Abiodun Emmanuel Adeyeye (Ph.D, RAS) is a doctoral degree holder in the field of monogastric animal nutrition with many years of experience. He teaches courses such as Monogastric Animal Nutrition, Feed Mill Design and Management, Commercial Feed Mixtures and Premix Production, Introductory Agricultural Biochemistry, Monogastric Animal Production Techniques, Feed Technology, Organic Animal Nutrition, Computer Application in Animal Agriculture, Micro livestock Nutrition at the undergraduate level and Poultry Nutrition, Rabbit Nutrition, Commercial Feed production and Quality, Advance in Rabbit Nutrition, Poultry Feed and Feeding, at the post graduate level. His research focus has been majorly on the use of phytogenic feed additives (Thyme, Oregano, Rosemary, Lemon grass, Sweet orange peels) as a sustainable replacement for antibiotics. Over the years he has worked on alternative feed stuffs such as shrimp waste meal as a substitute for fish meal or soybean meal in broiler chickens and exotic turkeys. Also, Date residues as a replacement for maize in the diets of poultry and rabbits, palm press fibre substituting wheat offal in the diets of growing rabbits.
His current research is on Oregano (Origanum vulgare) essential oil for improved growth performance and gut modulation in broiler chickens, growing and pregnant pigs. His researches on the use of phytogenic feed additives won the Institutional based Research (IBR) grant by TETFUND (Tertiary Education Trust Fund) grant in 2022, 2024 as Principal and co-investigator and research on the use of alternative feedstuff won the TETFUND grant in 2021 as co-investigator.
Dr Adeyeye has supervised forty eight students at the undergraduate level and over twelve students at postgraduate level as major and co-supervisors. He has thirty one journal articles and referred conference proceedings to his credit. He is a member of some professional bodies such as Nigerian Society for Animal Production, Animal Science Association of Nigeria and Nigerian Institute of Animal Science.
