1Macrochromosome number.

2Microchromosome number only is presented in the rows of the table (see Additional file 3: Table S3)

WA = asymptotic (estimated mature) body weight, i.eWo*exp (L/K), g.

Ti = age at point of inflection, where Ti = (1/K)log(L/K), d.

K = rate of exponential decay, g/d.

L = growth rate per day at day zero, g/d.

W0 = hatching weight, (y –intercept), g.

The position (cM) of QTL for weight at a specific age (normal font), growth between successive ages (italic font) and Gompertz curve parameter estimates (normal font) are itemised. Genome significant (P < 0.05) QTL are in bold font; suggestive (chromosome significant) QTL are in regular font.
