It is multiple moves per day and the high-stock density that differentiate mob grazing from other management intensive grazing (MIG) forms,â he says. The different grazing systems include continuous, simple rotational and intensive rotational. When done properly, pasture rotation can prevent overgrazing, aid optimal regrowth of plants and allow the same piece of ground to be grazed ⦠Under these conditions, the 100 cows would graze down 1.3 acres in 12 hours or 2.6 acres in one day. Marginal land Not all land can grow row crops. Source: Government of Saskatchewan Intensive Grazing Intensive grazing describes livestock and grass management practices that focus on increased levels of manager involvement, increased forage quality, increased meat production per unit area; and more uniform forage utilization. Iâll add one more: Historically, itâs very labor- and capital- intensive. It is believed that rotational grazing offers amazing results when used with different animals. Quick facts Producers use grazing to help reduce feed costs and make unproductive cropland productive. This is a presentation about the technique of intensive rotational grazing. Assume 100 1200-lb dairy cows eating 3 percent of their body weight grazing for 1/2 day on pasture with 2,000 lb of dry matter present per acre (Table 1) of which they consume 70 percent. ... (DM) per acre are available per inch of sward height. Created Date: 3/16/2010 12:01:50 PM The stocking rate remains 50 cows per 500 acres. So, besides cattle, you can also use pigs, sheep, meat birds, and laying hens. Benefits of grazing Cost The biggest cost in most, if not all, cattle production systems is feed. 20 acres (9,500 lb/ac) 9,500 = Letâs start with how many animals should be on our example farm. It is to be located in an area where winter weather conditions and soil types allow cattle to be housed outside all year. magazine: By âmob grazing,â most operators mean very high stocking densities per acre for very brief durations and very long recovery times.Notice there are three âveriesâ in there. Per the example, the number of stocker cattle you should graze is: 123.9 AUD / 0.8 AUE = 154.9 or 155 stocker cattle per day for 2.6 acres per day. It is multiple moves per day and the high-stock density that differentiate mob grazing from other management intensive grazing (MIG) forms,â he says. By Greg Judy During spring and winter, paddocks were wet and required lower stock densities. Use the same formula if you want to graze sheep. Managers practicing intensive grazing ⦠Thatâs in addition to grass that is only grazed once every 70 to 80 days. Table 3. And the operation uses a simple rotation grazing system in order to have 30 percent harvest efficiency. The herds graze one portion of pasture, or a paddock, while allowing the others to recover. The enterprise budget takes into consideration costs of labor, pasture, minerals, implants, marketing, veterinary, pumping water, interest, and ⦠These pasture systems and forages are a part of sustainable agricultural systems. high as intensive rotational grazing systems Advantages Highest forage production and per acre Stocking rates can typically be More even distribution of manure throughout the paddocks, better nutrient cycling Weeds and brush are usually controlled through grazing Provides more grazing options and reduces the need for The optimum MIG system provides the following major advantages: matter intake per cow-calf pair per day, could graze on 1.9 acres for 180 days. Mob Grazing Cattle Made Simple With a mob of cows, a paddock system, high-tensile wire, and electric fencing, you can cut hay costs, improve soil health, and maximize herd performance. Stock is shifted daily, giving each paddock up to 30 days of rest and recovery. Intensive agriculture, also known as intensive farming (as opposed to extensive farming) and industrial agriculture, is a type of agriculture, both of crop plants and of animals, with higher levels of input and output per cubic unit of agricultural land area. Minus the calculations, for 200 pound ewes (which are 0.2 AUEs), you should expect to graze 620 of these ewes on 2.6 acres per ⦠AU per acre, depending upon the grazing period and the number of cattle. A MOB system is characterized by ultra-high stocking densities (greater than 100,000 pounds of bodyweight per acre), short durations (one day or less between rotations) and long rest periods (usually at least 45 days of growth). Stock density was increased during summer and fall. Multiply the average sward height by the pounds of DM per acre inch to estimate yield in pounds per acre. In this system, animals are moved frequently at high stocking rates. In this model dairy, the farm is a carefully selected 100-acre piece of land purchased specifically for developing a grazing dairy. They use management intensive rotational grazing (MIRG), which results in higher grass production, higher stocking rates, and increased profits per acre compared to continuous grazing. ⦠Management-Intensive Grazing systems, of which there are many variations, can increase the yield of animal products per acre and, in most cases, net profit per farm. If the property was managed such that each of the 50-acre pastures were subdivided into 10-acre paddocks for grazing, stock density in each paddock would be five cows per acre (50 cows divided by 10-acre paddock), or 6,000 pounds per acre (1,200 pounds per ⦠âThe higher the density, with shorter grazing periods, the more uniform the urine/manure distribution will be. When cattle enter a paddock to graze, the leaves are easily trampled. If you donât have a large amount of land and you still want to raise a pretty large number of cattle, you should opt for rotational grazing. This statistic is based on the assumption that management intensive grazing is used, moving cattle every day and utilizing poly wire temporary fencing. Brett Williams Northwest College, facilities assistant. Paddock sizes based on grazing period and available pasture. âWhen you get the density up that high, the cattleâs appetite is incredible. Our goal was to produce a nearly year-round supply of medium to high quality forage. Rotational grazing can be used with ruminants such as beef or dairy cattle, sheep or goats, or even pigs. Others say it must be at least 500,000 lbs./acre to accomplish your goal. The bermudagrass was overseeded with rye and ryegrass, and all of the land was heavily fertilized (> 150 lb of actual nitrogen per acre). If you have the ability to have at least 1,500 to 2,000 lb of forage per acre, then you may be able to raise 100 calves. Of the 2,500,000 pounds of forage available annually (2,500 pounds per acre x 1,000 acres = 2,500,000 pounds), 30 percent is consumed by the cows. 3 Paddock 12 Paddock 24 Paddock----- ----- ----- Cow-calf pairs/acre 0.31 0.38 0.48 Grazing days - cows 225 212 215 Grazing days - calf 181 181 181 ADG - calf 2.27 2.30 2.03 Gain per acre - calf 126 156 176 Conception rate 95.0% 97.2% 90.0% Steers per acre 0.35 0.44 0.54 Grazing days-steers 88 88 88 ADG - steers 2.01 2.16 2.17 Gain/acre - steers 62 83 102 Returns per acre ⦠Title: Mob Grazing Mob Grazing Author: Boyd Kidwell Subject: High-density stocking builds profits back into th cattle business. âEven though I no longer own the cattle, I think rotational grazing under irrigation is still more profitable than corn right now, considering cattle prices,â he says. We changed stock density by increasing or decreasing cattle numbers. This equals 750,000 pounds of forage that is available per year on the ⦠Prior has been using intensive grazing on his 90-acre farm, Grazing Meadows in Brussels, Ont., for over 15 years now. Response by Nathan Griffith, editor Sheep! Itâs a system that amps up the intensity of intensive grazing. Management-intensive Grazing Management-intensive grazing is a system that divides large fields into smaller paddocks. A MOB system is characterized by ultra-high stocking densities (greater than 100,000 pounds of bodyweight per acre), short durations (one day or less between rotations) and long rest periods (usually at least 45 days of growth). Since our mature sheep are approximately 200 lbs, they will need 1/5th the space, or 264 sq ft. The length of time a paddock is grazed will depend on the size of the herd and the size of the paddock and local environmental factors. Mob grazing (MOB) is a more intensive type of rotational grazing. Table 3 provides some suggested paddock sizes (acres per AU) for rotational grazing. Many producers use grazing to reduce costs for their operations.
