Sheep Genetics (SG) is the largest and most comprehensive across flock sheep genetic benchmark in the world.
Lambplan provides data services for the prime lamb breeds & Merinoselect serves the wool and sheepmeat industry based on the merino.
There is significant overlap in carcase & disease traits which are common to both, still, caution is needed when comparing different breeds of sheep.
Australian Sheep Breeding Values (ASBV’s) are the common genetic language used.
ASBV’s are provided in the Petali White Suffolk catalogue for these important traits:
WWT estimates the genetic difference in body weight at weaning or 100 days of age.
PWWT estimates the genetic difference in body weight at 225 days of age.
PFAT estimates the genetic difference in fat depth at 45kg live weight.
PEMD estimates the genetic difference in eye muscle depth at 45kg live weight.
BWT estimates the genetic difference between animals in live weight at birth.
PWEC estimates the genetic difference in worm burden at 225 days of age, expressed as a % relative to a count of 500 epg.
WEC ASBV describes the value of an animal’s genes for carrying worm burdens – a combination of being genetically less likely to pick up worms (resistant) and being able to cope immunologically with worm burdens (resilient).
The Lamb 2020 index has been developed to suit terminal sire breeders with clients targeting a 22 kg lamb carcass, from either a Merino or first-cross ewe base where worms may be a significant challenge to lamb production.
