Prof. Leonard Nnabuenyi Agwunobi

Professor
Animal Science
agwunobi@unical.edu.ng

I am a Professor of Animal Nutrition. I have an interest in research and community service. I have done some research works in the use of cassava peels, an agro. by-product of cassava flour in poultry production; in the use of novel feedstuffs, the nut of nypa palm, in poultry production; determined the protein and energy requirements of guineafowls and also protein and energy requirements of grass cutter.
