Good At Finishing? You Need To Be Great!
November, 2024
Beef and wool are better at turning poor-quality feed into product. Cows are great at utilizing poor-quality feed, and Merino sheep don’t require high-quality feed to produce a fine fleece. However, in lamb, you not only need high feed utilization, you also need to convert feed into kilograms of lamb. This hinges on maximizing feed quality, which is determined by pasture composition and subsequent management.
Success in lamb is based on growth rate, which is a subset of feed quality. Given the importance of stocking rate, achieving growth rate can be difficult during lactation due to feed limitations and worm burdens. Mentally, producers need to split breeding and finishing. Breeding focuses on delivering as many lambs per hectare to a finishing system, and using available feed resources to maximize weaning weight.

Finishing is about growth rate. The difference between 175 grams a day and 350 grams a day changes a typical lamb’s turn-off time post-weaning from 60 days (two months) to 120 days (four months). That extra two months adds labour and husbandry costs, which heavily contributes to the cost of production. Another important consideration is that high-growth lambs—whether on grain or grass—have a lower feed conversion ratio, meaning less feed is required to put on a kilogram of live weight.

One of the problems is that there is no set recipe in grass finishing systems. What pasture is best varies with every postcode and environment. We use lucerne, chicory, and clover, but the downside is that if these aren’t managed precisely, they can struggle to persist, making them a high-cost option. You unfortunately can’t just be good at managing finishing pastures; you need to be great. Species selection, weed control, and grazing management must be precise. Those who use these systems effectively run highly profitable lamb operations driven by growth rate. Those who don’t manage them correctly produce slow-growing lambs, making it a high-cost option.
The single biggest opportunity for clients is to become better finishers. You can’t be simply good; you need to be freakishly great.
Labour Efficient Sheep Systems
September, 2023
The average sheep producer is around 64 years old and often struggles to find enough help on the farm.
When we look at the facts on declining sheep numbers, it highlights why many producers are rethinking their operations. For some, sheep are too labour-intensive, and the current lack of strong economic returns may drive them to switch enterprises. The lure of simpler operations, such as beef, is real – especially in regions like New England, where many producers have shifted away from sheep over the past two decades.
However, lamb still has more potential than other major proteins (beef, pork, and chicken) because it faces less competition, but the manner in which we produce them needs to change.
Wool needs to go on a large percentage of Australia’s sheep.
Wool is now a significant cost for sheep producers. The number of available shearers is unlikely to increase, sheep are getting bigger and stronger, and there is no sign that shearing costs will go down.
However, the cost of wool is not just about shearing. Crutching, dagging, and blowfly prevention also take a lot of time each year. We rarely discuss the production losses linked to shearing and other wool-based tasks.
Moving to shedding sheep is appealing, but it requires substantial investment to match the production (growth, fertility) of the Primeline Maternal flock and to reach similar ease of management for drenching and foot health. In our experience, the best shedding sheep still lag behind Primeline Maternal sheep, though we are seeing promising outliers in all traits.
With focused selection pressure and new technologies – such as sexed semen, embryo transfer, and genomics – performance will improve rapidly. We estimate that by 2027, half of our maternal rams will be shedding. Over time, a shedding flock will likely lower production costs significantly.

Many husbandry costs can be removed in seedstock.
‘Training should be so hard the game should be easy’ – from my former rugby days.
The process of testing and selecting seedstock must be relevant to commercial operations, with a focus on reducing labor and costs in lamb production. Unfortunately, much of the past century’s selection happened in “perfect” environments (like show sheds), which did not reflect the real-world conditions faced by most producers.
From the beginning, we aimed to produce seedstock under commercial conditions, at higher stocking rates than many of our clients. Over time, we have experimented with ways to reduce costs by adjusting husbandry processes. Since 2003, we have only summer-drenched mature maternal ewes once (for barber’s pole). In 2023, we decided not to drench any mature ewes at all unless their worm egg count exceeds 1000 during late pregnancy. We recognize this may lower production on average and that some ewes will fall behind, but many others in the same group will maintain strong weaning weights, even with high worm counts. By collecting data in these challenging conditions, we can identify and reward high-performing, low-cost sheep.
A major priority is maintaining single contemporary groups wherever possible. In many stud programs, ewes in poor condition are often given extra feed, leading to artificially high performance results and more expensive sheep. Similarly, simply culling ewes with poor foot structure or lameness helps reduce production losses linked to foot problems.
Ultimately, the seedstock sector needs a rapid shift in thinking because producers bear the cost of inefficient or non-commercial breeding practices. Selecting sheep that thrive in low-cost environments benefits commercial flocks and will be a key factor in driving down the cost of production industry-wide.
How To Get To Shedding: The Best Strategy
September, 2022
Transitioning to a Primeline shedding flock is a common question for many clients and prospective clients. In our experience, moving to shedding within Primeline Maternal flocks usually takes two or three crosses (though some may do it in a single cross).
The key question is how to make this transition quickly while managing compromises along the way. First, note that current shedding sheep lag behind Primeline Maternal sheep for several production traits (such as fertility and growth). Second, shedding sheep generally have lower marbling, which does not align with our broader LAMBPRO breeding goals.

While these factors may influence short-term decisions, the good news is that we already have fully shedding maternal genetics (with no outside breeds) and access to advanced technology (sexed semen, embryo transfer, and genomics). This will accelerate development, and the principles of population genetics will help us deliver improved shedding sheep for our clients.
For those clients with Primeline Maternal ewe flocks looking to start this process, we recommend beginning with the 20% of ewes in your flock that already show some shedding traits. By focusing on that smaller group first, you can refine the genetics before expanding to the entire flock. While the transition market for these ewes may be limited initially, early adopters will likely see high demand once the process is complete.
Market development for Primeline Shedder lambs will continue under the Primeline Maternal brand, working closely with end users to build demand for Primeline Shedder lambs at slaughter.
Primeline Maternal Ewe Market Drivers
October, 2022
Lambpro first marketed clients’ Primeline Maternal ewes in 2006 as part of a branded lamb sale. Since then, ewe marketing has been a key part of Lambpro, as these ewes have formed and entry point for new clients to access genetics without the build up time frame.
Ewe sales have always been cyclical, and that pattern is unlikely to change. One major advantage of a self-replacing system is that you don’t need to buy ewes every year – unlike the traditional first-cross ewe model. As a result, most purchases occur when new clients enter the market, when existing clients rebuild after a drought, or when they expand onto new land.

We often see spikes in demand post-drought; for example, around 2010 and again in 2020. Between these spikes, demand tends to be driven by how land used for sheep competes financially against other enterprises (often wool), along with general changes in farming operations.
A key strength of Primeline Maternal ewes is their solid reputation compared to other composites. We invest significant time and resources into promoting our clients’ ewes, and we will continue to do so in the future.
It’s important to consider ewe lamb sales in terms of cents per kilo (relative to store or slaughter prices) rather than by head count. Over the long term, ewe lambs should return a premium of about $2–$3 per kilogram dressed weight above comparable lambs, adding substantial value to a lamb enterprise with little additional cost.
Labour: The Achilles Heel for Agriculture
September, 2022
Labour shortages are affecting every sector of the Australian economy. From McDonald’s offering a thousand-dollar sign-on fee, to business leaders pleading with the government for improved work visas and migration policies, it’s clear there aren’t enough workers to go around.
The sheep industry is no exception – every link in its supply chain faces chronic labour shortages, from restaurant staff to truck drivers to abattoir workers and shearers. This could become a serious challenge for agriculture in the short to medium term. Meanwhile, sheep operations continue to grow more intensive, with modern management practices adding even more tasks. It’s worth noting that the average Australian sheep farmer is now 64 years old.

By contrast, cropping operations are trending toward higher efficiency, thanks to rapid technology adoption. This has led to fewer labour requirements per hectare. Beef, another major competitor for land, has also made significant changes to reduce labour, with many businesses now running 1,000 cows per worker.
Sheep production needs to adapt by doing more with less: using less feed (through higher stocking rates) and relying on less labour. Two decades of selecting for lower-labour sheep is paying off, and the rising market share of Primeline Maternal sheep reflects their easier management requirements. The move toward shedding sheep aims to further reduce labour demands.
In my view, the future of the sheep industry will be heavily influenced by labour availability, and we’re already seeing its impact on the flock. Simple, low-cost sheep systems consistently come out on top. We remain focused on decreasing the labour needs of our lamb systems to stay competitive and sustainable in this evolving landscape.
