Consumers and processors desire tender, nutritious and high yielding lambs. Producers can use genetics to help deliver these qualities.

Rams can be chosen to suit any ewes and the target market for their lambs by using Australian Sheep Breeding Values (ASBVs); either through LAMBPLAN for meat breeds or MERINOSELECT for Merinos.

The currently well-used measurements of live weight, loin eye muscle depth and GR fat depth allow producers to effectively target the right carcase weight with the most appropriate fat score.

Exciting new work being developed between the Sheep CRC Meat Program and MLA has shown that a variety of eating quality traits are moderately to highly heritable. These include Lean Meat Yield (LMY), Dressing Percentage (DR%), Intramuscular Fat (IMF) and Shear Force (SF5), also known as tenderness.

Which ASBVs should be used?
When selecting to improve growth rates, use post weaning weight (PWT) ASBV. To select for increased muscle, use the post weaning eye muscle depth (PEMD) ASBV. These traits must be balanced and producers should aim for animals with higher growth, and a PEMD ASBV between 0.0 mm and 3.0 mm.

Fat is also an important component and the level chosen will depend mostly on the combination of breeds being used and the production system that is being targeted. When using a maternal or terminal sire over Merinos, choose a post weaning fat (PFAT) ASBV that is between -0.5 mm and 0.5 mm. Terminal sires used over 1st cross ewes can be selected between -1.0 mm and 0.0 mm.

To avoid lambing difficulties, look for birth weight (BWT) ASBVs that are between 0.1 kg and 0.3 kg. High birth weight is one of the key factors leading to dystocia (lambing difficulties). Very low birth weights should also be avoided as this can lead to light lambs that have little tolerance for cold weather.

RamSelect.com.au is a simple way to rank rams for your breeding objective. It uses the power of ASBVs in it's calculations.

Tech-savvy students drive Farrer High to the top of RamSelect
Listing their catalogue via the RamSelect Plus app has showcased the value of early adoption of new breeding technologies and opened new markets for the students at Farrer Memorial Agricultural High School. Based in Tamworth NSW, the school’s agriculture subject offering includes a Year 9 and 10 ‘animal management course’, in which students take on the tasks associated with running the Farrer White Suffolk stud.

DNA Flock Profiler responds to producers needs
Breaking down a perception-driven market with objective genetic data was the impetus for sheep breeders Andrew and Barbara Read to conceive an idea which has now been realised in the form of the Sheep CRC’s DNA Flock Profile test. The Reads, from "Oak Hills", Nangus, NSW, first approached Sheep CRC chief executive James Rowe two years ago at a producer field day with the idea of developing a DNA test to profile the genetic...

Commercial Merino producers - opportunity for DNA pilot project
Commercial Merino producers have the opportunity to be at the cutting edge of DNA research by participating in a pilot trial of the new Flock Profiling Test from the Cooperative Research Centre for Sheep Industry Innovation (Sheep CRC). The Sheep CRC will provide support for up to 100 Merino producers to define the genetic merit of their flocks. The profiling test involves randomly sampling 20 young ewes for DNA testing.
