dominant black d 189-凯发k8娱乐旗舰厅
dominant black d 189 was created to order by business partners from mexico with a requirement for fully black cockerels. it is used commercially as a final hybrid or parent breeding pairs for self-sufficient farms in the czech republic and other european countries and also overseas. capons are used to produce traditional, highly delicious poultry meat. high productivity, namely laying over 290 to 300 eggs is appreciated. light brown eggshell color is characteristic. the all-black black basic plumage is attractive for both cockerels and hens.
this program is the result of cross breeding fast feathering black plymouth rock paternal population of "kk" genotype and the slow feathering also fully black plymouth rock maternal population of "k-" genotype. when hatching one-day-old chickens, sexing according to feathering speed is applied using the "k/k" allele of the feathering gene, where one-day-old cockerel acquires the dominant allele of this "k" gene from the mother and is slow feathering and one-day-old hen acquires the recessive "k" allele from the father, which causes faster growth of flight feathers in one-day-old chickens.
