In Kenya’s Northeastern Province, pastoralism is the main livestock production system and means of livelihood. However, pastoralists are facing increasing risks such as drought, insecurity, animal diseases, increasing human populations and land fragmentation. This study sought to evaluate household livestock herd structures and dynamics in view of such risks and subsistence and market demands. The study was conducted in Garissa County of Kenya, using a cross-sectional household survey. The data was analysed for descriptive statistics of household livestock status, dynamics and demographic parameters. The results showed that females of reproductive age formed over 50 % of all livestock species. Cattle had the highest turnover and all species’ mortalities accounted for the greater proportion of exits. Cattle had the highest multiplication and growth rates, but also the highest mortality, offtake, commercial offtake and intake rates. Goats had the lowest mortalities, offtake, commercial offtake and intake rates. Overall, the herds were structured to provide for both immediate and future needs in terms of milk, sales and herd replacement as well as for rapid recovery after disasters. The livestock herd dynamics indicate efforts at culling, restocking, retention of valuable categories of animals, and natural events. Livestock populations would be annihilated over time if the trends in end balances and negative growth rates were to continue and not be interrupted by the upward phases of the livestock cycles. It was recommended that the Government and development partners should undertake interventions to balance the herd dynamics in favour of entries by improvement of reproduction and reduction of mortalities, and support livelihood diversification to reduce dependence on livestock.
