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...

Quantifies the effects of postpartum body weight changes on subsequent reproductive performance of N'Dama cattle managed under traditional husbandry systems in Gambia. Analysis of body weights from 4 months before conception to the month of conception showed that 71 percent of cows were gaining w...

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...

A study was undertaken to determine the effectiveness of a progesterone-releasing intravaginal device (PRID) and prostaglandin F2 alpha (PGF2a) in synchronizing oestrus in N'dama and Bunaji cows and heifers and the fertility following artificial insemination at the synchronized oestrus. A total o...
