Their particular breed of cows, which is the most common livestock (although since the drought has been very bad the last few years, there has been the introduction of camels), is called the 'boran breed' and is particularly suited to the arid landscape.
Anthropological studies of the Boran have been very interested in their being pasturalists, and nomads, or the combination of the two, but of special interest has been the 'Gada' or the borana system of Governance.
According to Dr. Ibrahim A. Elemo, who wrote 'The Life of Borana Oromo Gada Councilors: The Legacy of the Late Abba Gadaa Hiddoo Galgaloo' 'the Gada is made up of three assemblies of active leaders and their immediate family members called Ya’aa. These three assemblies have to undertake ritual migrations throughout the Borana land during their period of administration'.
As Galgalo Boru Galma, writes in the very informative essay on Boran culture: 'The Gada system is a system of generation classes that succeed each other every eight years in assuming political, military, judicial, legislative and ritual responsibilities. Each one of the eight active generation classes- beyond the three grades- has its own internal leadership (Adula hayyus) and its own assembly (ya’a), but the leaders of the class become the leaders of the nation as a whole when their class comes to power in the middle of the life course- a stage of life called “gada” among the Borana. The class in power is headed by an officer known as Abba Gada or Abba Bokku in different part of the Oromo nation.'(see full article here)
Here are two great videos(big up achacho), which give a real sense of the cultural values, and a look at the day to day life (although they were done in the 70's, so much has changed since then).
last but not least, here are a list of great links on articles, photos and essays....~http://www.frank-kappa.com/work/2009/kenya/
