Contractural Arachnodactyly

THE ‘FAWN CALF SYNDROME’ - REQUEST FOR INFORMATION

Scientists from the University of Sydney, the University of New England, and NSW Agriculture have recently been contacted by beef breeders to investigate a possible new inherited syndrome in cattle called "Fawn Calf Syndrome".

Reporting Abnormal Calves - Fawn Calf Syndrome

As we continue our work to characterize and head off emerging problems, we are also carefully monitoring a non-lethal condition referred to as fawn calf syndrome (FCS). Calves suspected to have FCS have been reported in Angus calves in Australia for many years and researchers there have identified the condition as an inherited trait allegedly tracing to U.S. sires. If the Australian hypothesis is correct, and there is strong evidence that it is, there are almost certainly cases unintentionally not being reported in the United States.
