Presents the results of feeding trials in three villages in Gambia, viz, Keneba, Pirang & Nioro Jattaba, conducted to assess responses during the dry season to small inputs of a protein supplement in recently calved cows and in young suckling calves.

N'Dama cattle production in relation to nutritional interventions in villages in The Gambia
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...

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...

Genetic improvement in medium to low input systems of animal production: The West African experience
Two groups of light N'Dama calves were fed different quantities of milk from birth to 10 months of age to compare efficiencies fo converting milk to live-weight gain, and to assess the economic efficiencies of the two feeding regimes. Group one receives an average of 347 kg per calf, with a daily...

An assessment of the biological and economic efficiency in conversion of milk to growth in N'Dama calves
Four experiments were carried out in which supplements of locally available proteinaceous by-products were given to young, mainly pre-weaned calves that ranged in initial weight from 30 to 90 kg. The experiments were part of a programme designed to establish practical and economical nutrition int...
Groups of lactating N'Dama cows maintained under traditional husbandry conditions were given dry season supplements of locally available oil seed residues to establish nutritional recommendations for improving livestock productivity in the sub-humid zone of West Africa. In one experiment cows wer...

Health and production aspects of village based N'Dama cattle in The Gambia
This paper summarises the productivities of N'Dama cattle in traditional production systems inthe Gambia and describes the responses in productivity achieved when nutritional interventions were applied. The studies were carried out at six sites where herd management patterns are similar. Cattle a...
