Pastejo Rotacionado Versus Contínuo: Dinâmica dos Sistemas.

Abstract

Brazil stand out from it is competitors for presenting grassland as the basis of production. However, because the extensive production regime predominates, Brazilian livestock farming has a great challenge to the degradation of pastures, a factor that negatively impacts the sustainability of the productive system. The use of grazing systems aimed at the adequate growth of the forage plant, the good animal performance and the improvement of the physical, chemical and biological of the ground is fundamental for the evolution of Brazilian cattle ranching. In this sense, it is worth to make a theorical and comparative analysis of the functional characteristics of both systems of production to the pasture, more employees, the continuous and the rotated. This will allow an assemblage of information regarding the particularities of each system. Pasture management is a set of unit area, according to the exploration objective. The system of continuous grazing, extensive and with low animal load/area (stocking), usually less than1,5 UA per hectare, is inefficient from the ecological and economical point of view, even presenting low production costs. The rotational system has allowed intensification of meat production and increased profitability of the activity. This is often due to the greater use of technological resources then to the isolated effect of adopting the system. The producer, when migrating from the continuous grazing to the rotated grazing, implements in your propriety, technics like corrections and ground fertilizing, irrigation, integrations of livestock and tillage, which allow the cultivation of more productive forages and the breeding of animals with better genetic potential. Thus, the rotational stocking method, when done correctly will be more efficient than continuous stocking, by promoting greater and more advantageous animal production, increasing the efficiency of pasture utilization, and allowing better control of parasites. However, because it is more complex, the implementation of this system requires greater control and dedication on the part of the producer. Normally, rotational grazing yields the lowest individual gain per animal, which is compensated by the gain/area.
