Inclusion of marigold flour in the diets
did not affect final body weight, feed consumption, or egg
production of the chickens compared to the control group.
However, supplementing high level of marigold flour into the
diet significantly reduced egg weight compared to the control
and the laying hens fed the diet containing the lower level of
marigold flour. Inclusion of marigold flour at the high level
of marigold significantly decreased egg weight for every week
starting from week one compared to the control (not shown
here).
