DOMINANT BLACK D 109 is a classic, very popular program. It is used as a final hybrid for self-sufficient farms in the Czech Republic and other European countries. At the same time, it is also used for exporting grandparent and parent breeding pairs to Africa, Asia and America, where it is also used for intensive production of table eggs. Capons are fattened to produce traditional, highly delicious poultry meat.
The asset is the high productivity, namely laying over 310 eggs, verified in cage-intensive farming conditions at a testing station. Light brown eggshell colour is characteristic. The black feathers of adult laying hens are attractive with a distinctive metallic blue-green lustre, complemented by neck and chest feathers having contrasting brown marking. The cockerel is barred with brown feathers on the neck, chest and wings.
This program is the result of cross breeding the Rhode Island Red (RIR) paternal population and the Barred Plymouth Rock (BPR) maternal population. Colour sexing is applied when hatching one-day-old chickens using the "B/b" allele of the Barred gene, where one-day-old cockerel acquires the dominant allele of this gene "B" from its mother and is barred with a white dot on its head and one-day-old hen acquires the recessive "b" allele from her father, which does not cause barred marking, and consequently the hen is dark without white marking on her head.
