1 The Full model includes the effects of family, sex and plumage colour, and the Reduced model does not include plumage colour.

2 Live body weight was used as a covariable for the analysis of body temperature of 6-month fed quail.

3 Carcass weight was used as a covariable for the analyses of abdominal adipose tissue, breast muscle weight, liver weight, and heart weight.

4 Total weight of the right pectoralis major and pectoralis minor muscles.

*: p ≤ 0.05; ***: p ≤ 0.001; NS: not significant.
