With short cycles and high productive efficiency, it has become strategic for small and medium-scale producers. This study presents the development of spreadsheets in Excel to estimate production costs and perform economic-financial evaluation in broiler farming under a semi-intensive system. The tool was designed to include accounting and zootechnical variables such as fixed and variable costs, revenues, investments, and performance indicators. The spreadsheets allow producers to monitor daily feed consumption, mortality, and weight gain, as well as to project revenues and calculate indicators such as profitability, return on investment, and break-even point. The proposal aims to provide small and medium-scale poultry farmers with a practical and accessible solution to transform scattered data into reliable managerial information, fostering greater production efficiency and economic sustainability Thu, 01 Jan 2026 00:00:00 GMT https://repositorio.uema.br/jspui/handle/123456789/6714 2026-01-01T00:00:00Z https://repositorio.uema.br/jspui/handle/123456789/6688 Título: Microrganismos indicadores higiênico-sanitários em queijo artesanal elaborado a partir de leite de búfala (Bubalus bubalis): importância para o consumo seguro Abstact: The objective was to evaluate the presence of hygienic-sanitary indicator microorganisms in artisanal cheeses made from buffalo milk (Bubalus bubalis), promoting discussion of the importance of consuming safe food. Thus, 20 samples of artisanal cheese produced in the municipalities of São Bento and Viana, located in the Baixada Maranhense region, were collected. In a laboratory setting, analytical units were removed for the enumeration of viable mesophilic and facultative aerobic bacteria and enterobacteria, in addition to the detection of Escherichia coli and Salmonella spp. using traditional and established microbiological techniques. Mesophilic aerobic bacteria were found in all analyzed samples, with bacterial populations ranging from 5.2 x 10⁶ to 5.94 x 10⁷ CFU/gram for butter cheese and from 8.28 x 10⁵ to 1.4 x 10⁸ CFU/gram for curd cheese. Regarding enterobacteria, it was found that 100% of the samples were contaminated 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. Despite the high contamination with enterobacteria, E. coli and Salmonella spp. were not found in any of the samples. It is concluded that all samples analyzed met the minimum requirements for the E. coli and Salmonella spp. parameters established in Brazilian legislation. However, the high microbial load of mesophilic aerobic bacteria and enterobacteria suggests flaws in the production process, including poor quality raw materials, cross-contamination by handlers, contact of raw materials and cheeses with unhygienic surfaces, and inadequate product preservation Sun, 21 Dec 2025 00:00:00 GMT https://repositorio.uema.br/jspui/handle/123456789/6688 2025-12-21T00:00:00Z https://repositorio.uema.br/jspui/handle/123456789/6464 Título: Avaliação das condições de bem-estar em creches de suínos em São Luís-MA Abstact: The present study aimed to evaluate favorable and unfavorable conditions for the welfare of piglets during the nursery phase, identifying the variability of factors related to housing, management, health, and animal behavior in nursery units of intensive swine production systems practiced on the Island of São Luís. The research was conducted through the development and on-site application of questionnaires during visits to ten swine farms between February and August 2025, covering the assessment of facilities (floor type, stocking density, ventilation, and thermal environment), management practices (feeding, water supply, and environmental enrichment), as well as health and behavioral indicators (presence of lesions and occurrence of tail biting). The observed results revealed that the intensive production system in the region presents significant challenges, particularly due to asymmetries in crucial aspects of animal welfare. It was found that 90% of the farms had ground-level flooring, with 70% being concrete and 20% subfloor, while only 10% had suspended slatted floors, with the use of subflooring being predominant (70%). All units had fiber-cement roofing; however, 70% did not have any type of thermal monitoring, only 20% used curtains and 10% used thermometers, indicating deficiencies in the maintenance of thermal comfort, which is especially important in hot climate regions. Furthermore, 50% of the farms operated under excessive stocking density, representing an unfavorable management condition that compromises space availability and animal movement, which, combined with the absence or inadequacy of environmental enrichment in most farms (80%), contributes to increased stress and the development of stereotypic behaviors in animals. It is concluded that the intensive swine production system on the Island of São Luís requires significant improvements regarding animal welfare, including the implementation of more appropriate management practices and facilities that promote adequate thermal and environmental comfort for the animals.

This study aimed to create a bioclimatic diagnosis of the municipality of Amarante do Maranhão (MA) for raising Morada Nova sheep by analyzing annual meteorological data, including air temperature (TA), relative humidity (RH), and thermal comfort indices such as the Temperature-Humidity Index (THI) and the Black Globe Humidity Index (BGHI) to identify periods of thermal comfort and discomfort for the animals. The results demonstrated that the first half of the year presents lower average TA and high RH, while the second half concentrates the most critical conditions. This period shows a gradual increase in TA, a sharp drop in RH, and a higher radiation load, especially between September and November, when the THI and BGHI exceed comfort limits, indicating a significant risk of thermal stress. These conditions directly affect feed intake, respiratory rate, weight gain, reproductive efficiency, and animal welfare. It is concluded that the climate of Amarante do Maranhão imposes relevant challenges on the production of Morada Nova sheep, reinforcing the need for thermal management strategies, such as natural or artificial shading, continuous water availability, adjustments to grazing schedules, and interventions that promote a microclimate more suitable for the performance and sustainability of the activity Tue, 16 Dec 2025 00:00:00 GMT https://repositorio.uema.br/jspui/handle/123456789/6276 2025-12-16T00:00:00Z
