Figure 1.
Estimated standardized ileal digestible lysine requirements of individual pigs (thin colored lines) and minimal standardized ileal digestible lysine levels to be provided to pigs fed in a conventional group three-phase feeding system (bold red line) without affecting body weight gain according to Hauschild et al. (2010).

Scheme of the automatic precision feeding system operation using individual pig actual daily gain and daily feed intake to predict individual standardized ileal digestible (SID) lysine requirements.
Figure 3.
Figure 3.
Calibrating the precision feeding mathematical model (Cloutier et al., 2015) using four feeds in each feeder. Feeds A1 (130% of lysine requirements) and A2 (70% of lysine requirements) are formulated to meet the pig’s highest lysine requirements, and B1 (130% of lysine requirements) and B2 (70% of lysine requirements) are formulated to meet the pig’s lowest lysine requirements.

Individual feeders allow one pig at time to request feed. Each animal is identified by the ear plastic button tags containing passive transponders, which provide pigs with diets that are tailored daily to individual requirements of each pig.
