Audio slideshow: Sudan's love of cows

The people of Southern Sudan are preparing for independence from the mainly Muslim and Arab north - but as politicians weigh the future, many ordinary southerners are worried about their cattle that graze the grasslands that will be divided by the new border.

For the Dinka people of Northern Bahr al-Ghazal state, cows take precedence over almost everything else.

But during the long years of war between north and south this migration was accompanied by violence, killing and rape.Watch The Slide Show
