational grazing allows a producer a better opportunity to use livestock to manage grasses, legumes, and weeds. The first delineation needed in discussing the different types of grazing methods is to understand continuous and rotational grazing. Garry Lacefield, Jimmy Henning, Roy Burris, Charles Dougherty and Curtis Absher, Grazing alfalfa: Advantages and disadvantages, The irony and the ecstasy of alfalfa in the South, Save on nitrogen for small-grain forages after alfalfa. There is also the potential for overgrazing with livestock habitually revisiting preferred areas. Consider the number of paddocks, stocking rate, grazing time, recovery period, ease of cattle movement, water, salt and minerals. Copyright © 2021. Stand declineIf alfalfa plants are not grazed properly, weeds increase and stands decline. Begin with a minimum of five individual paddocks. Exceptions include the first grazing in spring and when alfalfa is dormant (during drought and after freezedown). Grazing animals may damage alfalfa crowns during wet and muddy conditions. Under good conditions with rapid growth, the rest period will be three to four weeks or less. This method is most effective where forage availability is plentiful and the manager does not wish to increase livestock numbers. Although pure stands can be grazed successfully, alfalfa/grass mixtures have advantages in grazing situations. Specifically, in a management-intensive grazing system or intensive grazing system, the calves are allowed to creep graze in the pasture ahead of the cows in the rotation (if adjacent) or are allowed access to adjacent areas planted or managed specifically for … Doing so requires that fields be subdivided so cattle are restricted to one area for a time, then moved to another area. * Lactation period was 280 days. Pros and Cons of Grazing Pros and Cons of Grazing . A simple pre-harvest marketing plan, part 1, Biden administration should look to producers for viable solutions, Silage trials provide insight into top hybrids, A 'normal' day at the Nebraska Unicameral, MSU AgBioResearch enhances mission of Escanaba center, temporary fence is an inexpensive way to divide fields into the smaller paddocks, Allowed HTML tags: . While grazing returns significant amounts of plant nutrients to the soil, it is important to continue soil testing to determine fertility needs. According to Payne (1985) rotational grazing is strongly advocated in the Philippines. Electric netting allows our shepherds to quickly subdivide pastures. Extended use of standGrazing can extend the useful life of a stand by a year or more for old alfalfa hay fields where some of the stand has been lost or has become weedy. They can provide an economical source of livestock feed, reduce labor requirements, build soil tilth and fertility, reduce erosion, and reduce invasions of noxious and poisonous weeds. To accomplish this, rotate animals more frequently or reduce stocking rates. However, alfalfa plants can be grazed during this period if they are not grazed short. ⢠Do not turn hungry cattle into an alfalfa field, especially when plants are wet from dew. The biggest gains in pasture growth are usually achieved through improved fertility and/or introduced sown species, rather than grazing method. Farm Progress is part of the Informa Markets Division of Informa PLC. Continuous grazing requires less input and labor. Another limitation of this system is during slow-forage-growth periods animal numbers need to be adjusted, or more acreage available for grazing. 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. ⢠Do not graze immature alfalfa or alfalfa/grass. More management decisions. All rights reserved. Assist forage producers in improving profitability and efficiency. Introduction to Pasture-Based Dairy Models http://extension.missouri.edu/p/G3050 Rotational grazing is simply taking one large pasture and breaking it up into two or more smaller pastures. The type of grazing system that is best suited for a given farm will depend on the goal of the producer and their resources. In addition, damage to new crown shoots can occur when cattle are left on an individual paddock after new shoots develop. On good, productive stands, stocking rates of 1,500 to 3,000 pounds of animal live weight per acre are generally suggested. Considerable flexibility exists in the grazing time, but plants should not be grazed for more than a week. The use of temporary fence is an inexpensive way to divide fields into the smaller paddocks and can be moved based upon the producers’ preference. Continuous grazing is more successful when implemented with dry cows, bred heifers, and beef cows of moderate to low milking ability. If you see an improvement, divide it again the next year, or try dividing another pasture in half. You need enough paddocks to permit proper grazing management, but few enough to meet individual management resources. Progressive Cattle magazine captures the essence of the cattle producer and ranching experience. 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. There is an increased risk of poaching in this system due to the traffic that builds up beside the drinker. 6 Types of rotational grazing. animal production ha-1 = production head-1 × no. Using temporary fence materials and portable watering tanks allows a producer to experiment with different paddock sizes and watering systems. Rotational grazing is a practice that, if done correctly, can help increase your pasture productivity. Recommendations for grazing alfalfa that have been used for many years approximate hay harvest (i.e., graze rotationally, provide for a rest or recovery period, then graze again). The cell is then allowed some time to restore and rest until the forage is 6 to 8 inches in growth, and the equine is moved to the other cell for grazing till then. The simplest is moving livestock between paddocks every … Disadvantages of grazing alfalfaThe most frequent concern of producers considering grazing alfalfa is bloat, but it can be minimized with precautions. To learn more about managed grazing, and how it is effective, join us at one of our upcoming events. Differences in government policies and climate make Progressive Dairy â Canada useful to subscribers up north. Rotationally grazing your pasture should also allow appropriate rest periods. Any rotational schedule beyond one week does not qualify as rotational grazing. Continuous grazing can serve a role in livestock production where animals are encouraged to only eat the "cream of the crop" such as might Lower fertilizer expenseUnder grazing, over 80 percent of the plant nutrients ingested are returned as dung and urine. With proper grazing management, alfalfaâs high yield potential can be converted to high levels of animal production per acre. These studies show that total seasonal yield is not reduced by any graze-hay systems. This movement allows the grazed paddock a rest period that permits forages to initiate regrowth, renew carbohydrate stores, and improve yield and persistency. In addition to advances in development of grazing-tolerant varieties, progress is also being made in breeding varieties with reduced bloat potential.
