Merino Bloodline Performance

The Merino Bloodline Performance analysis is a joint initiative between NSW Department of Primary industries (NSW DPI) and AWI.

Merino Bloodline Performance allows woolgrowers to compare Merino bloodlines based on the results of wether and ewe trials, run across Australia over the past 10 years.

The analysis takes out all known environmental factors between trials and years, leaving the remaining variation between the bloodlines due to genetic differences.

Merino Bloodline Performance highlights the diversity in wool production, wool quality and profitability for a wide range of bloodlines and allows woolgrowers to compare the strengths and weaknesses of each bloodline.

The 2018 results demonstrate significant variation in production between the 73 bloodlines, with a range of 3.6 ┬Ám in fibre diameter, 28% in clean fleece and 13% in liveweight. These production differences translate into very significant differences in bloodline profitability.

Commercial woolgrowers wanting to identify the best ram source to match their own breeding objective can use Merino Bloodline Performance to compare bloodlines evaluated at different trials and over different years.
