Report: nutrient needs of organic chickens
In a report published by the Animal Sciences Group
from Wageningen UR in the Netherlands, the physiological basis for possible
differences in energy and protein requirements of organic versus conventional
poultry is investigated.
The energy and protein requirements of poultry are determined by the need
of nutrients for maintenance, as well as the need of nutrients for
It is suggested that energy requirement of organic housed poultry is higher
compared to conventional housed poultry as a result of three different
The authors of the report hypothesize that energy requirements of organic
housed poultry are increased as a result of higher energy need for maintenance.
Protein requirements, however, seem to be similar for organic and conventional
housed poultry. Therefore, energy to protein ratio of organic poultry diets
might be increased.
