PRODUÇÃO AGRÍCOLA E ANIMAL EM CONSÓRCIO TRIPLO COM MILHO, BRAQUIÁRIA E FEIJÃO-GUANDU

Abstract

The present work aims to evaluate, the system of animal production in triple intercropping of corn, brachiaria and pigeon pea, both in grazing after harvest and in confinement, using total area silage and wet grain silage. In the 2016-2017 harvest, the triple consortium of corn + brachiaria + pigeon pea was equally spread over the entire area (9 hectares). The combination of harvesting systems in the area determined the three treatments: harvesting the total area for silage production; wet grain harvest for silage production; and area without harvest. For the first grazing and feedlot, 30 male Nelore bovines were used. After a rest period of 119 days from the first grazing areas, it was possible to carry out a second grazing with F1 bulls (Nelore x Angus). Data analysis was performed using ANOVA and principal component analysis. The results indicated that in the short term, the area with the highest animal productivity was the area without harvest, however, in the long term, this area showed less efficiency of use while the area harvested for total silage showed the best result, being used both in grazing and in feedlot. The results observed here can serve as a guide for decision making according to the economic scenario.
