He proceeded to the University of Ibadan in 1975. He stayed at the University of Ibadan for 8 years during which by divine grace and hard work he obtained the degrees of B.Sc. Agric. Biochemistry and Nutrition, Second Class (Honours) – Upper Division in 1978, M.Sc. Animal Science (Agricultural Biochemistry and Nutrition) in 1980 and Ph.D. (Animal Science) Agricultural Biochemistry and Nutrition in 1983. Prof. Onwuka is an accomplished academic and researcher who started his working life as a Teacher at St. Columbus’ Grammar School, Agbor between 1973 and 75. He had a brief stint at United Bank for Africa, (UBA) Ltd. Benin‑City in 1975. On graduation from Ibadan in 1978, He was posted to the Nigerian Livestock and Meat Authority – Poultry Production Unit, Ilorin for the mandatory National Service (NYSC) between 1978 and 1979. His love for teaching made him also help out at Government Secondary School, Ilorin during the same period. He took up an appointment as Agric Officer II Ministry of Agriculture and Natural Resources, Benin‑City in the old Bendel State. His stay was very brief as he was back at Ibadan the same year for his Postgraduate studies.
