Carcase assessment addresses conformation and fat.

Fat cover is scored on a 1-5 scale with 1 being the leanest and 5 being the fattest. Conformation is assessed from S to P, with S being the most shapely and P being of poor shape. Combining scores for conformation and fat determines the markets which lambs suit best, eg R3L.

Aim for most animals to fall within the green shaded area, where there is greatest demand and highest prices.
