Fine-tuning finishing performance in beef cattle: outcomes from Beef + Lamb New Zealand Genetics’ Beef Progeny Test
Scene + Herd: Podcasts from Beef + Lamb New ZealandShow Notes
The Beef Progeny Test was a 5-year project run by Beef + Lamb New Zealand (B+LNZ) Genetics, comparing bulls under commercial farming conditions. B+LNZ Genetics has been analysing the dataset collected from those farms to identify valuable insights for stud breeders and commercial farmers. In this podcast, Jason Archer, Livestock Genetics Specialist at B+LNZ Genetics, delves into some of the insights on measuring and predicting finishing performance in beef cattle. Discussion explores the important role of 'subcutaneous fat', which is measured through rib fat depth, and 'intramuscular fat' also known as marbling, as well as the relationship between these traits. Jason also discusses different tools used to improve carcass traits – such as estimated breeding values (EBVs) and ultrasound scanning – and how effective they are at predicting marbling and rib fat depth within a carcass.
