- •
We quantified performance and body composition of broiler on intakes of valine.
- •
We used the dilution technique, with valine as the first limiting amino acid.
- •
Three trials were conducted separately in the initial, grower and finisher phase.
- •
Valine for performance and body composition were estimated from broken-line models.
- •
Results indicate recommendation of digestible valine is 226; 637; 1231 mg/bird/day.
