@Ebenezer , I agree what you are saying... that the breeds have to measure up to the type and the color patterns in the APA Standard... and many of the colors in some breeds were introduced by crossing out to other breeds to get the color pattern established... and then they had to be bred from there to get back to the TYPE of the bird.... that is where the cattle situation got MURKY.... the type , size , weight, confirmation of the breed got changed and then they got called the breed....
But at least in the chickens, there are types and sizes and weights that are supposed to be met.... get there any way you want.... and then colors.... and many times it took several different breeds to "make a new breed" ... but they didn't call it by the name of an old established breed... like the example of the Araucanas and the newly made and established Americanas.... and they have to be bred by a certain number of breeders and shown and have to become an established producer of off spring that breed true to type....and then will be considered into the APA Standard of perfection.
Yes, there is cross breeding done in chickens... especially to "make a new color pattern" in certain breeds... LIKE Plymouth Rocks..... all the colors that are now available...
But the purpose in my comparison is they have to meet certain standards to be called whatever breed they are called...and here is where things like "reputation" that
@Jeanne - Simme Valley talks about.... a breeder of chickens will not last long if they sell breeding stock and it does not breed true to what they have sold it as.... so as she said, reputation is VERY IMPORTANT as to what you are selling will do what you say and is what you say it is....
It seems to me that there are not very many "standards" as far as what most cattle are to be called true to type... it all goes to the registration papers and that in and of its self can be very misleading if you want to really slide around the 100 % truth of it..... we all have seen it...
Do breeds like Brangus always breed true once the cross is established? The black in many breeds has come from cross breeding with something black.... but what establishes the type of the angus or the type of the herefords, or the type of the simmentals???? Are there breed standards that they should meet? And if so, were the changes that came about... Bigger taller angus back in the 80-90's.... voted on and agreed and the "standards set " then changed to reflect that????
Many of our beef breeds were established to fit a niche where they were bred... and colors were established that also fit the niche there.... herefords were red and white... PERIOD.... so the breeds were not just a certain type or size but were also a certain color when they were established... Like different breeds of poultry, that people bred to create different color patterns with the same type and other basics.... like leg color, egg color, type and stance..... "black herefords" have been created with the color pattern being dominant... but do they meet the criteria for what a "hereford" build and shape is supposed to look like????
It seems to me that creating a breed called sim-angus should mean that the offspring will have a melding of the two breeds to the point that they will have certain defining characteristics of the 2 breeds together and their off spring will breed true to type... not some more "simmi" and some more "angus"..... when bred to each other...
and yes, then the bulls will contribute 50% to whatever cow they are bred to with her the other 50%....so you are again back to a crossbred animal....
That is why we have "backyard chickens" and purebreds... you get a hodge-podge from the backyard birds and the purebreds should all look pretty much as cookie cutter copies of the parents ..... and the ones that are not very good for type and such should be chicken and dumplins.
