The first GDL In the Tank Genetics Sale held on Stocklive, last Thursday and Friday, proved a hit, with many stud breeders securing ‘once in
“We would like to commend the Rockley family on the exceptional quality of the bulls we have purchased this year and previously. These bulls are impeccably bred, functional for our region and a delight to muster (by bike or horse). As beef producers it is paramount that our progeny do well at all stages, from calf to ox – this is what we are in business for!
Rockley provides a real bull for real cattlemen that are suited for all areas. If you want to improve or add both body and vigour to your existing herd, Rockley bulls won’t disappoint you.”
Tom talked about how well bull brothers Tyrion and Renly were performing, making special mention of characteristics that directly reflect Rockley’s Elite Breeding Attributes:
Tom is “extra pleased” with the calves by Renly, a light pigmented sire that crosses well with Yoman females, a high percentage of which are also light pigmented. Renly has bred progeny consistently like himself, which has provided good value for money for Yoman Brahmans.
“Tyrion is breeding a high percentage of polled/scurred progeny, crossed over both polled and horned females and has bred a couple of standout calves”, said Tom.
“After using a number of different bulls over our 80-100 breeders over the last 18 years at Millaa Millaa (Southern Tableland) when it came time to choose our latest sire we were looking for something that suited our climatic conditions, high cattle tick load and need to produce saleable beef. Also looking to retain a number of females for future breeders we wanted a quiet bull with very good conformation (particularly in body length, width and height) and with an outstanding growth rate. After doing a lot of research we purchased “Big Red” from Rockley Brahmans. We are very happy with him and recommend anyone looking for a Brahman Bull to make sure they consider Rockley.”
