Pastagens de altitude: caracterização de uma exploração na região da Guarda
| Resumo: | This thesis studies three different pastures -one natural (PN), one sown 30 years ago (PMA) and one sown this October (PMN)- in the Serra da Estrela (Portugal). Cages with 1m2 were placed in all three pastures. The plant material was collected from these cages three times: two in April of 2014 and one in May of 2014. The chemical composition of the biomass- dry mass, crude protein and fibre (NDF,ADF and ADL)- was analyzed in the laboratory to estimate the nutritive value of the pastures. PMN had the higher nutritive value. This higher value is due to the fertilizations done in September of 2013. PN and PMA could improve their nutritive value with some changes in the pasture utilization by animals and by correcting the pH of their soils. The results of this study indicate that Quinta do Ordonho has species with good forage potential that should be maintained. |
