Reviews the results of on-farm experiments conducted to study the effects of milking on calf viability and growth, on the reproductive performance of cows and on the overall productivity of Ndama herds in the village of Nioro Jattaba in the Kiang West District of The Gambia.


Agyemang, K.Dwinger, R.H.Grieve, A.S.Little, D.A.[Studies on the effects of milking on calf growth and viability and on cow reproductive performance in traditionally managed N'Dama herds]Studies on the effects of milking on calf growth and viability and on cow reproductive performance in traditionally managed N'Dama herds

The incidence of short luteal phases and ovulations without oestrus was investigated in 42 primiparous Borana cows. Based on calving body weight, cows were allocated to either a control group with grass hay only or to a supplement group with a concentrate ration. Within nutritional groups, cows w...


Tegegne, AzageGeleto, A.Kassa, T.[Short luteal phases and ovulations without oestrus in primiparous Borana (Bos indicus) cows in the central highlands of Ethiopia]Short luteal phases and ovulations without oestrus in primiparous Borana (Bos indicus) cows in the central highlands of Ethiopia

The haematological values in N'Dama, German Brown, and N'Dama x German Brown crossbreds are examined. The mean haematological values for the crossbreds were compared with those for their pure bred parents. Data on packed cell volume, haemoglobin and red blood count values, mean corpuscular volume...


Olusanya, S.K.[Haematological studies in N'Dama, German Brown and N'Dama X Brown cows]Haematological studies in N'Dama, German Brown and N'Dama X Brown cows

This study investigates the household-level impacts of market-oriented dairy technologies (crossbred cows and complementary feed and management technologies) on in-comes, food and non-food expenditures, nutrient intakes, and health of pre-school children. A recursive econometric model was employe...


Ahmed, M.Ehui, Simeon K.Mohamed-Saleem, M.A.[Adoption of crossbred cow technologies and increased food security among smallholder dairy farmers in the East African highlands]Adoption of crossbred cow technologies and increased food security among smallholder dairy farmers in the East African highlands

The feeding value of fodder from two cowpea cultivars to a basal maize stover diet was investigated using fifteen lactating White Fulani (Zebu) cows. The two cultivars were IT-716 and 994-DP. Diet was constituted as 50g DM/kg live weight and each of the cultivars was supplemented at 50 % of the d...


Akinlade, A.Smith, Jimmy W.Raji, A.M.Busari, A.A.Adekunle, I.O.Adewumi, M.K.[Effect of two cowpea (Vigna unguiculata) fodder cultivars as supplements on voluntary intake, milk yield and manure production of Bunaji cows]Effect of two cowpea (Vigna unguiculata) fodder cultivars as supplements on voluntary intake, milk yield and manure production of Bunaji cows

Reports a study of the interaction between trypanosome infections and physiological status on health and productivity in N'Dama cattle managed under traditional husbandry practices in The Gambia. Discusses production environments and herd management, parasite kinetics, erythropoietic response and...

The objective of this study was to assess the reproductive performance of two Nguni ecotypes (Nguni and Landim) raised in a subtropical environment to enhance strategies for livestock development and restocking programmes within the southern African region. Reproduction data collected between 199...

The experiment was carried out over three seasons during which a total of 889 Afrikander and 805 Simmental 'cow years' were studied. Nucleus breeding herds of each of these breeds were maintained at stations in the Highland Sourveld and the Valley Thornveld. At weaning, half of the progeny of eac...
