In the state of Maranhão, this activity has regional relevance, with strong dependence on extensive production systems and the operation of slaughterhouses supervised by the Municipal Inspection Service (SIM), which are responsible for supplying the local market. Therefore, this study aimed to analyze the beef production process and the commercialization structure in a slaughterhouse under municipal inspection in São Luís, Maranhão, Brazil. The research was characterized as descriptive, observational, and quantitative, carried out through on-site monitoring of the slaughter routine from October 22 to November 14, 2025. The slaughtering stages, the profile and origin of slaughtered animals, hot carcass weights, and commercialization models adopted by the agents involved in the production chain were evaluated. During the study period, 717 cattle were slaughtered, with a predominance of females, mainly heifers and cull cows, originating from different municipalities in Maranhão, especially from the Médio Mearim region. Hot carcass weights ranged from 170 to 300 kg, with an average of approximately 235 kg, resulting in an estimated production of 168.5 tons of beef. Commercialization mainly occurred as whole carcasses, forequarters, and hindquarters, with price differences associated with anatomical and functional characteristics of the carcass. It is concluded that the studied slaughterhouse plays a strategic role in local food supply and food safety; however, logistical, structural, and productive challenges remain, highlighting the need for improvements to increase efficiency and sustainability in the beef production chain.

As an ingredient in animal feed, it has attracted interest due to its high nutritional value, availability in various producing regions, and the possibility of utilizing agro-industrial waste, promoting sustainability and reducing costs in animal production. Peanut production generates waste such as: the shell, used for energy generation; the skin and shriveled kernels, used for oil production; and mineral and vegetable residues from the crop, which are sent to landfills. Co-products are residues obtained from agro-industrial processes (alcohol production, fruit juices, grains, crops, and human food) and, because they have adequate nutritional value to meet animal requirements, can be used in diet formulations, replacing part of the corn and soybean meal in animal feed. This study aimed to evaluate the chemical composition of peanuts and their co-products (shell, skin, kernel, and whole peanuts) for their use in animal nutrition. Laboratory analyses demonstrated that the husk has a high content of neutral detergent fiber (NDF = 78.3%) and acid detergent fiber (ADF = 65.5%), with low protein and energy content. The skin stood out for presenting higher levels of crude protein (CP = 23.7%) and ether extract (EE = 27.9%). The grain presented the highest energy density, with 26.1% CP and 46.4% EE, while the whole sample presented intermediate characteristics, balancing energy and fiber (NDF = 58.7%; ADF = 44.2%). It is concluded that peanut by- products can be used in the formulation of animal diets, provided that inclusion limits and sanitary precautions are respected.

Abstact: Brazil has one of the largest buffalo herds in the Western world, with the animals well adapted to Brazilian edaphoclimatic conditions. Buffalo milk has several peculiarities that make it very suitable for the production of dairy products, such as cheese. In this context, the objective was to evaluate the occurrence of enterobacteria in artisanal cheeses made from buffalo milk (Bubalus bubalis), promoting discussion within the scope of the impact on public health. To this end, 20 samples of artisanal cheese from the municipalities of São Bento and Viana, located in the Baixada Maranhense region, were collected and analyzed. In a laboratory setting, analytical units were removed for isolation using standardized microbiological techniques and identification of enterobacteria using a commercial biochemical panel composed of 23 parameters. Enterobacteriaceae were quantified in 100% of the samples, with bacterial populations ranging from 2.4 x 10³ to 5.68 x 2.02 x 10⁷ CFU/g for butter cheese and from 6.7 x 10² to 1.59 x 10⁷ for rennet, and 183 bacterial strains were isolated, identifying 11 different bacterial genera and 18 species of enterobacteria. Among these, Pantoea agglomerans, Proteus mirabilis, Citrobacter freundii, Enterobacter cloacae, and Klebsiella pneumoniae subsp. pneumoniae stand out due to their presence in different environments and their recurrence in human infections. It is concluded that the high percentages of enterobacterial contamination indicate the need to implement appropriate hygiene practices and microbiological quality control measures to ensure the safety of artisanal dairy products, which are suitable to the reality of production, valuing the knowledge of the producers, but without neglecting the safety of the food produced.

Meteorological data from 1991 to 2021 were analysed, obtained from models of the European Centre for Medium-Range Weather Forecasts (ECMWF). Based on this information, the Temperature and Humidity Index (THI) and Black Globe Temperature and Humidity Index (BGTHI) were calculated to characterise the level of thermal stress in two physiological phases: newborns and adults. The results showed that, during most of the year, the average and maximum temperature values exceeded the thermal comfort zone for cattle, and the ITU and ITGU indices indicated a prevalence of moderate to severe heat stress, especially between June and November. These findings show that the climatic environment of Imperatriz poses challenges to maintaining animal thermal comfort, requiring the adoption of management strategies such as shading, ventilation, and constant availability of water to minimise the negative effects of heat on herd performance and welfare.
