Note: These calculations use the figure of 3% of bodyweight as a demand calculation. So if you had six paddocks and each paddock size was 2.25ha (5.6 acres), the total available cover per paddock would be (1,500gm DM/ha x 2.25) 3,375kg DM. Grass should ideally be measured weekly or more in peak growth, but the key is to measure each paddock at least once between grazings so that there is always a record of how that paddock/field compares to others. And it can work with various different numbers of paddocks: Four days is the maximum grazing duration wanted because of the all-important rest period in between grazing. In cover terms, this should be around 1,500 DM/ha, which is 4cm in height and roughly the height of a golf ball. Combined demand = 720 + 120 = 840kg DM/day, This is the opening cover minus the target residual cover. Temporary electric divisions work best in large paddocks that double up for harvesting silage. Those with fewer opportunities to gain more land, or using seasonal lets, can expand flock or herd size through better grassland utilisation – rotationally grazed grass is better utilised grass. The rotation length is the number of days it would take for the mob of cattle to go through all their allocated paddocks. High-Frequency Rotational Grazing. 6. Learn how to calculate paddock size based on dry matter intake goals from grazing expert and organic certification consultant Sarah Flack. Rotational grazing (also known as management-intensive grazing, MIG) differs from continuous grazing in that land is separated into smaller paddocks and the group of animals is moved regularly between paddocks. Hi, Jenna. ft. – 20 cf This might mean you need to supplement them for a short time, while holding them back from entering the grass system, while grass ‘cover’ builds. Demand will vary through a season as cows progress through gestation and calves mature. Taking them off of land frequently reduces medical issues like parasites. This number can vary depending on geographical area and farm type – on farms where grass growth is very strong, or in peak growth season, this may need to be shorter. The difficult thing in the first year is that you won’t have shut up fields or paddocks in a set order as would happen in a rotational grazing system. rotational grazing for parasite control only works if they don't go back to the barn, either, for 30+ days. When she's not helping farmers, ranchers and land managers on-site, she writes articles, and books, and edits videos to help others turn their livestock into landscape managers. “Ultimately all you are trying to do is match your stocking rate to your grass growth,” says Gareth Davies of Gareth’s Grassland Advisory Service. Kathy worked with the Bureau of Land Management for 12 years before founding Livestock for Landscapes in 2004. There are no really hard-and-fast rules, but some generalization is possible. Paddocks five and six can then be grazed with other stock on the farm, such as sheep or store cattle, or cut for silage. Set stocking Rotational grazing A grass cover of 3,000 DM/ha would be roughly the height of a Guinness can (15cm) and 2,500 DM/ha would be roughly the height of a Coke can (12cm). Rotational grazing is dividing the pasture area into several small paddocks. That is a formula that NRCS uses with the particular size of hoop that I use in order to calculate the pounds of dry matter per acre. This will help identify any areas for reseeding (see panel). If your grass will not grow to Guinness can height, you can adjust the opening cover number to get an idea for your farm. Grazing Calculator is the brainchild of a dairy farmer, who wanted a fast and easy way for him and his workers to be able to do grazing related calculations. This rule helps the grazier determine paddock size according to the period of time he intends to let pass before grazing this paddock again. Mr Davies says his preference is to reseed in spring because the peak growth at this time affords the loss of fields/paddocks taken out for reseeding. There are lots of complicating factors and areas to get more in-depth, but to keep it simple, there are six steps to think about first: Mr Davies shared his top tips on getting going: Planning a rotation (route) for your stock will depend on various factors – how many cows you have and their size, influencing demand, how many bulling groups you run and your farm type. For the grazing season, it is unlikely in most parts to reach freezing temperatures, so the pipe can run above ground and be connected with push-fit attachments. This pasture can be grazed down to about four inches, at which point owners should move horses to another area. By Kathy Voth  /  October 12, 2015  /  3 Comments. At this height, the grass will recover well and have time to grow to the third leaf stage before it is grazed again. Continuous Grazing: Single pasture system and no rotation of livestock. Rotational grazing allows you to graze other livestock on a piece of land. There is little use in growing more grass if you are already understocked. Rotational burning to minimise patch grazing. However, 24 days is a good starting point because in many areas any longer than that and quality would start to deteriorate. Sorry, your blog cannot share posts by email. It might be one group of horses outside all day, or it could be that multiple groups of horses go out in shifts. throughout the grazing season. hoop x 100 conversion factor (cf) to get lbs./acre….other size hoops and CFs are listed here. A plan is key so that the first paddocks/fields shut can be the first grazed. It appears that the people doing intense rotational grazing are not breeding them. Rotational grazing, cell grazing and time control grazing. By the time the last paddock in the series has been grazed, the first has been rested allowing sufficient pasture growth for the paddock grazing sequence to commence again. These range from a large dairy farmer who rotationally grazes 1,600 head on his 2,100 acre all-grass farm to much smaller dairy, beef, sheep, hog, and even chicken operations. “For 50 yearling heifers, farmers are looking at 1ha (2.5ac) paddocks. If it isn’t grazed hard enough, you will get ‘stemmy material’ accumulating at the base of the plant, which leads to a decrease in quality. These six paddocks could each be split in half to create a rotation of 12 paddocks, each grazed for two days. Herefordshire sheep and beef farmer Richard Thomas is moving towards a lower-risk, lower-cost system, through regenerative farming practices, to ensure his farm can be profitable after BPS. If you are going to do that, I would build a small portable shelter you can drag from paddock to paddock or simple shelters for each paddock. For example, the ideal size paddock for a 40-cow suckler herd is about 2ha. To complete the full cycle (breeding, bull) puts a whole new pressure on electric fences with this method. The world of grassland management and different grazing systems can get very technical very quickly, but these steps are aimed to help those in their first year of moving to rotational grazing and trying to get more from grass. I got the hoop size and formula from NRCS a number of years ago. Simple rotational grazing is a system with more than one pasture in which livestock are moved to allow for periods of grazing and rest for forages. The goats, the cows, and now the pigs are all rotated around our property inside their own electric fences. 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. Absolutely zero common ground!!! “As a rule of thumb, for a 40-cow suckler herd with calves, paddocks should be 2ha or 5ac in size. For example, on a six-paddock system, if grass is growing rapidly and by the time you are grazing paddock number four, paddock one is back at optimum cover (Guinness can), then leave paddocks five and six and restart the rotation at paddock 1. In fact, the key to pasture productivity with any rotational grazing design is providing adequate rest periods for pasture recovery and being flexible depending on the season. If a herd is turned into a paddock when the pasture is 7 inches tall and taken off when the pasture is 4 inches tall, approximately 900 to 1000 pounds of pasture are available. ft. – 50 cf (as seen in the video) That hoop he is using appears to be a 1.92sq.ft. Naturally the size (sq.ft.) Published: 5 years ago on October 12, 2015, Last Modified: October 12, 2015 @ 7:12 pm. Rotational Grazing- Paddock Layout and Construction.

You don’t need to pull out and pound in the ground rod with each move. The secret is to graze the paddock in three days and grow it in three weeks,” she added. hoop (yes I know its a round hoop but the area is the same ). To calculate paddock size, multiply the suggested acres per AU by the AU in the herd. The “50” is a conversion factor for that particular size of hoop in order to calculate pounds per acre. If MIRG requires 33 cows per acre, that equates to 1,320 square feet per cow. Paddock Size = # of DM required/forage supply X residency period = _____acres Number of Paddocks = (30/residency period) + 1 = _____paddocks Total Acres Needed for 75% System = Paddock size X number of paddocks = _____acres Prescribed grazing management plan worksheet to be used with rotational stocking methods. When running several bulling groups, each group would have their own allocated area and their own set of paddocks, which they will rotate around. 1.92 sq. On a system with six paddocks grazed for four days, the first paddock would have 20 days’ rest for the grass to grow before it is grazed again. Livestock are moved frequently from paddock to paddock based on forage The likely result will be continued…, It has been a long slog politically, and here at Osgodby Grange, six weeks of hard work have gone into providing the Christmas kill. ft. – 10 cf. Rotational grazing increases the utilisation of grass grown, which allows you to increase stocking density in comparison to a set stocked system – a benefit if grazing land is in short supply or you want to expand the herd. Once the decision has been made to develop a rotational grazing system and the preliminary calculations are made, you should have some idea of the basic plan- how many paddocks or pastures will be needed and their approximate size. Dave. If reseeding is required, it can provide a very good return on investment. While gaining in popularity, this method of livestock management is very uncommon. Unless grass growth circumstances require it, you would not move the groups from one set of paddocks to another. Jonathon Rohrbach (right) implemented a change-up in his rotational grazing plans on his Edmonds County, South Dakota, ranch and made a few happy discoveries in the process. Creep feeding should first be assessed on whether it makes sense, financially, to the business because if stocking rate and grass growth match then additional feed should rarely be required. This design focuses on moving your netting so the energizer does not have to moved. There are many approaches and types of grazing that fall under the broad umbrella of rotational grazing. And water for each paddock. Rotational grazing is the practice of moving grazing livestock between pastures (often called paddocks) as needed or on a regular basis. Working on the Guinness and golf ball principle, this is 3,000 – 1,500 = 1,500 kg DM/ha. Not to mention having 2 paddocks being utilized at … There is lots of grass measuring equipment available – our buyer’s guide explains some of the options. Rotational grazing involves moving livestock through a series of paddocks so when they have finished grazing the last paddock in the series, the first paddock has … If a calf requires 2.65kg of dry matter a day and it is given 1kg of dry matter in creep feed, then its grass demand falls to 1.65kg of DM/day. However, a very rough figure can be worked out using 3% of combined cow and mature calf weight. But the simplest version is a free sward stick from AHDB. However, if the potential causes of poor paddock performance (eg. If a ley is not too old, overseeding might be a suitable option to rejuvenate it. Available cover per paddock divided by demand – 3,375/840 = 4.0. By having multiple areas or paddocks to graze, the stock will get a continual supply of high quality grass before returning to the first paddock. By Kathy Voth / October 12, 2015 / 3 Comments. I have seen different sizes and shapes. While this is usually the easiest way to manage turnout, it can be very hard on the forage plants and often results in overgraze… Once per day seems to be a desirable number in most of the literature. Based on these numbers, a total area of 13.5 hectares (33.4 acres) would be required for six paddocks. This is where you want grass to be before cows and calves enter the paddock. Mr Thomas runs…, A government decision to allow dedicated TB-restricted marts to run in high TB areas in Wales for at least 12 months has been welcomed by cattle farmers as another marketing…, An oversupply of quality spring barley is likely to continue next year, as the Covid-19 pandemic continues to stifle demand from brewers and distillers. Other hoops have different conversion formulas to use with them. This is key for anyone giving rotational grazing a try this year, to make it easier to get covers the following season. weight of forage within a.96sq.ft. Table 3 provides some suggested paddock sizes (acres per AU) for rotational grazing. If you have a farm with smaller fields, they might work as paddocks, or if your grass fields are larger, they may need breaking up with fencing. Firstly, Mr Davies would never advise reseeding a field without soil sampling it and checking it for compaction first. This guide is for beef suckler farmers who want to get more precise with their grazing, but don’t quite know how. Rotational grazing involves the frequent movement of groups of stock through a series of paddocks and allows small landholders to decide when and for how long a pasture will be grazed and rested. Throughout the season there will be fluctuations in grass growth and the system needs to adapt to that. The grazing periods should be as frequent as you can handle, no more than 5 days per paddock. Planned Rotational Grazing: Strategic moves every 3 to 10 days to allow for rest and recovery in grazed pastures. Diploid gives a greater ground cover, Always, without fail, put clover in – white clover for grazing and red clover for silage. Fence line would measure 40’x40’ for 1,600 square feet of grazing per paddock or 6,400 square feet for the whole system. Since our mature sheep are approximately 200 lbs, they will need 1/5th the space, or 264 sq ft. Small-Scale Rotational Grazing Keeping your cattle, goats, sheep, or chickens moving is the key to successful, controlled rotational grazing on a small homestead. If you already know your rotations from your residuals and your cover from your wedge, then you probably need to read no further. compaction) have not been fully investigated then return on investment could be severely reduced. When you know how much grass your farm grows, you can more-closely match the overall stocking rate to it. Flow rate is more important than trough size, to ensure the trough is full the majority of the time. More specific demand percentages can be used and are available from AHDB or independent advisors. They are recommended for a reason, For grazing, go for intermediate or late-heading perennials. As the calf grows throughout the season, this number will change. Rotational grazing describes the practice of rotating livestock through a series of paddocks. 9.6 sq. This is the available cover per hectare multiplied by the paddock size. Mr Davies’ tips on selecting seeds include: Water is the number one excuse for not going into rotational grazing because people think it is expensive to set up, but it can be done with a plastic trough and alkathene pipe. Intensive rotational grazing is a system with many pastures, sometimes referred to as paddocks. This saves time and effort. They are buying at 500 pounds and selling at 1000 pounds. Hope that this helps. One thing to note is the formula calls for % dry matter of the grass, not moisture. “And if you can do that, you should have a reduced need for additional, more expensive, feeds.”, See also: How rotational grazing increased beef daily liveweight gain. This means that you won’t have the staggered growth across paddocks that rotational grazers would typically see before turnout. Her twelve years at the agency allowed her to pursue her goal of helping communities find ways to live profitably AND sustainably in their environment. Therefore, in year one, you need to have an area/field where you can hold cattle for a time (approximately one week to 10 days) to let grass growth pick up in the first paddock/field you plan to turn them into. Have you been wondering how to decide the size of your paddocks when you’re setting up an intensive grazing system? And if you have 12 paddocks, each one will be grazed for two days.
