Your data

Upload your herd and bull files, then set the size of the comparison list.

Last year's bulls

Used to compare this year's plan with last year's matings, on D. Herd Progress. Where a calf in your herd file shows it, her dam is filled in for you.

Upload a file

An Excel or CSV file with a column for the cow (name, tag or number) and a column for the bull (name or number).

Enter them by hand

Click a cow to set her bull. Bulls you have already entered are offered first.


Build your breeding index

Answer nine questions, then adjust the points. Save when they total 100.

Ten areas · 100 points

Nine questions

Nothing applies until you save.

Sets the money figures. No points.

+6, +4, +2. Taken from what you did not pick.

No points. Opens robot checks.

Adds a guardrail. No index points.

Yes gives every cow a dairy bull, straight away. No - then choose the beef share just below the nine questions. Both take effect as you choose.

Recorded for costs. No points.

Which cows get a dairy bull?

Takes effect the moment you choose it - there is nothing else to press. Your cows are ranked on their own index score and the share you name is taken off the bottom: those cows are marked BEEF on A. Cow Rankings and get no dairy recommendation. It never puts more than half the herd on beef.

How your herd is doing

What your cows actually do, rather than their genetics. It tells you where breeding will not help. Fill in what you know; it is remembered until you change it.

Milk
Health, fertility and youngstock

How the milk figure was read
Old question set — FOR REVIEW, scores nothing
For review. Replaced by the nine questions above. These answers are recorded but score nothing.
Block calving makes fertility the single biggest priority.
This works both ways: say so if you want MORE frame, not less.
Under review, and it changes nothing. The robot suitability checks read question 5 of the nine above, not this. The three figures below are recorded for the advisory conversation and are not used in any calculation.

This sets how much of your hundred points goes to Lameness. You are asked separately what lameness costs you -- that answer sets a guardrail instead.

This sets the Calf survival priority. It covers tagging to 10 months, excluding stillbirths and deaths in the first day.

Order matters. The first one you pick counts for most. These are the same ten the engine scores, so whatever you pick here arrives ranked in the same words on 3. Confirm Priorities . The three in the second group still add weight to Health, but SireWise scores no trait for them, so they cannot be ranked.

Guardrails

A guardrail refuses any bull whose daughter would fall below a line you set. These are suggestions -- nothing is applied until you confirm it.

Tick anything you are already managing a problem with - often something your vet has flagged. Ticking it does not chase improvement; it stops the engine offering a bull whose daughter would come out below that cow's own current level.

Confirm your top areas for improvement

Prefilled with your answers from Your Farm. Confirm or change them in light of where your herd actually sits, shown below.


Your AI companies

Choose the companies you can buy from and set their minimum order rules.


Your bull preferences

Set the exclusions and allocation limits that apply to every recommendation.

Bulls you cannot get

Shared ancestry

A management preference, not an inbreeding limit. Counts recorded sires and grandsires only.

2nd and 3rd choice bulls

On: each cow's backups on B. Selected Mating are bulls you are buying (C. Bull Usage). Off: her next best of every bull that passed your limits above. Neither changes the plan or the order.


Selected mating

One row per cow: the bull she has been given, and who sells him.

↓ Excel (with your settings) ↓ CSV (settings on a different tab)

Click any cow to choose her bull yourself - her bull now and her 2nd and 3rd choice are offered first, or pick any bull from your file.


Bull usage

How many straws from each company, and which bulls the plan uses.

How well proved these bulls are
Shared ancestry across the bulls used

Herd progress

Two shape comparisons on the same ten areas: what your index asks for against the standard, and where this mating plan moves the herd.

Expected results

In each trait's own units.

This year's plan against last year's bulls

The calf expected from last year's bull and from this year's planned bull, on the same cows.

Cow by cow


Each cow's choices in order

One row per cow, ranked the same way as Cow Rankings. The columns are her 1st, 2nd, 3rd choice and so on, from the same ranking as the matrix above.


Herd summary


Risky pairs

Two kinds of risk, checked for every cow against every bull in your file: related parents, and parents who carry the same recessive.

Recessives & haplotypes

Pairings where the cow and the bull carry the same recessive condition. Each parent passes on one of its two copies, so a calf could inherit two -- for the HH haplotypes that is a lost pregnancy, for the others a sick or dead calf. Checked for 13 conditions, from the codes in each bull's name and the carrier statuses in your herd file.

What your files can support

Every pairing not allowed


Illustrative economic weighting

Read these as a set. Each row holds every other trait still, so the negative milk row means more litres at unchanged fat and protein — water.
What these figures are, and are not

Expected calf PTAs, not a calf's performance. A reconstruction of a published index on a monetary scale, not a farm-profit forecast and not your own index. Correlated traits cannot be given separate causal prices by a good fit alone. Check your contract, costs and replacement numbers before acting. Model details: ROI_CALCULATOR_EVIDENCE.md .

What this plan is worth

Per trait, on your contract. Not added up.

How each figure is worked out
Every assumption, and where it came from

Every number behind the ranking

One row per cow against her top bull. Her own figure, the bull's, and the midpoint the engine scored - then the weighting each area carries and what it contributed. The columns multiply and add out to the total on the right.

File formats

Leave these alone unless an upload was read wrongly. SireWise detects most files on its own.

Where your files come from
AHDB reports use Identity as the stable animal key, Line as a display number, and Herd as the herd identifier. Naming the source lets SireWise map those without guessing.
Changing these affects the NEXT upload. Re-upload from 1. Your Data to apply them.

Supporting views not in the live workflow

Cow Summary, Top N per Cow, Bull Ranking Chart, Score Breakdown and Risky Pairs are retained in the codebase. They will be reintroduced only after their role is agreed and browser-tested. Saved runs are back, behind the Saved runs button beside Save Run.
