An insect-borne virus taking a toll on deer has spread to some Kentucky cattle herds.
Cattle farmers were already struggling with a shortage of feed supplies caused by weather setbacks.
Wade Northington is the director of an animal diagnostic laboratory in western Kentucky.
He says epizootic hemorrhagic disease, or EHD, was detected by his lab in 20 to 30 cattle that died in recent weeks.
The disease can NOT be contracted by humans, but is spread to deer or cattle by biting gnats or flies.
Northington says horses do not appear to be susceptible to the virus.
He says some veterinarians suspect that some cases of aborted calves may be due to the disease.
