Suplementação de bovinos de corte terminados em pastagens tropicais

Abstract

The objective at with this revision to compile information on the supplementation in bovine finishing in pasture tropical during the dry period and of the waters. The uses of the supplementation of bovine finished in tropical pastures they become indispensable, because the pastures don't supply the nutrients demanded by the animals in an appropriate way during the year. This technology allows correcting diets unbalanced, to increase the efficiency of use of the pastures, improving the animal acting, to shorten the reproductive cycles, of growth and termination of the bovine ones and to increase the capacity of support of the pastures, increasing the efficiency of use of the pastures in your production pick. During the period of the drought, multiple supplements can be supplied in close amounts to 1.0 kg/animal/day, assisting to the demands of nutritious limits to provide won low. In the period of the waters, moderate amounts (0.3 to 0.6% of body weight) of energy supplement or energy proteineous they can result in increase in the earnings of medium diary of the order from 0.15 to 0.4 kg/animal/day. Supplementation energetics supplies the energy nutrients aiming at larger earnings of body weight, already the proteinaceous in the dry period is a tool for different acting levels and maintenance, impeding weight loss, the mineralization with salt proteineous, with the intention of maintaining the weight or to generate won low. For the termination to be rendered, it is necessary that the animal has a medium acting, along your life, from 600 to 650 g a day. The supplementation shows to be a great technique for the cattle farmers of Brazil, with your use it is possible to abate more precocious animals with a better quality of carcasses with the conservation of the pastures obtaining like this available forage for the bovine ones avoiding losses with deaths during the dry period.
