For commercial sheep farmers, few breeding decisions have a bigger long-term impact than the choice of ram. A ram’s influence extends far beyond next year’s lamb crop, affecting flock performance, replacement quality, lamb survival, growth rates, and overall profitability for years to come. That is why selecting a five-star ram should be viewed as an investment in the future of the flock, rather than simply a once-off purchase.
The 2026 Sheep Ireland Guide & Directory of Breeders sets out the key message clearly: farmers should use the €uroStar system to identify rams with stronger genetic potential for the traits that matter most on commercial farms. A five-star ram has been identified through Sheep Ireland evaluations as being among the top animals for either the replacement or terminal index.
This gives farmers a practical, independent tool to compare rams across flocks and breeds and to select genetics that are more likely to deliver measurable improvement.
More lambs, fewer problems
The 2026 Sheep Ireland Guide & Directory highlights a simple but powerful point: research has shown that five-star rams have fewer lambing problems, produce more lambs and help lambs reach slaughter faster. These are exactly the outcomes commercial farmers need. Easier lambing reduces labour pressure and losses at a critical time of year.
More lambs born and reared improves output per ewe. Faster finishing lambs can reduce days spent on farm, lower feed demand and improve the ability to hit market specifications.
In practice, the benefit of a five-star ram is not just seen in one trait. The real value comes from stacking small gains on many traits across the flock: better lamb survival, improved growth, stronger maternal performance where replacements are being bred, and more confidence that the ram being purchased has been evaluated using performance-recorded data.
Over time, this helps commercial farmers breed sheep that are more efficient, productive and suited to their system.
Choose the right index
The aim is to match the ram to the job he is bought to do. Farmers breeding their own replacements should pay close attention to the replacement index, which supports the selection of rams with stronger maternal potential.
The latest validation of the €uroStars shows that daughters from five-star replacement rams produce 0.14 more lambs per ewe than daughters from one-star rams. That’s an extra 14 lambs for every 100 ewes. There was 1% fewer barren ewes and 1.5% more lambs surving at birth.
Farmers focused on producing lambs for slaughter should look closely at the terminal index, which helps identify rams with stronger potential for growth and finishing performance.
Recent validation shows that lambs from five-star rams are 1.5kg heavier at weaning and finish 15 days quicker than their one-star counterparts. Many commercial flocks will need a balance of both, particularly where some ewe lambs are retained, while the remainder of the flock is bred for lamb output.
The key point is that the €uroStar rating gives farmers a breeding tool that goes beyond visual assessment alone. Physical soundness, health history, and suitability for the flock remain essential, but the genetic information adds another layer of confidence.
A good-looking ram with poor genetic potential may not deliver the performance expected, while a five-star ram combining visual assessment with genetic potential will drive flock improvement.
Finding five-star rams?
The 2026 Sheep Ireland Guide & Directory of Breeders is a practical starting point for any farmer planning to buy a ram. It lists performance-recording LambPlus breeders across lowland breeds and includes hill breeders who meet the relevant criteria at the time of publication.
The directory gives farmers direct access to breeders engaged with Sheep Ireland recording, making it easier to source rams with reliable genetic information.
Ram Search
Farmers can also use Ram Search, available at www.ramsearch.ie, to check the most up-to-date information on individual rams. Ram Search allows users to search by breed, age, star rating, location, Sheep Improvement Scheme eligibility and other criteria.
It can also be used to search a tag of a ram before purchase and check the most recent €urostar evaluation, which is especially important because genetic evaluations can change over time.
For SIS purposes, farmers should always check eligibility on the day of purchase.
The Sheep Ireland Ram sales calendar available at www.sheep.ie, is another useful planning tool. It brings upcoming ram sales together in one place, helping farmers identify sale dates, locations, marts, breed society sales, and catalogue links.
This allows buyers to plan ahead, compare options and avoid leaving ram purchasing until the last minute.
In addition, Sheep Ireland sales provide a focused opportunity to purchase rams that meet high entry standards.
The Sheep Ireland Elite €uroStar Multi-Breed Ram Sale in Kilkenny Mart on Saturday 22 August at 10.30am features rams that must be five-star on either the replacement or terminal index at catalogue printing, genotyped with genomic evaluation, fully parentage verified and physically inspected.
Sheep Ireland’s hill ram sales also offer commercial hill farmers access to genotyped and sire-verified rams from participating hill breeding groups.
This sale take place in Manorhamilton Mart Co Leitrim, on Friday 9 October at 6pm.
A better buying decision
Buying a ram should never be rushed. Farmers should use the Guide & Directory to identify breeders, Ram Search to verify individual animals and the sales calendar to plan where to buy.
By combining these tools, commercial farmers can make better-informed decisions and increase the chances that the ram they buy will deliver real value in the flock.
The message is straightforward: a five-star ram is not just a better-rated animal on paper. He is a practical route to fewer lambing problems, more lambs, faster-finishing stock, and stronger long-term flock performance. For commercial sheep farmers aiming to improve profitability and efficiency, choosing a five-star ram makes sound business sense.
