Ticks Take Toll On Cattle

Following a treacherous winter, some ranchers in western South Dakota are already having an even worse spring. Hundreds of cattle have died and officials believe an infestation of winter ticks may be to blame. There are usually around 200 head of cattle grazing on the May ranch near Kyle. But in less than two months, a quarter of them have mysteriously died...two in the last two days. "Fifty-four head. Doesn't seem to be an end in sight. We've been doing this for thirty years. Never. Never seen anything like this," rancher Liz May said. The Mays aren't alone in their struggles. Veterinarian Norma Headlee says this season, she's seen about 250 individual cases of animals dying after being bitten by a winter tick...KELOLAND
