The concept of on-farm adaptive research in the development of livestock production in Nigeria por Little, D.A.

“…In the context of sub-Saharan Africa, it is well recognized that approaches to addressing these needs based on the transfer of established technologies from the industrialized world have been singularly unsuccessful. Many reasons have been advanced for this, which might be distilled into an overriding principle that the bases upon which the transferred technologies were developed were inappropriate for the systems to which transfer was attempted. …”
