Greyman

Cattle

Greyman are an Australian breed of beef cattle developed in Queensland in the 1970s, specifically to suit the Queensland environment, by combining the outstanding genetic characteristics of both the Murray Grey and Brahman (cattle) breeds. These cattle carry between 25% and 75% of Murray Grey blood, with the remainder made up of Brahman. This allows breeders the option of being able to select for optimal performance specific to the region and environmental conditions. Thus, Greymans can be bred with a greater emphasis on Brahman content in the tropical country, or with a higher percentage of Murray Grey blood to suit the southern states. Their sleek coats varying in colour from dark grey to a silver, the Greyman are natural polls and have a dark skin pigmentation that is not susceptible to skin or eye problems in severe climates.
