Dairy farm: a cow is milked 305 days and eats 365

“One hundred and twenty cows, seven hundred and thirty-two thousand litres a year, revenue of almost ten million. And fifty-seven thousand nine hundred and fifty hryvnia a month in hand. For four years I thought milk was simply that kind of business: big turnover, pennies left over” — that is how Vitalii Kravets, owner of a dairy farm in the Cherkasy region, opened the conversation.

If you keep a milking herd, you have already said this to yourself. The tanker takes away tonnes, the processor pays on time. And at the end of the cycle what is left is a sum that would not even buy a decent tractor.

The cause is almost always the same. The calculation holds a cost per litre, and it looks like a property of the farm. In reality it is the result of a division in which every day the cow ate without being milked has disappeared.

We break the farm down into two units: the cow and one of her days. And we get to why 1 857 600 ₴ of spending on animals without milk is 2.67 times more than the annual profit.

Vitalii's path: from six cows to a hundred and twenty

Vitalii started with six cows in his father's shed. He milked them himself, handed the milk to a dealer by the roadside and wrote it down in a notebook: this many litres, this much for feed, the difference is mine.

Over twelve years the herd grew to a hundred and twenty head, a milking parlour appeared, two stockmen, a livestock specialist and a part-time bookkeeper. Along with them the feel for the figures disappeared: there were twenty times more cows, revenue followed them up, and the money in his pocket stayed almost the same.

“When there were six cows, I knew every one of them by name and I knew how much each gave. Now there are a hundred and twenty, and ask me how many of them are not being milked at all this week. I will give you a rough number. But paying for their feed — that I do exactly.”

Why “a hundred and twenty cows” says nothing about the cost of a litre

A litre is what you get paid for. But a cow does not give a litre, she lives through a day: she eats her ration, takes up space, needs light, water and muck removal. You always pay for the day, and a litre does not always come out of that day.

Because of this, every calculation “per litre” has a trap in it. The numerator holds all the farm's days, and the denominator only those that gave milk. And when the second group is noticeably smaller, the number starts lying by more than pennies.

A cow-day — that is the real unit of account

A cow lives on the farm for 365 days. She is milked for 305. The remaining 60 days she stands dry: she eats, drinks, lies down, prepares for calving — and gives not a single litre.

Put those two numbers side by side: 365 days of costs against 305 days of income. Sixty days out of every cow's year do not exist in the calculation — but they do exist in the barn, and the feed for them is written off exactly like the feed for any other day.

One cow's year: 305 days of milking and 60 days dry

The first thing Vitalii did was write out one cow's year as two separate periods. Not by month and not by herd, but by one animal and all her days.

Period	Days	Feed per day	Feed for the period	Milk, l
Lactation	305	85 ₴	25 925 ₴	6 100
Dry period	60	48 ₴	2 880 ₴	0
Total	365	—	28 805 ₴	6 100

The row with a zero in the last column is the main one in this article. Feed in the dry period is cheaper: 48 ₴ against 85 ₴, because the ration is different, without concentrates for a high yield. But it is not nil, and there is no milk out of it at all.

Two figures for feed per litre — 4.25 ₴ and 4.72 ₴

Vitalii counted it this way: 25 925 ₴ of feed over the lactation divided by 6 100 l gives 4.25 ₴ of feed in a litre. He knew that number by heart and put it into every conversation with the processor.

The right way is different: all 28 805 ₴ of feed for the year divided by the same 6 100 l gives 4.72 ₴. Adding the dry period produced no more milk, but it did produce more feed. The first number describes a cow in milk, the second a cow on the farm. Only the second is any use for the price of a litre.

Why the 0.47 ₴ difference is exactly the dry-period feed

Between 4.72 ₴ and 4.25 ₴ lies 0.47 ₴, and that is not a rounding error. Divide the 2 880 ₴ of dry-period feed by the 6 100 l of yield — you get the same thing.

It reads like this: every litre sold carries almost half a hryvnia of feed eaten on the days when the milking machine was never attached to that cow.

The calculation Vitalii lived with for four years

Now the farm's year in full. A hundred and twenty cows at 6 100 l give 732 000 l, the processor pays 13.20 ₴ a litre — revenue of 9 662 400 ₴. And here are the costs, with a column added that Vitalii's reports never had.

Item	₴/year	Gives milk
Feed for the milking herd (305 × 85 ₴ × 120)	3 111 000 ₴	yes
Feed for the dry cows (60 × 48 ₴ × 120)	345 600 ₴	no
Rearing heifers (36 × 42 000 ₴)	1 512 000 ₴	no
Wages	2 040 000 ₴	yes
Veterinary care and insemination	468 000 ₴	yes
Electricity, water, fuel	612 000 ₴	yes
Depreciation and equipment repairs	528 000 ₴	yes
Other	350 400 ₴	yes
Total	8 967 000 ₴	—

Cost per litre: 8 967 000 divided by 732 000 is 12.25 ₴. Against the price of 13.20 ₴ that leaves 0.95 ₴ a litre, and across the whole yield 695 400 ₴ a year, or 57 950 ₴ a month. Profitability 7.20%.

There is not a single error in this calculation

The processor's invoices, the bank statements, the feed delivery notes — everything balances to the hryvnia. 0.95 ₴ multiplied by 732 000 l gives exactly 695 400 ₴, with no rounding at all. The cost of 12.25 ₴ is an exact number too, not an estimate by eye.

That is precisely what makes it dangerous: correct in every figure and at the same time no answer to the question of what the farm is paying these 8 967 000 ₴ for. Two items are marked “no”, and together they come to 1 857 600 ₴ — more than the wages of everyone on the payroll.

“They showed me that column where it said yes or no, and at first I said it was nonsense: my whole farm gives milk. Then I counted how many head in the barn are not being milked right now. It came out at almost every fifth one.”

How it was counted before

The bookkeeping Vitalii lived in through those years will be recognised by any farm that grew out of a few cows in a shed.

• Feed was written off as a single line for the herd. A lorry of compound feed arrived — it went into the farm's costs, with no breakdown by group.
• The dry cows were not separated into an accounting group of their own. The livestock specialist had them on a list; the costs did not.
• Cost was counted over the lactation. 4.25 ₴ of feed per litre — and that number went into every conversation about price.
• Heifers were treated as replacement, not as a cost. “They are our future herd, aren't they” — instead of a sum per head.
• Days were not counted at all. Everything was measured in litres and head, and a cow-day was never a unit anywhere.
• Herd replacement was planned by feel. A cow was culled when it became obvious it was time, not against an annual norm.

Not one of these six problems is a livestock problem. The cows are healthy, the ration is balanced, the yields are at the district level. All six sat in the bookkeeping — and nobody looks into the bookkeeping on a farm, because there is always more important work there.

The first hidden item: 345 600 ₴ of feed with not a litre under it

Take the dry-period row across the herd. Sixty days at 48 ₴ for a hundred and twenty head — 345 600 ₴ a year. Feed eaten by animals that give nothing during that time.

Compare it with the profit: 345 600 ₴ against 695 400 ₴ — almost half of everything the farm earns in a year goes into the troughs of a group with zero yield. Per litre that is the same 0.47 ₴, which is exactly half of the 0.95 ₴ margin.

Half the earnings from every litre are taken by the days on which that litre was not milked. Not theft, not losses of stock, not a low processor price — simply feed that was not in the calculation.

The second hidden item: 36 heifers and 730 days to the first litre

The second item is four times bigger than the first, and it is hidden deeper still, because it lies outside the year. Before those 365 days of a milking cow there were another 730, when she was growing and was not milked for a single day.

The herd does not stand still: cows age, their yield drops, they get culled. For the farm to hold at a hundred and twenty head, 30% of the herd has to be replaced every year — that is 36 heifers. Rearing one of them to her first calving costs 42 000 ₴. Together that is 1 512 000 ₴ a year, and not one of them is milked in that year.

Why 42 000 ₴ a head is 1 750 ₴ every month

Forty-two thousand over two years looks like a one-off purchase, and that makes it easy to miss. Divide it by twenty-four months: 1 750 ₴ every month for every head that is not yet being milked.

That is exactly how it leaves the account — monthly, in small amounts, together with the milking herd's feed and therefore unnoticed. Per litre of milk those 1 512 000 ₴ work out at 2.07 ₴: more than half the price of a litre and twice the margin on it.

“I did not count the heifers as a cost at all. They are mine, they were born here, they grew up on my hay — what kind of cost is that? And then I saw one thousand seven hundred and fifty hryvnia a month per head and multiplied it by thirty-six. And I realised that for four years I had been keeping a second farm in the barn, one that sells nothing.”

1 857 600 ₴ against 695 400 ₴ of profit

We add the two items together: 345 600 ₴ of dry-period feed plus 1 512 000 ₴ for the heifers — 1 857 600 ₴ a year. Adding up here is both allowed and necessary: both sums are costs for animals that give not a single litre in this period.

The farm's profit for the same year is 695 400 ₴. The unproductive costs are 2.67 times bigger than it. That is, for every hryvnia that reached the owner's pocket, the farm spent 2.67 ₴ on animals without milk.

Why 2.17 and 2.67 are two different multiples

There are two multiples of the profit in this article, and they must not be mixed up. 2.17 is the heifers only: 1 512 000 ₴ against 695 400 ₴. 2.67 is the heifers together with the dry-period feed: 1 857 600 ₴ against the same 695 400 ₴.

The first answers the question “what does replacing the herd cost compared with the earnings”. The second — “how many animals is the farm paying for not milking right now”.

Why 1 857 600 ₴ cannot be subtracted from the profit

The commonest mistake after a calculation like this is to add 1 857 600 ₴ to the costs or subtract it from the profit and get a minus. That must not be done.

This money already sits inside the 8 967 000 ₴. The dry-period feed stands as a separate row in the table, and the rearing of heifers does too. The farm's costs were and remain 8 967 000 ₴, the cost per litre 12.25 ₴, the profit 695 400 ₴. Nothing has been added and nothing has disappeared.

What is the figure for, then? To see the price of the unproductive days. As long as the dry period and the heifers live inside a shared line called “feed”, they look free. The moment they get a sum of their own, you can see where the cheapest reserve on this farm lies.

“For four years I was looking for somewhere to save: I haggled over compound feed, changed the diesel supplier, thought about cutting a stockman. And the most expensive thing I had was the thing I was not counting at all.”

The dry period is not downtime and not the owner's mistake

Care is needed here, because it is easy to draw a false conclusion from the previous sections: get rid of the dry period and milk the cow all year round. It does not work that way.

• The udder has to rebuild its tissue. Without the pause the next lactation will be lower, and you will lose more litres than you gained.
• The calf takes everything in the last third of gestation. A cow cannot feed the foetus and hold a high yield at the same time.
• The dry-period ration prepares the cow for calving. Mistakes here come out later as mastitis, paresis and hard calvings.
• A short rest costs dear at calving. The vet and a lost calf cost more than the feed eaten.

The question is not about taking the dry period away, but about it being a row in the cost of a litre — and about its length being the owner's decision rather than “the way it turned out”.

A scenario: a dry period of 45 days instead of 60

Vitalii's sixty days were there not out of a calculation but out of habit: that is how his father did it, that is how the neighbours do it. Forty-five days is normal practice for a healthy cow in good condition. Here is what those fifteen days change.

Indicator	Dry period of 60 days	Dry period of 45 days
Days of lactation	305	320
Yield per cow, l	6 100	6 295
Herd milk, l	732 000	755 400
Herd feed, ₴/year	3 456 600 ₴	3 523 200 ₴
Profit, ₴/year	695 400 ₴	937 680 ₴

No new cow, no new hectare. The same farm, in which fifteen days out of every cow's year have moved from one column into the other.

Why the tail of the lactation gives 13 l, not 20

It is easy to paint yourself a gain three times bigger than the real one here. Those fifteen days are not the middle of the lactation but its tail: a cow there gives 13 l a day, not twenty as at the peak.

We count by the tail: 15 days at 13 l is 195 l from a cow, and across a hundred and twenty head 23 400 l for the herd. It is out of those 195 l that the yield grows from 6 100 to 6 295 l, not out of an optimistic average.

The net gain: 308 880 ₴ of revenue minus 66 600 ₴ of feed

The milk from those days goes at the usual price: 23 400 l at 13.20 ₴ — 308 880 ₴. But the feed gets dearer too: a cow that is being milked eats 85 ₴ worth instead of 48 ₴. The difference of 37 ₴ a day, multiplied by 15 days and 120 head, gives 66 600 ₴.

The net gain: 308 880 minus 66 600 is 242 280 ₴ a year. The profit rises from 695 400 ₴ to 937 680 ₴, that is, by 1.35 times, and the gain itself is 34.8% of what the farm has now. On the existing herd and in the existing barn.

Why 13 l and 13.20 ₴ have nothing in common

Two numbers starting with thirteen stand in two neighbouring paragraphs, and that is a coincidence, not a slip of the pen. 13 l is the cow's yield in the tail of the lactation, litres a day. 13.20 ₴ is the price the processor pays for one litre, hryvnia a litre.

One does not follow from the other: the first is measured in litres a day, the second in hryvnia a litre.

“Two hundred and forty-two thousand for fifteen days that I did not add to anybody and did not take away from anybody. No new cow, no new hectare. The cow simply went dry when I decided it, not when the calendar in my head did.”

What changed after the recalculation

Three changes came out of it in the paperwork. Feed began to be written off to two groups separately — the milking one and the dry one. The heifers got a row of their own with a sum per head and per month. And a cow-day became a unit of account: the report shows how many days in the herd are being milked and how many are just eating.

• The dry-period feed stopped being invisible. 345 600 ₴ a year and 0.47 ₴ in every litre — that is a row now, not part of a shared lorry of compound feed.
• Herd replacement got a price. 36 heifers at 42 000 ₴, which is 1 750 ₴ a head every month and 2.07 ₴ out of every litre sold.
• The length of the dry period became a decision. 45 days instead of 60 give 23 400 l and 242 280 ₴ — a gain of 34.8% on the profit without a single new animal.
• The cost of a litre is counted over all the days. 4.72 ₴ of feed instead of 4.25 ₴ — and the conversation with the processor about price became a conversation with numbers rather than with feelings.

No new equipment, no bigger herd and no price increase were needed. What was needed was to see a cow-day as a row with a price of its own.

What to take from this for yourself. If your income is produced by a living organism — a cow, a sow, a hen, an orchard, a pond — then between the cost and the revenue there is always a stretch of time when the cost is already there and the revenue is not yet. That time has to be counted in days and in money, otherwise it settles into the unit cost and makes it prettier than it is. Divide all the costs by all the days, not by the ones that produced the product. Then count separately how many animals or plants you are paying right now for giving nothing, and put that sum next to the annual profit. If it turns out to be the bigger one — you have found where the cheapest reserve on your farm lies.

What to calculate first

• Count the days, not just the litres. 365 days of costs against 305 days of income — all the arithmetic starts from that pair.
• Work out feed per litre in two ways. 4.25 ₴ over the lactation and 4.72 ₴ over the whole year; put the second one into the price of a litre.
• Give the dry group a feed row of its own. 345 600 ₴ a year is invisible as long as compound feed goes in one line for the whole herd.
• Put the rearing of heifers into costs, not into replacement. 36 head at 42 000 ₴ is 1 512 000 ₴, 2.17 times more than the annual profit.
• Convert the cost of a heifer into a month. 1 750 ₴ a head every month is clearer than 42 000 ₴ over two years, because that is how it actually gets paid.
• Compare the unproductive costs with the profit, not with the revenue. 1 857 600 ₴ against 695 400 ₴ gives 2.67 times; against the revenue it would look like a trifle.
• Check where the length of your dry period came from. If it came out of tradition rather than a calculation, there are 15 days of lactation and 242 280 ₴ a year lying in there.

The money does not vanish — you simply do not see it

People think that on a dairy farm everything is decided by three things: the breed, the ration and the processor's price. You really cannot start without them. But the earnings are decided by a fourth — how many milking days got the costs of all the days the farm paid for.

A hole like that does not close by itself and will not show up in the bottom line: the line totals the year, while the money burns in those sixty days and those two years that never existed in the calculation “per litre”. But the moment a cow-day gets a price, the main thing becomes visible: 7.20% profitability describes neither the milking herd, nor the dry group, nor the heifers in the far barn. It is a proportion in which a business that sells milk and a business that is only getting ready to sell it have been mixed together.

How to see this on your own farm

Everything described above rests on one kind of bookkeeping: not the herd as a single figure, but a group as a line. As long as the cost of a litre comes from dividing all the costs by the whole yield, you can see neither that 60 days of dry period give nothing nor that a heifer eats on credit for two years. When the same data is collected automatically, you can see what a cow-day costs and not just a litre, which is exactly why small and medium business owners use Finmap: to see the financial picture instead of guessing at it.
