Gyranda Santa Gertrudis Stud is built on more than half a century of breeding experience. It is Stud 3 on the Australian register, a title Gyranda proudly promotes in its logo.

The Gyranda stud operation began with the purchase of a King Ranch bull in 1953, and the importation of three purebred Santa Gertrudis cows from the Armstrong Ranch (USA) in 1954. Founded by Fitzpierce and Eileen Joyce, Gyranda was later run in partnership with his sons E.B. ‘Barney’ and Raoul Joyce. In 1967, the Eidsvold Station based partnership was divided.

Gyranda Pastoral Company was then established by Raoul Joyce and his wife Ida. Ida Joyce-Smith was a proud patron of the Santa Gertrudis Breeders Association Australia (SGBAA) until mid-2006, standing down just weeks prior to her death on 9th September, 2006. Burnett Joyce, the second of Raoul and Ida’s four sons, established the third generation of ownership in the 1970’s with his wife Louise.

Today, under the management of Peter and Nikki Mahony (Nikki the eldest of Burnett and Louise’s four children) the stud joins 1500 females and sells in excess of 200 herd and stud bulls annually.
