Prof. Emmanuel K. Adu
Research Scientist

Office: ARI Room 20


Degrees: PhD. (UG, Ghana), MAppSci. (Massey University, New Zealand),
BSc. (Hons). (UCC, Ghana), DipEd. (UCC, Ghana)


Research Interests
  • Nutritional effects on fetal health
  • Development of agribusiness incubation models
  • Industrial applications of research outputs, e.g. development of industrially applicable products from eggs, snails, pig skin, fish scales and cow hide

  • Current Research
    I am currently researching into reducing reproductive wastage in domesticated livestock species using the grasscutter as a model. During the course of fetal development in the grasscutter, about 40% of all implanted embryos are resorbed and this is believed to be as a result of nutritional imbalances. The aim of the research is therefore, to determine the right nutritional balance that support optimum fetal growth thereby resulting into increased reproductive output. I am also researching into developing various agribusiness incubation models that would help translate various research outputs into business ventures. Currently, with support from KOPIA, we are looking at developing small-scale poultry production models into viable businesses. Other research interests are in the development of new products from poultry and livestock species. In this regards we are looking at optimizing our locally developed techniques for the production of egg powder for the bakeries and confectionaries, powdered albumin for development of various industrial products and the production of gelatin from pig skin, snails and fish scales.

    Current Projects
    An Assessment of the access and adoption of Climate Smart Agricultural Technologies on the livelihood of gender in crop-livestock systems in northern Ghana. This is a PhD research working title.


    E. K. Adu (PhD) is the immediate past Director of the CSIR-Animal Research Institute, a Professor at the CSIR College of Science and Technology (CCST), and an Adjunct Professor at the Department of Animal Science, University of Ghana, where he developed and teaches a course in Micro-livestock Production. He is also the founding Chief Executive Officer of CCLEAr Agribusiness Incubator, which is a FARA-supported initiative in Ghana. Prof. Adu holds a B. Sc. (Hons) Zoology and a Dip.Ed both from the University of Cape Coast, an M. App. Sci. (Animal Science option) from Massey University, New Zealand and a Ph.D in Animal Reproductive Physiology (nutritional effects on fetal health) from University of Ghana, Ghana. He has training in animal nutrition, reproductive physiology and grazing management. Determination of nutritional requirements of livestock, nutritional effects on fetal survival, deer production from pasture, grazing management, molecular and cellular concepts, and application in reproduction, molecular and immunoassay applications in laboratory diagnostics. Prof. Adu has over 25 years research experience in grasscutter farming; and has significantly contributed to backstopping most Grasscutter Farmers’ Associations across the country. His research efforts have resulted in 32 publications as books, book chapters and peer-reviewed journal articles. As the Director of the CSIR-Animal Research Institute, Prof. E. K. Adu led a team to locally adapt the technology for producing egg powder, powdered albumen and egg yolk oil. Among other things, he is also leading the research into developing locally adapted techniques for the production of new products from snails, pig skin, fish scales and cow hide. [Under his leadership at CCLEAr Prof. Adu has helped to commercialize four (4) technologies, trained over 2,000 smallholder farmers in pig production, about 300 youth in grasscutter agribusiness ventures, and incubated 200 of them. Prof. Adu has also mentored and coached over 100 young interns who are ready to take up opportunities in the job market, and has helped to create over 1,500 direct and indirect jobs of which a significant percent is for women. He has also helped build a marketing network for about 200 SMEs. Prof. Adu has managed to enlist 16 tertiary institutions, one (1) research institute, and two (2) private sector players to support the consortia in research and churn out technologies for commercialization, mentor raw talent and implement the revamped agribusiness curriculum. Besides the above, the incubator has reached out to more than 3,000 livestock entrepreneurs whose livelihoods have been impacted by the programme.
