When I began sheep farming, I never imagined one breed could make such a difference—until I met the Booroola Merino Sheep. These wooly wonders are famous for their sky-high lambing rates and fine fleece. Coming from the renowned Merino line, what truly sets them apart is their fertility—triplets and even quadruplets are common! In this guide, I’ll share their origin, traits, care tips, and the genetic magic behind their success. Whether you’re a farmer looking for high ROI, a breeder wanting better fertility, a hobbyist exploring sheep farming, or a pet owner seeking a friendly, independent companion—this one’s for you.
History & Origin of Booroola Merino Sheep
The Booroola Merino’s story begins in the Southern Tablelands of New South Wales, Australia. They were developed on the Booroola property near Cooma, hence the name. These sheep were selectively bred from highly fertile ewes within the larger Merino sheep population.
The game-changer came when researchers discovered the secret behind their super fertility: a dominant FecB gene (commonly called the Booroola gene) located on sheep chromosome This gene is responsible for increased follicle stimulating hormone (FSH) levels in the ovaries, leading to multiple ovulations and, therefore, more lambs per litter. The FecB gene is a genetic jackpot, increasing ovulation rates and can be reliably passed down, allowing for the prediction and planning of multiple births.
Their genetics trace back to the Garole sheep from Bengal, which also carry the FecB gene. It’s pretty wild to think how a gene from a small Bengal sheep helped shape one of Australia’s most prolific breeds. Today, Booroola Merinos are celebrated worldwide for both their fertility and wool quality.

Characteristics of Booroola Merino Sheep
Booroola Merinos carry many of the classic Merino sheep characteristics but with added benefits. Their wool is soft and fine, often used in luxury garments. The fleece is dense and covers much of their body, even the face and legs in some cases.
What’s really fascinating is their reproductive traits. Unlike other breeds, they often birth triplets or more. It’s not uncommon to see a single ewe raise three or four lambs. They’re medium-sized, and their body weight ranges between 50-80 kg, depending on sex and diet. Their Merino sheep color is typically white, though minor variations occur. The fleece yield per sheep can range from 3.5 to 6.5 kg annually, making them valuable from both meat and wool perspectives. That combination of quality wool and high lambing rate is what keeps me coming back to this breed.

Nature & Temperament
If you’ve worked with Merino breeds before, you’ll find Booroolas to be similar in temperament. They’re generally docile, smart, and easy-going, which makes them a joy to raise. But due to their high lambing rates, they require a bit more hands-on care during birthing season.
Lambing can get hectic. I’ve had ewes birth four lambs in a single night! Still, they’re usually attentive mothers and adapt well to structured routines. They do well in herds, making them suitable for both large and small farms. If you’re a new farmer or even just raising a few sheep as a hobby, Booroolas are a solid choice—as long as you’re ready for a whole lot of lambs!

Food & Diet
You can’t expect high fertility without proper nutrition. I always make sure my Booroola Merinos get a balanced diet rich in energy, protein, and minerals. High-quality hay, grains, and pasture are the staples.
During breeding and pregnancy seasons, I add supplements like molasses, lucerne, and calcium/phosphorus mixes. Clean water is a must, especially in the heat. Pregnant ewes need a little extra TLC with added vitamins like selenium and vitamin E to prevent complications. Avoid feeding them moldy or low-quality feed. It can harm both the ewe and her unborn lambs. Healthy moms make healthy lambs—every time.
Usage & Purpose
You can’t talk about Booroola Merinos without discussing their dual-purpose nature. These sheep excel in wool production and lambing. Their fine fleece is used in high-end textiles. On the other hand, their prolific breeding means more lambs to sell, raise, or process.
In fact, they’re often crossbred with other breeds like Poll Merino, Delaine Merino, and German Mutton Merino Sheep to enhance fertility traits. You’ll even see them used in breeding programs with Small Tail Han Sheep and Fonthill Merino Sheep. For small-scale farmers or large-scale producers, Booroolas offer great return on investment. More lambs mean more product and more profit.
Special Features
The standout trait? That FecB gene. It’s the holy grail of sheep fertility. It increases ovulation rates and can be passed down reliably. That means you can predict and plan for multiple births.
Another fascinating detail is how this gene affects granulosa cells in the ovaries, which respond to follicle stimulating hormone at higher levels. It’s a natural fertility booster. The Booroola Merino is also known for out-of-season breeding, so you’re not stuck with one lambing window. Their adaptability to different climates, strong immune systems, and efficient feed conversion make them a dream for breeders looking to scale up. Whether you’re in a hot, dry climate or a cold, wet one, these sheep can thrive, giving you confidence in your farming operation.

Health Issues & Prevention
More lambs mean more chances for complications, so health monitoring is crucial. The main concerns are:
- Birthing complications due to multiple lambs
- Nutritional deficiencies during pregnancy
- Internal parasites in crowded paddocks
I follow a strict vaccination and deworming schedule. I also give special attention to ewes during lambing season—watching for signs of distress or malnourishment. Proactive care, like hoof trimming, shelter during rain, and stress management, goes a long way. It’s a testament to your commitment to your flock. The healthier your ewes, the better your lamb survival rate, and that’s a responsibility every farmer takes seriously.
Step-by-Step Farming Guide
Raising Booroola Merinos takes a little planning, but the payoff is huge. Whether you’re new or experienced, here’s a step-by-step plan that works.
Step 1: Setup Your Shelter And Paddocks
Build well-ventilated, dry shelters. Booroolas can handle different climates, but lambs need protection from cold and wet conditions. I use rotational paddocks to manage grazing and avoid overgrazing. Keep at least 10-12 square meters per sheep and use quality fencing. Set up fresh water tanks and mineral blocks.
Step 2: Choose Quality Breeding Stock.
When selecting breeding stock, it’s crucial to consider the FecB gene. Breeding Booroola Merinos involves careful selection and planning to ensure the gene is passed down reliably. This process can be challenging, but the rewards are significant.Buy from trusted breeders. Look for genetic testing that confirms the FecB gene. Inspect the sheep for healthy fleece, alertness, and good hooves. I always ask about their lambing history. You want ewes that can support multiple births.
Step 3: Feeding For Fertility And Growth
Provide free-access to clean water and rotate pastures to keep grass fresh. Supplement with grains, especially during breeding and pregnancy. Add calcium, phosphorus, and vitamin mixes for pregnant ewes. Don’t forget salt licks and trace minerals!
Step 4: Breeding And Lambing Management
Time your breeding season wisely. You can breed year-round, thanks to their out-of-season fertility. Track ovulation and use fertile rams. Plan lambing pens with clean bedding. During lambing, I check every few hours. Keep colostrum on hand in case a lamb doesn’t nurse right away. Triplets or quads? Be ready to bottle-feed.
Step 5: Health Checks And Vaccination
Vaccinate early for clostridial diseases. Deworm regularly and treat external parasites. Check hooves monthly. A weak ewe can’t handle multiple lambs. Always quarantine new sheep before adding them to your herd.
