Abstract: The utilization of pastoral resources such as grasses, shrubs, water and salt-licks is an aspect social capital. However, with climatic and socio-economic changes traditional cattle production and livelihood outcomes including social capital may be impacted. As a result pastoralists devise mechanism to ameliorate any negative effects of the changes. Governments and other agencies have also intervened in the pastoral production systems to align them to current realities. In 1991, the Government of Kenya and the Federal Republic of Germany introduced the Sahiwal cattle to the Isiria Maasai of Narok County to improve cattle production. Studies on the effect of such interventions on social capital are few and the existing ones are narrowed to at most three aspects of social capital. Thus, this study was formulated to investigate the association between adoption of Sahiwal cattle and household social capital among Isiria Maasai pastoralists.
