Professor Olajide Abraham AMAO obtained his Bachelor of Agriculture (B. Agric.) degree, with specialization in Animal Production from University of Ilorin, Ilorin Kwara State, Nigeria in 1992; Master of Agriculture (M. Agric.) in Animal Reproductive Physiology from University of Agriculture Abeokuta (UNAAB), now Federal University of Agriculture Abeokuta (FUNAAB) between 1995 and 1999; and his doctorate (PhD) degree in Animal Reproduction and Physiology from the University of Ibadan, Ibadan, Nigeria in 2010.
Professor Olajide Amao started his academic career as Graduate Assistant on the 10th October, 1994 and rose through the ranks to become a Professor of Animal Reproductive Physiology on 1st October, 2016. Professor Amao has authored and co-authored several scientific articles published in scholarly journals both locally and internationally. He has also contributed some chapters to some monographs and books.
A profound academic mentor, Professor Amao has successfully supervised and mentored over two hundred (200) Bachelor’s degree project students and several Postgraduate students including Postgraduate Diploma (PGD), Master of Technology (M.Tech.) as well as Doctoral (PhD) students. He is also currently supervising many students, both undergraduate and postgraduate.
Professor Amao’s research focus and current research activities are on the following:
- Mitigating the adverse effects of various environmental and nutritional factors affecting the physiological indices and reproductive efficiency of male non-ruminants.
- Harnessing indigenous goats for dairy potential development.
- Improving the performance of African Giant Snail in captivity.
- The use of biotechnological methods to ameliorate the deleterious effects of gossypol in cottonseed cake on the physiological and reproductive characteristics of non-ruminant animals, especially the male.
- Potentials of Baobab (Adansonia digitata Linn) products in improving the reproductive efficiency of farm animals.
- Exploring the potentials of natural and synthetic antioxidant sources to improve reproductive characteristics of male domesticated animals.
- Mitigating the adverse effects of heat stress on the physiological indices and reproductive efficiency of male non-ruminants using natural sources of antioxidants
Professor Olajide Amao has benefited from a couple of awards and grants including Federal Government Postgraduate Scholarship Award, 1997, UNAAB Abeokuta, Nigeria; University Senate Research Grant, Ladoke Akintola University of Technology, Ogbomoso (Grant for a collaborative research on “Effect of organic turmeric (Curcuma longa) on selected physiological characteristics of rabbits chronically irradiated with ultraviolet radiation – 2012/2013); and TETFUND Conference Travel Grants, 2017, Annual Multidisciplinary Academic Conference held at Harvard Medical School, Boston, Massachusetts, USA.
Professor Olajide Abraham Amao is a Registered Animal Scientist (RAS) as well as member of several professional bodies. He has attended and presented scientific papers at several local and international conferences, seminars and workshops including one of the largest gatherings of Animal Scientists in the world, The Joint Annual Meeting of American Dairy Science Association (ADSA) and American Society for Animal Science (ASAS) held in Orlando, Florida USA in 2015; and The Annual Multidisciplinary Academic Conference held at Harvard Medical School, Boston, Massachusetts USA in, 2017. Conference attendance has also taken him to other parts of the world. He is External Examiner for Undergraduate project students at Federal University of Agriculture, Abeokuta (FUNAAB), Nigeria; Master’s Degree Dissertations and Ph.D Theses at the University of Ibadan, Ibadan, Nigeria; University of Ilorin, Ilorin, Nigeria; Federal University of Agriculture, Abeokuta (FUNAAB); Obafemi Awolowo University, (OAU) Ile-Ife, Nigeria and Federal University of Technology, Akure, Nigeria.
