Let's not get all tied up in knots over a name. Who cares whether they are called appendix or Shorthorn Plus ( or Minus... depending on your point of view). The name should take second place to documented records of what the ancestory is. I doubt if we would all even agree on what is a purebred.... in Shorthorns or any other breed.I really doubt if there is really such a thing as a "purebred" in any breed ( if one uses the strictest definition) For example, is a Shorthorn with Irish Shorthorn genetics in its makeup a purebred? Most of you would most likely say yes to that question. I would have to disagree with you as I have never considered the Irish cattle as being purebred breeding stock, simply because there was no records kept by most of the Irish breeders for many years, even decades.
I believe we were the second breeders in North America to import cattle from Ireland. We brought in a bull and two females shortly after Beef Genetics Research in Kansas imported the first ones.We purchased cattle in Ireland on three occasions, and were in the process of negotiating the purchase of a plane load of Irish cattle, when Brucellosis broke out in Ireland. I had many visits with the Irish breeders and it was almost impossible to get the same pedigree from a breeder twice. I will always remember visiting with a leading Irish breeder at a US show, and he gave me a completely different pedigree on one heifer, three different times in one conversation. To my knowledge, there were three females imported into North America that had the exact same name, but had completely different pedigrees. I also remember a discussion with a group of breeders from Ireland, in which we were discussing the Deerpark herd owned by the Quane Brothers. I asked where the Quanes had found Deerpark Improver, as they had kept their herd closed for decades and Improver had a completely different pedigree on his sire's side,( and there was only two generations at that!). They told me that Deerpark Improver's sire, Clare Man, was a red bull calf that had been purchased at a local auction market. My theory is that Clare Man was a red horned bull of mixed breeding that most likely consisted of Galloway along with Shorthorn and possibly other breeding as well. The Galloway breed wrestled with TH, 20 to 30 years ago. Doesn't it seem strange that two breeds would have the identical genetic defect appear? Yes, it is possible, but it is also very highly unlikely.
Did this knowledge that the Irish cattle were less than pure, stop me from purchasing them or using them in my herd? Absolutely NOT! Did I trash Deerpark Improver or his offspring, or not use them in my herd? Absolutely NOT! At the time I did feel that the Irish cattle should have remained in the Appenidx book but once the breed associations allowed them into the closed book, I was perfectly fine with this decision. Anyone who has been a pedigree student for any length of time, knows that there has been other genetics allowed into the breed ( and ALL other breeds I might add), and some of it came in through the back door.
I saw in these cattle, some traits that the Shorthorn breed desperately needed. The Irish cattle were far from perfect but they had some attributes that could correct a lot of issues that were problems. The Irish cattle were a very important tool in the Shorthorn breed in that they helped clean up udders, they helped eliminate some waste especially in the lower their of the animals, they improved the rump structure on Shorthorns as they had excellent thickness from hooks to pins, and they were an important tool in increasing the muscle in the Shorthorn breed. We were also running a feedlot at the time were were importing cattle from Ireland and we got carcass data on many Irish cross steers. Most of the cattle that had Irish blood consistently had at least 2 square inches more ribeye than those cattle from traditional Shorthorn sires at the time. The Irish cattle were a tool.. nothing more.
My point is, let's not get hung up on names. Let's spend more time breeding good breeding cattle. Let's call a good animal Good, regardless of whether it is a so called purebred or an Appendix. I know we could argue about what good breeding cattle look like, but that is a decision for another time.I do think that the definition of a good cattle beast will vary with the enviroment in which it is going to live. In other words, an ideal animal in the midwest states ( Illinois, Indiana et al) will probably lok a lot different than an ideal animal in parts of Wyoming, Montana and Utah.
I am seeing a trend presently in which breeders are going back and using sires from past decades. There have been several threads on this site about some of these sires. Personally, I have sold more semen from sires from the 60s and 70s in the past 3 months than I have on these same sires in the past 20 years. I do believe that these sires do offer some things that could be beneficial to today's breeding programs. I am using some of these sires myself. I would caution that we not get too carried away in using these bloodlines and also say that they should be used on select females that compliment these sires. They are a tool to use for selective trait improvement, but they will not solve all wrongs. If that was the case, we would have been using them all again, long before now.
