From biological data collected between January 1986 and December 1989, and economic data collected during 1988, 10-year projections of herd structure, production, and economic and financial returns were calculated for 13 village cattle herds at two village sites in the Gambia. The analyses indica...

Location performance of N’Dama cattle was recorded under village management conditions in four ecological variable villages in the Gambia. A total of 636 cows were recorded during the study. The highest daily milk offtake 1.7 kg/cow/day took place when cows were 4 – 6 weeks post-partum. Daily mil...

The experiments took place in the villages of Pirang (low trypanosomiasis risk), Keneba and Nioro Jattaba (low-to-medium trypanosomiasis risk). In Nioro Jattaba, cows milked once a day while in the other two villages cows milked twice a day. In Pirang and Keneba, 45 calves taken from each village...

Rapid population growth (from 498 million in 1990 to 1.2 billion by 2025) and urbanization (from 2.7:1 to 5.1 rural to urban) in sub-Saharan Africa will profoundly influence the demand for food including milk and other dairy products. Since West Africa accounts for over 42 percent of SSA populati...
