Extensive Sheep and Goat Production: The Role of Novel Technologies towards Sus...
Silva, S.R.; Sacarrão-Birrento, L.; Almeida, M.; Ribeiro, D.M.; Guedes, C.; Montaña, J.R.G.; Pereira, A.F.; Zaralis, K.; Geraldo, A.; Tzamaloukas, O.Sheep and goat extensive production systems are very important in the context of global food security and the use of rangelands that have no alternative agricultural use. In such systems, there are enormous challenges to address. These include, for instance, classical production issues, such as nutrition or reproduction, as well as carbon-efficient systems within the climate-change context. An adequate response...
Estudos de Eventos Extremos de Chuva na Bacia Hidrográfica do Rio Una
Oliveira, Regina; Silva, S.R.Em junho de 2010 chuvas torrenciais caíram sobre a Zona da Mata de Pernambuco, causando danos econômicos,a destruição de cidades e perda de vidas em várias cidades.As áreas mais atingidas no estado estão localizadas na Bacia do Rio Una. Mudanças no padrão de precipitação têm um impacto direto sobre os recursos hidrológicos ciclo e água. As projeções futuras para o impacto das alterações climáticas apontam para ...
Gerenciamento de risco de enchente: o caso Palmares
Amorim, G.; Silva, S.R.Os acontecimentos recorrentes de enchentes na área do município de Palmares, principalmente os de maiores intensidades no ano de 2010, causaram sérios prejuízos à população. Diante desta realidade este trabalho visa levantar subsídios para análise e descrição das interações entre aspectos geofísicos e fatores urbanos, considerando que os desastres ambientais não se resumem a ação da natureza. Ações humanas de ...
Real-time ultrasound (RTU) imaging methods for quality control of meats
Silva, S.R.; Cadavez, VascoIn this chapter the use of real-time ultrasonography to predict in vivo carcass composition and meat traits will be reviewed. The chapter begins by discussing background and principles of ultrasound. Then aspects affecting the suitability of realtime ultrasonography and image analysis for predicting carcass composition and meat traits of meat producing species and fish will be presented. This chapter also provi...
Development of a rapid and simple approach for kid carcass evaluation by vídeo ...
Monteiro, A.; Teixeira, Alfredo; Azevedo, Jorge; Lourenço, Ana Luísa; Dias-da-Silva, A.; Silva, S.R.objective of this work is the development of a simple and cost-effective video image analysis (VIA) system to evaluate kid carcass in small slaughter units. To achieve this objective a trial was conducted with 42 kid carcasses (6.6±2.6 kg) and models to predict carcass composition from VIA were established. While the carcasses were hanging in the gambrel an image of the dorsal view of each carcass was obtained ...
Prediction of apparent digestibility of hays from natural pastures of the North...
Galvão, Lurdes; Guedes, Cristina M.; Rodrigues, M.A.M.; Silva, S.R.; Valentim, Ramiro; Moreira, Olga; Ribeiro, José Ramalho; Sequeira, C.A.In the Northeast region of Portugal hays from natural pastures are traditionally used as the main feed during the period of drought and the evaluation of its nutritive value is essential. The aim of this study was to predict the apparent organic matter digestibility (OMD) of 21 hays from natural pastures based on chemical composition, pepsin-cellulase solubility of organic matter (OMS) and in vitro organic matt...
