Long-Term Physical Activity Modulates Lipid Metabolism and Gene Expression in M...
Martins, José Manuel; Albuquerque, A.; Silva, D.; Neves, J.; Charneca, R.; Freitas, A.This study examined the effect of long-term physical activity during the finishing period on meat and fat quality, and metabolic gene expression in obese Alentejano (AL) pigs. From 87.3 to 161.6 kg BW and for 130 days, eighteen pigs were assigned to either individual pens without an exercise area (NE, n = 9) or an outdoor park with an exercise area (WE, n = 9). Both groups received identical commercial diets at...
Alpha-tocopherol content on the semimembranosus muscle of Alentejano pigs reare...
Neves, J.; Freitas, A.; Martins, J.; Nunes, J.This trial was undertaken to determine the effect of the rearing system (intensive vs. extensive) over the content of antioxidants (alpha-tocopherol) in the meat of Alentejano pigs. Sixteen Alentejano pigs with an average body weight (BW) of 60 kg were divided in two groups: Group I (n=10) was allocated in open-air individual pens, while Group II (n=6) was maintained in a 3 ha natural pasture. Both groups were ...
Efeito de uma dieta rica em fibra no crescimento, características da carcaça e ...
Martins, J.M.; Charneca, R.; Albuquerque, A.; Neves, J.; Freitas, A.; Costa, F.; Marmelo, C.; Ramos, A.; Martin, L.Este estudo visou avaliar em suínos Alentejanos (AL) os efeitos do sexo (animais castrados vs. inteiros) e de uma dieta de engorda rica em fibra no crescimento e qualidade da carcaça e gordura. Esta dieta experimental, com leguminosas produzidas localmente e subprodutos agroindustriais, tinha como finalidade reduzir os compostos causadores do sabor e odor a varrasco (“boar taint”) em machos inteiros. Usaram-se ...
Extended- Range Marine Unmanned Surface Vehicles for Border Surveillance Missions
Fernandes, J. F. P.; Branco, P. J. Costa; Marat-Mendes, R.; Póvoa, R.; Teodoro, P.; Neves, J.; Marques, H.; Pinheiro, P.; Afonso, P.; Serrano, D.This work focuses on the development of extended-range marine unmanned surface vehicles (USV) for border surveillance missions. USVs present many advantages for marine applications due to their energy-saving capabilities and lack of in-board pilot needs. Nevertheless, due to their small scales, USVs often present reduced mission ranges. In order to overcome this handicap, this work proposes the application of i...
The impact of gamification on consumer engagement with brands: Empirical evidence
Neves, J.; Oliveira, M.; Bacalhau, L. M.; Viseu, C.This study investigates the impact of gamification on consumer brand engagement among Portuguese gamers, addressing a significant gap in empirical research within this demographic. While gamification is known for enhancing brand engagement and loyalty, limited evidence exists in the Portuguese market. Using a quantitative approach, data were collected from 485 Portuguese gamers and analyzed through covariance-b...
Insights from the EQUALS4COVID19 study on migrant mental health in Portugal: A ...
Alarcão, V.; Candeias, P.; Stefanovska-Petkovska, M.; Neves, J.; Pintassilgo, S.; Machado, F. L.; Santos, O.; Virgolino, A.; Santos, R. R.Background The COVID-19 pandemic and related disruptive consequences in the economic, health, and educational sectors have impacted people’s lives, contributing to a context of increased economic and social vulnerability. The pandemic has revealed and accentuated social inequalities and discrimination based on racial or ethnic origin. This study aimed to contribute to the promotion of the mental health and well...
Varying response of bacteria and nematodes to environmental conditions of Sado ...
Vieira, S.; Vicente, C.; Neves, J.; Martins, M.; Adão, H.; Sroczynska, K.Sediment microbiome and benthic nematodes are indispensable in regulating benthic estuarine ecosystems and knowledge on their distribution patterns is essential for understanding of benthic food webs dynamics. However, simultaneous ecological analysis of bacteria and nematodes communities are seldom made, whereas the question if there exist a congruence between both taxonomic groups in their responses to differ...
Spatial distribution patterns of microbiome and free-living benthic nematodes i...
Soraia, V.; Sroczynska, K.; Martins, M.; Costa, M.H.; Neves, J.; Adão, H; Vicente, C.Sediment microbiome has an essential role in regulating ecosystem functions, not only regulating primary productivity and nutrient cycling but also shaping trophic interactions with higher trophic levels [1]. While the importance of microbiome in terrestrial soil systems is being highly recognized, its role in marine aquatic environments remains much less studied [2]. Microbiome can be highly affected by bottom...
Outdoor finishing of intact male pigs of local breed on a high fibre diet: effe...
Martins, J.M.; Charneca, R.; Varino, R.; Albuquerque, A.; Freitas, A.; Neves, J.; Costa, F.; Marmelo, C.; Ramos, A.; Martin, L.Thirty male pigs of the Portuguese Alentejano (AL) breed raised outdoors with ad libitum water and feed were used to test the effects of a new high soluble dietary fibre feed on animal performance and carcass traits. From 40 to 130kg body weight, surgically castrated (group C) and intact pigs (groups I and IE) were fed with commercial feeds. From 130kg until slaughter (160kg), groups C and I ate a commercial di...
Loin and fat quality of Portuguese local Alentejano and Bísaro pigs and their c...
Martins, J.M.; Albuquerque, A.; Rodrigues, M.J.; Neves, J.; Freitas, A.; Nunes, J.T.; Charneca, R.Alentejano (AL) and Bísaro (BI) Portuguese local pig breeds cohabited in Ribatejo region for some time. Their crosses (RI pigs) and the products obtained, although appreciated, disappeared in the 1950’s without being scientifically evaluated. To assess the meat quality of RI pigs, castrated males from AL, BI, ALxBI and BIxAL genotypes were studied within the framework of the TREASURE project. Raised in a tradit...
