[Abstract].h[electronic resource]  aIn: Annual Meeting of the European Federation of Animal Science (EAAP), 72., 30 August - 3 September 2021, Davos, Switzerland. Book of abstracts. Wageningen, NL: WAP, 2021. p.115. doi: https://doi.org/10.3920/978-90-8686-918-3c8686  aConference website: www.eaap2021.org  aResidual feed intake (RFI) is the difference between an animal?s actual feed intake (FI) and its expected feed intake based on its size and growth or level of production. There is a lack of studies investigating the incidence of wool growth in the RFI estimation. This study aimed to compare different models for the estimation of RFI in Merino lambs, based on data of 577 animals, born in 2018 and 2019, sired by 16 rams.  aMerino sheep  aResidual feed intake (RFI)1 aCIAPPESONI, G.1 aVELAZCO, J.I.1 aNAVAJAS, E.1 aFERREIRA, G.1 aRAMOS, Z.1 aROVIRA, F.1 aDE BARBIERI, I.
