The objectives of this study were to develop a software that accomplishes both the dimensioning and evolution of cattle herds and develop a tool which makes it possible for the user to perform simulations with production systems of milk and or beef. The language employed was CA Clipper. The routines have been developed in a conversational form, with an access to the several programs by means of self-explicative menus. The developed system can aid both the technician and the raiser in dimensioning and evolution of a cattle herd with precision and outstanding rapidity; it allows to the user to perform a number of simulations; and it is considered an important tool in the assistance to decision-making.
