Game fowl bloodline is referring to as the type of game fowl or the kind of breed of game fowl that a breeder is having in his or her position. Game fowl bloodlines differ from characteristics like the plumage, body size, height and what is important is fighting style. Some of the game fowl or fighting cocks bloodline that are famous are the hatch, kelso, lemon, grey, sweeter, English Dom, round head, black bonanza, mel simm, claret, butcher and asil. These game foul bloodlines need to be preserved for the future breeding.
One of the breeding methods that are used by some of the game fowl or fighting cocks breeders is the type of breeding that is called in-breeding. It could be done by mating back for example pullets to the brood cock or a stag to the hen. For example you breed the lemon hen to the roundhead roaster then you produced an offspring composed of fifty percent lemon and fifty percent roundhead. If you want to preserve your lemon bloodline then you are going to breed back the fifty percent lemon and fifty percent stag to the original lemon hen and then you can produced an offspring composed of seventy five percent lemon and twenty five percent roundhead. If you want to have a breed of almost one hundred percent lemon then you are going to breed back the seventy five percent lemon stag to his mother hen (the original lemon hen) and you can get almost a one hundred percent lemon offspring. But take note that you can only use that in-breeding offspring in cross-breeding not to be used as a battle cross. That is how some game fowl breeders preserve their bloodline.
Another way of in-breeding that is used to preserve the bloodline of a game fowl is to breed using the same hen with different roaster then breeds again their offspring. For example in my case I want to preserve my black bonanza bloodline, what I did is I mate first my black bonanza hen to a hatch roaster then I produced an offspring composed of fifty percent black bonanza and fifty percent hatch. Next breeding season I breed again my black bonanza hen to a sweater roaster then I have a fifty percent black bonanza and fifty percent sweater offspring. Finally to preserve my black bonanza bloodline I breed the fifty percent black bonanza and fifty percent sweater hen to a fifty percent hatch and fifty percent black bonanza roaster. In that way I have preserve my game fowl bloodline, the black bonanza.
Game fowl breeders need to do in-breeding to preserve their game fowl bloodline. The product of in-breeding usually is for breeding material purpose and not to be used as battle cock. The output of in-breeding is usually use in cross-breeding in order to produce a battle cock.
