Riverglen is both a commercial and stud enterprise, operating on 5686ha of Brigalow/Belah/Box country near Glenmorgan, Qld. David and Penny Sullivan work and manage Riverglen with the assistance of Michael Sullivan.
John and Lenore Sullivan, David and Michael’s parents, visited Les Halles Meat Market, Paris in 1965 and were impressed by the high meat yield from Charolais and Charolais cross carcases.
The Riverglen Charolais breeding program began with an AI program in 1971 and resulted in 98 first cross calves being born to Santa Gertrudis, Hereford and crossbred cows. Large AI programs were run for several years and purebred bulls purchased in 1973.
The first Riverglen purebred calves were born in 1978. The Riverglen herd now consists of approximately 400 purebred breeders. We continue to crossbreed Riverglen Charolais bulls with Santa Gertrudis / Hereford cross cows to produce prime steers.
Our objective has been to breed functional Charolais cattle that are highly fertile, easy calving, structurally sound, fast growing, easy finishing and meet market specifications. Years of careful sire selection and strict culling, has ensured real depth of breeding in the Riverglen herd.
Riverglen bulls have sired progeny in many herds that have topped the market as weaners, feed-on steers, replacement heifers and finished slaughter stock. Many of these Charolais cross cattle have been successfully exhibited in commercial shows and sales, prime cattle and carcase competitions.
Breeding purebred Charolais with a commercial focus means cows and heifers are joined naturally and must calve unassisted. Heifers must achieve bench mark daily weight gains to be joined. Fertility, milking ability, structural soundness and resilience to drought are features of Riverglen Females.
Sale bulls are selected primarily on their ability to put on flesh in the paddock without extra feeding. Riverglen bulls are bred naturally and our low maintenance high milking cows calve unassisted. Weaning to buffel grass occurs in late Autumn. Grazing grass and pasture continues until sale date. A short sale preparation is a ration of home grown sorghum silage with a low percentage of grain available in a 700 acre paddock some 600 meters to water. Bulls are sold ready to work and do not carry excess condition.
Riverglen’s commercial cross breeding herd and culled brothers and sisters of sale bulls have given us excellent returns as steers and heifers for slaughter. Feedback sheets are analysed to improve grid money and fit abattoir specifications.
