- Pork meat consumption: a comparative analysis between Brazilian and Portuguese consumersPublication . Fernandes, António; Morais, Juan de Oliveira; Ribeiro, Maria IsabelThis quantitative and cross-sectional study aimed to analyze the trend in pork consumption among Portuguese and Brazilian households, to identify which attributes were most valued by consumers when purchasing fresh pork meat, and to verify whether there were significant differences between Portuguese and Brazilian consumers regarding the factors/motivations for pork meat consumption. The data collection took place between April 16 and June 16, 2024, using a questionnaire through Google Forms. Later, data were analyzed using statistical software appropriate to the Human and Social Sciences. The Chi-square test was used to compare proportions, and the Mann-Whitney test was used to compare two independent groups. Of the 210 valid responses gathered, most consumers were female, students, single, with higher education, living in households of 1 to 3 members with a net monthly income of up to 2,400 euros (R$14,391.89). A few consumers did not consume pork meat (7.6%). Of those who consumed it (n = 194), the majority preferred to buy fresh meat, valuing attributes such as flavor, taste (preference over other meats), and aroma. In the last six months, the frequency of consumption was similar between Portuguese and Brazilian consumers (p-value > 0.05). Furthermore, consumers would prefer the proportion of lean meat to be greater than the proportion of fatty meat. Considering the nationality, animal welfare, local production, organic production, meat tenderness, and low environmental impact were identified as differentiating factors (p-value < 0.05) of pork meat consumption. These factors prove to be more critical for Portuguese consumers than Brazilian ones.
- Portuguese consumers' preference regarding three protected designation of origin transmontano goatling butcher piecesPublication . Fernandes, António; Sousa, Fernando; Aveiro, Dina; Ribeiro, Maria IsabelEach half carcass was divided into three pieces: a leg, a shoulder, and a rib. So, to identify consumers' preferences about the three cuts, a questionnaire was applied at the National Agricultural Fair between June 3 and 11, 2023, in Santarém, Portugal. The sample was composed of 118 consumers aged between 20 and 81 years. Later, descriptive statistics and the Friedman test were used to analyze the data. The majority of the consumers were between 25 and 64 years old (72.9%), male (69.5%), had secondary (25.4%) or higher (36.4%) education, lived in households of two (40.7%) or three people (23.7%) with a monthly net income between 1,001 and 3,000 (44.9%) or 3,001 and 5,000 euros (21.2%) and lived in the districts of Santarém (30.5%), Lisbon (15.3%) and Leiria (11.0%). The frequency of goatling meat consumption is very diverse. In fact, 31.4% said they eat it sporadically, 31.4% more than once a week, 25.4% once a month, and 11.9% one to four times a month. When asked about the likelihood of buying the different cuts, 86.5% of respondents said it was likely or very likely that they would buy the rib, 80.6% the leg, and 79.6% the shoulder. No differences were found in the purchase probability between the leg and shoulder (p-value = 0.879). Still, a preference for the rib was confirmed (p-value < 0.05). The leg, the rib, and the shoulder can be sold between 13.09 and 22.41 euros/kg, 12.92 and 22.96 euros/kg, and 13,66 and 23,64 euros/Kg, respectively.
- Smart Small Ruminant Device: An IoT-Based System for Real-Time Monitoring and Management of Sheep and Goat MobilityPublication . Araujo, Mateus; Castro, José; Castro, Marina; Leitão, Paulo; Bernuy, MiguelThe traditional agricultural practice of silvopastoralism, combining cultural heritage and ecological management, plays a vital role in food production and landscape management. This article explores the integration of precision livestock farming (PLF) into silvopastoral landscapes, using Internet of Things (IoT) technologies for monitoring and data transmission. Commercially available tracking devices lack interesting ergonomics, price and autonomy, and most companies do not focus on goats and sheep. A customized IoT device was developed and tested on goats, employing temperature/humidity sensors, relative position, geolocation and a longrange communication module. The system architecture enabled real-time data flow through the sensing, service and interface layers, resulting in data visualization. The results demonstrate the high reliability, low cost, interesting autonomy and appropriate ergonomics of the device, with the animals exhibiting normal behavior during the tests. The study highlights the effectiveness of IoT-enabled PLF for understanding grazing dynamics and animal behavior in silvopastoral systems, highlighting its potential for sustainable landscape management and the welfare of goats and sheep.
