Conservation Agriculture (CA) is being advocated to enhance soil health and sustain long term crop productivity in the developing world. One of CA's key principles is the maintenance of soil cover often by retaining a proportion of crop residues on the field as mulch. Yet smallholder crop–livesto...

The production performance of indigenous goats under sedentary and transhumant management systems in Sudan, Mali and Kenya are investigated. Age at first parturition was 15.5 months in Mali but was delayed to 18 months in Kenya where management was better. Kidding intervals were 7.8, 10.6 and 9 m...

Background
The impacts of vaccination on the transmission of Rift Valley fever virus (RVFV) have not been evaluated. We have developed a RVFV transmission model comprising two hosts—cattle as a separate host and sheep and goats as one combined host (herein after referred to as sheep)—and two vec...
