Where genetics and innovation combine to unlock the full potential of your flock.


We’re pushing the boundaries in our quest to breed Merinos of the future. Our superior genetics are a result of decades of risk-taking, experimentation and learning. Proudly 19-years mules-free, we’re tackling major animal welfare issues head on as we continuously strive to breed the most robust and productive easy-care sheep to meet modern market demands.

We're challenging the belief that Merinos can't match composites in fertility. We have to produce more lambs from less ewes and to do this we need highly fertile sheep, but also sheep that have genetics that can successfully raise twin born lambs.


We invite you to join us in helping to shape the future of the sheep industry.

Tailor-made genetics.

Moojepin Merinos is a progressive and commercially focused sheep breeding enterprise. We are dedicated to pushing the boundaries in genetics and breeding to improve sheep production, performance and profitability.

Our approach is balanced and holistic with a specific focus on reproduction and animal welfare traits. We are committed to producing an animal with high welfare traits alongside productivity traits when it comes to our genetic offering. 

We understand the importance in matching phenotype to genotype to ensure the sheep that test well genetically also have high animal welfare traits to move into the future.

Our aim is to create a highly fertile sheep that can thrive in an increasingly harsh climate, and ensure Australian wool is the fibre of choice for buyers who choose products based on ethics as much as economics.​​

Our Genetics

We understand that every farm and every flock is unique. That's why we offer tailor-made Merino sheep genetics that are customised to meet the specific needs and goals of our clients.


ASBV's has allowed us to make significant genetic gain. We have pedigree records for over 3 decades ensuring our data is at the highest integrity. You can't improve what you don't measure!

High Early Growth



Genetics with exceptional early growth are a key catalyst for profitability since weight directly impacts earnings. Our genetics are highly sought after by lamb finishers and feedlots. They possess the advantageous trait of quick conversion, resulting in shorter feeding periods. This grants flexibility in determining the optimal timing for selling.

High Muscle


Optimal growth requires a harmonious combination of muscle and fat. Building substantial muscle mass not only enhances carcass composition and increases meat yields but also aids in controlling overall adult weight.

High Fat


Fat is a cost-saving asset. It significantly reduces feed expenses and plays a crucial role in maintaining an ideal condition score.

Fat empowers sheep to thrive even in suboptimal feeding conditions, which is particularly vital for ewes carrying twins. It contributes to their robustness and enhances the overall eating quality.

Animal Welfare Traits

Consumers increasingly want to know where their products come from, which is why we place importance on animal welfare traits such as zero tolerance for wrinkle (EBWR), dag, WEC (worm egg count).

Reproduction, Early Maturity & Fertility

Having high lambing and the ability to join ewe lambs, has meant we, along with many of our clients, have to opportunity to sell  lines of younger ewes at above market prices, or rapidly increase flock size.

We select sires on YCON to make ewe lamb joining more predictable. 

Fast Growing, High Quality, Soft White Wool

Since 2013, Moojepin Merinos are shorn twice per year at 70mm staple of high tensile strength (NKT), low mid-break and high-yielding at 70%.

Our aim is to increase to 80mm in length. Our staple length is unmatched by any seedstock Merino breeder.

Our Clients Say


Chippa Gordon
Commercial Client, VIC

Over a decade ago, we purchased our foundation Merino ewes from a long-term Moojepin client in WA. We continue to use Moojepin genetics because of their high fecundity, ability to bounce back in poor seasons and the superior production of a prime lamb. Being a maternal flock, Moojepin genetics gives us the opportunity to join ewe lambs with success, be non-mulesed and produce a high value merino wool from an easy care sheep. Moojepin Merinos, ticking all the boxes - taking our family farm forward.

Our Team

We're a third generation, family-operated business.
