Bid advisor

Calculate the maximum economically justifiable bid for any ram you're considering — the present value of the lift he'd deliver to your flock over his service life, less costs, less your margin of safety. Built on the same Monte Carlo as ram-impact, anchored to your context.

Bid Advisor — Ram Valuation

—

Pick a ram to evaluate

Search by tag, paste an animal ID, or pull the first ram from your comparison cart.

Service-life assumptions

Default values reflect typical Australian Merino / Maternal practice. Override anything that doesn't match your operation.

Ewes joined / cycle

How many of your ewes you'd put to him each joining.

Lambing system

Drives lambings/ewe/year. STAR ≈ 1.67 vs annual = 1.0.

Lambs weaned / ewe / lambing

Per-lambing NLW. Mult'd by lambings/yr from system.

Age at first lambing

Earlier joining = earlier first lamb crop = NPV uplift.

MTNR1A (out-of-season cycling)

Lifts conception in out-of-season joinings. Auto-set if SNP present.

Service life (years)

How many years you'd use him as a sire.

Discount rate (%)

Your cost of capital. Higher rate → lower bid.

Annual mortality risk (%)

Probability he dies / becomes infertile each year.

Transport cost ($)

Auto-estimated from distance × $0.35/km on load.

Annual maintenance ($)

Vet, supplement, replacement insurance per year.

Margin of safety (%)

Buffer below P50 — your firm bid ceiling.

Year-by-year cash flow

Median (P50) progeny lift × ewes × lambs/ewe, mortality-adjusted, discounted to present.
