  • Current Research

    The focus of my current research is on identifying the most promising forages in the Coastal Savannah zone of Ghana, in terms of availability and acceptability to rabbits, and determine the ideal inclusion levels of the forages in composite diets that will enhance the general performance and health of rabbits. Ghana abounds with forages, comprising tree leaves, forbs, shrubs and graminoids, most of which are not used for human consumption and available as animal feed for most part of the year. However, most rabbit keepers are compelled to feed their animals on expensive poultry feed, a practice that impedes the productivity of the animals and renders rabbit keeping unattractive to the farmers. Provision of appropriate information regarding the nutrient quality of indigenous forages, the appropriate inclusion levels in diets and their effect on growth performance, meat quality and health of rabbits will lead to production of good quality feed at lower cost thereby making rabbit farming profitable.
