From Cobb 500 Broiler Performance Objectives (April 2018) #

The table below is an excerpt of the (April 2018 version) Cobb 500 Broiler Performance & Nutrition Supplement.

It shows the critical relationship between:

  • age of bird in days or weeks (from hatched)
  • body weight in grams
  • feed consumed in grams

(It is possible with such figures to calculate feed conversion ratio.)
