Every serious production budget in South Africa carries a line for crop insurance now. Hail can flatten a season in ten minutes, so nobody argues. But a feed budget for dairy farms that carries a line for losses in the feed shed? Pretty rare. And feed is the biggest bill on most dairies and feedlots.
Why a feed budget for dairy farms needs a risk line
Feed losses don’t hit like hail. They leak. A few percent at a time, every day: spoiled silage at the face, meal blowing off in the wind, overfed pens, refusals on the heap, loads mixed by eye. Nobody sees it all at once, so nobody budgets for it.
The fix isn’t complicated. Put feed risk in the budget as a number, same as the insurance premium. Once it’s on paper, you can manage it.
Step 1: Put a Yearly Price on Shrink and Refusals
Start with what you bought or harvested versus what the herd actually ate. The difference is shrink. Split it into rough buckets:
- Storage loss: the silage face, bunker covers, effluent, rats and birds in the concentrates.
- Handling loss: spills at loading, wind on dry ingredients, overfilling the mixer.
- Feeding loss: refusals, sorting at the bunk, feed pushed out of reach.
Rough numbers are fine. Say a farm buys R4 million of feed a year and loses 8%. That’s R320,000, and it’s often more than the crop insurance premium. Write that figure down and set a target to bring it down.
Step 2: Set a Forage Reserve Trigger
With forecasters talking about a drier season, the next risk is running short. A forage reserve trigger is one simple rule in the budget: “When forage on the farm drops below X days of feeding, we buy, contract or change the ration.” Work out daily tonnes fed per group, divide stock on hand by that, and check the number every week.
That trigger turns a crisis into a planned purchase. Bought forage is cheapest early, before the whole district is chasing the same bales.
Step 3: Make the Bunk Match the Feed Budget
A feed budget for dairy farms assumes a ration. If the loads leaving the yard don’t match it, the budget is fiction. This is where weighing pays for itself. When every ingredient is weighed into the mixer and every pen’s delivery is recorded, you can compare formulated against actual every day, not at year-end.
Most guys find the biggest gap isn’t price. It’s quantity. An extra bucket of meal here, a heavy hand on silage there. Accurate weighing on a vertical TMR mixer, like the LEO scale systems on mixers like our VT twin-auger range, gives the feeder a target for every ingredient and leaves a record the manager can check.
Step 4: Check It Monthly, Not Yearly
A budget only works if you look at it while there’s still time to do something. A monthly check should cover:
- Tonnes fed per group against budget.
- Cost per animal per day, and per litre of milk or kilogram of gain.
- Days of forage on hand against the reserve trigger.
- Refusals and shrink estimates.
When something drifts, you can fix the ration, renegotiate supply or adjust stock numbers before the bank statement makes the decision for you.
Where the Money Actually Goes
Most farms doing this for the first time find three things. The shrink number is bigger than they thought. The forage reserve is thinner than the manager thought. And the difference between loads is bigger than anybody wants to admit. None of that is in a crop insurance policy. All of it can cost as much as a bad harvest.
Checklist for the 2027 Budget
- Add a “feed risk” line equal to estimated shrink plus a forage shortfall allowance.
- Set a forage reserve trigger in days of feeding.
- Weigh ingredients and record deliveries per pen or group.
- Compare actual against formulated every month.
- Revisit the budget when the weather outlook changes, not just at year-end.
Mistakes That Wreck a Feed Budget
- Only looking at purchase price. Feed lost in storage and at the bunk is part of what you pay per kilogram actually eaten.
- Ignoring the season. Shrink usually runs higher in hot, wet months and when silage faces are opened too wide.
- Treating the reserve as optional. When the dry season shows up, the cheap bales go first.
A budget that names these risks gives you room to act early instead of scrambling late.
Final Truth
Insurance covers the crop in the field. Weighing and good habits cover the feed in the shed. Putting feed losses in the budget, and measuring them with weighed loads, is about the cheapest insurance a livestock operation can buy. Looking at your mixing setup before next season? Have a look at the LEO product range or talk to your local dealer.
Frequently asked questions
How much feed shrink is normal?
It varies widely by storage and handling. Well-managed silage bunkers and covered concentrate storage keep losses low, while open stacks, uncovered meal and loose loading habits push them much higher. The useful number is your own: measure purchases and harvest against what the herd ate over a few months, then set a realistic reduction target for the next season.
Should the feed budget sit with the nutritionist or the manager?
Both. The nutritionist sets the ration and expected intake. The manager owns the costs, the forage reserve and the monthly review. Share one spreadsheet so both are working from the same numbers, and meet monthly to discuss variances.
What if the forage reserve trigger is hit early?
Treat it as planned, not as an emergency. Options include buying forage, contracting supply, adjusting the ration toward available ingredients, or reducing stock numbers. The earlier the trigger fires, the more options remain open and the lower the cost tends to be.
Does weighing really change behaviour on the farm?
In most cases, yes. When feeders know loads are recorded and reviewed, they load to target. Managers also gain the evidence they need to correct habits without guesswork.
