Milk production characteristics and productivity of N'Dama cattle kept under village management 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...
