I’ve lost count of how many glossy brochures I’ve seen claiming you need a laboratory-grade nutritional plan and a pallet of expensive, branded supplements to get through the season. It’s enough to make you want to head straight to the pub. Most of these “experts” wouldn’t know a hungry ewe from a hole in the ground, and they certainly don’t account for a wet February or a field that’s turned into a bog overnight. If you’re looking for a way to overcomplicate how to feed ewes before lambing just to impress the neighbors, you’ve come to the wrong place. In my experience, if you start chasing every new additive on the market, you’ll find your margins disappearing long before the first lamb hits the ground.
I’m not here to sell you a bag of anything. What I want to do is talk about the reality of the situation: the grass, the weather, and the actual cost of the feed in your troughs. I’ll tell you exactly where I’ve wasted money on fancy concentrates that did nothing but fatten the salesman, and how to focus on the essential nutrition that actually translates into heavy lambs and healthy mothers. This isn’t about perfection; it’s about making sure your hard work doesn’t end up as nothing more than expensive manure.

The Expensive Mistake of How to Feed Ewes Before Lambing

I’ve seen it a dozen times: a young lad or a new tenant gets a bit of extra money in the bank and decides the best way to use it is by buying every shiny bag of concentrate on the market. They think they’re “optimising nutrition,” but they’re usually just throwing money into a trough that the sheep aren’t even using properly. The real mistake isn’t failing to feed; it’s feeding without looking at the ground first. If you start supplementing forage with concentrates when the grass is already coming on thick and lush, you aren’t building a lamb crop—you’re just building fat, and fat sheep are expensive sheep that don’t lamb well.
The goal isn’t to make them heavy; it’s to get the condition right. I spent far too many years chasing high numbers by overfeeding, only to find myself staring at a flock of ewes that were too fat to move and too weak to lamb. You have to focus on managing ewe body condition score with a bit of discipline. If you miss the window where they actually need that extra boost, you’re just burning cash. You want them ready, not rotund.
Flushing Ewes for Higher Lambing Rates Without Wasting Feed

Now, everyone loves to talk about flushing ewes for higher lambing rates like it’s some magic trick you can buy in a bag of pellets. They tell you to ramp up the energy three weeks out and suddenly you’ve got twins across the board. But if you’re doing that on ground that’s already running lean, you’re just burning cash for a marginal gain that might not even show up in the pens. I’ve seen men spend a fortune on concentrates only to find their ewes have put on so much condition they’re struggling to walk, let alone lamb well.
The real work is in managing ewe body condition score long before you even think about the supplement bin. You want them coming into the final stretch with enough cover to weather a bad spell, but not so much that they’re wasting energy storing fat. It’s a narrow margin. If you get the plane right—balancing the grass quality with just enough supplemental feed to nudge the ovulation rate—you’ll see the difference in the lamb numbers. If you don’t, you’re just feeding the soil and the salesman, not your bottom line.
Managing Ewe Body Condition Score to Protect Your Margins

You can spend all the time you like reading about the latest grain mixes, but if you aren’t managing ewe body condition score with a bit of common sense, you’re just throwing money into a trough. I’ve seen plenty of lads walk into lambing season with ewes that look like they’ve been through a hedge backwards—too thin to carry a healthy lamb, or worse, so fat they’ll be having calving difficulties before the first frost. A cowy, fat ewe is a liability; she’ll have a poor temperament and a high chance of metabolic issues. On the flip side, a thin ewe is a wasted slot in your system. You aren’t just feeding an animal; you’re protecting your margin for the next twelve months.
When it comes to late gestation sheep feeding strategies, the goal isn’t to make them heavy, it’s to make them efficient. As the lambs grow in that final stretch, the ewe simply runs out of room in the rumen. This is where most people panic and overdo the concentrates, but you have to be surgical about it. If you get the condition right in the autumn, you won’t be scrambling to fix broken bodies come March.
Supplementing Forage With Concentrates What Actually Stays in the Gut
Now, here is where most people go wrong and start throwing expensive bags of pellets at the flock because they’ve read a glossy brochure. You can’t just replace good grass with concentrate and expect the same result. When you’re supplementing forage with concentrates, you have to remember that a sheep’s rumen isn’t a bucket you just pour stuff into; it’s a living, breathing engine. If you transition too fast or rely too heavily on grain to make up for poor pasture, you aren’t just feeding them; you’re playing a dangerous game with acidosis. I’ve seen enough sheep stumble around with a bloated belly to know that cheap feed often becomes the most expensive mistake on the farm.
The goal isn’t to turn your ewes into fat little things, but to ensure they meet their pre-lambing nutritional requirements without breaking the bank. I prefer to use concentrates as a precision tool—something to bridge the gap when the grass quality dips or when the lambs are getting big in the womb. It’s about balance. If you’re looking at late gestation sheep feeding strategies, remember that the energy needs are spiking, but so are the risks. Keep the concentrate levels steady, keep the mineral mix right, and for heaven’s sake, don’t forget that the best supplement is still a decent bit of forage.
Late Gestation Sheep Feeding Strategies That Save Your Lambs
Once you hit that final month, the game changes entirely. You aren’t just feeding for the ewe anymore; you’re feeding for the lambs that are taking up more and more room in the womb. This is where most people trip up by thinking more is always better. If you go too heavy on the concentrates too early, you’re just asking for abomasum displacement or a ewe that’s too fat to get through a difficult birth. The real trick with late gestation sheep feeding strategies is understanding that the lambs’ demand for energy spikes right at the end, but the ewe’s ability to process it is limited by how much space is left in her gut.
I’ve seen too many lads try to fix a poor season by throwing bags of pellets at the problem in March. Instead, focus on the quality of the forage. If your grass is heading off and getting woody, you need to be supplementing forage with concentrates just enough to bridge the gap, not to replace the diet. It’s about maintaining that steady trickle of energy. If you get the nutrition right now, you aren’t just saving the lambs; you’re ensuring the ewe actually has the strength to stand back up and get back to grazing once the job is done.
Five Things That Actually Matter When the Feed Bill Starts Climbing
- Stop looking at the bag and start looking at the field. If your pasture is nothing but old, woody stems and no decent clover, all the concentrate in the world won’t fix a lack of protein. You can’t feed your way out of a bad sward without bleeding cash.
- Watch the teeth, not just the belly. I’ve seen many a farmer try to push a hard ration on an older ewe that’s lost her ability to chew properly. If she can’t process the forage, you’re essentially just throwing money into the muck pile.
- Consistency is more important than quantity. I’ve learned the hard way that swinging from “feast” to “famine” by dumping feed only when you see a rib will mess with their gut flora and leave you with nothing but scours and empty pens.
- Mineral lick is cheap insurance, but don’t expect it to do the heavy lifting. It’s there to fill the gaps, not to replace a decent diet. If you’re relying on a lick to fix a nutritional deficit, you’ve already lost the margin.
- Keep a close eye on the water troughs. You can provide the finest meal in the county, but if that water is fouled or the trough is frozen, she won’t eat. A thirsty ewe is a stressed ewe, and a stressed ewe doesn’t make a profit.
The Bottom Line Before You Reach for the Feed Bag
Don’t start throwing expensive concentrates at a hungry flock just because the calendar says it’s time; if the ground is soaked and the grass is poor, you’re just throwing cash into a hole that won’t fill up.
Watch the body condition, not the scale—a ewe that looks “right” can still be running on empty, and a ewe that’s too heavy is just a walking way to lose money on lamb vigor and ease of lambing.
Every kilogram of feed you put in the trough needs to be measured against the lamb crop it produces, because if you aren’t seeing more lambs or heavier lambs, you aren’t “feeding,” you’re just subsidizing the feed merchant.
The Bottom Line Before the Lambing Pens Open
At the end of the day, feeding ewes isn’t about following a fancy nutritional chart printed by a grain salesman; it’s about reading your fields and your flock. You’ve looked at the body condition scores, you’ve balanced the concentrates against what the grass is actually giving you, and you’ve made sure those late-gestation ewes aren’t running on empty. If you’ve done that, you’ve protected your most vital assets. Remember, every pound you spend on feed needs to be an investment in a lamb that actually makes it to the market, not just a way to fill a rumen with expensive waste. Keep your eyes on the cash flow and your hands on the ewes, and you’ll avoid the kind of nutritional debt that takes years to pay off.
There will always be a new supplement or a “miracle” mineral lick being pitched at the mart, but don’t let the noise distract you from the basics. Farming is a game of margins, and those margins are won or lost in the quiet months of preparation before the first lamb hits the ground. It’s easy to get caught up in the excitement of a new season, but stay steady and trust the data you’ve gathered from your own acres. You can’t control the weather or the market prices, but you can control how well you prepare your stock to face them. Do the work now, so you aren’t left staring at an empty bank account and a flock of weak lambs come spring.
Frequently Asked Questions
If the ground is too wet to get the sheep out on good pasture, how much concentrate am I actually going to need to bridge the gap without making them fat as pigs?
If the ground’s a bog, you aren’t just feeding them; you’re managing the damage. You can’t just dump grain in the trough and hope for the best, or you’ll have fat ewes and a ruined pasture. Aim for a steady 300g to 500g of concentrate to bridge the gap, depending on how much grass they’re actually getting. Watch the condition closely; if they start looking like they’ve been sitting on a cushion, pull it back immediately.
At what point does adding more feed stop being an investment in the lamb and just become a way of throwing money into a trough?
You hit the wall the moment you stop seeing a rise in lamb weight and start seeing nothing but fat cover on the ewe. If you’re pouring concentrates into the trough and your BCS is climbing but your lambing percentage isn’t budging, you aren’t investing; you’re just subsidising the sheep. Once the ewe is “well-covered,” any extra grain is just expensive fuel for making her too fat to lamb well. Watch the margins, not just the trough.
How do I tell the difference between a ewe that's just a bit thin and one that’s actually struggling to keep up with the lamb growing inside her?
It’s the difference between a hard winter and a failing engine. A thin ewe is usually just “tucked up”—she’s lost her cover, but her eyes are bright and she’s still moving with purpose. A ewe struggling with the lamb is different; she looks hollowed out, even if the forage is decent. Look at the spine and the pelvis. If she’s lagging behind the flock and looking “stale” or lethargic, she’s not just thin—she’s being raided from the inside.
