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

"Diagnóstico bioclimático para a criação de ovinos no município de Pedreiras-MA"

Título: "Diagnóstico bioclimático para a criação de ovinos no município de Pedreiras-MA" Abstact: Sheep farming is highly valued in the Northeast region. Sheep farming is of great socioeconomic importance in Maranhão, and this crop still has a lot of room to grow, especially with the help of technology to expand throughout the municipality and state. Thus, defining production models that promote higher weight gain rates for offspring, shorter calving intervals and service periods, represents a basic pillar for the development and growth of sheep farming as a successful agribusiness (CUNHA et al., 2005). Bioclimatic diagnosis involves the analysis of climate data, such as temperature and air humidity, collected over several years. These data are compared with the thermal comfort values recommended for a specific animal species, in addition to bioclimatic indices such as the THI (Temperature and Humidity Index). This process allows us to identify the months and periods of the year in which the animals are or are not in comfortable conditions, according to the climatic variations in sheep farming. Thermal comfort is one of the main management practices that must be adopted in livestock farming to ensure high production and animal welfare

Raças crioulas criadas em comunidades tradicionais do Parque Nacional dos Lençóis Maranhenses

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
