A few weeks later, dry ewes can be grazed on the same grass that has had the best forage removed by the growing lambs. A grass leaf that is two inches long has a much larger area for photosynthesis and can grow much faster, recover from grazing much faster and produce much more forage over the course of the season. Late winter/early spring grazing. Our sheep eat the annual rye grass seed heads as well as the grass blades. Increased resistance to drought. 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. Certain paddocks/pastures can be seeded or developed for seasonal grazing. Let Premier help decide which fence is best for you. In the spring, California rangeland is carpeted with wildflowers and dotted with grazing cattle. Plants given time to recover and put down roots, which increases organic matter. Rotational grazing allows plants to remain healthy by renewing energy reserves, rebuilding plant vigor, and giving long-term maximum production. 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. 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. The manager has to consider the expenses of rotational grazing into consideration, including more fencing costs, more labor, and usually a more expensive water system. 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). Newly weaned lambs could be put on the best forage. On the other hand, if you pen the sheep up right at the end of winter, in two weeks you can quit feeding hay.

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. Control less desirable plants. 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. 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. . Soil compaction. With continuous grazing and over a few years the favorite species die out and the less tasty species increase. Image Credit: akial, Flickr, CC BY-SA 2.0. Moving the sheep every day or even every week to a new pasture allows the shepherd to assess animal health. Concentrates manure in the pasture and not by the water tank. By grazing smaller paddocks for shorter periods of time, horses do not have a chance to regraze new growth of their preferred forages, which both weakens the plant and contributes to the formation of … A chemical used for killing insects. A grass or clover plant that is nibbled on every few days loses, has little time to recover from the injury insult of grazing before being injured (grazed) again. Sheep and cattle that are regularly rotated to new pastures every few days in low stress procedures are much easier to manage. 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.

A grass manager can use a group of sheep to slightly overgraze an area to expose a little soil and cut down on the grass cover. Do the math: a month of feeding a little less hay (let’s say 80% of peak winter hay) or two weeks of feeding slightly more hay (100% of peak winter hay levels) while they are in the pen. By contrast, in a continuous grazing system the sheep would likely have moved to the sheltered part of the pasture on their own. Decreased water run off and increased soil organic matter keep pastures more resistant to impacts of drought, increase forage production and maintain forage growth longer into periods of droughts. In this way, the animal has a comfortable place which is cheap and easy to maintain. A monthly publication. A unit for measuring length in the metric system.

For this, you require only one drinker which you place in the corner of the field. Rotational grazing allows plants to remain healthy by renewing energy reserves, rebuilding plant vigor, and giving long-term maximum production. There are many benefits to this strategy as rotational grazing allows producers to utilize their pastures more efficiently by decreasing feed costs, decreasing weed pressure present in a pasture setting, improving the health and performance of grazing … Removing sheep from rye grass pastures in late spring/early summer will allow them to go to seed.

The ability to limit graze the classes of sheep that don’t need unlimited access to forage and would eat more than they need, greatly decreases the amount of hay we feed and purchase. Grassland soils are a great reservoir for organic carbon. In rotational grazing, pasture size and shape . Dry ewes will eat much more forage than they need to maintain body condition or to get back into breeding condition. Increased soil organic matter and better forage cover due to better grazing management will slow water movement during hard rains and increase absorption of water by the soil.

There are many approaches and types of grazing that fall under the broad umbrella of rotational grazing. This results in poor grazing efficiency because only part of the vegetation is utilized at its optimum rate. Looking at the overall pasture composition becomes an important step to determining if any improvement is necessary. In summary, controlled rotational grazing has many advantageous. Certain annual plants that reseed usually need a few weeks to develop a seed head and then time for seeds to scatter without grazing animals present. The top 5 reasons to rotationally graze: It loses root mass and energy reserves and has greatly reduced forage production over the grazing season. Using this method cattle are concentrated on a smaller area of the pasture for a few days then moved to another section of pasture. (Also referred to as Prescribed Grazing Management or Management Intensive Grazing) The goal of rotational grazing management is to allow plants to continually produce large volumes of high quality leaf material by setting (1) frequency, (2) intensity and timing, and (3) duration of grazing..

The recurring periods of grazing and resting for regrowth continue throughout the time grazing is allowed. Our pastures have a couple areas of cheat grass which has a short window of decent grazing followed by many months of being dry and unpalatable with sharp pointed seeds. Manure nutrients are more evenly distributed across the field as well. Graze.

It also requires very little expense in fencing materials other than the exterior fence. Rotational grazing. Keep up on all of the latest news and industry trends. Two key advantages in our farm’s system are the 30-70% increase in forage production and the ability to control and limit feed dry ewes and early gestation ewes. By only providing a few days or a single day’s worth of forage, there are many fewer opportunities to walk on plants and excrete on forage making it less palatable. The growth rate of the plants are not considered nor the recovery time of plants after grazing. lactating ewes versus dry ewes). We also appreciate that the sheep handle much easier, reducing stress on the people and the flock. 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. A shepherd has to determine whether it works for their system. A grass leaf that is half an inch long has a very small “solar panel”. 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.

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. Once forage in a paddock is depleted, stock will naturally gravitate to the next paddock once it’s opened. The general rule of thumb is that a well managed controlled grazing program can increase quality forage production by 30-70% each year. Each paddock must provide all the needs of the livestock, such as food, water and sometimes shade and shelter. Continuous grazing (the alternative to rotational grazing) tends to result in the best forage plants being weakened by regular grazing, while the least desirable plants thrive. Grazing Divisions/Paddocks and Rotational Grazing Why use this system? It is important to note, even small size pastures can be divided into smaller cells for effectively managed grazing system.
