Professor | UNIVASF | Brazil
Dr. Cleyton de Almeida Araújo is a distinguished researcher and academic specializing in Animal Science, with an emphasis on ruminant nutrition, forage management, and sustainable livestock production systems. His research primarily focuses on optimizing feed efficiency, improving forage quality, and developing eco-friendly livestock management practices that reduce greenhouse gas emissions while enhancing animal productivity in semiarid regions. As an Adjunct Professor at the Federal University of the São Francisco Valley (UNIVASF), he plays a vital role in advancing experimental studies on silage fermentation, mineral balance in animal nutrition, and biosaline agriculture. Over the years, Dr. Araújo has authored numerous scientific articles in high-impact journals, contributing significantly to understanding forage preservation, carbohydrate fractionation, and the nutritional dynamics of alternative feed resources such as cactus pear and cassava shoots. His collaborative works have also examined the interplay between animal nutrition and environmental sustainability, highlighting innovative strategies for resource-limited ecosystems. Beyond his academic achievements, he has contributed to the scientific community through applied research that supports livestock farmers and policymakers in developing climate-resilient agricultural systems. His findings on feed substitution and silage improvement have practical implications for animal welfare, soil health, and rural livelihoods. Dr. Araújo’s scientific vision is rooted in bridging advanced nutritional science with sustainable production methods, fostering innovations that balance productivity with environmental stewardship. Through his continued research and mentorship, he aims to strengthen the resilience of tropical livestock systems, contributing to global efforts in food security, ecological conservation, and rural development.
