It might be one group of horses outside all day, or it could be that multiple groups of horses go out in shifts. When running several bulling groups, each group would have their own allocated area and their own set of paddocks, which they will rotate around. ft. – 10 cf. Intensive rotational grazing is a system with many pastures, sometimes referred to as paddocks. And he says reseeding is not a job for year one because until you have assessed the balance between grass growth and stocking rate, it is pointless. These six paddocks could each be split in half to create a rotation of 12 paddocks, each grazed for two days. Working out demand with a bulling group of 40 600kg cows with 100kg calves at foot (amend numbers as suitable for individual farms): Demand of one cow – 3% of bodyweight (600kg) = 18kg DM/day, Demand of one calf – 3% of bodyweight (100kg) = 3kg DM/day. Absolutely zero common ground!!! 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. This saves time and effort. Equally important is the amount of grass left behind, which is called the residual. This rule helps the grazier determine paddock size according to the period of time he intends to let pass before grazing this paddock again. 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. Rotational Grazing Rotational grazing is a great tool for new entrants as well as established farmers, as it enables greater stocking densities. While gaining in popularity, this method of livestock management is very uncommon. 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. And it may be possible to plant a poorer paddock with a crop like turnips or kale for the winter and then reseed in spring, maximising the use of the area. Conversely, if grass growth is rapid then it may mean taking paddocks out for one rotation or more. There is lots of grass measuring equipment available – our buyer’s guide explains some of the options. 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. There are no really hard-and-fast rules, but some generalization is possible. 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. That hoop he is using appears to be a 1.92sq.ft. 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. 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. Available forage dry matter (DM) per acre varies. Naturally the size (sq.ft.) The secret is to graze the paddock in three days and grow it in three weeks,” she added. Other hoops have different conversion formulas to use with them. 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- Paddock Layout and Construction. If you already know your rotations from your residuals and your cover from your wedge, then you probably need to read no further.
