Research Interests
  • Utilization of agro-industrial by-products as feed resources for monogastric farm animals.
  • Application of feed additives in non-ruminant diets.
  • Determination of nutritional requirements of non-ruminants

  • Current Research
    Provision of cheap but good quality feed remains one of the major focus of scientists and farmers in the pig production value chain. Alternative sources of feed have to be explored for feeding pigs. In recent years, attention has been focused on the use of agro-industrial by-products (AIBPs) as non-conventional feed resources for feeding pigs in the tropics. Some of these by-products are readily available at production sites. These are not utilized by humans therefore; their usage will tend to reduce the cost of feeding and eventually reduce the pollution hazard to the environment. Several AIBPs have been considered as feed resources in the feeding of livestock. Nevertheless, there are other potential ones which have not been adequately studied and exploited. Some of the main ones are by-products of the cocoa industry which include cocoa pod husk, cocoa bean shell, cocoa bean meal and cocoa placenta. Ghana is a major producer and exporter of cocoa beans in the world, therefore large quantities of cocoa by-products are thereby produced which invariably go waste on farms. Optimizing the use of these by-products in livestock diets will reduce the cost of feeding.


    Mr. Kwame Owusu Amoah is a Senior Research Scientist of the Council for Scientific and Industrial Research-Animal Research Institute (CSIR-ARI). He obtained a Master of Science degree (M. Sc.) in Animal Nutrition from the Kwame Nkrumah University of Science and Technology, Kumasi, Ghana and is currently pursuing doctoral degree with his alma mater. His area of specialization is animal nutrition, specifically monogastric livestock and poultry nutrition. His research focuses on the utilization of agro-industrial by-products as alternative source of feed resource in the diets of non-ruminant farm animals. He has been involved in training livestock and poultry farmers nationwide at research-extension-farmer linkage and pig farmers’ association workshops. Since his employment, he has been actively engaged in several donor-funded projects and consultancies among which are the West Africa Agricultural Productivity Programme (WAAPP), the Brazilian Agricultural Research Corporation (EMBRAPA), Food and Drugs Authority (FDA)-Ghana, Creating competitive entrepreneurs in the pig value chain through the Skills Development Fund. He has seventeen publications in peer-reviewed journals, training manual, etc.
