The Tropical Agriculturalist series

Livestock product/on systems examines how individual species of domestic livestock can be integrated into the whole concept of sustainable agriculture in the tropics. The main part of the book is devoted to a series of case studies covering most, if not all, of the systems of livestock husbandry used in the tropics. The reasons why these systems have been developed are outlined, their limitations highlighted and the ways in which they could be improved are discussed. This part of the book is a useful short reference work presenting the main features of the extremely varied livestock production systems found across the tropics.

Readers of the book will obtain a good insight into how livestock and crop husbandry can be linked in the wetter regions of the tropics to improve the use of resources. In the dry regions of the tropics, where crop husbandry is not an option, animal husbandry is the best way of utilizing these regions for the benefit of people. The book shows how livestock are essential for the development of ecologically sound systems of food production. All types of livestock are covered including buffalo, camels and poultry.
