In the Angus breed Touchstone Angus have also a linebred herd. I find it interesting that both Shoshone and Touchstone are in Wyoming. Perhaps there are some equal to it, but there is no country more demanding on cattle to perform than Wyoming. My 2nd Great Grandfather was an early...

I've bred the identical pattern before with dogs for a buyer in Georgia to whom I shipped a bred matron. This was my recommendation to him. He has been very pleased with the result. 75% on the sire (Eros 1702) back to a bro-sis bred dam (1706). It is a tight breeding, but if the quality is...

Pedigree link is not working for me HS. In the Angus breed though, I like the Wye Angus cattle, they are bred right. I have a good friend with a moderate sized registered Angus program. I was telling her i felt they were the best bred Angus out there. Coincedentally, she perked up and told me...

It could be discouraging, but the successes observed along the way are worth fighting the battle in my estimation. There is nothing like knowing you have a relatively clean and predictable genetic base from which to draw. The kind which prove themselves in open competition or evaluation to be...

Your link had this quote Hereford Sire: It will be found that after a lifetime of linebreeding only the surface will be "scratched". This echos a sentiment of Dr. Whitney that a lifetime is not enough to do the work justice. Therefore, it becomes imperative that those who are engaged in this...

:stop: :cboy: Apparently Hereford Sire, there is a contingent here who's dander is raised due to our exchange. :cry: Invariably in my message board experiences, it seems whenever some few individuals put cohesive thoughts together that continue past a few lines of simpleton drivel, someone is...

HS wrote: That is a lot of animals to know trait origination if no two animals is the same or some are the same. That would be like looking at a chess board since there are 64 squares on the board, but there may be a gazillion differences in scatter bred cattle. If I take DNA samples from each...

Gberry, The traits of a heterzygous polled bull being passed is not only attributed to the bull himself, but from his ancestry also. Some traits like horns or polled, white faces, and others are well defined with "rules" that apply, because they have become "absolutely fixed" (homozygous) or...

Really liked this quote from Dr. Witherspoon on his site. He described some of what I was trying to state above with much more eloquence. "The point I am trying to make here is that if we become too absolute and too rigid about even important traits, we are going to inevitably sacrifice...

HS wrote: Maybe we can retire by buying culls of excellent bloodlines. I researched filial degeneration a tad, I what I have realized in thinking about this concept in the context of line breeding, ….. is if I use inexpensive initial seed stock, their progeny should revert to the mean and the...

FWIW......Animals at either the highest or lowest end of a bloodline rarely produce equals of themselves consistently. Rather, they tend to produce the average of their line due to a phenomenon known as filial degeneration. The high REA animal will probably not produce outstanding rib eye with...

The Lents' Anxiety 4th herd has been closed for 126 years. It surely can be done!

Heterosis isn't all roses either. Keep in mind that when you avail yourself of the advantages of heterozygosity, you're also sweeping all kinds of unexpressed genetic garbage under the rug. One day, those undesireable traits that are carried can and will surface randomly in the subsequent filial...

The Lents Anxiety 4th Herefords look outstanding on grass only. Couple that with the fact that they are the most genetically stable cattle on planet earth (as verified by DNA testing against other linebred strains such as Line Ones), and I don't think a man could go wrong buying there.

Maine Limi Man, I think linebreding and inbreeding are fascinating too. Dun you also made a very astute observation when you said : I feel the same way. I've always wanted to understand genetics better, so I've fooled with inbreeding starting with rats, and then dogs for 16 years now. Some...

Greenwillow, I think 50% is a safe percentage, and still allows one to narrow the gene pool and increase uniformity. On the other hand, with straight 50% stock and nothing tighter to infuse with the other segments of the family where that particular ancestor may be down to 25% or 12.5%, it...

Awesome project! My question is do you think that these Wagyu crossed with anything pure; whether Cont or Brit, would produce the same kind of carcass, or do you believe it is specific to the Charolais cross?

Nowadays don't most people just take their spouse to the "sale barn" in the end? :roll: Good point though Dee, I made the same point in another thread earlier this week. As breeders of any kind of livestock there will always be compromises of some kind or another that must be made to further...

Exactly my original point, his stock may produce best to outcross animals within the breed, rather than crossed toanother breed. The question at this point is how often is this same breeder's stock used with Angus cattle? If you say "all the time with great success", then it tends to isolate it...
