Closeout & Cost-of-Gain Summariser

From a pen's feed, weight, treatment and market data it drafts a plain-English closeout — cost of gain, ADG, feed conversion, days on feed and margin — with an exit-timing recommendation, for the owner or business manager to approve before it goes out.

FIG. 1

The live demo, running on fabricated data. Open it to step through the full flow — every output is shown for a person to approve before anything happens.

How it would work

Reads the pen's own feed, weight, treatment and market data, computes cost of gain, ADG, feed conversion, days on feed and margin per head, drafts the closeout in plain English with an exit-timing line, and lays it all out for the owner or business manager to approve before it reaches the cattle owner.

Input 01
The pen's numbers, where they live

Entry and exit liveweights from the scale system, total feed fed on a dry-matter basis and ration cost from the mill log, pulls and mortalities from the chute book, and the dressing percentage, HSCW and current over-the-hooks grid from the market inputs.

Agent 02
Computes, then drafts

Works out ADG, feed conversion on a dry-matter basis, cost of gain in dollars per kilogram of gain, days on feed and margin per head, then drafts a readable closeout that reads those figures against the pen's MSA target and ends with an exit-timing line.

Output 03
A draft, with the figures shown

A complete closeout with every figure and the exit-timing recommendation laid out for the owner or business manager to sanity-check against what they know about the pen, then approve, edit or hold before it goes to the cattle owner.

Where it works well

It does the weekend of reconciliation in seconds, while the hold-or-ship call still matters.

  • Done by hand it is a weekend of spreadsheet work per pen — and the closeout lands after the exit decision it was meant to inform, not before.
  • Best for an operation turning off multiple pens against MSA grids, where cost of gain and exit timing drive the margin: own cattle or custom-fed.
  • At a closeout per pen across the turnoff, the recaptured time goes back into the yard and the next pen's ration call, not into reconciling four systems by hand.

The slow, invisible cost of a closeout is the reconciliation — feed sits in the mill log, weights in the scale system, pulls in the chute book and the grid price in an email, and someone pulls them into a spreadsheet to work out what the pen cost to put on weight. By the time it is done, the cattle have often already shipped by default.

Where it works badly

It is confidently wrong when an input is wrong — it writes a clean, professional closeout around a bad number.

  • It does the arithmetic on the figures it is given; it cannot know the feed total is short a delivery or the grid is last week's. A wrong input produces a wrong margin that looks right.
  • The margin per head is only as good as the feeder-cattle purchase cost behind it — that is the dominant cost, and if it is approximate the margin is approximate, however precise it looks.
  • The exit-timing line projects forward on assumptions about gain and the grid holding; if the market moves or the pen stops gaining, the window it drew is stale.
The honest test

If you cannot say, looking at a finished closeout, which mill-log feed total and which grid price each figure was computed from — this tool has made your closeout faster, not your hold-or-ship call safer.

Feed the wrong ration cost per tonne, a stale grid price, or a mortality the chute book never recorded, and it drafts a tidy closeout with a cost of gain and a margin that read as trustworthy precisely because the prose is clean. That is the trap.

What it doesn't do — and shouldn't

It drafts the closeout. A person approves it. That boundary is deliberate.

WHAT IT DOES
Shows the inputs each figure was computed from — feed total, ration cost, grid price, weights
Lays out cost of gain, ADG, feed conversion, days on feed and margin per head with its working
Frames the exit-timing line as a recommendation, against the current grid and the pen's MSA target
WHAT IT WON’T
Send the closeout to the owner or cattle owner on its own
Decide whether to hold or ship the pen
Certify the margin or the carcase value as final

A closeout is the account a feedlot gives of how a pen performed and what it cost — and for custom-fed cattle it is the account given to someone else's money. A wrong cost of gain or margin misreads the pen's economics and, sent to a custom-feeding client, carries the operation's name to a wrong number. The owner or business manager stays on the decision because the consequence — and the client relationship — lands on them, not the tool.

The real first job

The numbers usually do not live in one place — feed in the mill log, weights in the scale system, pulls in the chute book, the grid in an email — and the ration cost and the feeder-cattle buy-in are the figures most often held loosely. Getting those inputs captured cleanly and reconciled per pen is usually the real first job — larger and more valuable than the drafting layer on top. Once the inputs are clean, every closeout after that is faster and right by default.

Right fit if…
You close out multiple pens against MSA grids across the turnoff
Your feed, weight, treatment and grid data exist in systems you can pull from
You custom-feed and owe clients a timely, plain-English account of their cattle
The hold-or-ship call currently gets made before the closeout is finished
Walk away if…
You turn off a pen or two a year and reconcile them yourself on the day
Your feed totals or feeder-cattle costs are rough figures nobody fully owns
Weights are paddock estimates, not scale records tied to the pen
You want a tool that makes the hold-or-ship decision for you
Open questions

The worried-buyer questions, answered straight

It can compute a wrong margin — which is exactly why nothing goes to the owner or cattle owner on its say-so. It shows the inputs behind every figure — the mill-log feed total, the ration cost, the grid price, the weights — and frames the exit-timing line as a recommendation, not a decision. The owner or business manager checks the figures against what they know about the pen and stands behind the call. The tool surfaces the numbers; the person makes the hold-or-ship decision.
It works from the figures it can actually pull — feed on a dry-matter basis and ration cost from the mill log, weights from the scale system, pulls and mortalities from the chute book, the grid from the market inputs. If a feed delivery is missing or a weight is a paddock estimate, the closeout is only as good as that input, and the tool cannot tell an incomplete feed total from a real one. Getting those inputs reconciled cleanly per pen is usually the first piece of work — and the piece that pays off across every closeout after.
No. It removes the weekend of reconciling four systems into a spreadsheet, so the business manager or nutritionist spends their time on the judgement — whether the gain looks right for the ration, whether the margin squares with what the cattle cost to buy, whether the pen holds or ships. The closeout stays theirs, attributed to the person who approves it. The capacity it frees goes back into running the yard, not transcription.
Current to the day you close out. The over-the-hooks grid moves, and the carcase value and margin are computed straight off it — point it at last week’s grid and it drafts a confident margin that no longer holds. The same goes for the feed total: it must cover the pen’s full days on feed. The honest test: do you know, today, that the grid price and the mill-log feed total behind this closeout are the current, complete ones for this pen?
A pen’s costs, your feeder-cattle buy-in and a custom-feeding client’s results are commercially sensitive. Any deployment runs against your own systems and data handling, not a shared pool — we scope where the data sits and who can see it as part of the build. The demo here runs entirely on fabricated data; Pen B-14 and Glenroy Pastoral Co. are invented, and the figures are illustrative.
It does the arithmetic and writes the explanation, and it flags where an input is missing, but it does not certify the figures or own the decision. The feeder-cattle cost, whether the grid is current, whether the pen is still gaining, and the hold-or-ship judgement are calls a person confirms against the pen. The tool gets the closeout most of the way; the accountable person closes the gap and stands behind the number that carries their name to a client.
