rate. Studies have shown that weighing broilers
between seven and 21 days of age efficiently reduce
mortality due to ascitis, sudden death, leg problems,
etc., allowing adjusting bird density during rearing
to improve performance and profitability, in addition
to bird welfare. Inadequate weight density per area
causes leg problems, scratches, bruises, and mortality
(Cobb-Vantress, 2009).
