Feeding colostrum based on birth weight improves dairy calves’ passive immuniza...
Silva, Flávio; Silva, Severiano; Conceição, Cristina; Ramalho, Joana; Caetano, Pedro; Martins, Luís; Pereira, Alfredo; Cerqueira, JoaquimCalves are born agammaglobulinemic, and thus, they need an adequate volume of colostrum right after birth. Good quality colostrum can be limited in a dairy farm, depending on several environmental and management factors. Also, the right amount of colostrum that a calf should consume is not entirely defined. In this work, we aimed to study the effect of the volume of colostrum fed by kg of birth weight (BW) in t...
Falha na transferência de imunidade passiva em vitelos – avaliação no 1º, 2º e ...
Silva, Flávio; Ramalho, Joana; Caetano, Pedro; Martins, Luís; Conceição, Cristina; Pereira, Alfredo; Cerqueira, Joaquim; Silva, SeverianoIntrodução e objetivos: É cada vez mais comum a monitorização da transferência de imunidade passiva nas explorações leiteiras. O método de referência consiste na determinação por imunodifusão radial, da concentração de IgG sanguínea às 24h de vida, ocorrendo falha na transferência de imunidade passiva (FTIP) abaixo dos 10 mg/mL. No entanto, este método não está acessível à generalidade dos produtores. A medição...
Reimagining Wicked Problems Through Speculative Design: Collaborative Classroom...
Gorgel Pinto, António; Reaes Pinto, Paula; Figueiredo, Filipe; Ramalho, JoanaAbstract Design can be explored by various agents—professional and non- professional designers—in different areas, through processes, which represent the creative and social territories inhabited by those agents. Design thinking principles have been increasingly adopted by public and private organisations, from various sectors, to tackle complex problems and envision solutions. Speculative Design can play a fun...
From Dystopia to a Micro-Utopia: Societal Change Through Digital Design Innovation
Gorgel Pinto, António; Ramalho, Joana; Reaes Pinto, PaulaABSTRACT | This research paper combines socio-cultural sustainability with digital product design through a co-design and user experience (UX) approach. It draws attention to the unsustainable relationship between design and technology and proposes a problem-focused approach instead of a solution-focused one. The study showcases the Digital Experience Theatre (DXT), a creative tool influenced by Augusto Boal’s ...
Serum and saliva immunoglobulin (immunoglobulin G, immunoglobulin A, and immuno...
Silva, Flávio; Lamy, Elsa; Conceição, Cristina; Cerqueira, Joaquim; Ramalho, Joana; González-Cabrera, Marta; Caetano, Pedro; Martins, LuísThe transfer of passive immunity is essential to ensure the health and welfare of new-born calves. Although the dynamics of serum Ig concentrations in these animals are well-described, data about saliva Ig are limited. This study aimed to evaluate serum and saliva Ig (i.e., IgG, IgA, and IgM) concentrations during the first week of life in healthy and sick calves. Blood and saliva samples were collected from 20...
Predicting Body Weight in Pre-Weaned Holstein–Friesian Calves Using Morphometri...
Silva, Flávio; Carreira, Emanuel; Ramalho, Joana; Correia, Tomás; Meira, Marília; Conceição, Cristina; Silva, Severiano; Pereira, AlfredoRegularly weighing calves helps to assess the efficiency of the rearing period and contributes to animal welfare by allowing more precise feeding and medication application in dairy farming, but many farmers do not weigh their calves regularly. Improving the feasibility of this process is, therefore, important. The use of morphometric measurements has been used to estimate the weight of cattle. However, many st...
Predicting Functional Recovery of Spinal Cord Injured Patients in Physical Medi...
Oliveira, Diana Rocha; Moura, David; Silva, Sara Ribeiro; Ramalho, Joana; Romeiro, Isabel; Azevedo, Ana Sofia; Guimarães, Bruno; Toste, SofiaIntroduction: Evaluate the role of rehabilitation and define which variables are predictive of functional recovery in patients with spinal cord injury (SCI), through the measure of independence in spinal cord injury (SCIM). Methods: This is an observational, analytical and retrospective study, developed in a peripheral hospital center for acute patients. The files of all patients hospitalized in this hospital, ...
Hirayama Disease: Report of a Successful Clinical Case
Moura, David; Martins, Rafael; Oliveira, Diana; Romeiro, Ana; Azevedo, Sofia; Ramalho, Joana; Ribeiro Silva, Sara; Cubelo Pereira, PedroThe authors present a case of Hirayama’s disease in a 17- year-old boy who had been complaining, for a year and a half, of pain and unilateral motor deficits in the 4th and 5th fingers of the right hand with progressive functional impairment. On examination, atrophy of the ulnar anterior aspect of the forearm, and right thenar and hypothenar regions was evident, associated with a deficit of muscle strength in t...
Efeito da diarreia neonatal na resposta termorregulatória de vitelos em stresse...
Silva, Flávio; Conceição, Cristina; Cerqueira, Joaquim; Andrade, Ana; Azevedo, Inês; Pedro, Sofia; Ramalho, Joana; Fernandes, Beatriz; Pereira, AlfredoO stresse térmico pode influenciar negativamente a saúde e bem-estar do vitelo. Principalmente no primeiro mês de vida, o vitelo é extremamente suscetível a doenças como a diarreia neonatal (DN). Verifica-se um aumento da probabilidade de ocorrência e da severidade da DN com o aumento da temperatura ambiente (TA), devido a um conjunto de fatores relacionados com a fisiologia do vitelo e com as características a...
Evaluation of the birth impact in the newborn dairy calf using ethophysiologica...
Silva, Flávio; Pedro, Sofia; Azevedo, Inês; Ramalho, Joana; Caetano, Pedro; Martins, Luís; Cerqueira, Joaquim; Silva, Severiano; Conceição, CristinaThe calving moment is one of the most stressful events in the calf’s life. Therefore, evaluating the level of the birth impact in the calf can provide valuable information for both nursery and research activities. The evaluation can be performed by measuring calf’s vitality, or vigor, using ethologic and physiological parameters. However, there is a lack of general agreement regarding which measures are more su...
