what happened to the cows donated from Kenya to the United States after 9/11?

After 9/11, while no official offering was made by the Kenyan Government to the United States, a tribe within Kenya, the Masai Tribe, donated 14 cows to the United States.

What became of these cows? Were they official property of the US government, or given to a private company? where were they received, and how were they transported from Kenya to the United States?
