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.
