Australian Sheep Breeding Value Definitions
Weight (kg) WT
Estimates the genetic difference between animals in live weight.
Birth:BWT estimates the genetic difference between animals in live weight at birth.
Weaning: WWT estimates the genetic difference between animals in live weight at 100 days of age.
Post Weaning:PWT estimates the genetic difference between animals in live weight at 225 days of age
Maternal Weaning Weight (kg) MWWT
MWWT ASBVs are an estimate of the ewe’s potential for milk production and ability to provide a better
maternal environment. They are expressed as kilograms of live weight at 100 days of age (weaning).
Fat Depth (mm) FAT
Estimates the genetic difference between animals in fat depth at the GR site.
Post Weaning:PFAT estimates the genetic difference in GR fat depth at 45kg live weight.
Number of Lambs Weaned (%) NLW
Estimates the genetic difference between animals for number of lambs weaned at each lambing opportunity.
Fleece Weight (%) FW
Estimates the genetic difference between animals for greasy (G) or clean (C) fleece weight.
Note: Both greasy and clean fleece weight are expressed in percentage terms.
Yearling:YGFW or YCFW estimate the genetic difference in fleece weight at 360 days of age.
Worm Egg Count (%) WEC
The WEC ASBV describes the value of an animals genes for carrying worm burdens - a combination of
being genetically less likely to pick up worms and being able to cope immunologically with the worm burden.
WEC ASBVs are expressed as a percentage relative to a count of 500 eggs per gram.
Post Weaning:PWEC estimates the genetic difference in worm burden at 225 days of age.
Rockdale 08-0037, a 346 son, was
selected as a ram lamb based on
type, thickness, correctness, and
Dwight has source and hand selected an number of SAMM rams from
the top SAMM producers in Australia, importing a 10 + year ram battery
of genetics. Dwight and Joshua have developed a long term,
sustainable breeding program with emphasis on feed conversion,
carcass traits and wool.
Campbell Lawrie, Lawral Park, Ungarra, South Australia."
"This is a real sire of the future," he said. " He has an width
with a real leg in each corner stance and his natural
exceptional loin, a strong sirey head, great length and bare
breech is a major bonus for the industry going exceptional
loin, a strong sirey head, great length and forward."
