This study aimed to evaluate the dynamics of the association of ‘capim-de-raiz’ (Chloris orthonoton Doell) and alexandergrass [Brachiaria plantaginea (Link) Hitchc], as for persistence and production. Gathering of botanical material, evaluation of botanical composition and forage mass were realized in deferred native pastures. To estimate forage mass, a randomized block design with four treatments was used, consisting of 60, 90, 120 and 150 days of deferring and five replications. The botanical composition was expressed as a percentage of the total. Ten […]

This work aimed to demonstrate the application of a computer system (Sistema Viçosa de Formulação de Rações) in the recommendation of feed supplements for beef cattle with 200 and 400 kg of body weight, on different pasture deferring and utilization periods. In order to an animal of 200 kg of body weight achieve 1 kg of daily gain in a pasture deferred in February and used in June or September, or deferred in April and used in June or September, […]
