Is FCR sensitive to climate?

Yes — every 1°C outside ideal adds ~1-2 points to FCR. Consistent climate control is the biggest single FCR lever after genetics.

What about phase feeding?

Modern broiler diets are 3-5 phases; total-cycle FCR is what matters for feed procurement. Use phase % for silo sizing.

Feed

Feed consumption — total kg per cycle.

Compute total feed intake for a broiler cycle from bird count, target live weight and FCR, or for a layer flock over a defined production period.
