Importance of F/G• For each 0.10 lb improvement in F/G,

profit increases by $3.0 per marketed pig• A 10% improvement in F/G corresponds to

an improvement of 0.30 lb ($9.0/pig)

Tip 1: Tip 1: Start with what you can control Start with what you can control • Reduce feed wastage

Check all feeders, delivery systems, feed binsAdjust feeders routinelyImprove pellet quality

Poor feeder adjustment

• Calculate economic return• (New Diet $ - Old Diet $) x 100 = % improvement Old Diet $ in F/G needed

to pay for itself• Consider other benefits – gain– carcass quality– death loss
