Reproduction
Lambing events, age-at-first-lambing, lambing interval, lambs-weaned-per-ewe-per-year. The data here drives the fertility component of every $ index — including the multiplier that makes accelerated lambing systems pay for themselves.

System scenarios how each pattern performs under your flock
Lambings/ewe/yr ("LPEY") under each system, given your flock's MTNR1A carrier frequency and current nutrition score.
Age-at-first-lambing tradeoff
Earlier joining brings forward lamb output by up to a year — but conception rate drops if ewe-lambs aren't grown out properly.
Record a lambing event
Each event ties to a ewe ID. Days-since-prev-lambing is computed automatically by the database trigger.
