Poll Merino Sires

Improving Flock Genetics

The Poll Merino Stud Breeding Objective

The Poll Merino Flock is driven in a direction with more emphasis on figures and breeding values.

We were one of the first Merino studs to identify and start to measure for fat and muscle depth back in 1999 and recognised it’s benefits through the millennium drought.

The underlying physicality and functionality of the sheep has always been classed based heavily on visual selection, but sire selection has been based more on trait leading ASBV’s for rapid early growth, improved carcass quality and increased fertility, lamb survival and worm resistance.

The main genetic measured traits focused on are genetic fat, muscle, yearling and post weaning growth and high fleece weights with good worm resistance figures.

Poll Merino Semen Sires

“80% of the most Important Traits… We Can’t see!”

We are breeding a sheep that has never existed until recently, it does not look like a traditional Merino because it is not.

At Roseville Park, we breed a Modern Poll Merino sheep that is at the leading edge of carcass traits, growth, wool production and reproductive capacity, all delivered on a sheep that has lower labour requirements and feeding costs.

The things that you can’t see in a sheep are often the most important maternal traits- reproduction rates, mothering performance, fat, muscle and internal parasite resistance are all key traits leading to a profitable Merino Enterprise.

Measuring genomic DNA information allows us to see into these traits and identify Poll sires that will drive our industry forward.

Optimus prime family

Within the industry there are sires that tick all the boxes for growth, muscle, fat, number of lambs weaned, fleece weight and worm resistance.

For the past ten joining’s at Roseville Park, we have identified and used these rams in the yearly Embryo Transfer program over our leading Poll ewes that have had exceptional wool and body structure. These sires have been joined to 2,000 Poll ewes since 2014.

The top Ram Lambs have hit a massive 60 kg at 16 weeks of age out of these ewes. The ewe lambs make excellent mothers and could be used as Maternal breeders for prime lambs.

A large number of these rams have been available over the past three years, with numbers increasing every year to over 1,000 sale rams with these traits. Adult ewes are weighing up to 81kg at CS 3.2 and are producing over 8 kg of 18 micron wool and 120% + lambing.

If you want more lambs, faster growth with Roseville Park wool quality and production don’t miss the – OPTIMUS PRIMES. It will TRANSFORM your flock.

What They Say

Don't just take our word for it

“Within three years of changing bloodlines to Roseville Park genetics, we have had an increase in fleece weights by one kilogram, body weights increased by 10KG and weaning rates increased by 10% across the whole flock.”

Mark McGinneskin

Lingara, Mockinya Victoria

“We buy Roseville Park genetics because they are a long established parent stud. The wool quality of Roseville Park Sheep seems to get better year after year.”

Ken and Jan Heywood

Bowman’s Forest Wangaratta, Victoria

“We buy Roseville Park genetics because of sheep size for micron and the wool type suits our country and rainfall. We have zero fleece rot. Roseville Park sheep have improved the wool type by selecting for crimp definition which in turn has reduced micron and increased fleece weights.”
