Beyond the Bale : December 2018
Analysing wether trial data gathered over a 10-year period to 2018, the new Merino Bloodline Performance package compares many commonly used Merino bloodlines to identify performance differences and subsequently the best ram source for specific breeding outcomes. BLOODLINE ANALYSIS HELPS BUILD PROFITABILITY The new report, funded by AWI and NSW Department of Primary Industries (DPI), has delivered important information to Merino breeders with implications on the profitability and performance of 73 Merino bloodlines. NSW DPI development officer, Kathryn Egerton-Warburton, said Merino Bloodline Performance 2007-2018 delivers objective production data which can inform growers of the variation between the bloodlines and assist them in their choice of ram source. Analysis of nine individual traits and four financial indicators from 24 wether trials in NSW and one in Tasmania show significant variation between the bloodlines. Merino bloodlines varied across a range of 3.6 microns in fibre diameter, 28 per cent in clean fleece weight and 13 per cent in live weight and the production differences translate into very significant differences in bloodline profitability. “Significantly there was a strong relationship between fleece weight and fibre diameter across the bloodlines, with a significant genetic variation across the fibre diameter range,” Dr Egerton-Warburton said. “This genetic variation offers two key options to fit breeding objectives – producers can choose a finer bloodline to reduce fibre diameter without compromising clean fleece weight or choose a bloodline with a heavier fleece weight and maintain their current fibre diameter.” Merino breeders and commercial wool producers can use the updated report to identify the relative performance of bloodlines and fine-tune their future breeding programs. Determinants of profitability, including diameter, fleece weight, live weight, staple length and strength, style and colour, and measures of financial performance allow producers to compare bloodlines on a There are five steps commercial wool producers can take in order to maximise their profitability and make the best use of the Merino Bloodline Performance report: 1. Set a long-term breeding objective 2. Benchmark your current bloodline performance against other bloodlines 3. Consider all traits, even though some will be dominant 4. Consider performance and future progress of the bloodlines that are of interest 5. Consider practical constraints of a bloodline, such as price, availability and location. FIVE STEPS TO MAXIMISING PROFITABILITY Merino bloodline performance Which bloodline will make you the most money? profit per head or per dry sheep equivalent (DSE) basis. Dr Egerton-Warburton said Merino producers can confidently use the data in selecting bloodlines which best suit their breeding objectives. “The trials have each run from two to three years and we are confident the information gives a very reliable indication of potential Merino profitability,” she said. “Genetic data has been isolated from seasonal and geographic environmental differences by grouping multiple teams of wethers into bloodlines across the trial sites.” NSW wether trials were run in the Central Tablelands, Central West, Northern Tablelands, Riverina, Southern Tablelands and the Monaro. AWI and NSW DPI funded the Merino Bloodline Performance project. MORE INFORMATION www.merinobloodlines.com.au ON FARM 59
