New residual feed intake criterion for longitudinal data

HIGHLIGHTS

• who: Ingrid David from the reviewed by Clutter [47]Longitudinal estimates for these traits are more rarely reported in pigs. For FI and RFI over , consecutive weeks of growth in three pig breeds, Shirali et_al [36] reported estimates of heritability ranging fromtoand fromto, .20, respectively. As in our study, heritability estimates tended to increase with time for FI but their estimates followed a, shaped curve for RFI and were lower than in our study. Using random regression approaches with different splines and Legendre polynomials, Cai et_al [48] reported estimates of heritability for longitudinal FI, BW, BF between . . .
