Some strains have many. Even though you are careful in your selection and breeding practices, you may still experience a number of characteristic that will need to be selectively bred out and eliminated. When this happens, do not despair, as there are other techniques which you can use to overcome this problem. In order to correct or modify these undesirable weaknesses or characteristics, there are times when you will need to add new blood. By adding characteristics of another bloodline, some families can actually be improved. HOW TO INFUSE NEW BLOOD: When introducing new blood, it is a good idea not to infuse it haphazardly. It is beneficial to determine how well the new blood will nick with the blood of your birds before going full force. For instance, lets say you have purchased a cock, which you believe will improve your fowl. He should first be mated to three or four selected hens as an experiment or trial mating. The quality of the offspring from this mating should be carefully evaluated. If the results are good, you can most likely integrate the blood of that cock into the rest of the family. This will not only give you an opportunity to test out the fitness of the new blood, but by using the offspring of the trial mating it will cut down the percentage of new blood introduced on the family as a whole, thereby lessening its disturbing influence. THE 1/16th INFUSION METHOD: This method is the introduction of a strain into an already established strain, for the purpose of improving its characteristics in small but significant increments. It is not used to completely change the strain. It is also used for refreshing the bloodline. The idea is to breed a special individual into your family that will compliment or improve your family. For example, in a family, such as a Hatch, the idea is to introduce blood, such as Aseel, and then breed back to the Hatch bloodline until you are at 15/16ths of the Hatch blood, and 1/16th of the Aseel blood. Once you reach this point, line-breed to the Hatch side. What you are left with is a family that is a little better in some areas of its makeup. AVOID THE GUESSWORK: It is very difficult to raise standard-bred, high-quality American Games if new blood is added to the family each year. You may buy a purebred broodcock to mate with your purebred hens, and later find that the two strains failed to nick. In short, the introduction of new blood is a matter of guesswork, not good breeding practice. If it is your desire to introduce new blood, the rule should be to do so, not just because it is new blood, but because it is far superior to your own in many of their attributes. TAKE YOUR TIME: A better way to introduce new blood is to take three years to do it, and experiment with the individuals produced before going into it full force. Purchase a few hens of the desired strain and mate them to your best cocks, or secure a couple of good cocks and mate them to your best hens. Then study the progeny for a couple of years, and if they are satisfactory, mate the new blood to the rest of the family. KNOW THE RISKS: Although many breeders tend to infuse outside blood, you have to be very careful you dont ruin the originality of your family. If it becomes necessary to infuse blood into your family from an outside source, be very careful about the blood that you add. I personally would not infuse new blood from an outside source into my family. However, if there came a time that I found it necessary to do so, I would infuse the new blood into a small group of my birds first, and make a separate family out of them. If in time the infusion look to be beneficial and did not bring in new weaknesses, I would then begin to integrate it into the rest of the family. I would do it slowly though. In fact, I would do it one line at a time, starting with the worst line. INFUSING BLOOD FROM ANOTHER LINE OF THE SAME FAMILY: this is by far the best method of infusion. There are fewer risks and many more benefits. If I should experience a number of characteristic that I will need to eliminate or breed out, I will breed a cock or hen from one of my other lines that is especially strong in those areas into the line in question, then breed it back out by line-breeding back to the original line. If it is Line A that is having all the problems, I will infuse blood from Line B, and then breed Line B back out, leaving the good qualities of Line A and replacing the undesirable qualities of Line A with the attributes of Line B. ITS IMPORTANT NOT TO INTRODUCE THE UNDESIRABLE: With the introduction of new blood into an established family, it is very important not to introduce undesirable inherited characteristics or diseases. The idea is to strengthen the family, not weaken it. In any well-bred family, the danger of deterioration through the introduction of new blood is much more real than any danger of deterioration through lack of new blood. I do believe that a blending of bloodlines tends to bring out latent or dormant ancestral characters. Therefore, before making extensive use of a bird of unknown breeding, try the new blood in special matings for a number of years in order to find out how it will “nick. There are breeders who are always trying to produce something which does not already exist. Some are interested in producing a new breed and others are interested in improving an existing breed. Even after a good deal of experience, they are still prepared to take chances on a new bird that has caught their attention, and will quickly infuse it into their general matings, usually by crossbreeding. Often with faulty results, requiring years of careful breeding to eliminate, and which will crop-out all through the progeny. The experienced breeder never relies on a new bird until he has fully tested it. He will maintain the family in its original form until breeding tests proves the new infusion has been successful.

It has always been my objective to inspire more breeders, and to provide breeders the tools they need to create the fowl of their dreams, and achieve their goals. It’s a long journey, but a worthwhile one. Sincerely, Kenny Troiano
