Item Acesso aberto (Open Access) Avaliação da qualidade do Mapará (Hypophthalmus spp.) estocado entre camadas de gelo provenientes dos mercados de pescados de Santarém – PA(Universidade Federal do Pará, 2021-08-09) CARDOSO, Renata Lima Sabá; CUNHA, Edinaldo José de Sousa; http://lattes.cnpq.br/8714515962963079Maintaining the good quality of fish is essential for consumer health and for strengthening the fish production chain. One of the main ways to maintain this quality is through the use of ice for fish storage. Thus, this research aimed to identify, through sensory, microbiological and chemical analyzes (H2S, ammonia and pH tests) factors that offered variation in the shelf life of the Mapará (Hypophtalmus spp.) ice layer storage process. Two collections were carried out at the Mercado do Pescado fair in Santarém-PA: experiment 1, with 143 fish and experiment 2, with 81 fish. For the analyses, two fish were removed for sensory evaluation, two for pH evaluation, one fish for ammonia test, one for the H2S Eber test and one fish for microbiological analysis. The results obtained in the sensory analysis indicated that the fish rejection point occurred between the 17th and 20th day. In experiments 1 and 2, the pH values in fish meat were above 6.5, that is, outside the limit established by law. In the Éber test for H2S, there were positive results from the 11th day. The Éber test for ammonia showed a positive value from the 14th day on. In the microbiological analysis, NMP/g values of <1.8 to 79x104 (NMP/g) were found for thermotolerant coliforms and from 11 to >1,600 (NMP/g) for total coliforms. Ice storage for Hypophthalmus spp. proved ineffective for long periods. The result allows us to infer that monitoring, research and continuous awareness of good fishing practices and post-harvest fish management are necessary.Item Acesso aberto (Open Access) Sistema semiautomatizado para redução do desperdício de ração e otimização do conforto térmico no processo de criação avícola de pequenos produtores do interior da região Amazônica(Universidade Federal do Pará, 2021-08-02) BEZERRA, Rômulo Cavalcante; NASCIMENTO, Manoel Henrique Reis; http://lattes.cnpq.br/0850846128967798In the Amazon region, the reality of the conventional laying poultry production chain consists of farms with structures that are inferior to those in other regions, with a massive presence of small poultry farmers, without a water, food and air conditioning automation system. The need for improvements in the poultry process that the small producer needs to produce can be linked to the relationship of implementing technology for monitoring equipment or systems. Therefore, the motivation of this study was the creation of a semi-automated system to optimize the thermal comfort of birds and red3uce feed waste in the laying poultry production process for small producers in the interior of the Amazon region in order to reduce mortality and maximize the profit. The methodology designated for the construction of this research was based on the nature of applied research, with a view to the qualitative-quantitative approach, through technical procedures of a case study. After assembly of the semi-automated system for feeding, adding the total savings for feed consumption would be 1964.20 kg of feed, in reais it would be R$ 7,856.80. And for the ambiance system, we have savings on the energy bill of 60.94 reais a month and 731.31 reais a year. The semi-automated systems suggested for small poultry farmers in the Amazon region theoretically fulfill their objective, both for the improvement of waste and for the provision of animal welfare and increased profitability.
