                Breeding Objectives

We aim to produce sheep that perform well and are profitable even under unfavourable seasonal conditions and at high stocking rates.

We believe wool cut and quality do not have to be sacrificed in order to breed faster growing, meatier sheep with worm resistance.

Our rams now are some of the most highly worm resistant in the Sheep Genetics database for all of Australia, with some of the highest eye muscle definition, fat and growth rates.

The 2018 sale catalogue shows Anderson Rams are achieving outstanding results in all key production traits, with many rams having multiple ASBVs in the top 1%.

Over 60 traits are recorded on each animal in the nucleus flock from birth to hogget age- both objective and visual- in order to refine selection and provide accurate breeding values for each sheep.

For over 50 years our rams have been progressively selected for:

  • 20170717_120132
  • Fine, soft, white wool
  • high wool cut
  • plain bodies
  • worm resistance
  • eye muscle depth
  • fast early growth
  • fertility
  • C site fat (increases fertility and resilience)
  • clean faces and points
  • calm temperament



We actively select against dags, fly data collectionstrike, pigment, fleece faults and dry sheep.

Anderson Rams are run in paddocks all year round under commercial conditions at high stocking rates and are not shedded or preened for sale.



The Anderson Rams Genetic Trend charts our genetic progress compared to other studs in Australia.



We have benchmarked our genetics against other studs through sire evaluation trials in Balmoral and North East Vic in Victoria, Yardstick in WA, New England  in NSW, South Australia,CPT in New Zealand, and have rams entered in Merino Lifetime Productivity trial at Pingelly WA in 2017 and at Macquarie, NSW in 2018.



Anderson Rams and semen have been sold around Australia and even into New Zealand, Uruguay and the Falkland Islands, into a variety of climatic environments including high summer and winter rainfall areas. It is pleasing to see our 50-year history of selection against wool faults, and 15 years of selection for worm resistance has produced rams that perform well in any environment.



2016 was an amazing season for pasture growth and in November we weaned lambs to an outstanding 50kg at 12-17 weeks.


Proof of what selecting for fast early growth can achieve when feed is not limiting.


We consistently mark over 100% lambs from ewes mated. in 2019 after a tight feed year we marked 108%. Lamb survival rates are regularly 95% for singles and up to 181% for twins.
