Sheep Farm Management in Australia: Records, Lambing and Profit

Good sheep farm management in Australia comes down to four things: matching the flock to your pasture and rainfall, choosing a clear enterprise (wool, prime lamb or both), tracking lambing percentage from joining to marking to weaning, and having a drought feeding plan before you need it. Records per head and per mob turn those decisions into profit.

Australia runs one of the world's best-known sheep industries, built on pasture rather than pens. Flocks range from a few hundred ewes on a mixed cropping farm to very large Merino stations in the pastoral zone. Whatever the size, the same questions decide the result: how many lambs survive, how much the flock costs to feed through a dry spell, and what each head earns from wool and meat. If you are still at the planning stage, read how to start a sheep farm in Australia first.

Wool, prime lamb or dual purpose?

Your enterprise drives breed choice, joining time, shearing and sale plan. Most Australian flocks fall into one of three models:

Shedding meat breeds such as the Dorper appeal to farmers who want to avoid shearing and crutching, while Merinos remain the backbone of the wool clip. Many farms join part of their Merino ewes to a terminal sire, so they sell both wool and prime lambs.

Tracking lambing percentage properly

Lambing percentage is the number that most often separates a profitable flock from a struggling one. In Australia it is usually counted as lambs marked per ewes joined, so losses between birth and marking are included.

Track it in stages, by mob:

1. Ewes joined: date, ram used, body condition at joining.
2. Pregnancy scanning: empty, single and twin-bearing ewes, so twins can be given better feed and shelter.
3. Lambing: births, deaths and mothering problems in each paddock.
4. Marking: lambs counted at marking, which gives your marking percentage.
5. Weaning and turn-off: lambs weaned, weights, and age at sale.

When you know where lambs are lost, you know what to fix: ewe condition, paddock shelter for twins, predators, or timing of lambing against feed supply. Remember gestation is about 147 days (142 to 152), so plan joining date from the lambing date you want. Our lambing season checklist covers the practical preparation.

Drought and dry-season feeding

Dry seasons are part of farming in most of Australia, so plan before the pasture runs out:

• Set trigger points: decide in advance the feed on offer or condition score at which you start supplementary feeding, sell, or move stock to a containment area.
• Sell early, not late: culls, dry ewes and older stock are the first to go, because selling in good condition beats selling in poor condition at the bottom of the market.
• Protect the core breeding flock: keep the young, fertile ewes you would struggle to replace.
• Feed in containment areas when paddocks are bare, to protect ground cover and soil.
• Weigh and condition score regularly, because it is the only way to know whether the ration is working.
• Water first: check supply and quality every day in hot weather.

Work out your feed budget per head per day and multiply it by the weeks you expect to feed. That single number tells you whether to buy grain and hay, agist, or reduce numbers. More ideas in our drought and dry season herd management guide.

Shearing, crutching and flock health

Wool flocks are usually shorn once a year, with crutching between shearings to keep the breech clean and reduce flystrike risk. Many farmers time shearing around lambing so ewes are either shorn well before lambing or after weaning. Book shearers early, because shearing teams are in demand in the busy season.

Flystrike prevention is a major part of Merino management. Some wool buyers and brands increasingly ask for wool from flocks that are not mulesed, and many breeders are selecting for plainer-bodied sheep that are less prone to breech strike. Talk to your vet and wool buyer about the approach that suits your flock and market.

For flock health in general:

• Worms: monitor with faecal egg counts rather than drenching on a fixed calendar, and ask your vet about drench resistance on your farm.
• Vaccination: follow the programme your vet recommends for your district.
• Lameness and footrot: inspect feet, isolate affected sheep and get a diagnosis.
• New stock: isolate purchased animals before mixing them with your flock.
• Treatment records: note product, date and animal or mob, so you respect withholding periods before sale.

Identification and traceability

Australia has a national system for identifying livestock and tracing their movements. Sheep and goats must carry approved identification and movements must be recorded according to the rules in your state or territory. Requirements are changing, including the move to electronic tags, so check the current rules with your state agriculture or primary industries department before you buy tags or move stock. Your own management records sit on top of that: the official tag proves where an animal has been, your records tell you what it is worth to you.

Running the records in practice

A flock is easier to manage when the numbers live in one place instead of notebooks in the ute. On the Throf platform each sheep has a record with its tag number, breed, sex, birth date, dam and sire, weights and paddock group, and RFID tags are supported. You can log joining, scanning results, lambing and twins, weaning and treatments, and receive health alerts and reminders.

Throf works in English, Arabic and French on a phone in the paddock, a laptop in the office or a tablet in the shed. Expenses and sales give you cost per head and net profit, and Excel reports cover lambing, weights, health and finance. If you employ a manager or casual staff, each person gets an account with permissions, so they record work without seeing what they should not.
