The Campos, grassland with few trees or shrubs except near streams, lies between 24°S and 35°S; it includes parts of Brazil , Paraguay and Argentina , and all of Uruguay . Grassland -based livestock production is very important, based on the natural grassland that covers most of the area. Stock rearing is on large, delimited holdings and is commercial. Both tussock-grass and short-grass grasslands occur.
There is a dominance of summer -growing C4 grasses, with C3 grasses associated with the winter cycle. Cattle and horses were introduced in the seventeenth cen-
tury and sheep in the nineteenth. Production is based on spring –summer growing grassland, with little use of sown pastures. Beef cattle predominate; sheep are mainly for wool, but some lamb is produced. Limited winter production and poor herbage quality are major limiting factors in livestock production. Soil phosphorus is generally low and this deficiency affects stock. Campos pastures are highly responsive to fertilizers, which can modify the specific composition of natural grassland; application of phosphate increases legume cover and the phosphorus content of forage. Fattening off grass can take up to four years; intensive fattening of younger stock uses some sown pasture . Sheep may be grazed with breeding herds of cattle. Exotic temperate legumes can be grown and may be over-sown into native swards after land preparation; once established, legumes encourage the development of winter grasses. This paper shows that it is possible to improve forage consumption from natural grasslands, implying an annual increase of 784 000 tonne of liveweight, without cost, in Rio Grande do Sul alone, through a strategy of high forage offer to the grazing animal, which also optimizes forage accumulation rates in the pasture.
