Abdalla, A.L., an Associate Professor at the University of São Paulo, specializes in Agronomy, Animal Nutrition, and the use of Nuclear Techniques in Mineral Metabolism in Ruminants. With post-doctoral experience from Reading University (UK) and UC-Davis (USA), his research focuses on animal production, feed evaluation, and sustainable ruminant production strategies. Since 1985, he has been a researcher at CENA/USP, specializing in nuclear techniques for agricultural productivity. Abdalla consults for FAPESP, CNPq, and international research foundations, and advises graduate and postdoctoral students at CENA/USP. His recent research has significantly impacted ruminant nutrition and methane mitigation, offering insights into methane emission reduction. He explores predictive modeling for herd management and innovative methods for assessing ruminant nutrition, including the use of purine derivatives and creatinine urine excretion as indicators of sheep feed intake. His work also evaluates sustainable grazing practices and alternative feed supplements for ruminants, highlighting plant-based supplements' potential to enhance livestock feeding without increasing methane production. Additionally, Abdalla investigates the role of integrated crop-livestock-forestry systems in reducing greenhouse gas emissions and promoting sustainability in forage-based livestock systems, emphasizing holistic approaches to address environmental challenges (Source: Lattes Curriculum)

Brazil is one of the world's largest producers and exporters of food, feed, fiber and (bio)fuel. Estimates indicated that the country would need to increase food production in 40% to meet global demands by 2050. Meanwhile, tropical agricultural systems have to be important allies to sequester carbon (C) and reduce greenhouse gases emission, and consequently, contribute to mitigating clima…
In this project, we admit the conception that the recent transformations of the rural world establish a new territorial dynamic, based on the interactions of the forms of organization of producers in the various Alagoas' contexts. This work aims to contribute to studies on rural areas. The object of study is a research on the territory to highlight aspects that distinguishes it in the eco…
At LANA-CENA/USP we will be prospecting enzymes in Brazil and abroad, natural or synthetic, evaluating the fibrolytic activity under rumen conditions (pH 6-7 and temperature 39°C) through laboratory testing already in use in Brazil and the ones proposed from Reading University .After the selection of promising materials, these enzymes will have identified its proteins by proteomic studies…

Silvopastoral Systems (SPS) represent a sustainable approach that integrates ruminants, grasses, shrubs, and trees to mimic forest ecosystems, thereby enhancing carbon capture, ecosystem services, and animal welfare, while promoting sustainable meat/milk production. Additionally, incorporating trees/shrubs into grass-based systems offers nutritional benefits, reduces costs, and manipulate…
The research project aims to assess the in vitro production of enteric methane (CH4) from substrates containing biomass suitable for ruminant grazing, incorporating legumes, tropical macroalgae, and biochar. It seeks to evaluate both short and long-term contributions to CH4 emissions, isotopic compositions, and impact on the rumen microbiome. Experiments will be conducted at LANA-CENA/USP…

The stable isotope technique will be used on in vivo and in vitro studies to determine the Dry Matter (DM) and nutrient intakes and the contribution of forage legumes in the enteric methane (CH4) emitted by ruminants. In experiment 1, two trials will be conducted, one, using Pigeon pea (Cajanus cajan) intercropped with Brachiaria decumbens in degraded or recovered pastures and the another…

The objective of this research internship proposal is to apply multiple modeling approaches to assess the environmental impacts (GHG emissions - CH4, NO2, CO2eq) of beef cattle production in tropical integrated systems to recommend strategies for greenhouse gases mitigation, and to provide subsidies to propose a sustainable and resilient food alternative for beef cattle production; apply …
CCondensed tannins (CT) are a group of secondary phenolic compounds often found in forages, mostly legumes, which presents the ability of affecting some aspects of ruminal fermentation, such as the degradability of dietary nutrients and methane (CH4) production. The concentration of these molecules in diets is not the only parameter related to the occurrence of their effects on the metabo…
