DOMINANT PARTRIDGE D 300 is a very attractive coloured program reminiscent of the Partridge or Golden Partridge breeds, with the difference that our program enables to sex one-day-old chickens according to the flight feathers growth rate and compared to the original breed reaches significantly higher laying rate, namely over 280 eggs. Another program characteristic is the variability in eggshell colour, from white to light cream. It is very popular as a final hybrid for self-sufficient farms in Europe and also in Asia and America. The starting genetic material for this program is synthetic lineages created from the Brown Leghorn, Rhode Island and classic White Leghorn lineages.
This program is the result of cross breeding two synthetic Brown Leghorn populations. The parental population is fast feathering with allele of the recessive gene "k" for feathering rate "K/k" and the maternal population is slow feathering with the dominant allele "K". When hatching one-day-old chickens, feather sexing using the "K/k" allele is applied, 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 and is fast feathering, which is evident on one- day-old chickens’ flight feathers.
