New residual feed intake criterion for longitudinal data.

Genetics, selection, evolution : GSE - 25 Jun 2021

David Ingrid, Huynh Tran Van-Hung, Gilbert Hélène

Abstract excerpt

BACKGROUND: Residual feed intake (RFI) is one measure of feed efficiency, which is usually obtained by multiple regression of feed intake (FI) on measures of production, body weight gain and tissue composition. If phenotypic regression is used, the resulting RFI is generally not genetically independent of production traits, whereas if RFI is computed using genetic regression coefficients, RFI and production...
