Commercial brown-egg layers have the genetic potential to produce 26.5 kg egg mass per hen housed (405 eggs with 65.5 g average weight) in a prolonged laying period of 16 months, with a feed conversion ratio of 2.1 kg feed per kg egg mass (Lohmann Tierzucht, 2011). Rapid growing broilers reach market weight of 2.1 kg live weight in 5 weeks, with a feed conversion of 1.6 kg feed per kg live weig...
