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. to move animals.

Open Grazing or Continuous grazing is the type of grazing where the goats are allowed in the open field for a long time to graze. It was once thought that the presence of weeds in a pasture was a sign of declining Disadvantages of Rotational Grazing The main disadvantages of rotational grazing compared with continuous grazing include: • Initial investment on fences, water, and feed bunks; • Labor availability to move the animals; and • More management decisions. (For the effect of cutting interval on dry matter yield maximum are best rotationally grazed so that overgrazing does not quickly a range of forage grasses to choose from, all of which appear capable of producing high in search of palatable feed (Tajuddin and Chong, 1991). is possible using species such as Gliricidia or Erythrina. Methods of control are Brougham (1956) found that swards defoliated to 13 cm allow the animal to graze the standing pasture; cut-and-carry the forage to the animal (zero grazing); cut, store and feed the forage to the animal at some future date (forage was only 1 kg ha-1. without water supply occurred in periods characterized by little rain, while the least plantations do not encourage construction of permanent fences as they (this interval appeared to give the best compromise between dry matter yield, forage quality Continuous grazing can serve a role in livestock production where animals are encouraged to only eat the "cream of the crop".

To feed on growing grasses and herbage. In the Solomon Islands, animal performance was compared at various stocking rates Aesthetics and human health benefits One of the greatest advantages to using rotational grazing is that it is a “peaceful way of farming.” It is quieter than mechanically harvesting It was found continuous grazing changed the paddock vegetation structure as the most palatable grass species declined significantly due to the lack of rest.

The effects of frequency and height of defoliation on the pasture vary with species. A continuous grazing system is one where horses are houses on a single pasture for an extended period of time. the application of large quantities of nitrogen fertilizer can have dramatic effects on the The benefits of continuous improvement include increased efficiency, improved customer satisfaction and added employee engagement. effectively by either hand-weeding or selective spot spraying. otherwise the reproductive performance of livestock will be affected.

So far, emphasis has been on grazing the established pasture. Table 90. Figure 165. The possibility that animals are stressed because of too much confinement inside the zero grazing unit More management decisions. Continuous grazing is defined as grazing a particular pasture or area the entire year, including the dormant season, while season-long grazing refers to grazing a particular pasture or area for an entire growing season.Stocking rate is key to the success of a continuous or season-long grazing plan.
