Definition: Market lamb and market goat projects target species-specific weight windows for junior shows. Daily gains are smaller than hogs, so scale precision and consistent logging matter more.
Typical windows (verify locally): lambs often ~110–150 lb; goats often ~60–100+ lb. ADG often ~0.4–0.7 lb/day (lambs) and ~0.3–0.6 lb/day (goats) under good management — genetics and ration change everything.
Worked example: Lamb at 80 lb with 70 days to fair, target 130 lb → required ADG = 50 ÷ 70 ≈ 0.71 lb/day. If actual ADG is 0.5, projected = 80 + 35 = 115 lb — plan adjustments early.
- Measurement error of 2–3 lb is a bigger % of body weight than on a 250 lb hog.
- Record books still need full expense and weight history.
Tools: ADG, fair weight, purchase weight. Guides: ADG, record book checklist.
