  1. Heritability estimates (h2) of traits and genetic correlation (rg) estimates between traits estimated on full dataset versus traits estimated on reduced datasets are given. Pairwise Pearson correlation plots for each trait over different observation frequencies are given in Additional file 5: Fig. S3. Genetic parameters were estimated via pedigree evaluation, using only pedigree relationships. ADG: average daily gain; AFI: average feed intake; FCR: feed conversion ratio; A, B and k: Gompertz growth curve parameters; lnvarweight: natural logarithm of variance of observed versus predicted weights; lnMSEweight: natural logarithm of mean squared error of weight in function of age; lnvarweight_standardized: natural logarithm of variance of standardized weights; skewweight: skewness of observed versus predicted weight distribution; lag1weight: lag1 autocorrelation of observed versus predicted weight distribution; straightness: straightness index of weight in function of age after trajectory analysis; mean speed: mean speed of weight in function of age after trajectory analysis; lnMSEFI: natural logarithm of mean squared error of feed intake in function of age; lnMSEdur: natural logarithm of mean squared error of visit duration in function of age; lnMSEn_visit: natural logarithm of mean squared error of number of daily visits in function of age; QRFI: number of days with feed intake below 5% of quantile after quantile regression; QRdur: number of days with visit duration below 5% of quantile after quantile regression
