Conventional productivity evaluation criteria are inadequate to evaluate subsistence livestock production, because: (1) they fail to capture non-marketable benefits of the livestock; and (2) the core concept of a single limiting input is inappropriate to subsistence production, as multiple limiti...

Crossbreeding of goats in traditional subsistence flocks had been promoted in selected villages of eastern Ethiopian highlands as a means to quick genetic progress based on the thesis that crossbreeding can increase the net contribution of goats. Observations on flock dynamics patterns of smallho...

Examines the structure of the herds & flocks of a sample of 41 households on the three Maasai group ranches in Kenya, relating differences in herd structure to livestock wealth of the household, to the stage of development of the group ranch, & to the variation in climate and production alternati...

Over the last two decades, dairy cattle management in Malawi has been oriented towards increasing milk yield per animal. One consequence of this process has been reliance on Holstein Friesian bull semen from temperate regions. The aim of the current study was to evaluate the performance of Holste...

The 2002 World Summit on Sustainable Development focussed attention on agricultural sustainability and biodiversity in developing countries. These goals are relevant for livestock production in Kenya, where development agencies encourage resource-poor smallholders to acquire large, exotic, high-y...

This study evaluated the effect of bambara groundnut supplementation on the physicochemical properties of local rice flour and baked crackers. Bulk and true density, porosity, water absorption index, oil absorption capacity, pasting properties by RVA, morphological appearance by SEM, color by cal...

Low adoption rates of introduced technologies in spite of manifestly increased production suggestthat livestock developer and farmer value livestock differently. The purpose of this paper is torelate productivity more closely to the perspective of the farmer. The concept of productivity isreviewe...
