Ella Matta Poll Merino Genetic Trends Compared to Other Studs

MerinoSelect Australian Sheep Breeding Values (ASBV's) are an estimate of an animal’s true breeding value based on pedigree and performance recorded information. They are essentially a projection of how that animals progeny will perform for a range of traits. This is more effective than raw data as it accounts for environmental (i.e. feed, management, seasonal) effects.

MerinoSelect ASBV Definitions (Traits)

The below comments in relation to breeding objectives should only be used as a guide. Ram buyers should understand their individual markets/breeding aims and select accordingly.

Birth Weight (kg) BWT

Estimates the genetic difference between animals in weight at birth. It should not be too high or low in Poll Merinos as it can result in lambing issues (too high) or lamb mortality (too low).

Poll Merino Lamb


Weaning Weight (kg) WWT

Estimates the genetic difference between animals in live weight at 100 days of age. The higher the better.

Worm Egg Count (%) WEC

Value of an animals genes for carrying worm burdens – a combination of being genetically less likely to pick up worms & being able to cope immunologically with the worm burden. The lower the better.

Yearling WEC: YWEC

Estimates the genetic difference in worm burden at 360 days of age. The lower the better.

Yearling Weight (kg) YWT

Estimates the genetic difference between animals in live-weight at 360 days of age. The higher the better.

Yearling Eye Muscle Depth (mm) YEMD

Estimates the genetic difference in EMD at the C site at 60kg live-weight Level depends on breeding aims.

Yearling Fat Depth (mm) YFAT

Estimates the genetic difference in GR fat depth at 60kg live-weight Level depends on breeding aims. Should not be extreme either way.

Yearling Fleece Weight (%) YGFW or YCFW

Estimate the genetic difference in fleece weight at 360 days of age. The higher the Better.

Yearling Fibre Diameter (micron) YFD

Estimates the genetic difference in fibre diameter at 360 days of age. Depends on breeding aims, usually the lower the better.

Yearling Fibre Diameter Coefficient of Variation (%) YFDCV

Estimates the genetic difference in fibre diameter coefficient of variation at 360 days of age. Animals with a lower YFDCV will genetically have a lower variation in fibre diameter (preferred).

Yearling Staple Strength (N/Kt) YSS

Estimates the genetic difference in staple strength at 360 days of age. The higher the better.

Yearling Staple Length (mm) YSL

Estimates the genetic difference in staple length at 360 days of age. Level depends on breeding aims.

Number of Lambs Weaned (%) NLW

Estimates the genetic difference between animals for number of lambs weaned at each lambing opportunity. This not only accounts for fertility, but also survivability. The higher the better.

Lambing Ease Direct (%) LE DIR

Describes how easily a sire’s lambs will be born, with a positive number preferred.

Early Breech Wrinkle (EBWR)

Early breech wrinkle and body wrinkle have an estimated heritability of 0.35, which is similar to body weight, staple strength and eye muscle depth. Environmental effects also have a significant effect on the expression of wrinkle, sometimes called ‘feed wrinkle’. For example:

  • Twin born lambs are 0.3 to 0.5 score plainer than a single born lamb.
  • Maiden lambs are 0.2 to 0.3 score plainer than lambs from older ewes
  • Drought lambs are 0.5 to 1.0 score plainer than lambs born in good feed conditions.

Accounting for these feed effects is one of the reasons why a breech wrinkle ASBV has been developed. Negative is the preferred trait to reduce breech wrinkle.

MerinoSelect Index Options

Fiber Production Index (FP and FP+)

The Fibre Production (FP & FP+) indexes rank animals on their ability to produce merinos for a wool production operation.

The index is aimed at those producers whose majority of sheep income come from their wool clip. It is for self-replacing merino flocks who keep their wethers as part of their wool producing flock.

What makes up the FP and FP+ indexes?

Merino Production Index (MP & MP+)

The Merino Production (MP & MP+) indexes rank animals on their ability to produce progeny for a fine wool operation that has significant surplus sheep sales.

The index is aimed at those producers whose sheep income is a balance of both wool and surplus sheep sales. It is for self-replacing merino flocks who do not keep their wethers to produce wool.

Dual Purpose Index (DP & DP+)

The Dual Purpose (DP & DP+) indexes rank animals on their ability to produce merinos for a dual purpose operation.

These indexes are aimed at those producers whose majority of sheep income comes from sheep sales. It is for self-replacing merino flocks that do not keep their wethers and also join a portion of their ewes to terminal sires for lamb production.
