Título: Central de inteligência em saúde suína: uma nova era na vigilância e análise de risco das doenças suínas no Brasil. Autoria: ZANELLA, J. R. C.; NICOLINO, R.; BENELLI, D. A.; AMARAL, A. L. do; PEREIRA, M. L.; MORES, M. A. Z.; TREVISAN, G.; SILVA, G.; CEZAR, G.; LINHARES, D. C. Conteúdo: A suinocultura brasileira enfrenta desafios crescentes frente a doenças infecciosas que impactam diretamente a produtividade, rentabilidade e a saúde pública. A criação da Central de Inteligência em Saúde Suína (CISS) representa um marco inovador para a vigilância, análise de risco e comunicação de diagnósticos sanitários no Brasil. A CISS articula dados laboratoriais nacionais de forma padronizada, permitindo monitorar a dinâmica de agentes patogênicos endêmicos, suportar decisões de manejo sanitário e fortalecer a resiliência do setor. Esta palestra vai discutir os fundamentos do sistema, sua importância para a saúde animal e pública, os potenciais impactos sobre a produção suína no Brasil e perspectivas futuras.

Título: Nutritional value and prediction of digestible and metabolizable energy of full-fat deactivated soybeans for pigs. Autoria: BERTOL, T. M.; LUDKE, J. V.; COLDEBELLA, A.; RECH, H. Conteúdo: Objective: The objective of this work was to determine the energetic values of 14 full-fat deactivated soybeans samples, the effect of partial removal of the hull, and to develop equations for predicting digestible (DE), metabolizable (ME), and ME corrected for nitrogen balance (MEn) for pigs.Methods: Ten metabolism experiments were conducted over a two-year period to evaluate 14 batches of full-fat deactivated soybeans, following the method of the total collection of feces and urine. One hundred and ninety-two pigs with an average initial body weight of 51.4±5.4 kg were assigned to dietary treatments.Results: Partial dehulling of soybeans did not affect DE, ME, and MEn values. The variables that best explained the variations (p<0.05) in DE were ureatic activity (UA) and crude fiber. The variables that showed the greatest association (p<0.05) with ME and MEn were UA, protein solubility, and processing pressure. The observed effect of UA on energy values was quadratic (p<0.05). Phosphorus also showed association (p<0.05) with DE and ME and the energy applied per kg of sample showed association (p<0.05) with ME and MEn.Conclusion: The overall mean values of DE, ME, and MEn were 4,558, 4,457, and 4,344 kcal/kg, respectively. The partial removal of the hull prior to soy deactivation did not affect the digestibility or the energy values. This study shows that the processing conditions are the main factors affecting the energetic value of full-fat deactivated soybeans for pigs, which can be accurately predicted using a combination of chemical composition, quality indicators, and processing parameters.

Título: Optimized bioethanol production from Lemna minuta biomass harvested from polluted water via acid and enzymatic hydrolysis. Autoria: SCHUTZ, E. R. D.; MIGNONI, D. S. B.; MICHELON, W.; NUNES, E. de O. Conteúdo: ABSTRACT: The contamination of water bodies through domestic, agricultural, and industrial discharges remains a critical environmental challenge, leading to eutrophication and harmful impacts on aquatic ecosystems and public health. In response, phytoremediation, which utilizes aquatic plants for pollutant removal, have gained attention. This study investigates the potential of Lemna minuta biomass, harvested from a polluted pond, for bioethanol production. The research evaluates carbohydrate content and explores the efficiency of acid and enzymatic hydrolysis in converting the biomass into fermentable sugars. The study’s findings reveal that Lemna minuta exhibits a carbohydrate content of 36.46 ± 1.69%. Acid hydrolysis demonstrated a high conversion efficiency, with optimal conditions achieving up to 99.20% efficiency and 18.09 g L−1 total reducing sugars. Enzymatic hydrolysis, while effective, yielded lower efficiencies, indicating the need for further optimization. Fermentation tests using Saccharomyces cerevisiae chardonnay resulted in ethanol production of 1.5 g L−1 , highlighting the potential of Lemna minuta as a sustainable bioethanol feedstock. These findings highlight the potential of Lemna minuta as a sustainable feedstock for bioethanol production while contributing to environmental remediation, reinforcing its dual role in renewable energy and ecosystem restoration.
