Buffalo are big, ugly and dangerously unpredictable. If free of disease, they are very valuable, but they are also great carriers of disease, and do need continual monitoring and testing. In Natal, four and a half thousand buffalo will be tested for bovine tuberculosis and those found positive will be culled. In the first half we see the Wild Life Vet Dave Cooper and the Game Capture team herding in buffalo with the help of a helicopter, darting and testing them. In part two- lion in the Kruger National Park are tempted to a nighttime feast so they can be darted and have both blood and semen samples taken. Professor Woody Meltzer and his team test for Bovine Tuberculosis, which they are catching from buffalo and Canine Distemper Virus- a disease which affects domestic dogs, and Feline Immunodeficiency Virus- which affects eighty per cent of the Kruger's lion. But the most important test is to show whether or not the lion is still a good breeder.
