Production potential of beef cattle in tropical pastures: a review
Abstract
The expression production potential represents the maximum amount of products that can be obtained per unit area. However, what is the maximum amount of product that can be obtained in a pasture area? To answer this question, it is necessary to understand the factors related to forage accumulation, grazing efficiency, chemical composition of the forage plant, forage intake and nutritional requirements of animals, management, genetics, and management of the production system. The average annual productivity of beef cattle in Brazil is approximately 120 kg of body weight (approximately 60 kg of carcass) per hectare. This index is below the parameters reported in the literature. Adequate management of pastures with tropical forages usually provides a stocking rate above one animal unit (450 kg) per hectare. The increase in the stocking rate, combined with high individual body weight gain, provides high productivity, which may exceed 1260 kg of body weight (approximately 630 of carcass) per hectare per year. The production of beef cattle in tropical pastures has a high response potential with regard to the adoption of technologies to increase productivity indices.
Keywords: beef cattle, intensification, productivity, stocking rate, weight gain.
