Pasture potentialities in family farming production systems in Los Ríos province, Ecuador. I: Winter / Potencialidades de pastagens em sistemas de produção da agricultura familiar na província de Los Ríos, Ecuador. I: inverno

Abstract

With the objective of determining the potentialities of grasses that allow improving the management of family livestock production systems in Los Ríos province, Ecuador. during the winter a study was carried out in The study was carried out in areas and the Laboratory of Ruminology and Nutritional Metabolism of the State Technical University of Quevedo, located in the Experimental Campus. "La María", km 7 1/2 of the Quevedo Mocache road, Los Ríos, Ecuador. The species used in the livestock systems were selected to carry out studies of the productive behavior (total biomass, total DMY, of leaves and stems) quality ( DM, CP, ash, OM, P, Ca, DNF, DAF, ADL, Cel, Hcel, CC, IVDMD, ISDMD, OMD, ME and NEL), to which an analysis of conglomerates to group the species with similarity. In the conglomerate analysis for grasses, three and five groups were formed, in trees and shrubs three groups, for summer and winter. All this information would contribute to the design of technological alternatives for sowing, establishment, management and use of its biomass as a food source where the productivity and sustainability of the ecosystem are minimized It is recommended to carry out new research to evaluate the impacts of the proposed technological alternatives on livestock production and ecosystem
