Southern Multi-Breed Project


Weebollabolla are proudly associated and supportive of the Southern Multi-Breed Project.

The Sheep EBV equivalent commenced it’s life without breed interference and we look forward to the cattle industry forging ahead with a Multi- Breed EBV. In June 2019 Weebollabolla sent 17 PTIC cows and 13 PTIC heifers to green grass at Tocal. The cattle were assessed for structure, pedigree linkage and EBV accuracies. We also nominated AI sires on July 31st to be apart of this program well into the future. Thank you to Andrew Lawrence and Jason Siddell for doing their job with great care.

Delivering resource populations for multi-breed genomic evaluation in beef cattle

This project will enable producers across Australia to directly compare bulls of different breeds for all BREEDPLAN traits and assess their genetic merit irrespective of hide colour. Currently BREEDPLAN EBVs and $Indices are breed specific, and cannot be compared across different breeds. Up to 5 breeds (Angus, Hereford, Shorthorn, Wagyu, Charolais and Brahman) representing the most popular breeds in Southern Australia will be part of the project.

EXPERIMENTAL DESIGN The aim of this project is to obtain calves which are born in a multi-breed context, which means that they are born head to head with other purebred animals from different breeds. This allows for similar environmental effects to be identified at the moment of recording, therefore allowing for the calculation of direct breed effects on all phenotypes recorded that will later be used for genetic evaluations. This is a mandatory requirement for establishing a multi-breed BREEDPLAN evaluation. The number cows and the number of breeds will depend on the location and size of the research station.Foundation cattle sourced widely from the beef industry will be tested head to head on NSW DPI research stations from conception to slaughter over the 5 years (2018 -2023) of the project. A total of more than 8,000 (head to head) calves will be born, 2,600 steers and close to 3,000 heifers retained for joining. A large number of traits will be recorded during the project.
