Incidence of neurofibroma in cattle in abattoirs in New South Wales.

The incidence of neurofibroma in slaughtered cattle in New South Wales during a four-year period is reported. Most of the cases were in adult Hereford females over 5 years old. In 24 of the herds to which neurofibroma cases were traced there was evidence that the disease had previously occurred in the herd. However, the data does not indicate close familial relationship among cases of neurofibroma.
