Dry brewery residue in broiler chickens feed
The residual from the food industry has the potential to replace the traditional ingredients used in animal feed, and the dry brewery residue (DBR) may be an alternative for this purpose. This study aimed to evaluate the use of DBR in the diets of broiler from 22 to 42 days of age. Five hundred and...

This study aimed to evaluate the use of DBR in the diets of broiler from 22 to 42 days of age. Five hundred and forty-six male broilers were used, with an initial average weight of 865 ± 8 g.

The residual from the food industry has the potential to replace the traditional ingredients used in animal feed, and the dry brewery residue (DBR) may be an alternative for this purpose.
