The aim of the study was to develop a method for conservation of chicken biodiversity through their efficient
use. The study involved Greenleg Partridge (Z-11) and Rhode Island Red (R-11) hens. Within each breed the control
group (K) consisted of 60 hens, which were kept on litter without outdoor access and received a diet containing
65.3% domestically produced feed components. The experimental group (D) was comprised of 60 layers, which
were kept on litter with free-range access (11 m2
per bird) and fed a diet in which the proportion of domestically
produced feed components was increased to 77.1%. The eggs from hens of both breeds, which received the diet with
an increased proportion of domestically produced feed components, were of good quality. This shows that the freerange
production system of native breed chickens is appropriate and that domestically produced feed components
can be put to appropriate use in extensive chicken farming. These measures are consistent with the EU policy for
sustainable agriculture and biodiversity conservation while enabling breeders to obtain additional financial support
