Selection for feed efficiency in Duroc pigs with the addition of daily feed intake data in a 2-stage selection procedure
The objective of this study was to evaluate the effect of including feed intake records of boars
on the genetic gain for feed efficiency. Data were obtained from a Duroc nucleus herd within
a Chinese company's breeding system. The data obtained included ADG, feed conversion
ratio (FG), ADFI, days to 115 kg, backfat depth, and loin muscle area. The ADG, FG, and
ADFI data were obtained from 570 Duroc boars housed in pens with electronic feeders
(FIRE, Feed Intake Recording Equipment, Osborne Industries, Osborne, KS). There were …
