Overview:
This table contains the fundamental metrics that every broiler farmer’s profits are standing on.
In summary, the table gives you a day-by-day account of…
- how heavy you should expect a Cobb 500 broiler to weigh from day 1 of hatch
- until the processing date
- and how much feed they require daily to reach the target weight
Why this is important
From these figures, you can build very accurate (yet, complex) broiler farm production models and investment proposals.
