concerned but also pure as far as bloodline composition. The process
will, however, take time. It may take at least seven years, often more-too long for practical purposes. Traditional breeders do this. They would
say ―to protect the integrity of our bloodline.‖ Another phrase oftrepeated by traditional breeders is ―I have kept this bloodline for so many
years without any infusion.‖ As a practical breeder, I doubt if it could be
done without severe deterioration or breakdown of the line. But true or
not, right or wrong these phrases always add significance to their bloodlines to the eyes of a potential buyer or newcomers to the game.
But again, for practical breeders, what is important is to purify the
desired traits, not the bloodline. If purifying attributes and characteristics
will do the trick, why bother doing for so many years what you could
achieve in one or two? My personal opinion is that what Dr. Bunan presented was a perfect model for traditional and serious breeders. But, the
Hidalgo model will also work, particularly for practical breeders. In RB
Sugbo, we came up with some sort of a happy compromise between the
two methods, particularly in breeding the blakliz. Our brood fowl are at
least twice inbred. But we don’t go to the extent of going the full route of
five to six generations of inbreeding. The longer you inbred, the higher
the risk of depression and the lower the increase in the degree of being
pure.
After two or three generations of inbreeding we already consider

started by crossing a Bates black cock and
a blue face hen, Then we tried another
cross this time the pullets from the first cross were mated to ponkan, a
sweater brood cock, from Doc. Ayong Lorenzo. Then, because we felt
ponkan was a superior individual, we mated back to him his daughters in
a back-to-father line-breeding. Subsequently we attempted to set the
blakliz as a bloodline by applying the brother-sister mating of the stags
and pullets that were products of the back breeding to ponkan. That was
our first try to set the blakliz as a bloodline. After the stags of the first
attempt were pit tested and the results were deemed unsatisfactory, another crossing was applied. A black bonanza blood was introduced. It
was sort of an upgrading and corrective mating.
Afterward, another series of brother-sister and other inbreeding
techniques were resorted to in order to set the blakliz as a bloodline. In
2007, after three subsequent inbreeding we considered the blakliz a set
