Yes. The Suffolk exists to grow lambs fast, and a breed whose value is growth rate is a breed whose management should run on growth records. In a Suffolk flock the key questions are all numerical: which ram's lambs gain best on your pasture, which ewes consistently wean heavy twins, which lambs are ready to draft this week and which need another fortnight. None of those can be answered from the look of a pen of black-faced lambs, however experienced the eye. A health and weight log is the difference between raising Suffolk sheep and actually running a Suffolk program.
The Three Weighings That Drive Everything
Build the log on three lamb weighings: birth weight, a mid-season weight at roughly eight weeks, and weaning weight. Birth weight against birth type flags lambs that started behind; the eight-week weight is mostly a report card on the ewe, since a lamb that age is growing on milk; weaning weight combines both stories and starts the lamb's own account. Record the sire and dam with every lamb entry — a growth figure without parentage cannot improve the next generation, which is the entire point in a terminal sire breed. Note creep feeding or its absence beside the weights, because a lamb's growth line means one thing on creep and another on grass alone.
Health Entries That Protect the Growth Line
Between weighings, log the events that interrupt growth: parasite checks and treatments with dates, hoof trims and any limping, scours or setbacks in young lambs, and condition scores for ewes at flushing and lambing. In a fast-growing breed, a two-week stall is a significant share of a lamb's season, and the log is how you learn whether stalls cluster around one pasture, one period after rain, or one sire group — three different problems with three different fixes. Ewe entries matter as much as lamb entries: a Suffolk ewe's milking shows in her lambs' eight-week weights, and her own condition score at lambing explains most of the variation before it happens.

Ewe Longevity Is in the Log Too
Suffolk discussions center on lambs, but keep the ewes' long game in view: teeth condition at each pre-breeding check, udder soundness after weaning, and how each ewe's condition held through lactation. A ewe whose lambs grow brilliantly for two seasons and then fade is often a ewe whose teeth or udder are going, and the log catches the reason before the cull pen has to guess. Longevity in the ewe flock is worth as much as growth in the lamb crop.
When sale and drafting time comes, the log replaces the walk-through guess with a list: these lambs have hit weight, these are a week away, this one's growth flattened after a treatment and needs a second look before it goes. At breeding time it identifies the ewes and ram lines earning their place. Share the growth and treatment history with your vet when performance disappoints — the dates turn a vague 'the lambs did poorly' into a diagnosable pattern. And when a proven ewe or ram lamb is sold, its documented record is real added value to the buyer. KinsLe's Pet Passport keeps each Suffolk's weights, parentage, feeding notes, and health entries in one portable record, so every drafting and breeding decision rests on the flock's actual numbers.
