I drove out to this property in hopes of photographing their camels. I didn't see the camels on this trip, but I did snap a few shots of these cattle, and from the info I found on the internet, this appears to be the breed:
Ankole-Watusicattle are the show-stoppers of the bovine kingdom. Medium-sized animals, with long, large-diameter horns, they attract attention wherever they appear. These regal animals can easily trace their ancestry back more than 6,000 years and have often been referred to as "cattle of kings."
