Conteúdo: 	A very important aspect of beef production is the breeding periods since it constitutes the foundation of the whole productive system. The objective of this research was to increase the productivity of the breeding herd using low inputs, which would make the openin g up of new areas for this activity more attactive. A brief description is given of the areas of study and a typical beef production system; emphasis is placed on evaluating the economics of adopting an improved breeding system at the farm level in the Cerrados of Mato Grosso do Sul. The internal rate of return was used as the investment criterion, taking into account the costs and benefits of the additional investment required for the improved system as compared to the traditional one. These two systems differ with regard to animal parameters, the area of cultivated pastures and the use of rural credit. In the improved system, rice is grown for three years prior to planting the grass. The herd was envolved to adapt to the carrying capacity of the pastures and took ten years to become completely stabilized. The grass used in the improved system was Brachiaria decumbens Stapf. The improved systems was found to be profitable, in real terms, as a result of the response of the animals to the cultivated pasture. The governmental credit policy of granting resources for beef cattle production at subsidized interest arates should be maiantained in order to make this activity attractive to the producers and to induce them to invest in an improved breeding system, thereby increasing their productivity and profits. At the same time, research should be intensified to find methods of establishing pastures at lower costs in order to decrease the volume of resources necessary.
