Editorial

In the present issue of LRRD, the steps in the research required for the development of beef cattle fattening systems using tropical feed resources are presented. The major emphasis is on the role of “bypass” protein as the critical component when using these feed resources, that determines the overall efficiency of production in cattle fattening systems.

The information should serve as a guide and also an encouragement to researchers in the tropics planning and executing their research.
