Parameters (mean ± SD) of the growth curves1for 59 lavender (lav/lav) and 66 wild-type (lav/+) Japanese quail, and effects of the family, sex and plumage colour on the parameters of individual curves
Parameter of the curve Plumage colour (genotype) Percentage of the total variance explained by the model2(R2) Significance of the effect of plumage colour in the Full model
Lavender (lav/lav) Wild-type (lav/+) Full model Reduced model
A 204.4 ± 32.1 215.9 ± 38.3 67 65 *
B 221.4 ± 34.3 233.0 ± 39.6 71 69 *
k 0.0405 ± 0.00604 0.0401 ± 0.00759 43 43 NS

1 with the monomolecular growth model: body weight = A-B-kt, where A is the asymptotic body weight, B is the range of body weight from hatching to asymptotic weight, k is the relative rate of growth, and t is the age in days.

2 The Full model includes the effects of (full-sib) family, sex and plumage colour, and the Reduced model does not include plumage colour.

*: p ≤ 0.05; NS: not significant.
