The research and development community faces the challenge of sustaining crop productivity gains, improving rural livelihoods and securing environmental sustainability in the Indo-Gangetic Plains. This calls for a better understanding of farming systems and of rural livelihoods, particularly with...

Carcass characters for 365 male castrated cattle of the Africander, Angoni, Barotse and Boran breeds, and the reciprocal crossbreds of the latter three were reported. In each of the two year-of-birth groups, different slaughter-age/management regimes were used. For all carcass characters except t...

Live weights from birth to 3.5 years are reported for beef cattle reared under ranching conditions in Zambia. The 809 cattle were purebred Africanders, Angonis, Barotses and Improved Borans and the reciprocal crossbreds of the latter three breeds born in 2 years. All animals born in the 1st year ...

Dam reproductive performance of purebred Africander, Angoni, Barotse and Boran, and reciprocal crossbreds of the latter 3 breeds under ranching conditions were investigated. Mean performance based on a maximum of 1996 records collected over six parities were: calving rate, 65.6%; weaning weight r...

Factors influencing reproductive performance of Angoni, Barotse, and Boran under ranching conditions are examined. Five years reproduction records of 675 Angoni, 731 Barotse and 815 Boran were analysed. Calving percentages were 82.5, 78.1 and 75.4 for Angoni, Barotse and Boran, respectively. Year...

Crossbreeding parameters and variance components were estimated for lactation and reproductive traits of crosses between the Sahiwal, Brown Swiss and Ayrshire breeds in a dairy herd in sub-humid coastal Kenya. An individual animal model was fitted to the data with a fixed effect for 20 distinct b...

Records from 1577 cows borm from 1973 to 1983 on a ranch in lowland Kenya were analyzed for age at first calving, lactation length, lactational milk yield, calving interval, annual milk yield, and, for cows born from 1973 to 1979, number of calvings, productive lifetime in the herd, and lifetime ...

The role of livestock in nitrogen cycling in mixed crop-livestock farming systems of sub-Saharan Africa was explored. Cattle were fed a range of diets to investigate the effects on partitioning of nitrogen between urine and faeces and on the chemical composition of the manures produced. The trade...

Liberalisation in the dairy industry in Kenya is currently under way in several forms. The urban milk market monopoly of the Kenya Co-operative Creameries has been lifted. Clinical veterinary and artificial insemination (AI) services are no longer publicly supported in many areas. Private sector ...
