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...

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...

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...
Presents results of a study carried out in The Gambia on birth-weight data recorded between 1986 and 1991 on 3453 N'Dama calves from the village production systems to identify major factors influencing this trait and to quantify the relationship between birth weight and early calf mortality. Leas...
