O Montado (Dehesa) é um sistema agro-silvo-pastoril do Sul da Península Ibérica. Inclui pastagens, árvores (sobreiro e/ou azinheira) e animais domésticos (ruminantes ou porcos). A Agricultura de Precisão permite otimizar a sua gestão incrementando a sustentabilidade económica, ambiental, social e cultural. Atendendo que as parcelas de montado apresentam elevada heterogeneidade, o uso de tecnologias que permitam...
Rearing intact male pigs may lead to an off-odor and flavor in meat and fat known as boar taint, especialy in animals slaughtered at older ages and high body weights (BW). This is a particular issue for a portuguese local breed, the Alentejano (AL) pig. To address this, males from this breed are generally physically castrated. However, with the potential prohibition of this surgical procedure in the European Un...
The Alentejano pig, a local portuguese breed, is known for its high-quality PDO and PGI meat and meat products. Traditionally, these animals are reared to older ages and heavier weights, with male castration used to prevent boar taint, which adversely affects meat flavor and odor, as well as to reduce aggressive behaviors. With the impending ban on surgical castration within the European Union, alternative solu...
The Montado, a dominant agro-silvo-pastoral system in Southern Portugal, features rainfed pastures primarily composed of legumes and grasses. Portuguese pasture area has expanded over the last century for economic, environmental, social, and cultural reasons. These pastures offer low-cost forage and improve long-term soil fertility through animal manure incorporation, enhancing soil organic matter, and legumino...
A Agricultura de Precisão visa auxiliar os gestores nas tomadas de decisão do quotidiano. Para isso, é fundamental o conhecimento do solo e da parcela. Nos últimos anos procurou-se relacionar parâmetros do solo com a saúde humana, nomeadamente com a incidência de certas doenças. No caso dos animais a pasto, condições como a tetania dos pastos ou carência de magnésio são frequentemente associadas a pastos de fra...
The application of dolomitic limestone is a recommended practice for improving pastures established on acidic soils. On the other hand, pasture availability should determine the adjustment of the biotic load. The aim of this study is to evaluate the potential of pasture plant community composition as an indicator to assess the effects of intensification strat egies in the Montado ecosystem, specifically soil pH...
O montado é um ecossistema característico dos países de clima mediterrânico, representando o Alentejo a região de maior expressão em Portugal. É um sistema misto, agro-silvo-pastoril, que suporta a produção pecuária extensiva com baixos encabeçamentos animais. Nas últimas duas décadas a agricultura sofreu um forte impacto tecnológico associado ao conceito de Agricultura de Precisão. Este conceito corresponde a ...
The economic and environmental sustainability of extensive livestock production systems requires the optimisation of soil management, pasture production and animal grazing. Soil compaction is generally viewed as an indicator of soil degradation processes and a determinant factor in crop productivity. In the Montado silvopastoral ecosystem, characteristic of the Iberian Peninsula, animal trampling is mentioned a...
Deferred grazing (DG) consists in adapting the number of animals and the number of days grazed to the availability of pasture. Compared to continuous grazing (CG), which is based on a permanent and low stocking rate, DG is a management strategy that aims at optimizing the use of the resources available in the Mediterranean Montado ecosystem. This study with sheep grazing, carried out between 2019 and 2021 on a ...
Extensive livestock production systems based on improved pastures under Montado of Holm oaks represent an approach in line with the challenges of sustainability and biodiversity. The increasing incorporation of technologies in the monitoring of this ecosystem allows for a better knowledge of the spatial and temporal variability and, consequently, a more economically profitable management. In this study, between...
