Extract

The dam's milk production, mothering ability and the lamb's own genetic potential are important for preweaning growth. If there are strong maternal effects, which have not been separately accounted for, they can bias the estimates of heritability.

The objective of this study was to estimate genetic parameters for 12 week weights in Welsh Mountain lambs, and to assess the relative importance of the maternal genetic effect in this trait.
