Abstract excerpt
Days to reach 113.4 kg, adjusted backfat depth and adjusted loin muscle area to 113.4 kg were evaluated on pure-bred Landrace (n = 15 660) and Yorkshire (n = 14 808) boars and gilts. Daily lactation feed intake (LFI) was recorded within parity records from pure-bred Yorkshire (n = 1587) and Landrace (n = 2197) females during day 1-22 of lactation, and LFI curves were predicted using a mixed model. Evaluation of...
