Standard errors of genetic correlations are given in Additional file 3: Table S1. Genetic parameters were estimated via single-step genomic evaluation, integrating both pedigree and genomic relationships. ADG: average daily gain; AFI: average feed intake; FCR: feed conversion ratio; A, B and k: Gompertz growth curve parameters; Fat: fat depth; Muscle: muscle depth; lnvar_wg: natural logarithm of variance of observed versus predicted weights; lnMSE_wg: natural logarithm of mean squared error of weight in function of age; lnvar_st: natural logarithm of variance of standardized weights; skew_wg: skewness of observed versus predicted weight distribution; lag1_wg: lag1 autocorrelation of observed versus predicted weight distribution; straight: straightness index of weight in function of age after trajectory analysis; speed: mean speed of weight in function of age after trajectory analysis; lnMSE_FI: natural logarithm of mean squared error of feed intake in function of age; lnMSE_d: natural logarithm of mean squared error of visit duration in function of age; lnMSE_n: natural logarithm of mean squared error of number of daily visits in function of age; QR_FI: number of days with feed intake below 5% of quantile after quantile regression; QR_dur: number of days with visit duration below 5% of quantile after quantile regression
