Murray Grey Cattle

The Murray Grey cattle are a breed of beef cattle from Australia. It was developed in the upper Murray River valley on the New South Wales. The breed was developed in 1905 from an initial chance mating of a black Aberdeen Angus bull and a roan Shorthorn cow during the Federation drought.
