Autoria: FREITAS, A. C. R. de; ALMEIDA, R. G. de; MACEDO, M. C. M.; GOMES, R. da C.; BUNGENSTAB, D. J.; LAURA, V. A.; OLIVEIRA, C. C. de; GOMES, E. G.; PORFIRIO-DA-SILVA, V.; ALVES, B. J. R.; MADARI, B. E. Conteúdo: Prediction of soil organic carbon (SOC) stocks, tree carbon stocks, enteric emissions, and beef production is essential for evaluating low-carbon livestock systems. However, there is still limited information regarding the use of mechanistic models capable of simultaneously integrating these components under tropical integrated production systems. This study evaluated the performance of the Manure-DeNitrification-DeComposition (Manure-DNDC) model to simulate SOC stocks and estimate the emission intensity of beef production in integrated crop-livestock-forest (ICLF) systems of the Brazilian Cerrado. Methods: Experimental data collected from 2008 to 2016 at the Embrapa Beef Cattle experimental site in Campo Grande, Mato Grosso do Sul, Brazil, were used to evaluate native vegetation (NV), integrated crop-livestock (ICL), and integrated crop-livestock-forest systems (ICLF14 and ICLF22). The Manure-DNDC model was applied to simulate SOC dynamics, beef production, and enteric emissions, and model estimates were compared with measured field data. Results: The model showed good agreement between simulated and measured SOC stocks, beef production, and enteric emissions across the evaluated systems. Annual additional SOC stocks were estimated at -0.025 Mg CO2e ha-¹ year-¹ for NV, +1.06 Mg CO2e ha−¹ year-¹ for ICL, +0.83 Mg CO2e ha-¹ year-¹ for ICLF22, and +0.30 Mg CO2e ha-¹ year-¹ for ICLF14. Emission intensity was estimated at 7.7 kg CO2e kg-¹ live weight gain (LWG) for ICL, whereas negative net values were observed for ICLF22 (-31.5 kg CO22 kg-¹ LWG) and ICLF14 (-69.5 kg CO2e kg-¹ LWG).Discussion: The Manure-DNDC model satisfactorily represented greenhouse gas (GHG) emissions and carbon sequestration under Brazilian Cerrado conditions. The findings highlight the potential of ICLF systems to mitigate GHG emissions and reduce the carbon footprint of beef production. 2026-01-01T00:00:00Z https://www.alice.cnptia.embrapa.br/alice/handle/doc/1174672 Título: Perfil sensorial de análogo de hambúrguer vegetal à base de coprodutos de babaçu e proteínas vegetais. Autoria: SANTOS, V. S. DO A.; SOUSA, P. H. M. DE; NUNES, G. M. V. C.; BENEVIDES, S. D. Conteúdo: A crescente preocupação com o impacto ambiental e a busca por alternativas alimentares sustentáveis têm impulsionado o desenvolvimento de produtos plant-based. Este estudo objetivou elaborar hambúrgueres vegetais utilizando resíduos de coco babaçu e outros ingredientes regionais, explorando seu perfil sensorial e aceitação. Quatro formulações foram desenvolvidas com diferentes proporções de fibra de coco babaçu e óleo de coco. Os hambúrgueres foram avaliados por análises sensoriais, incluindo os métodos Check-All-That-Apply (CATA) e Rate-All-That-Apply (RATA), e submetidos a testes de aceitação e intenção de compra. Os resultados demonstraram que a coloração e o sabor foram significativamente influenciados pelas proporções de fibra e óleo de coco. A formulação com maior teor de óleo (15F25G) foi associada a atributos como "maciez" e "suculência", enquanto a formulação com maior teor de fibra (35F5G) apresentou características mais densas e fibrosas. O "aroma de coco" foi unanimemente identificado e bem aceito em todas as formulações. O "sabor picante" destacou-se em formulações intermediárias, como 20F20G e 30F10G, indicando o impacto positivo do equilíbrio entre fibra e óleo de coco nos atributos sensoriais. A análise de intenção de compra revelou maior preferência pelas formulações 35F5G e 15F25G, sugerindo que tanto a textura firme quanto a maciez podem atrair diferentes perfis de consumidores. Conclui-se que o aproveitamento de resíduos de coco babaçu em hambúrgueres vegetais não apenas promove inovação e sustentabilidade, mas também atende às expectativas sensoriais e de mercado, demonstrando seu potencial para fortalecer a economia circular e valorizar recursos regionais. 2025-01-01T00:00:00Z https://www.alice.cnptia.embrapa.br/alice/handle/doc/1171280 Título: Dehydrated cashew apple in different grinding sizes to sheep. Autoria: ARAÚJO, A. R.; COSTA, J. B.; ROGERIO, M. C. P.; CARNEIRO, M. do S. de S.; MUNIZ, L. C. M.; FONTENELE, R. M.; SILVA, W. L. Conteúdo: The cashew pseudo fruit can be used to animal feeding in tropical and subtropical countries as Brazil, Ivory Coast and Vietnam. Thus, our objective was to evaluate the intake, digestibility of nutrients and nitrogen balance of dehydrated cashew apple by-product to sheep. The experiment was carried out with 24 sheep in a completely randomized design with the treatments distributed in a 4 x 2 factorial scheme to test the inclusion (11, 21, 28 and 33% dry matter basis) and the grinding sizes (3 and 19 mm diameter) of dehydrated cashew apple by-product. To grinding sizes there was no effect to intake and digestibility, suggesting the use of dehydrated cashew apple by-product either finely or coarsely milled. The inclusion up to 33% of dehydrated cashew apple by-product inclusion did not affect voluntary intake and nitrogen balance. However, when including above 21%, there was a reduction of ether extract digestibility and more than 28% reduced dry matter and organic matter digestibility. 2022-01-01T00:00:00Z https://www.alice.cnptia.embrapa.br/alice/handle/doc/1164247 Título: Diversity of phytophagous stink bugs (Hemiptera: Pentatomidae) associated with rice crop in Itapecuru-Mirim, Maranhão, Brazil. Autoria: LIMA, M. H. F.; MELO NETO, A. J. de; PEREIRA, F. A. de S.; CARDOSO, P. L. E. R.; SANTIAGO, C. M.; ABREU, G. B.; SOUZA, J. R. de Conteúdo: From the diversity of phytophagous stink bugs found in rice fields in Itapecuru-Mirim, Maranhão, we have the first record of Edessa meditabunda in the crop, and the second record in Brazil of Paratibraca dubia. Additionally, Tibraca limbativentris, Oebalus poecilus, and Oebalus ypsilongriseus were observed. 2024-01-01T00:00:00Z
