What is the breeding weight of gilts?

In a trial, gilts were fed one of three different treatments: corn-soybean meal diet formulated to 0.95% lysine, corn-soybean meal diet with 5% added fat formulated to 0.60% lysine (fed from 150 to 250 lb.), or a high-protein diet restricted to 4 lb./day intake.

Recommended management at puberty
- Record pubertal gilts’ ID using existing tag/spray mark.
