successfully in captivity, yet animal nutrition is a new and relatively unexplored field. Part of the problem is a lack of facilities in zoological institutions and a lack of expertise. There is, thus, a strong need to develop nutritional studies and departments in zoological institutions. Research on nutrition is carried out both as a problem-solving exercise (in relation to ill-health or .
