Título: Diagnóstico bioclimático para a criação de suínos no município de Pedreiras – MA Abstact: Swine farming plays a significant role in the Brazilian economy, particularly in the South and Southeast regions. However, in the state of Maranhão, it still faces major challenges such as poor infrastructure, low technological adoption, and inadequate management practices. This study aims to analyze the impacts of climatic conditions on pig production in the municipality of Pedreiras (MA), with a focus on animal bioclimatology. The research is based on the collection and analysis of meteorological data (temperature and humidity) and the application of the Temperature-Humidity Index (THI) to assess the thermal comfort of pigs at different development stages. Through the bioclimatic diagnosis, it is possible to propose management strategies to reduce heat stress, improve animal welfare, and enhance productivity. The study also aims to contribute technical information to support public policies and practical actions to strengthen swine farming in the region

Título: Raças crioulas criadas em comunidades tradicionais do Parque Nacional dos Lençóis Maranhenses Abstact: In Brazil, domestic animal breeds developed from Iberian breeds introduced during colonization, which for centuries were subjected to natural selection in different environments, developing adaptive characteristics. In the Lençóis Maranhenses National Park (PNLM), traditional communities survive on plant and animal extraction and, more recently, on local tourism. The objective of the research was to identify, in the traditional communities of the PNLM, the breeding of animals remaining from the colonial period and to describe their racial characteristics. Data collection was carried out in eight traditional communities through interviews with breeders, in addition to visual observation of the animals to record their racial characteristics. To evaluate and discuss the results, the data were subjected to descriptive statistical analysis using the Excel program, using percentage values, figures and tables. The research included a total of 1,533 animals from 10 domestic species raised by families in the communities, with goats being the most significant species (33%), with a total of 507 animals In the morphology of the herds, it was possible to identify phenotypic characteristics (size, size and shape of the ears, head profile, coat color, among others) similar to the characteristics of the locally adapted

Ocorrência de fungos filamentosos e leveduras em queijo artesanal de origem bubalina produzido na Baixada Maranhense

Título: Ocorrência de fungos filamentosos e leveduras em queijo artesanal de origem bubalina produzido na Baixada Maranhense Abstact: Artisanal cheese production is a consolidated cultural tradition that contributes to regional identity and local economic development. In Baixada Maranhense, this activity is essential for the economy of small family producers who use techniques inherited from previous generations and local raw materials. However, these dairy products are highly susceptible to microbiological contamination, which poses a risk to public health and requires attention to ensure the quality and safety of this dairy product. In this sense, the objective of the study was to verify the occurrence of filamentous fungi and yeasts in artisanal cheese of buffalo origin produced in Baixada Maranhense. For this purpose, 20 samples of cheeses produced in the municipalities of São Bento and Viana, both located in Baixada Maranhense, were collected. The cheeses were transported in isothermal boxes to the State University of Maranhão, where the enumeration of filamentous fungi and yeasts was performed and the identification of filamentous fungi through morphological characteristics, both macroscopic (colonial) and microscopic (cellular structures). The results of the study demonstrate the presence of molds and yeasts in 100% (n = 20/20) of the cheese samples evaluated, with fungal populations ranging from 1.9 x 10³ to 1.4 x 107 CFU/gram. Two genera of fungi were identified, Aspergillus sp. and Penicillium sp. It is concluded that there is a high occurrence of filamentous fungi and yeasts in the artisanal cheese samples, with the existence of two microtoxigenic fungal genera, which constitutes a risk to the microbiological safety of consumers and the urgent need to implement good manufacturing practices and public policies to guarantee the quality and safety of this important artisanal product

Ocorrência de enterobactérias em Colossoma macropomum (CUVIER, 1816) criados em sistema intensivo na Ilha do Maranhão: impacto para a sanidade animal e saúde pública?

Título: Ocorrência de enterobactérias em Colossoma macropomum (CUVIER, 1816) criados em sistema intensivo na Ilha do Maranhão: impacto para a sanidade animal e saúde pública? Abstact: Colossoma macropomum (tambaqui) is a species native to the Brazilian Amazon that has good zootechnical performance in intensive farming, constituting the basis of fish farming in Maranhão. However, for good aquaculture production, there is a need to disseminate good nutritional, reproductive and sanitary management practices, the latter including periodic monitoring of the presence of pathogens in water and fish. In this context, the objective of this study was to evaluate the occurrence of enterobacteria in C. macropomum farmed in an intensive production system on Maranhão Island. For this purpose, 40 tambaquis, including males and females, from 10 fish farms on Maranhão Island were captured. In a laboratory environment, muscle fragments were removed from the samples for quantification of total and thermotolerant coliforms, isolation and bacterial identification. The phenotypic identification of enterobacteria was performed using a commercial biochemical panel composed of 23 parameters. Total coliforms and thermotolerant coliforms were quantified in 30% (n = 12/40) and 15% (n = 6/40) of the fish evaluated, respectively, with bacterial populations ranging from 3.6 to ≥ 2,400 MPN/g. Of the 12 samples of C. macropomum contaminated by bacteria from the coliform group, 63 isolates were obtained with the identification of eight distinct species of enterobacteria, distributed as follows: Proteus vulgaris (28.57%); Citrobacter freundii (19.05%); Proteus mirabilis (14.29%); and Escherichia coli (14.29%). Kluyvera ascorbata, Providencia alcalifaciens, Edwardsiella hoshinae and Escherichia hermannii were also identified, but at lower frequencies. It is concluded that the eight species of enterobacteria isolated are indicative of inadequate hygienic-sanitary conditions and represent epidemiological and sanitary risks for the environment, aquatic biodiversity and human health
