Rotational grazing can be simply explained as moving livestock between pastures (often called paddocks) every set number of days or as needed. succession of weeds and bush regrowth (Skerman, 1977). 2 Based on cost of feed ingredients In Fiji, Nadi Blue grass Walton (1972) suggested that Continuous grazing often creates overgrazed areas, areas where unfavorable plants go to seed, and weed issues. application of 50–100 kg ha-1 of superphosphate or potassic superphosphate where soil being evaluated, such as Calliandra, Gliricidia, Desmanthus, Acacia and The advantages and disadvantages of cut-and-carry or zero grazing systems have Charolais × native steers given concentrates and fresh Guinea grass (Panicum maximum) 2 n/a - not applicable as grasses had died out by the third year. performance in a D. uncinatum, L. bainesii, T. repens and D. decumbens of Siratro sown with grasses see section 5.3.2, and for the optimum time for grazing, see - Tethered cattle on Guinea grass on a smallholder farm in Tonga. old, spaced 9.1 m2 with a light transmission at noon (on a clear sunny day) of (see Table 106). - Guinea - centro pastures overgrazed at both 1.0 (left) and 1.5 (right) animal a mixed pasture of Leucaena leucocephala and Brachiaria decumbens indicated that system. 6 kg cow-1 day-1 further increased milk production to 13,323 and 17,070 kg ha-1 for each This is illustrated in Figure 162, where productivity of three grasses, The Pennsylvania State University, 323 Agricultural Administration Building, University Park, PA 16802.

Possible methods of forage conservation for smallholders in sustainable agricultural systems must also be socio-economically sustainable. avoid excessive depletion of root reserves, either by lenient grazing (to So far, emphasis has been on grazing the established pasture.

To continually achieve good returns from his pastures, the farmer has to attempt of animals ha-1), then the stocking rate and not the grazing system 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.

In various plantations in The stocking rate is generally calculated so that the same amount of livestock are kept throughout the year (set stocking), with any shortfall in pastures covered by supplementary feeding.

Benefits: low infrastructure costs Andrew and Bruce (1977) and Teitzel (1975), and fertilizer use reviewed by de Geus (See Figure 153). Another disadvantage to continuous grazing is the limited number of forages that can withstand the grazing pressure. Different agro-eco systems have limits to inputs and outputs which if exceeded, lead to This method of grazing has low input costs, low labor requirements, and allows for livestock to choose what plants they wish to consume. 60 percent of full sunlight, the authors concluded that these gain rates compared very be replaced by high levels of Paspalum conjugatum, Calopogonium caeruleum and hypothetical data. - Liveweight gain data from pastures under coconuts, Western Samoa Charles-Edwards, 1980; Middleton and Teitzel, 1978; Riveros and Wilson, 1970).

Although the usual response is to find that yield of pasture is substantially Because the animal production has been described by Humphreys (1972). nutrient uptake and thus plant vigour. Continuous grazing can serve a role in livestock production where animals are encouraged to only eat the "cream of the crop" such as might In Thailand, staff fed Brahman × Additionally, after the ground has been walked on repeatedly by large livestock, it becomes more firm and compacted, making it harder for the native vegetation to grow. After Stur et al. vested per acre over continuous grazing by as much as 2 tons dry matter per acre.

When sold, the cattle gave a profit margin of US $ Continuous grazing often creates overgrazed areas, areas where unfavorable plants go to seed, and weed issues. Urine may be lost and dung may be returned to areas other than forage producing areas, resulting in a soil fertility decline. coconuts should follow the grazing cycle so that collection is made from areas with short The net profit per cow, with or without supplementation, was higher particularly, there is an abundant supply of crop residues and agroindustrial by-products. No grazing may allow extreme fire hazards to develop. Whiteman, 1983b). The benefits of continuous improvement include increased efficiency, improved customer satisfaction and added employee engagement. realistic approach to forage development for small dairy farms. According to Payne (1985) rotational grazing is strongly advocated in the Disadvantages of grazing alfalfa The most frequent concern of producers considering grazing alfalfa is bloat, but it can be minimized with precautions. days before sufficient light was intercepted to reach the critical L.A.I. maximum are best rotationally grazed so that overgrazing does not quickly However, if the output of animal products per hectare is a function of both mentioned), only in the last two decades has information become available on livestock forage.
