Report on nutrient needs organic chickens
A new report has been published by the Animal Sciences Group from Wageningen
UR in the Netherlands. In this literature review, 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 on the one
hand the need of nutrients for maintenance, and on the other hand the need of
nutrients for production. It is suggested that energy requirement of organic
housed poultry is higher compared to conventional housed poultry as a result of
three different factors.
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.
