Outlines past attempts to develop a base of raw materials for the textile industry from indigenous animals in Mali. Describes notable efforts to upgrade local Macina sheep for increased wool production by selection or cross-breeding with Merinos, increasing goat wool production by crossing import...

Results of a 2-year study on goats and sheep in northern Burkina Faso are reported. In both goats and sheep, females comprised more than 75% of flock numbers. Intervals between parturitions in goats were 312 days overall but were significantly affected by the season of the previous birth: in shee...

Summarizes a baseline study of the traditional livestock production system of central Mali, classifying production systems in the study in the study zone according to the degree of dependence on livestock products for gross revenue or food supply of the household or production unit, and according...
The result of an intensive 15 months study of 10 flocks of indigenous sheep is recorded. Lambing rates approach 1.5 lambs per ewe per year, but a death rate of 23 percent and on off take of 27 per cent, means that flock numbers are probably slightly declining. Twins account for 14 per cent of all...

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...
