Animal, Vol 3, Iss 7, Pp 1044-1056 (2009)
Evaluation of lifetime productivity is sensible to target interventions for improving productivity of smallholder dairy systems in the highlands of East Africa, because cows are normally not disposed of based on productive reasons. Feeding strategies

In large regions of sub-Saharan Africa, semi-arid conditions are likely to increase with climate change, yet these regions are becoming more important to feed production zones due to increasing population pressure. A production system in the semi-ari

We systematically reviewed the literature on farm household models, with emphasis on those focused on smallholder systems. The models were evaluated on their predictive ability to describe short term (3–10 years) food security of smallholder farm h
