It is observed, therefore, that, although the bovine flock not to have grown significantly in the number of heads, occurred productive performance better and increase in the tax of enjoys. How much to the systems of adopted production, the use of the natural Nelore race predominates with sum. adoption of station of sum still is sufficiently incipient. Currently, in savannah environment, the extensive creation with use of native pasture predominates and only mineral suplementao. The natality tax is inferior 60% with weans of the year-old calves occurring to the 12 15 160 months when they reach kg of alive weight. In general, in this situation the year-old calves are vendidos for creators who carry through the recria and fattening in pasture cultivated in forest area. A minority of creators of the savannah areas uses the native pasture, but they possess grass cultivated for strategical use with some animal categories.
In this situation, the cows in gestation remain in native pasture receiving, at the time dry, suplementao with multiple mixture contend NNP. By occasion of the pario the cows in lactation are taken for pasture of Brachiaria (humidicola B. or B. decumbens) and receive suplementao with multiple mixture. The year-old calves have access to the multiple mixture with 20% of rude protein, in cocho private (creep feeding), installed to the side of the cochos for suplementao of the cows. In such a way it is possible to wean year-old calves with seven the eight months and 160 the 170 kg of alive weight. For occasion of it weans, the recria animals are taken for pasture of andropogon (Andropogon gayanaus) with estilosantes or massai (Panicum maximum) with estilosantes and has access the multiple mixture with 25% of PB, whose mineral salt possesss protein and energy, chromium source.
